Assignment:
Q1. Maximum height. If a baseball is projected upward from ground level with an initial velocity of 64 fcct per second, then its height is a function of time, given by s(t) = - 16t2 + 64t. Graph this function for 0 < t < 4. What is the maximum height reached by the ball'?
Q2. Maximum height. If a soccer ball is kicked straight up with an initial velocity of 32 feet per second, then its height above the earth is a function of time given by s(t) = -16t2 + 32t. Graph this function for 0 < t < 2. What is the maximum height reached by this ball'?'
Q3. Minimum cost. 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 = 0.009x2 - 1.8x + 100. What number of halls per hour should Acme produce to minimize the cost per hour of manufacturing these golf balls?
Q4. Maximum profit. A chain store manager has been told by the main office that daily profit, P, is related to the number of clerks working that day, x, according to the equation P = -25x2 + 300x. What number of clerks will maximize the profit, and what is the maximum possible profit'?
