The path of a baseball after it has been hit is modeled by the function h = -0.00320 + d + 3, where h is the height in feet of the baseball and d is the distance in feet the baseball is
from home plate. What is the maximum height reached by the baseball? How far is the
baseball from home plate when it reaches its maximum height?

The physical fitness of an athlete is often measured by how much oxygen the athlete takes in (which is recorded in milliliters per kilogram, ml/kg). the mean maximum oxygen uptake for elite athletes has been found to be 60 with a standard deviation of 7.2. assume that the distribution is approximately normal.

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:

What expression is equivalent to (2x-1)(x-3)?
