Question

If the distance from the focus is 10 units and the distance from the directrix is 30 units, then what is the eccentricity? *​

Answer 1

Answer:

0.3333

Explanation:

Explanation: Eccentricity is defined as the ratio of the distance from the focus to the distance from the directrix. Hence from the formula of eccentricity, e = 10 ÷ 30 = 0.3333. Since the value of eccentricity is less than one the conic is an ellipse.
