If a basketball is bounced from a height of 20 feet, the function f(x)= 20 (0.9)^x gives the height of the ball in feet of each bounce number. What will be the height of the 6th bounce? Round your answer to the nearest tenth of a foot

Respuesta :

Answer:

10.6 feet to the nearest tenth.

Step-by-step explanation:

The first bounce will rise to the height 20(0.9)^1   ( putting x = 1).

= 18 feet.

So the height of the 6th bounce will be

20(0.9)^6

= 10.6 feet.
