An arch is in the shape of a parabola. It has a span of 220 meters and a maximum height of 22 meters.
Find the equation of the parabola (assuming the origin is halfway between the arch's feet).
Determine the height of the arch 30 meters from the center.
Be sure your variables match those in the question `x^2=-550 (y-22)`
