Let f(x)=−0.5(x−8)2−2 . what is the average rate of change for the quadratic function from x=−4 to x = 8? enter your answer in the box.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

he has now walked a total of what?

if i know what this is maybe i can
