the derivative of the function y = 5 log₅ (x⁴ - 7) with respect to x is (20x³) / ((x⁴ - 7) * ln(5)).

To calculate the derivative of the function y = 5 log₅ (x⁴ - 7), we can use the chain rule.

Let's denote the inner function as u = x⁴ - 7. Applying the chain rule, the derivative can be found as follows:

dy/dx = dy/du * du/dx

First, let's find the derivative of the outer function 5 log₅ (u) with respect to u:

(dy/du) = 5 * (1/u) * (1/ln(5))

Next, let's find the derivative of the inner function u = x⁴ - 7 with respect to x:

(du/dx) = 4x³

Now, we can multiply these two derivatives together:

(dy/dx) = (dy/du) * (du/dx)

        = 5 * (1/u) * (1/ln(5)) * 4x³

Since u = x⁴ - 7, we can substitute it back into the expression:

(dy/dx) = 5 * (1/(x⁴ - 7)) * (1/ln(5)) * 4x³

Simplifying further, we have:

(dy/dx) = (20x³) / ((x⁴ - 7) * ln(5))

(a) There is no value of m for which [tex]f(x) = x^m[/tex] is a solution to the equation [tex]2x^2(dy/dx) + 7x + 4y = 0.[/tex]

(b) For the equation d²y/dx² - x(dy/dx) - 27y = 0, the function[tex]f(x) = x^m[/tex] is a solution when m = 0 or m = 1.

To determine for which values of m the function [tex]f(x) = x^m[/tex] is a solution to the given differential equation, we need to substitute the function f(x) into the differential equation and check if it satisfies the equation for all values of x.

(a) For the equation [tex]2x^2(dy/dx) + 7x + 4y = 0[/tex]:

Substituting [tex]f(x) = x^m[/tex] and its derivative into the equation:

[tex]2x^2 * (mf(x)) + 7x + 4(x^m) = 0[/tex]

[tex]2m(x^(m+2)) + 7x + 4(x^m) = 0[/tex]

For f(x) = x^m to be a solution, this equation must hold true for all x. Therefore, the coefficients of the terms with the same powers of x must be equal to zero. This leads to the following conditions:

[tex]2m = 0 (coefficient of x^(m+2))[/tex]

[tex]7 = 0 (coefficient of x^1)[/tex]

[tex]4 = 0 (coefficient of x^m)[/tex]

From the above conditions, we can see that there is no value of m that satisfies all three conditions simultaneously. Therefore, there is no value of m for which f(x) = x^m is a solution to the given differential equation.

(b) For the equation d²y/dx² - x(dy/dx) - 27y = 0:

Substituting[tex]f(x) = x^m[/tex] and its derivatives into the equation:

[tex](m(m-1)x^(m-2)) - x((m-1)x^(m-2)) - 27(x^m) = 0[/tex]

Simplifying the equation:

[tex]m(m-1)x^(m-2) - (m-1)x^m - 27x^m = 0[/tex]

Again, for[tex]f(x) = x^m[/tex] to be a solution, the coefficients of the terms with the same powers of x must be equal to zero. This leads to the following conditions:

[tex]m(m-1) = 0 (coefficient of x^(m-2))[/tex]

[tex](m-1) - 27 = 0 (coefficient of x^m)[/tex]

Solving the first equation, we have:

m(m-1) = 0

m = 0 or m = 1

Substituting m = 0 and m = 1 into the second equation, we find that both values satisfy the equation. Therefore, for m = 0 and m = 1, the function f(x) = x^m is a solution to the given differential equation.

The surface integral of Sszds over the hemisphere S, given by z² + y² + z² = 1 with z ≥ 0, evaluates to zero.

To evaluate the surface integral, we first parameterize the hemisphere S. We can use spherical coordinates to do this. Let's use the parameterization:

x = ρsinφcosθ

y = ρsinφsinθ

z = ρcosφ

where 0 ≤ ρ ≤ 1, 0 ≤ φ ≤ π/2, and 0 ≤ θ ≤ 2π.

The surface integral s Sszds can then be expressed as s ∫∫ρ²cosφρ²sinφdρdθ.

We need to determine the limits of integration for ρ and θ. For ρ, since the hemisphere is bounded by the equation z² + y² + z² = 1, we have ρ² + ρ²cos²φ = 1. Simplifying, we find ρ = sinφ. For θ, we can integrate over the full range 0 ≤ θ ≤ 2π.

Now, let's evaluate the surface integral:

s ∫∫ρ²cosφρ²sinφdρdθ = ∫[tex]₀^(2π)[/tex] ∫[tex]₀^(π/2)[/tex] (ρ⁴cosφsinφ) dφdθ.

To find an nth degree polynomial function with real coefficients satisfying the given conditions, we can start by using the zeros to determine the factors of the polynomial.

Since -4 and i are zeros, we know that the factors are (x + 4) and (x - i) = (x + i). Since i is a complex number, its conjugate, -i, is also a zero.

So, the factors of the polynomial are (x + 4), (x + i), and (x - i). To find the polynomial function, we multiply these factors together:

f(x) = (x + 4)(x + i)(x - i)

Expanding this expression gives:

f(x) = (x + 4)(x² - i²)

= (x + 4)(x² + 1)

= x³ + 4x² + x + 4x² + 16 + 4

= x³ + 8x² + x + 20

Using Simpson's rule with n = 1, we can approximate the integral of the function f(x) = 1 + x^3 over the interval [3, 8].

Simpson's rule is a numerical method for approximating definite integrals using quadratic polynomials. It divides the interval into subintervals and approximates the integral using a weighted average of the function values at the endpoints and midpoint of each subinterval.

Given n = 1, we have two subintervals: [3, 5] and [5, 8]. The width of each subinterval, h, is (8 - 3) / 2 = 2.

We can now calculate the approximate value of the integral using Simpson's rule formula:

Approximate integral ≈ (h/3) * [f(a) + 4f(a + h) + f(b)],

where a and b are the endpoints of the interval.

Plugging in the values:

Approximate integral ≈ (2/3) * [f(3) + 4f(5) + f(8)],

≈ (2/3) * [(1 + 3^3) + 4(1 + 5^3) + (1 + 8^3)].

What is area bounded by the curve?

The length of the appropriate arc of the curve is equal to the area enclosed by a curve, its axis of coordinates, and one of its points.

As given curve is,

y = x² for 0 ≤ x ≤ 2

From the given data,

The constant density of a metal plate is 3 g/cm². The metal plate as a shape bounded by the curve y = x² and the x-axis.

(a). Evaluate the total mass of the plate:

The area of the plate is A = ∫ from (0 to 2) y dx

A = ∫ from (0 to 2) x² dx

A = from (0 to 2) [x³/3]

A = [(2³/3) -(0³/3)]

A = 8/3.

Hence, the area of the plate is A = 8/3 cm².

and also, the mass is = area of the plate × plate density

Mass = 8/3 cm² × 3 g/cm²

Mass = 8g.

(b). The sketch of the required region shown below.

(c). Evaluate the value of bar-x:

Slice the region into vertical strips of width Δx.

Now, the area of strips = Aₓ(x) × Δx

                                      = x²Δx

Now, the required value of bar-x = [∫xδ Aₓ dx]/Mass

bar-x = [∫xδ Aₓ dx]/Mass.

Substitute values,

bar-x = [∫from (0 to 2) xδ Aₓ dx]/Mass

bar-x = [3∫from (0 to 2) x³ dx]/8

bar-x = [3/8 ∫from (0 to 2) x³ dx]

Solve integral,

bar-x = [3/8 {from (0 to 2) x⁴/4}]

bar-x = 3/8 {(2⁴/4) -(0⁴/4)}

bar-x = 3/8 {4 - 0}

bar-x = 3/2.

The amount of money that can be expected to be saved is $166,140. f(x, y) = -3x'y' - 5xy', and ∂f/∂x = -3(y')(dx'/dy) - 5y(d/dx)(x), and ∂f/∂y = -3(x')(dy/dx) - 5x(d/dy)(y).

Suppose you graduate, begin working full time in your new career and invest $1,300 per month to start your own business after working 10 years in your field.

Assuming you get a return on your investment of 6.5%, the amount of money that can be expected to be saved can be calculated as follows:

Yearly Investment = $1,300 × 12 months= $15,600

Per Annum Return on Investment = 6.5%

Therefore, Annual Return on Investment = 6.5% of $15,600= 0.065 × $15,600= $1,014

Total Amount of Investment = $1,300 × 12 × 10= $156,000

Total Amount of Interest = 10 × $1,014= $10,140

Total Amount Saved = $156,000 + $10,140= $166,140.

Hence, the amount of money that can be expected to be saved is $166,140.

Given f(x, y) = -3x'y' - 5xy', we can find f as follows:

For a given function, f(x, y), partial differentiation is obtained by keeping one variable constant and differentiating the other.

Using the above method, let's find ∂f/∂x

First, we differentiate f(x, y) with respect to x by assuming y to be constant. Here is the step-by-step approach:

∂f/∂x = -3(y')(d/dx)(x') - 5y(d/dx)(x)

Since x is a function of y, we use the chain rule for differentiation to differentiate x.

Therefore, (d/dx)(x') = dx'/dy

Substituting the value of (d/dx)(x') in the above equation, we get

∂f/∂x = -3(y')(dx'/dy) - 5y(d/dx)(x)

Now, we differentiate f(x, y) with respect to y by assuming x to be constant. Here is the step-by-step approach:

∂f/∂y = -3(x')(d/dy)(y') - 5x(d/dy)(y)

Since y is a function of x, we use the chain rule for differentiation to differentiate y.

Therefore, (d/dy)(y') = dy/dx(d/dy)(y') = d/dx(x)

Substituting the value of (d/dy)(y') in the above equation, we get

∂f/∂y = -3(x')(dy/dx) - 5x(d/dy)(y)

Hence, f(x, y) = -3x'y' - 5xy', and ∂f/∂x = -3(y')(dx'/dy) - 5y(d/dx)(x), and ∂f/∂y = -3(x')(dy/dx) - 5x(d/dy)(y).

The flux of the vector field is Flux = ∫∫S (-y^7 + xy) dy dz

To find the flux of the vector field F = (-y^7 + xy) through the given surface S, we can use the surface integral formula:

Flux = ∬S F · dA,

where dA is the vector differential area element.

The surface S is a square plate in the yz plane with corners at (0, 2, 2), (0, -2, 2), (0, 2, -2), and (0, -2, -2), oriented in the positive x direction.

Since the surface is in the yz plane, the x-component of the vector field F does not contribute to the flux. Therefore, we only need to consider the yz components.

We can parameterize the surface S as follows:

r(y, z) = (0, y, z), with -2 ≤ y ≤ 2 and -2 ≤ z ≤ 2.

The outward unit normal vector to the surface S is n = (1, 0, 0) since the surface is oriented in the positive x direction.

Now, we can calculate the flux by evaluating the surface integral:

Flux = ∬S F · dA = ∬S (-y^7 + xy) · n dA.

Since n = (1, 0, 0), the dot product simplifies to:

F · n = (-y^7 + xy) · (1) = -y^7 + xy.

Therefore, the flux becomes:

Flux = ∬S (-y^7 + xy) dA.

To evaluate the surface integral, we need to compute the area element dA in terms of the variables y and z. Since the surface S is in the yz plane, the area element is given by:

dA = dy dz.

Now we can rewrite the flux integral as:

Flux = ∫∫S (-y^7 + xy) dy dz,

where the limits of integration are -2 ≤ y ≤ 2 and -2 ≤ z ≤ 2.

Evaluating this double integral will give us the flux of the vector field through the surface S.

The power series representation for f(x) when the index variable of the summation n = 0, is Σ((-1)^(n+2) * (x-3)^(n+2))/(n+2) from n=0 to ∞.

To find the power series representation for f(x), we start by recognizing that f(x) is equal to the sum of terms with coefficients (-1)^(n+2) and powers of (x-3) raised to (n+2). This suggests using a power series of the form Σ(c_n * (x-a)^n), where c_n represents the coefficients and (x-a) represents the power of x.

By substituting a=3, we obtain Σ((-1)^(n+2) * (x-3)^(n+2))/(n+2), where the index variable n starts from 0 and the summation extends to infinity. This power series provides an approximation of f(x) in terms of the given coefficients and powers of (x-3).

If a rectangular prism is 18.2 feet long and 16 feet wide and its volume is 3,494.4 cubic feet then height is 12 feet.

To find the height of the rectangular prism, we can use the formula for the volume of a rectangular prism, which is:

Volume = Length × Width × Height

Given that the length is 18.2 feet, the width is 16 feet, and the volume is 3,494.4 cubic feet, we can rearrange the formula to solve for the height:

Height = Volume / (Length × Width)

Plugging in the values:

Height = 3,494.4 cubic feet / (18.2 feet × 16 feet)

Height = 3,494.4 cubic feet / 291.2 square feet

Height = 12 feet

Therefore, the height of the rectangular prism is approximately 12 feet.

The angle e can be found by taking the inverse cosecant (csc^-1) of 4.0592. After evaluating this inverse function, the angle e is approximately 72 degrees and 3 minutes.

Given csc e = 4.0592, we can determine the angle e by taking the inverse cosecant (csc^-1) of 4.0592. The inverse cosecant function, also known as the arcsine function, gives us the angle whose cosecant is equal to the given value.

Using a calculator, we can find csc^-1(4.0592) ≈ 72.0509 degrees. However, we need to express the angle e in degrees and minutes, rounded to the nearest minute.

To convert the decimal part of the angle, we multiply the decimal value (0.0509) by 60 to get the corresponding minutes. Therefore, 0.0509 * 60 ≈ 3.0546 minutes. Rounding to the nearest minute, we have 3 minutes.

Thus, the angle e is approximately 72 degrees and 3 minutes.

When a ladder is resting against a vertical wall and making an angle of 70° from the horizontal ground the value of e is 1.12 inches.

Given that A ladder is resting against a vertical wall and making an angle of 70° from the horizontal ground and its lower ground is 0.8 inches away from the wall. When the top of the ladder slides down by 1 inch. To find:

We are to determine the value of e and create a diagram of the problem.

As we know that a ladder is resting against a vertical wall and making an angle of 70° from the horizontal ground.

Therefore, the angle made by the ladder with the wall is 90°.

So, the angle made by the ladder with the ground will be 90° - 70° = 20°.

Let the height of the wall be "x" and the length of the ladder be "y".

So, we have to determine the value of e, which is the distance between the ladder and the wall.

Using the trigonometric ratio in the triangle, we have; Sin 70° = x / y => x = y sin 70° [1]

And, cos 70° = e / y => e = y cos 70° [2]

It is given that the top of the ladder slides down by 1 inch.

Now, the ladder makes an angle of 60° with the horizontal.

So, the angle made by the ladder with the ground will be 90° - 60° = 30°.

Using the trigonometric ratio in the triangle, we have; Sin 60° = x / (y - 1) => x = (y - 1) sin 60°[3]

And, cos 60° = e / (y - 1) => e = (y - 1) cos 60°[4]

Comparing equation [1] and [3], we get; y sin 70° = (y - 1) sin 60°=> y = (sin 60°) / (sin 70° - sin 60°) => y = 3.64 in

Putting the value of y in equation [2], we get; e = y cos 70° => e = 1.12 in

The limit of the sequence bn = (1 + (1.7/n))n is e.

To find the limit of the sequence whose terms are given by bn = (1 + (1.7/n))n, we can use the formula for the number e as a limit.

By expressing the given sequence in terms of the natural logarithm and utilizing the properties of limits, we can simplify the expression and ultimately find that the limit is equal to e.

The result shows that as n becomes larger, the terms of the sequence approach the value of e.

lim n→∞ (1 + (1.7/n))n

= e^(lim n→∞ ln(1 + (1.7/n))n)

= e^(lim n→∞ n ln(1 + (1.7/n))/n)

= e^(lim n→∞ ln(1 + (1.7/n))/((1/n)))

= e^(lim x→0 ln(1 + 1.7x)/x) [where x = 1/n]

= e^[(d/dx ln(1 + 1.7x))(at x=0)]

= e^(1/(1+0))

= e
