a) The average or mean slope of the function y = 2 - 5x² over the interval [-6, 3) is -45.
Determine the average?To find the average or mean slope of a function over an interval, we calculate the difference in the function values at the endpoints of the interval and divide it by the difference in the x-values.
In this case, the given function is y = 2 - 5x². To find the average slope over the interval [-6, 3), we evaluate the function at the endpoints: y₁ = 2 - 5(-6)² = -182 and y₂ = 2 - 5(3)² = -43. The corresponding x-values are x₁ = -6 and x₂ = 3.
The average slope is then calculated as (y₂ - y₁) / (x₂ - x₁) = (-43 - (-182)) / (3 - (-6)) = -45.
b) Using the Mean Value Theorem, we can find the exact value of the slope at some point c within the interval [-6, 3).
Determine the mean value?The Mean Value Theorem states that if a function is continuous on a closed interval [a, b] and differentiable on the open interval (a, b), then there exists a point c in (a, b) where the instantaneous rate of change (slope) is equal to the average rate of change over [a, b].
In this case, the function y = 2 - 5x² is continuous and differentiable on the interval (-6, 3). Therefore, there exists a point c within (-6, 3) where the instantaneous rate of change (slope) is equal to the average rate of change calculated in part a.

Evaluate the limit using L'Hôpital's rule et + 2.1 - 1 lim 20 6.6 Add Work Submit Question
The limit can be evaluated using L'Hôpital's rule. Applying L'Hôpital's rule to the given limit, we differentiate the numerator and the denominator with respect to t and then take the limit again.
Differentiating the numerator with respect to t gives 1, and differentiating the denominator with respect to t gives 0. Therefore, the limit of the given expression as t approaches 2.1 is 1/0, which is undefined.
L'Hôpital's rule can be used to evaluate limits when we have an indeterminate form, such as 0/0 or ∞/∞. However, in this case, the application of L'Hôpital's rule does not provide a finite result. The fact that the limit is undefined suggests that there is a vertical asymptote or a removable discontinuity at t = 2.1 in the original function. Further analysis or additional information about the function is necessary to determine the behavior around this point.

FILL THE BLANK. The period of the tangent and cotangent functions is _____. The period of the sine, cosine, cosecant, and secant functions is _____.
The period of the tangent and cotangent functions is π, while the period of the sine, cosine, cosecant, and secant functions is 2π.
The period of a trigonometric function is the length of one complete cycle of the function before it repeats itself. For the tangent and cotangent functions, their periods are π.
The tangent function, denoted as tan(x), is defined as the ratio of the sine function to the cosine function: [tex]$\tan(x) = \frac{{\sin(x)}}{{\cos(x)}}$[/tex]. The tan function has a period of π because it repeats its values every π radians or 180 degrees. This means that if you graph the tangent function, it will complete one cycle from 0 to π, and then repeat the same pattern.
Similarly, the cotangent function, denoted as cot(x), is the reciprocal of the tangent function: [tex]$\cot(x) = \frac{1}{{\tan(x)}}$[/tex]. Since the tangent function repeats every π radians, the cotangent function also has a period of π.
On the other hand, the sine, cosine, cosecant, and secant functions have a period of 2π. The sine function, denoted as sin(x), and the cosine function, denoted as cos(x), both complete one cycle from 0 to 2π before repeating their pattern. The cosecant function, cosec(x), is the reciprocal of the sine function, and the secant function, sec(x), is the reciprocal of the cosine function. Therefore, they also have a period of 2π.
In summary, the period of the tangent and cotangent functions is π, while the period of the sine, cosine, cosecant, and secant functions is 2π.

Find the t-value such that the area in the right tail is 0.25 with 9 degrees of freedom.
With 9 degrees of freedom, the t-value that corresponds to an area of 0.25 in the right tail is roughly 0.705.
The degrees of freedom (df) of the t-distribution, which in this case is nine, define it. The likelihood of receiving a t-value that is less than or equal to a specific value is provided by the cumulative distribution function (CDF) of the t-distribution. Finding the t-value for a particular region of the right tail is necessary, though.
The quantile function, commonly referred to as the percent-point function or the inverse of CDF, can be used to overcome this issue. We may determine the t-value that corresponds to that area by passing the desired area (0.25), the degrees of freedom (9), and the quantile function into the quantile function.

Consider the vector field F and the curve C below.
F(x, y) = x4y5i + x5y4j,

0 ≤ t ≤ 1
(a) Find a potential function f such that F = ∇f.
(b) Use part (a) to evaluate
(a) The potential function is f(x, y) = (1/5)x^5y^5 + C, where C is an arbitrary constant.
(b) The value of the line integral of F along the curve C is -243/5.
(a) To find a potential function f such that F = ∇f, we need to determine the function f(x, y) such that its partial derivatives with respect to x and y are equal to the components of F(x, y).
Given F(x, y) = x^4y^5i + x^5y^4j, we can integrate the components of F to find f(x, y):
∂f/∂x = [tex]x^4y^5[/tex]
∂f/∂y = [tex]x^5y^4[/tex]
Integrating the first equation with respect to x yields f(x, y) =[tex](1/5)x^5y^5[/tex] + g(y), where g(y) is a constant of integration that only depends on y.
Now, we differentiate this result with respect to y and set it equal to the second equation:
∂f/∂y = [tex]x^5y^4 = x^5y^4 + g'(y)[/tex]
Comparing the terms, we find that g'(y) = 0, which implies that g(y) is a constant.
Therefore, the potential function is f(x, y) = [tex](1/5)x^5y^5 + C[/tex], where C is an arbitrary constant.
(b) Using the potential function f(x, y) = (1/5)x^5y^5 + C from part (a), we can evaluate the line integral of F along the curve C by plugging in the parameterization of C into f and evaluating the difference of f at the endpoints.
C: r(t) = [tex]t^3 - 2t, t^3 + 2t,[/tex] 0 ≤ t ≤ 1
Evaluating f at the endpoints of C, we have:
f(r(1)) = [tex]f(1^3 - 2(1), 1^3 + 2(1)) = f(-1, 3) = (1/5)(-1)^5(3)^5 + C = -243/5 + C[/tex]
f(r(0)) = [tex]f(0^3 - 2(0), 0^3 + 2(0)) = f(0, 0) = (1/5)(0)^5(0)^5 + C = C[/tex]
Thus, the value of the line integral of F along C is:

(a) f(7) is undefined,
(b) Limit of f(x); lim(x → 7⁻) f(x) = 20.9,

To obtain the value of the function f(x) = (x² - 6x - 7) / (x - 7) for the given scenarios, let's evaluate each case separately:
(a) f(7):
To find f(7), we substitute x = 7 into the function:
f(7) = (7² - 6(7) - 7) / (7 - 7)
= (49 - 42 - 7) / 0
= 0 / 0
The expression is undefined at x = 7 because it results in a division by zero. Therefore, f(7) is undefined.
(b) Limit of f(x) as x approaches 7 from below (x → 7⁻):
To find this limit, we approach x = 7 from values less than 7. Let's substitute x = 6.9 into the function:
lim(x → 7⁻) f(x) = lim(x → 7⁻) [(x² - 6x - 7) / (x - 7)]
= [(6.9² - 6(6.9) - 7) / (6.9 - 7)]
= [(-2.09) / (-0.1)]
= 20.9
The limit of f(x) as x approaches 7 from below is equal to 20.9.
(c) Limit of f(x) as x approaches 7 from above (x → 7⁺):
To find this limit, we approach x = 7 from values greater than 7. Let's substitute x = 7.1 into the function:
lim(x → 7⁺) f(x) = lim(x → 7⁺) [(x² - 6x - 7) / (x - 7)]

Find the derivative
g(x) = 2x - cos (3 - 2x) - f(x) = 6 ln(7x2 + 1) + 3% =
The derivative of g(x) is 2 + 2sin(3 - 2x) - f'(x), and the derivative of f(x) is 84x/(7x^2 + 1) + 0.03.
To find the derivative of g(x), we differentiate each term separately. The derivative of 2x is 2, the derivative of cos(3 - 2x) is -2sin(3 - 2x) due to the chain rule, and the derivative of f(x) is obtained by differentiating ln(7x^2 + 1) using the chain rule, resulting in 84x/(7x^2 + 1). Finally, the derivative of 3% is 0.03.
To find the derivative of a function, we need to differentiate each term separately.
For the function g(x) = 2x - cos(3 - 2x) - f(x), we have three terms: 2x, cos(3 - 2x), and f(x).
The derivative of 2x is simply 2, as the derivative of x with respect to x is 1, and the derivative of a constant (2) is 0.
The term cos(3 - 2x) requires the application of the chain rule. The derivative of cos(u) is -sin(u), and when we differentiate the inner function (3 - 2x) with respect to x, we get -2. Therefore, the derivative of cos(3 - 2x) is -2sin(3 - 2x).
For the function f(x) = 6ln(7x^2 + 1) + 3%, we have one term: ln(7x^2 + 1).
To differentiate ln(7x^2 + 1), we apply the chain rule. The derivative of ln(u) is 1/u, and when we differentiate the inner function (7x^2 + 1) with respect to x, we get 14x. Therefore, the derivative of ln(7x^2 + 1) is (14x)/(7x^2 + 1).
Finally, the derivative of 3% is 0.03, as percentages can be treated as constant terms during differentiation.
So, the derivative of g(x) is 2 + 2sin(3 - 2x) - f'(x), where f'(x) represents the derivative of f(x), which is 6(14x)/(7x^2 + 1) + 0.03.

Therefore, with a 90% confidence level, we estimate that the proportion of the voting population that prefers candidate A is between 0.252 and 0.328, rounded to three decimal places.
To find the critical value for a confidence level of 95%, we use the standard normal distribution.
Since the sample size is large (600 people sampled), we can use the normal approximation to the binomial distribution. The formula for the confidence interval is:
Estimate ± (Critical Value) * (Standard Error)
In this case, we have 174 out of 600 people who preferred candidate A, so the proportion is 174/600 = 0.29.
To find the critical value, we need to determine the z-score corresponding to a 95% confidence level. Using a standard normal distribution table or a calculator, we find that the z-score for a 95% confidence level is approximately 1.96.
Next, we need to calculate the standard error. The formula for the standard error in this case is:
Standard Error = sqrt((p * (1 - p)) / n)
where p is the sample proportion (0.29) and n is the sample size (600).
Plugging in the values, we have:
Standard Error = sqrt((0.29 * (1 - 0.29)) / 600) ≈ 0.0195
Now, we can calculate the confidence interval:
0.29 ± (1.96 * 0.0195)
The lower bound of the confidence interval is 0.29 - (1.96 * 0.0195) ≈ 0.2519, and the upper bound is 0.29 + (1.96 * 0.0195) ≈ 0.3281.

To evaluate the integral ∫(VX-3) dx, we can use the substitution U = VX-3. The resulting integral will be in terms of U, and we can then solve it by integrating with respect to U.
Let's start by substituting U = VX-3. Taking the derivative of U with respect to X gives dU/dX = (VX-3)' = V. Solving this equation for dX gives dX = dU/V.
Substituting these values into the original integral, we have:
∫(VX-3) dx = ∫U (dX/V).
Now, we can rewrite the integral in terms of U and perform the integration:
∫U (dX/V) = ∫(U/V) dX.
Since dX = dU/V, the integral becomes:
∫(U/V) dX = ∫(U/V) (dU/V).
Now, we have a new integral in terms of U. We can simplify it by dividing U by V and integrating with respect to U:
∫(U/V) (dU/V) = ∫(1/V) dU.
Integrating ∫(1/V) dU gives ln|V| + C, where C is the constant of integration.

b lim (g(x) dx = K, Given the limit 6000 where K €1-00,00) and g(x) is a continuous, positive g(n)? decreasing function, what statement cannot be made about n=0 A. K can be any value on the interval
The statement that cannot be made about n = 0 is "K can be any value on the interval."
To understand why this statement cannot be made, let's analyze the given information. We know that the limit of the integral b lim (g(x) dx) as n approaches infinity is equal to K, where K is a specific value in the interval [0, 10000]. Additionally, g(x) is a continuous and positive decreasing function.
The fact that g(x) is a continuous and positive decreasing function implies that it approaches a finite limit as x approaches infinity. This means that as x increases, the values of g(x) become smaller and eventually stabilize around a certain value.
Now, when we consider the limit of the integral b lim (g(x) dx) as n approaches infinity, it represents the accumulation of the function g(x) over an increasing interval. As n becomes larger and larger, the interval over which we integrate g(x) expands.
Since g(x) is a decreasing function, the integral b lim (g(x) dx) will also approach a finite limit as n approaches infinity. This limit is the value K mentioned in the question. It represents the total accumulation of the function g(x) over the infinite interval.
However, it is important to note that as n approaches 0 (the lower limit of integration), the interval over which we integrate g(x) becomes smaller and smaller. This means that the value of the integral will be affected by the behavior of g(x) near x = 0.
Given that g(x) is a continuous and positive decreasing function, we can make certain observations about its behavior near x = 0. For example, we can say that g(x) approaches a finite positive value as x approaches 0. However, we cannot make any specific statements about the exact value of the integral at n = 0. It could be any value within the interval [0, K].
In summary, while we can make general statements about the behavior of g(x) and the limit of the integral as n approaches infinity, we cannot determine the exact value of the integral at n = 0. Therefore, the statement "K can be any value on the interval" cannot be made about n = 0.

fy(x, y) = d/dy (5x³ + 4x²y² - 3y² - 11)
Taking the derivative of each term separately:
fy(x, y) = d/dy (5x³) + d/dy (4x²y²) + d/dy (-3y²) + d/dy (-11)
Differentiating each term:
fy(x, y) = 0 + 8x²y + (-6y) + 0

= -17
Therefore, fx(-1, 2) = -17.
b) Evaluating fy(-1, 2):
Substituting x = -1 into fy(x, y):

Differentiating each term separately:
fx(x, y) = 1/(x - y) + 3x²y² + 0
Simplifying the expression, we have:
fx(x, y) = 1/(x - y) + 3x²y²
b) To find fy, we differentiate f(x, y) with respect to y while treating x as a constant:
fy(x, y) = d/dy (ln(x - y) + x³y²)

The problem involves determining the total output for maximizing the manufacturer's revenue, finding the prices of the products at which profit is maximized, and comparing the price elasticities of demand in the domestic and foreign markets when profit is maximized.
a) To maximize the manufacturer's revenue, we need to find the total output at which the revenue is maximized. The revenue can be calculated by multiplying the output in each market by its respective price. So, the total revenue (TR) is given by TR = Qo * Po + QF * PF. To maximize the revenue, we differentiate TR with respect to the total output and set it equal to zero. By solving the resulting equation, we can determine the total output at which the manufacturer's revenue is maximized.

evaluate the line integral, where c is the given curve. c x sin(y) ds, c is the line segment from (0, 2) to (4, 5)
The solution of the line integral [tex]\int\limits t \sin(2+3t) , dt[/tex].
What is integral?
The value obtained after integrating or adding the terms of a function that is divided into an infinite number of terms is generally referred to as an integral value.
To evaluate the line integral of the function f(x, y) = xsin(y) along the curve C which is the line segment from (0,2) to (4,5), we can parameterize the curve and then compute the integral.
Let's parameterize the curve
C with a parameter t such that x(t) and y(t) represent the x and y coordinates of the curve at the parameter value t.
Given that the curve is a line segment, we can use a linear interpolation between the initial and final points.
The parameterization is as follows:
x(t)=(1−t)⋅0+t⋅4=4t
y(t)=(1−t)⋅2+t⋅5=2+3t
Now, we can compute the line integral using the parameterization:
[tex]\int_{C} x \sin(y) , ds = \int_{a}^{b} f(x(t), y(t)) \cdot \left(x'(t)^2 + y'(t)^2\right) , dt[/tex]
where a and b are the parameter values corresponding to the initial and final points of the curve.
Substituting the parameterization and evaluating the integral, we have:
[tex]\int_{C} x \sin(y) , ds = \int_{0}^{1} (4t) \sin(2+3t) \cdot \left(4^2 + 3^2\right) , dt[/tex]
To evaluate this integral, numerical methods or approximations can be used.
To evaluate the given integral, we need to perform the integration on both sides of the equation.
On the left-hand side:
[tex]\int\limit_{C} x \sin(y) ds[/tex]
On the right-hand side:
[tex]\int\limits_0^{1} (4t) \sin(2+3t) \cdot (4^2 + 3^2) , dt[/tex]
Let's start by evaluating the integral on the right-hand side. The integral can be simplified as follows:
[tex]\int\limits_0^{1} (4t) \sin(2+3t) \cdot (4^2 + 3^2) , dt= 49 \int\limits_{0}^{1} t \sin(2+3t) , dt[/tex]
Unfortunately, the integral [tex]\int\limits t \sin(2+3t) , dt[/tex] does not have a simple closed-form solution. It requires numerical integration techniques or approximation methods to evaluate it.
However, it is important to note that the left-hand side of the equation is also in integral form and represents the length of curve C. Without knowing the specific curve C, it is not possible to evaluate the left-hand side of the equation without further information.
Therefore, the given integral cannot be evaluated without additional details about the curve C or without using numerical methods for approximating the right-hand side integral.
Hence, the solution of the line integral [tex]\int\limits t \sin(2+3t) , dt[/tex].

We want to use the Alternating Series Test to determine if the series: 00 2ܨ Σ(-1)* + 2 k=4 25 + 3 converges or diverges. We can conclude that: The series diverges by the Alternating Series Test. Th
We are given a series Σ((-1)^k+2)/(25 + 3k) and we want to determine if it converges or diverges using the Alternating Series Test. The conclusion is that the series diverges based on the Alternating Series Test.
To apply the Alternating Series Test, we need to check two conditions: the terms of the series must alternate in sign, and the absolute values of the terms must decrease as k increases.
In the given series, the terms alternate in sign due to the (-1)^k term. However, to determine if the absolute values of the terms decrease, we can rewrite the series as Σ((-1)^k+2)/(25 + 3k) = Σ((-1)^(k+2))/(25 + 3k).
Now, let's consider the absolute values of the terms. As k increases, the denominator 25 + 3k also increases. Since the numerator (-1)^(k+2) alternates between -1 and 1, the absolute values of the terms do not decrease as k increases.
According to the Alternating Series Test, for a series to converge, the terms must alternate in sign and the absolute values must decrease. Since the absolute values of the terms in the given series do not decrease, we can conclude that the series diverges.
Therefore, the series Σ((-1)^k+2)/(25 + 3k) diverges based on the Alternating Series Test.

To determine f'(x) for the function f(x) = 4x + 7 using the definition of the derivative, the Newton quotient is computed and simplified to eliminate h in the denominator.
The derivative of a function f(x) can be found using the definition of the derivative, which involves the Newton quotient. For the function f(x) = 4x + 7, we calculate f'(x) by evaluating the Newton quotient.
The Newton quotient is given by (f(x + h) - f(x)) / h, where h represents a small change in x.
Substituting f(x) = 4x + 7 into the Newton quotient, we have [(4(x + h) + 7) - (4x + 7)] / h.
Simplifying the expression inside the numerator, we get (4x + 4h + 7 - 4x - 7) / h.
Canceling out the terms that have opposite signs, we are left with (4h) / h.
Now, we can cancel out the h in the numerator and denominator, resulting in the derivative f'(x) = 4.
Therefore, the derivative of the function f(x) = 4x + 7 with respect to x, denoted as f'(x), is equal to 4.

These are the cost and revenue functions for a line of 24-pound bags of dog food sold by a large distributor:
R(x) = -31.72x2 + 2,030x
C(x) = -126.96x + 26,391
The maximum profit of $
can be made when the selling price of the dog food is set to $
per bag.
Answer:
The profit function P(x) is defined as the difference between the revenue function R(x) and the cost function C(x): P(x) = R(x) - C(x). Substituting the given functions for R(x) and C(x), we get:
P(x) = (-31.72x^2 + 2030x) - (-126.96x + 26391) = -31.72x^2 + 2156.96x - 26391
To find the maximum profit, we need to find the vertex of this quadratic function. The x-coordinate of the vertex is given by the formula x = -b/(2a), where a = -31.72 and b = 2156.96. Substituting these values into the formula, we get:
x = -2156.96/(2 * (-31.72)) ≈ 34
Substituting this value of x into the profit function, we find that the maximum profit is:
P(34) = -31.72(34)^2 + 2156.96(34) - 26391 ≈ $4,665
The selling price of the dog food is given by the revenue function divided by x: R(x)/x = (-31.72x^2 + 2030x)/x = -31.72x + 2030. Substituting x = 34 into this equation, we find that the selling price of the dog food should be set to:
-31.72(34) + 2030 ≈ $92
So, the maximum profit of $4,665 can be made when the selling price of the dog food is set to $92 per bag.

•8(1.5)=g(4)=-214-2+4=0
• g'(1.5)= g(0)=-20-2+4=0
Using the function g(x) = -2|r-2| + 4 and the initial value of 1.5, the iterations lead to the results: g(1.5) = 3, g(3) = 2, g'(1.5) = 4, g(4) = 0, and g'(1.5) = 0.
We start with the initial value of x = 1.5 and apply the function g(x) = -2|r-2| + 4 to it.
g(1.5) = -2|1.5-2| + 4 = -2|-0.5| + 4 = -2(0.5) + 4 = 3.
Next, we substitute the result back into the function: g(3) = -2|3-2| + 4 = -2(1) + 4 = 2.
Taking the derivative of g(x) with respect to x, we have g'(x) = -2 if x ≠ 2. So, g'(1.5) = g(2) = -2|2-2| + 4 = 4.
Continuing the iteration, g(4) = -2|4-2| + 4 = -2(2) + 4 = 0.
Finally, g'(1.5) = g(0) = -2|0-2| + 4 = 0.

x' evaluated at the point (-1,1) is equal to 3/5.
To find x' for x(t) defined implicitly by the equation x⁴ + t⁴x + t - 3 = 0, we can differentiate both sides of the equation with respect to t using implicit differentiation.
Differentiating x⁴ + t⁴x + t - 3 with respect to t:
4x³ * dx/dt + t⁴ * dx/dt + 4t³x + 1 = 0
Rearranging the terms:
dx/dt (4x³ + t⁴) = -4t³x - 1
Now we can solve for dx/dt (x'):
dx/dt = (-4t³x - 1) / (4x³ + t⁴)
To evaluate x' at the point (-1,1), we substitute t = -1 and x = 1 into the expression for dx/dt:

Let's analyze each series in detail:
The series (-1)^(n+2n) * -1:
This series can be written as (-1)^(3n) * (-1). We can see that the exponent (3n) is always divisible by 3, so (-1)^(3n) will alternate between 1 and -1. The series is multiplied by (-1), so the signs will alternate again. The series becomes: 1, -1, 1, -1, ...
This series satisfies the conditions for the alternating series test since the terms alternate in sign and the absolute value of the terms decreases as n increases. Therefore, the series converges by the alternating series test.
The series (-1)^(n+1) + 7:
This series does not follow the form required for the alternating series test. The alternating series test applies to series where the terms alternate in sign. However, in this series, the terms do not alternate in sign. Therefore, we cannot apply the alternating series test to determine the convergence or divergence of this series.
The series (-1)^n * cos(tn):
This series does not satisfy the requirements for the alternating series test. The alternating series test applies to series where the terms alternate in sign, but in this series, the sign of the terms depends on the value of cos(tn), which can be positive or negative. Therefore, we cannot apply the alternating series test to determine the convergence or divergence of this series.
The series (-1)^(n+1) / n^2:
This series follows the form required for the alternating series test. The terms alternate in sign, and the absolute value of the terms decreases as n increases because n^2 is in the denominator. Therefore, the series converges by the alternating series test.
The series 1/((n+1)^2):
This series does not follow the form required for the alternating series test. The alternating series test applies to series where the terms alternate in sign, but in this series, all the terms are positive. Therefore, we cannot apply the alternating series test to determine the convergence or divergence of this series.
The series (-1)^(n+1) + 1:

[tex]\int\limits^2_0 (1/3)sec(x) dx[/tex]
To evaluate this integral, we can use the formula for the integral of the secant function:
∫sec(x)dx = ln |sec(x) + tan(x)| + C
Applying this formula to our integral, we get:
[tex](1/3)\int\limits^2_0 {sec(x)} \, dx[/tex]
= (1/3)[ln |sec(2) + tan(2)| - ln |sec(0) + tan(0)| ]
Since sec(0) = 1 and tan(0) = 0, the second term becomes zero:
(1/3)[ln |sec(2) + tan(2)| - ln(1)]
= (1/3) ln |sec(2) + tan(2)|
Therefore, the exact value of the integral is (1/3) ln |sec(2) + tan(2)|.

Given that yı = e-t is a solution of the equation, ty" + (3t - 1)y + (2t - 1)y = 0, t > 0 find a second linearly independent solution using the reduction of order method.
The second linearly independent solution of the equation ty" + (3t - 1)y + (2t - 1)y = 0, where t > 0 and yı = e^-t is a solution, can be found using the reduction of order method. The second solution is [tex]y_2 = te^{-t}[/tex].
To find the second solution using the reduction of order method, we assume the second solution has the form y2 = u(t) * y1, where y1 = e^-t is the given solution.
We differentiate y2 with respect to t to find y2' and substitute it into the differential equation:
[tex]y_2' = u(t) * y_1' + u'(t) * y_1[/tex]
Plugging in [tex]y_1 = e^{-t}[/tex] and [tex]y_1' = -e^{-t}[/tex], we have:
[tex]y_2' = u(t) * (-e^{-t}) + u'(t) * e^{-t}[/tex]
Now we substitute y2 and y2' back into the differential equation:
[tex]t * (u(t) * (-e^{-t}) + u'(t) * e^{-t}) + (3t - 1) * (t * e^{-t}) + (2t - 1) * (te^{-t}) = 0[/tex]
Expanding and rearranging terms, we get:
[tex]t * u'(t) * e^{-t} = 0[/tex]
Since t > 0, we can divide both sides of the equation by t and e^-t to obtain:
u'(t) = 0
Integrating both sides with respect to t, we find:
u(t) = c
where c is an arbitrary constant. Therefore, the second linearly independent solution is [tex]y_2 = e^{-t}[/tex], where [tex]y_1 = e^{-t}[/tex] is the given solution.
In summary, using the reduction of order method, we find that the second linearly independent solution of the given differential equation is [tex]y_2 = e^{-t}[/tex].
