Answer:
is standard equation of hyperbola with vertices at (0, ±9) and foci at (0, ±11).
Step-by-step explanation:
We have given the vertices at (0, ±9) and foci at (0, ±11).
Let (0,±a) = (0,±9) and (0,±c) = (0,±11)
The standard equation of parabola is:
![\frac{y^{2} }{a^{2} } -\frac{x^{2} }{b^{2} }=1](https://tex.z-dn.net/?f=%5Cfrac%7By%5E%7B2%7D%20%7D%7Ba%5E%7B2%7D%20%7D%20-%5Cfrac%7Bx%5E%7B2%7D%20%7D%7Bb%5E%7B2%7D%20%7D%3D1)
From statement, a = 9
c² = a²+b²
(11)² = (9)²+b²
121-81 = b²
40 = b²
Putting the value of a² and b² in standard equation of parabola, we have
which is the answer.
