Multiply each term by a^2b^2:-
b^2y^2 + a^2x^2 = a^2b^2
subtract a^2x^2 from both sides
b^2y^2 = a^2b^2 - a^2x^2
Now divide both sides by b^2
y^2 = a^2 - a^2x^2 / b^2 = a^2 (1 - x^2/b^2)
take positive square root ( because y > 0)
y = a sqrt(1 - x^2/b^2)
The answer is D because that is the closest answerr to 40
Kite Area = (diagonal1 * diagonal2) / 2
Kite Area = (30 * 4) / 2
Kite Area = 60 square feet
(x - 8)² + (y - 6)² = 5²
(x - 8)² + (y - 6)² = 25 ← answer
