A ball is passed through the air. the height h of the ball, in feet, after the distance d in feet the ball travels horizontally is giving by the equation h = -2d^2 + 10d + 8. How far horizontally from the player passing the ball with the ball land on the ground? Round to the nearest hundredth if necessary and include appropriate units.​
