Answer:

21 h^10

Step-by-step explanation:

(7h^3)(3h^7)

Lets multiply

7*3 h^3 h^7

When the bases are the same , we add the exponents (x^a * x^b) = x ^ (a+b)

21 h^(3+7)

Write a related equation that has the variable on one side. Then simplify the other side.

BartSMP [9]

Because 5 is being subtracted from 1 side, do the opposite and add it to both. 61 plus 5 = 66, so D is correct.

What is the rate of change between the interval of x = 0 and x = pi over two?

bekas [8.4K]

Answer:

The answer is $\frac{4}{\pi }$

Step-by-step explanation:

Given the graph as shown, we have to find the rate of change between the interval of x=0 and $\frac{\pi }{2}$ .

To find the rate of change we have to find the slope which is given by

$Rate\thinspace of \thinspace change=slope=\frac{change\thinspace\thinspace in\thinspace\thinspace y\thinspace\thinspace coordinate}{change\thinspace\thinspace in \thinspace\thinspace x \thinspace\thinspace coordinate}$

= $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

= $\frac{5-3}{\frac{\pi }{2} }$

= $\frac{4}{\pi }$
