Question

Eccentricity of ellipse `x^2/a^2 + y^2/b^2` = 1, if it passes through point (9, 5) and (12, 4) is ______.

Options

• `sqrt(3/4)`

• `sqrt(4/5)`

• `sqrt(5/6)`

• `sqrt(6/7)`

Answer 1

Eccentricity of ellipse `x^2/a^2 + y^2/b^2` = 1, if it passes through point (9, 5) and (12, 4) is `underlinebb(sqrt(6/7))`

Explanation:

e = `sqrt(1 - 1/7) = sqrt(6/7)`
