IF YOU CANT SOLVE THIS YOU'RE RETARDED

Assume that for ?a ? x ? b the surface of the hull is a part of an elliptic paraboloid and for b ? x ? c it is a
part of an ellipsoid, so a + c = 170. Write equations of an elliptic paraboloid with the vertex at
x = ?a and of an ellipsoid with the end point x = c. Since there are many paraboloids and ellipsoids that
satisfy these requirements.
