suppose you drop a tennis ball from a height of 15 feet. After the ball hits the floor, it rebounds to 85% of its previous height. How high will the ball rebound after its third bounce. round to the nearest tenth.. my teacher told be the answers 9.2 but i don't know how she got it
.85*.85*.85 * 15 = .85^3 * 15 = 9.21
