A ball is dropped from the height of 20 feet. the ball rebounds to 80% of his previous height. Let n represent the number of bounces of the ball.
The height of the ball after each bounce can be modeled by
A. H=20(1.80)^n
B. H=20(.80)n
C. H=20(.80)^n
D. H=20(.20)^n

where, for us and in this particular situation, y is the final height, a is the initial height, b is the rate of growth or decline, and x is the number of bounces. We know the initial height is 20, but we need to find the rate of decline. Rewriting the formula to model a rate of decay or decline is
, or more closely related to our circumstances:
and simplifying that a bit:
