Hey there! :)

Answer:

x = 12.

Step-by-step explanation:

Set the two proportions equal to each other:

$\frac{5}{x} = \frac{30}{72}$

Cross multiply to solve for x:

5 · 72 = 30 · x

360 = 30x

Divide both sides by 30:

360/30 = 30x/30

12 = x.

Therefore, the value of 'x' in this proportion is 12.

H(x)=

UNO [17]

The average rate of change of the function over −2 ≤ x ≤ 2 is 1/2

<h3>How to determine the average rate of change?</h3>

The function is given as:

$h(x) = \frac 18x^3 - x^2$

The interval is given as:

−2 ≤ x ≤ 2

Calculate h(2) and h(-2)

$h(2) = \frac 18 * 2^3 - (2)^2$

h(2) = -3

$h(-2) = \frac 18 * (-2)^3 - (-2)^2$

h(-2) = -5

The average rate of change is then calculated as:

$m = \frac{h(-2) - h(2)}{-2-2}$

This gives

$m = \frac{-5 + 3}{-4}$

Evaluate

m = 1/2

Hence, the average rate of change of the function over −2 ≤ x ≤ 2 is 1/2

1.7cubic feet per minutes Given that one cubic foot is equivalent to approximately 7.48 gallons what would the pump rating be in

son4ous [18]

Answer:

449 per hour

Step-by-step explanation:

First of all we know the question is asking us to round to the nearest tenth and find the rate of gallons per hour.

First:

Know there are 60 minutes in one hour

Second:

Take 7.48 and multiply it by 60

Third:

This should give you---448.8

Which is correct, but we are not done

Fourth:

Round to the nearest whole number

448.8

8 is closer to 10 than it is to 1 so we add 0.2

Which gives us 449

Five:

Just add the "per hour"

Six:

Your answer is---449 per hour---
