Atelescope oontains both a parabolic mirror and a hyperbolic mirror. They share focus F1, which is 46 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 2 it below F1. Find the equation of the hyperbole if the center is at the origin of a coordinate system and the foci are on the yaxis. Complete the equation. I t i I l l l:l'l:l=1 l I YY \\ l H H it it ________.__ /
