19.5 yds
Step-by-step explanation:
The equation used to represent the height of the football above the ground after moving a horizontal distance of x yards is expressed as
y = - 0.04x² + 1.56x
The equation is a quadratic equation. The plot of this equation on a graph would give a parabola whose vertex would be equal to the maximum height reached by the football.
The vertex of the parabola is calculated as follows,
Vertex = -b/2a
From the equation,
a = - 0.04
b = 1.56
Vertex = - 1.56/2 × - 0.04 = - 1.56/- 0.08 = 19.5 yards
Therefore, the approximate maximum height of the football is
19.5 yards
