Question 1058768
The equation of the model is the equation of a parabola that opens
downward.


The maximum height will correspond to the vertex of the parabola.


The t-coordinate of the vertex is:


t = -b/2a = -40 / (-2*16) = 1.25


Substituting t = 1.25 into the equation gives a height of:


h(1.25) = -16(1.25)^2 + 40(1.25) + 50 = 75 feet


Solution: The maximum height of the object is 75 feet.
