Distance between foci is 8 and distance between directrices is 6 of hyperbola, then length of latusrectum is

Distance between foci is 4 and distance between directrices is 5

If distance between foci = 3 (distance between directrices) . Then e =

In an ellipse the distance between the foci is 8 and the distance between directrices is 25. then find the length of the major axis.

In an ellipse the distance between the foci is 8 and the distance between the directrices is 25. The length of major axis, is

In an ellipse the distance between the foci is 8 and the distance between the directrices is 25. The length of major axis, is

In an ellipse the distance between the foci is 8 and the distance between the directrices is 25. The length of major axis is : (A) 5sqrt(2) (B) 10sqrt(2) (C) 20sqrt(2) (D) none of these

In an ellipse the distance between the foci is 8 and the distance between the directrices is 25. The length of major axis is : (A) 5sqrt(2) (B) 10sqrt(2) (C) 20sqrt(2) (D) none of these

If distance between the foci of an ellipse is 6 and distance between its directrices is 12, then length of its latus rectum is : (A)4 (B) 3sqrt2 (C)9 (D) 2sqrt2

In an ellipse the distance between the foci is 8 and the distance between the directrices is 25, then the ratio of the length of major and minor axis is
