Nonlinear functions SAT question
Math · Advanced Math · Medium · Answer it here, explanation included.
A rubber ball bounces upward one-half the height that it falls each time it hits the ground. If the ball was originally dropped from a distance of 20.0 feet above the ground, what was its maximum height above the ground, in feet, between the third and fourth time it hit the ground?
Enter a number or fraction (like 3/17 or 0.176). Press Enter to check.
ExplanationShow
The correct answer is 2.5. After hitting the ground once, the ball bounces to 
feet. After hitting the ground a second time, the ball bounces to 
feet. After hitting the ground for the third time, the ball bounces to 
feet. Note that 2.5 and 5/2 are examples of ways to enter a correct answer.
