On a rainy day, two students begin tracking the accumulated amount of rainfall each hour. They each write a function, R(h), that they think can be used to track the amount of rainfall after h hours. Use the drop-down menus to explain why each function does or does not represent the amount of rainfall after h hours.

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:
