If s = (a2x2b2y2)what does y equal?

A.

(b2a2)(s2x2)

B.

(b2a2)(s2×2)

C.

x2a2b2s

D.

x2a2b2s

E.

(b2x2)(a2s2x2)

Correct answer is E

s = (a2x2b2y2)

s2 = a2x2b2y2

b2y2 = a2x2 - s2

b2y2 = a2s2x2x2

1y2 = (a2s2x2x2)×1b2

1y2 = a2s2x2b2x2

y^2 = \frac{b^2 x^2}{a^2 - s^2 x^2}

y = \sqrt{\frac{b^2 x^2}{a^2 - s^2 x^2}}
