Answer:

A) -15

Step-by-step explanation:

The average rate of change of f(x) on interval [a, b] is given by ...

(f(b) -f(a))/(b -a)

Here, you have ...

f(x) = -2^x +70

[a, b] = [2, 6]

so the average rate of change is ...

(f(6) -f(2))/(6 -2) = ((-2^6 +70) -(-2^2 +70))/4 = (-64 +4)/4 = -16+1

average rate of change = -15

The length of a rectangle is 2 inches more than its width. The perimeter of the rectangle is 24 inches. The equation 2x + 2(x +

alexandr1967 [171]

2x + 2(x + 2) = 24
2x + 2x + 4 = 24
4x = 24 - 4
4x = 20
x = 20/4
x = 5

The value of x that holds true for the equation is : x = 5.
So the width of the rectangle is 5 inches and the length is (x + 2 = 5 + 2) = 7 inches
