Atelescope contains both a parabolic mirror and a hyperbolic mirror. they share focus upper f 1, which is 46 feet above the vertex of the parabola. the hyperbola's second focus upper f 2 is 6 ft above the parabola's vertex. the vertex of the hyperbolic mirror is 2 ft below upper f 1. 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.

Ответ:
if the center is at the origin of a coordinate system and the foci are on the y-axis, then the foci are symmetric about the origin.
The hyperbola focus F1 is 46 feet above the vertex of the parabola and the hyperbola focus F2 is 6 ft above the parabola's vertex. Then the distance F1F2 is 46-6=40 ft.
In terms of hyperbola, F1F2=2c, c=20.
The vertex of the hyperba is 2 ft below focus F1, then in terms of hyperbola c-a=2 and a=c-2=18 ft.
Use formula to find b:
.
The branches of hyperbola go in y-direction, so the equation of hyperbola is
.
Substitute a and b:
.
