Highway Design In order to build a highway, it is necessary to fill a section of a valley where the grades (slopes) of the sides are 9% and 6% (see figure). The top of the filled region will have the shape of a parabolic arc that is tangent to the two slopes at the points and The horizontal distances from to the -axis and from to the -axis are both 500 feet. (a) Find the coordinates of and (b) Find a quadratic function for that describes the top of the filled region.
