  1. Question 1

    Q1. The equation of the ellipse with foci on the x-axis and major axis 10 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: 2a = 10, so a = 5. Assuming c = 3 (since c² = a² - b²), b² = 25 - 9 = 16. So, the equation is x²/25 + y²/16 = 1.
