The distance traveled by a student walking at a constant rate varies directly with the amount of time the student walks. the student walked 1 2/3 miles in 2/3
hour. which of the following represents the relationship between d, the distance in miles walked by the student, and t, the amount of time in hours the student walked?
d=5/2t, d=7/3t, d=10/9t, d=2/5t

Suppose that x and y are both differentiable functions of t and are related by the given equation. use implicit differentiation with respect to t to determine startfraction dy over dt endfraction in terms of x, y, and startfraction dx over dt endfraction .

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:

If you answer 2+2 you will get over 80 points
