Identify the constant difference for a hyperbola with foci (-8, 0) and (8, 0) and a point on the hyperbola (8, 30)

Answer 1

(-8,0) (8,0) as foci point (8,30) on the hyperbola

distance from (8,0) to (8,30) is 30

distance from (-8,0) to (8,30) is d = sqr(30^2+ 16^2) = sqr(900+256) = sqr(1156) = 34

34-30 = 4 = constant difference in distances to each focus from a point on the hyperbola
