A telescope contains both a parabolic mirror and a hyperbolic mirror. They share focus F1, which is 44 feet
above the vertex of the parabola. The hyperbola's second focus F2 is 8 ft above the parabola's vertex. The
vertex of the hyperbolic mirror is 4 ft below F. Find the equation of the hyperbola if the center is at the origin
of a coordinate system and the foci are on the y-axis.
