Help will fan and medal.

Find the constant difference for a hyperbola with foci at F1 (0, -17) and F2 (0, 17), and point on the hyperbola (0, -15).

A.20
B.30
C.40
D.10

Answer 1

"The hyperbola definition in geometry is the locus of points satisfying the condition that the difference of distances from two point’s foci is always constant."

Since (0,-15) is a point on the hyperbola, its distance from F1 (0,-17) is 2 and from F2 (0,17) is 32. The difference of distances should be..... :)

Answer 2

so the answer is 30

Answer 3

Yup u got it :)

Answer 4

Thanks for explaining. (:
