A superball is bounced from a height of 20 feet. The function f(x) = 20(0.9)x gives the height of the ball in feet after each bounce, where x is the bounce number. What will be the height of the 6th bounce? Round your answer to the nearest tenth (one decimal point).

feet

What will be the height of the 9th bounce? Round your answer to the nearest tenth (one decimal point).

feet

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

final total: 63
