I need this as soon as possible (preferably August 24). Thank you.
1. If a baseball is projected upward from ground level with an
initial velocity of 64 feet per second, then its height is a function
of time, given by: s(t) = -16t^2 + 64t. Graph this function for 0 <
or equal to t < or equal to 4. What is the maximum height reached by
the ball?
2. It costs Acme Manufacturing C dollars per hour to operate its golf
ball division. An analyst has determined that C is related to the
number of golf balls produced per hour, x, by the equation C =
0.009x^2 ? 1.8x + 100. What number of balls per hour should Acme
produce to minimize the cost per hour of manufacturing these golf
balls?
