A Civil War cannon is placed at the base of a hill. The cannon is fired at an angle toward the hill. The path of the cannon ball is parabolic and can be represented by y=-0.04x^2+ 4x + 1, where y
represents the height of the ball in meters and x represents the horizontal distance of the ball
from the cannon. The incline of the hill can be represented by the equation y = 0.8125x. How far
will the cannon ball have moved horizontally from the cannon when it hits the hill?
