Answer:

37.52 feet

Step-by-step explanation:

Given in the question the equation

h = -16t² + 47t + 3

<em>where h is height in feet </em>

<em>             t is time in minutes</em>

<em />

a = -16

b = 47

c = 3

To find the maximum height of the football

  1. If a, the coefficient of the x² term, is positive, then the parabola opens upward. If a is negative, then the parabola opens downward. In this case it is -16 which is negative so it open downward.
  2. The value of -b/2a tells you the x value of the vertex of the curve at which it is maximum
  3. Plug this value in the equation to find h, maximum height.

t = -b / 2a

 = -47 / 2(-16)

 = 1.47 sec  

h = -16(1.47)² + 47(1.47) + 3

  = 37.52 feet
