Aball is dropped from a height of 20 feet. after the
first bounce its peak height is 12 feet. with each
bounce, its peak height is 60% of the previous
peak
identify the height of the ball after one, two, and
three bounces
height after one bounce:
feet
height after two bounces
feet
height after three bounces:
feet

1.  

Height after one bounce: ⇒ 12  feet

Height after two bounces:  ⇒ 7.2 feet

Height after three bounces:  ⇒ 4.32 feet

2.

an=a1*r^n-1

3.

⇒ 0.56 feet

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

ratio is 2 : 9

the answer is three

13.5 : 3
