Multiplying polynomials 4n2(n2 + 5n - 8)

Answers

Answer 1

Answer:

4n^4 + 20n^3 - 32n^2

Step-by-step explanation:

We have to distribute 4n2 to each term.

4n2 x n2. We can multiply the two n2 together resulting in 4n^4.

Now we do 4n2 x 5n. Here we multiply 4 x 5 which equals 20. Then, we multiply the n2 and n. Which results in n^3. Now we put them together; 20n^3.

Finally, we multiply 4n2 by -8. Since 8 doesn't have any variables, we just multiply the 4 and -8. Which equals to -32, now we just combine -32 and the variable; -32n2.

Now we combine these terms together. Our final answer is, 4n^4 + 20n^3 -32n^2.

5. The minimum value of g(x) is -8.

The maximum value of g(x) is 17.

6. The average rate of change of the function g(x) over the interval [-2, 3] is 5.

How to determine the maximum and minimum value?

By critically observing the table representing the function g(x), we can logically deduce the following minimum value and maximum value over the interval [-2, 3];

When x = -2, the minimum value of g(x) is equal to -8.

When x = 0, the maximum value of g(x) is equal to 17.

Question 6.

In Mathematics, the average rate of change of f(x) on a closed interval [a, b] is given by this mathematical expression:

Average rate of change = [f(b) - f(a)]/(b - a)

Next, we would determine the average rate of change of the function g(x) over the interval [-2, 3]:

a = -2; f(a) = -8

b = 3; f(b) = 17

Average rate of change = (17 + 8)/(3 + 2)

(c) The area of the surrounding is 0.8844 meters square.

Area of the office floor= Length × Breadth

                                     = 8.5 meters × 6.3 meters

                                     = 53.55 meters square

Area of the Carpet = Length × Breadth

                               = (8.5-0.06) meters × (6.3-0.06) meters

What is the correct order of the functions from least to greatest according to the average rate of
change on the interval from x=-1 to x-3? (2 points)

Answers

The correct option is the second one, the order is:

g(x), f(x), h(x).

How to find the rates of change?

To find the rate of change for a function f(x) on an interval [a, b] we need to get:

R = (f(b) - f(a))/(b - a)

Here the interval is [-1, 3]

The first function is:

f(x)=  (x + 3)² - 2

Evaluating we get:

f(-1) = (-1 + 3)² - 2

f(-1) = 2² - 2 = 4 -2 = 2

and f(3) = (3 + 3)² - 2 = 34

Then the rate is:

R = (34 - 2)/(3 + 1) = 8

For g(x) we can use the graph, we have:

R = (0 + 2)/4 = 1/2

For the last function we need to use the table, then we will get:

R = (62 - 14)/(3 + 1) = 12

Then the order, from least to greatest is:

g(x), f(x), h(x).

dollars of the company as a function of x?

Answers

The sound emitted from the jet plane has a sound intensity of approximately 149.13 decibels.

How to find determine the expression models the profit in dollars of the company as a function of x

Using the formula:

D = 10 * log(I/I0),

where D represents the sound intensity in decibels, I is the given sound intensity, and I0 is the reference intensity of 10^-12 watts per square meter.

Substituting the given values:

D = 10 * log(8.2*10^2 / 10^-12).

To simplify the calculation, we can rewrite the division as multiplication by the reciprocal:

D = 10 * log(8.2*10^2 * 10^12).

Using the logarithm property log(a * b) = log(a) + log(b):

D = 10 * (log(8.2) + log(10^2) + log(10^12)).

Using the logarithm property log(a^b) = b * log(a):

D = 10 * (log(8.2) + 2 * log(10) + 12 * log(10)).

Since log(10) = 1:

D = 10 * (log(8.2) + 2 + 12).

D = 10 * (log(8.2) + 14).

Using a calculator or logarithm table, we can find log(8.2) ≈ 0.913.

D = 10 * (0.913 + 14).

D = 10 * 14.913.

D ≈ 149.13.

Therefore, the sound emitted from the jet plane has a sound intensity of approximately 149.13 decibels.

Aubree owns a small business selling clothing. She knows that in the last week 69 customers paid cash, 2 customers used a debit card, and 7 customers used a credit card. Based on these results, express the probability that the next customer will pay with something other than cash as a percent to the nearest whole number.

Answers

The probability that the next customer will pay with something other than cash, rounded to the nearest Whole number, is approximately 12%.

The probability that the next customer will pay with something other than cash, we need to consider the total number of customers who paid with something other than cash and divide it by the total number of customers in the last week.

In the given information, it is stated that 69 customers paid with cash, 2 customers used a debit card, and 7 customers used a credit card. To find the total number of customers who paid with something other than cash, we add the number of customers who used a debit card and the number of customers who used a credit card:

Total number of customers who paid with something other than cash = Number of customers who used a debit card + Number of customers who used a credit card

= 2 + 7

= 9

Now, to calculate the probability, we divide the number of customers who paid with something other than cash by the total number of customers:

Probability = Number of customers who paid with something other than cash / Total number of customers

= 9 / (69 + 2 + 7)

= 9 / 78

= 0.1154 (rounded to four decimal places)

To express the probability as a percentage, we multiply the probability by 100:

Probability as a percent = 0.1154 * 100

≈ 11.54

Therefore, the probability that the next customer will pay with something other than cash, rounded to the nearest whole number, is approximately 12%.

We have,

To find the derivative of the function [tex]f(w) = 2/(w^2 - 4)^5[/tex], we can use the chain rule and the power rule for differentiation.

Let's go through the steps:

First, rewrite the function as [tex]f(w) = 2(w^2 - 4)^{-5}.[/tex]

Now, let's differentiate f(w) with respect to w:

[tex]f'(w) = d/dw~ [2(w^2 - 4)^{-5}][/tex]

To apply the chain rule, we need to differentiate the outer function and multiply it by the derivative of the inner function.

Using the power rule, the derivative of (w² - 4) with respect to w is 2w.

Applying the chain rule:

Erica bought a road bike using the store’s payment plan. She made a $320 down payment and makes monthly payments of $91. If the total cost is $1,867, how many months will Erica be paying for the bike?

Answers

The total cost of the bike is $1,867, and Erica made a down payment of $320. This means that she still owes:

$1,867 - $320 = $1,547

Each month, Erica pays $91 towards the cost of the bike. To find out how many months she will be paying, we need to divide the remaining cost by the monthly payment:

$1,547 ÷ $91/month ≈ 17 months

So Erica will be paying for the bike for approximately 17 months.

Answer: 17 months

Step-by-step explanation:

Total cost of the bike = $1,867

Down payment = $320

so $1,867 - $320 = $1,547

$91 * 17 = 1,547

(17 = months) so $91 * 17 months = 1,547

The missing angles are m ∠1 = 53° and m ∠k = 12°.

Given that are two circles we need to find the missing measures,

Using the concept of intersecting chords angles,

When two chords intersect inside a circle, the angle between the chords is half the sum of the intercepted arcs.

And,

When two chords intersect outside a circle, the angle between the chords is half the difference of the intercepted arcs.

So,

a) m ∠1 = 1/2 [arc LP + arc RQ]

m ∠1 = 1/2 [50°+56°]

m ∠1 = 1/2 × 106°

m ∠1 = 53°

b) m ∠k = 1/2 [arc MJ - arc LR]

arc LR = 360° - [72° + 100° + 140°]

arc LR = 48°

Answer: D = 100π square units

Step-by-step explanation:

The formula to calculate the circumference of a circle is C = 2πr, where C is the circumference and r is the radius of the circle.

In this case, we have a circumference of 20π units, so we can set up the equation as follows:

20π = 2πr

To find the radius, we can divide both sides of the equation by 2π:

r = (20π) / (2π)

Simplifying further:

r = 10

Now that we have the radius, we can calculate the area of the circle using the formula A = πr^2:

Consider the differential equation dy de=-0.6(3-4) with y(0)=7. In all parts below, round to 4 decimal places. Part 1 Use n = 4 steps of Euler's Method with h=0.5 to approximate y(2). y(2) Part 2 Use n = 8 steps of Euler's Method with h=0.25 to approximate y(2). y(2) Part 3 Find y(t) using separation of variables and evaluate the exact value. y(2)=L one critic of this theory is that rather than sharing performance gains with workers through bonuses, as taylor had advocated, managers simply increased the amount of work that each worker was expected to do. The health department of Hulu Langat is concerned about youth vaping in the district. At one of the high schools with an enrolment of 300 students, a study found that 51 ofthem were vapers.a)b)c) Calculate the estimate of the true proportion of youth who were vapers in the district. Then construct a 95 percent confidence interval for the populationproportion of youth vapers. Give an interpretation of your result.The health official from the department suspects that the proportion of young vaper in the district is different from 0.12, a figure obtained from a similar nationwide survey. If a test is carried out to check the suspicion of the official, what is the p-value of the test? Is there evidence to support the official's suspicionat the 5% significance level? Is the conclusion consistent with the result in (a)?
