What is the average rate of change of h(x) over the interval -13
Ludmilka [50]
The average rate of change of h(x) in the closed interval [ a, b ] is

Here [a, b ] = [ - 2, 2 ], thus
f(b) = f(2) = × 2³ - 2² = 1 - 4 = - 3
f(a) = × (- 2)³ - (- 2)² = - 1 - 4 = - 5
average rate of change = = =

A) Find the area<br>B) Find the perimeter ​
Archy [21]

Answer:

A)

A1= 64

A2= 40

B)

P= 56(of whole shape)

Step-by-step explanation:

A squares area is a side squared so 8^2= 64, and it is also shown that a side of the square is the base of the parallelogram. The area of a parallelogram is b*h so (square side)(8) * height(5)= 40.

Since a parallelograms opposite sides are congruent, 8+8=16, and the other two sides need to be congruent and equal to 40-16(24), therefore the sides are both 12.

Then to calculate the perimeter just count up the side lengths, 8+8+8+12+8+12=56
