Q.	If the distance from the directrix is 5 units and the distance from the focus is 3 units then what is the name of the conic section?
A.	ellipse
B.	parabola
C.	hyperbola
D.	circle
Answer» A. ellipse
Explanation: eccentricity is defined as the ratio of the distance from the focus to the distance from the directrix and it is denoted by e. hence, by definition, e = 3 ÷ 5 = 0.6. hence the conic section is called an ellipse.
