If a ball is dropped from a height of 18 feet, the function f(x) = 18(0.75)* gives the height

in feet of each bounce, where x is the bounce number. What will be the height of the
7th bounce to the nearest tenth of a foot?

Answer:

At the 7th bounce, the ball reached 2.3 feet height.

Explanation:

The given expression is


f(x)=18(0.75)^(x)

This exponential function represents the movement of a bouncing ball after being dropped.


x represents the bounce number.

So, at 7th bounce means
x=7, replacing this value in the function, we have


f(7)=18(0.75)^(7)=18(0.13) \approx 2.34

Therefore, at the 7th bounce, the ball reached 2.3 feet height.
