A ball is shot from a cannon into the air with an upward velocity of 40ft/sec. The equation that gives the height(h)of the ball at any time(t) is: h(t)=-16t^2 + 40ft +1.5.How long does it take the ball to reach a height of 20 feet?

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

true !
