Question

A football field is sloped from the center toward the sides for drainage. The height h, in feet, of the field x feetfrom, the side, is given by h=-0. 00025x2 + 0 04x. Find the height of the field a distance of 35 feet from the side The height of the field is □ feet. Round to the nearest tenth as needed.

Answer 1

1.1 feet

Explanation:

h = -0.00025x^2 + 0.04x

Let x be the distance from the side of the field.

x = 35

Put x= 35 into the the equation of h

h = -0.00025(35)^2 + 0.04(35)

h = -0.00025(1225) + 1.4

h = -0.3625 + 1.4

h = 1.0975 feet

h = 1.1 feet (to the nearest tenth)
