Question

suppose you drop a tennis ball from a height of 15 feet. After the ball hits the floor, it rebounds 85% of its previous height. How high will the ball rebound after its third bounce? Round to the nearest tenth.

Answer 1

Height is 15 feet

It rebounds 85% of its original height

.85*15=12.75 feet on 1st bounce

12.75*.85=10.8375 feet on the 2nd bounce

10.8375*.85=9.211875 feet on 3rd bounce

So your answer is 9.2 feet high

Hope this helps!
