Please please please help. I will give you a medal! A tunnel is in the shape of a parabola. The maximum height is 50 m and it is 10 m wide at the base as shown below. A parabola opening down with vertex at the origin is graphed on the coordinate plane.
The height of the parabola from top to bottom is 50 meters and its width from left to right is 10 meters.
What is the vertical clearance 2 m from the edge of the tunnel?
