  1. Question 1

    Q1. The equation of the ellipse with foci (±3, 0) and vertices (±5, 0) is

    • A) x²/25 + y²/16 = 1
    • B) x²/16 + y²/25 = 1
    • C) x²/25 + y²/9 = 1
    • D) x²/9 + y²/25 = 1

    Answer: x²/25 + y²/16 = 1

    Explanation: Here a = 5, c = 3, b² = a² - c² = 25 - 9 = 16, so the equation is x²/25 + y²/16 = 1.
