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.
