Write an equation for the hyperbola that satisfies the given set of conditions. Vertices (21, 0) and (-21, 0), conjugate axis of length 10 units.

May 6th, 2015

(x-h)^2/a^2-(y-k)^2/b^2 = 1

the center of hyperbola is (0, 0)

h=0 and k=0

42=2a

a=21

a^2=441

from given conjugate axis 10=2b, b=5, b^2=25

answer:

equation of hyperbola x^2/441-y^2/25=1
