A ball is dropped from a certain height. The function below represents the height f(n), in feet, to which the ball bounces at the nth bounce:

f(n) = 9(0.7)n

What does the number 0.7 represent?

Answer 1

the height in feet, right?

Answer 2

0.7 is the portion of the previous height that the ball bounces to

so, the ball starts at 9, and then on the second bounce, it bounces (0.7)*9 feet, and on the third bounce, it bounces to (0.7)*(0.7)*9 feet, and so on...

Answer 3

Answers:
The ball bounces to 30% of its previous height with each bounce.
The height at which the ball bounces at the nth bounce is 0.3 feet.
The ball bounces to 70% of its previous height with each bounce.
The height from which the ball was dropped at the nth bounce is 0.7 feet.
