A sample of an unknown chemical element naturally loses its mass over time. The relationship between the elapsed time t, in days, since the mass of the sample was initially measured, and its mass, M(t)M(t)M(t)M, left parenthesis, t, right parenthesis, in grams, is modeled by the following function:
M(t)=900⋅(827)t
Complete the following sentence about the rate of change of the sample. Round your answer to two decimal places.

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:
