A bridge is built in the shape of a parabolic arch. The bridge arch has a span of 182 feet and a maximum height of 40 feet. Find the height of the arch at 20 feet from its center. Hint: Think of this parabolic arch as a parabola centered at the origin, find its equation and then use x = 20 to find the height y
