" In an ellipse "9x^(2)+5y^(2)=45," the distance between the foci is (a) "

In the ellipse 9x^(2)-5y^(2)=45 the distance between the foci is

In the ellipse 9x^(2) + 5y^(2) =45 , the distance between the foci is

In the ellipse 9x^(2) + 5y^(2) = 45 , distance between the foci is

The eccentricity of the ellipse is (2)/(5) and the distance between the foci is 10. Find the length of the latus rectum of the ellipse.

The eccentricity of the ellipse is (2)/(5) and the distance between the foci is 10. Find the length of the latus rectum of the ellipse.

The vertices of an ellipse ar (-1,2) and (9,2) . If the distance between its foci be 8 , find the equation of the ellipse and the eqations of its directrice .

If the eccentricity of an ellipse is (4)/(9) and the distance between its foci is 8 units, then find the length of the latus rectum of the ellipse.

If the eccentricity of an ellipse is (4)/(9) and the distance between its foci is 8 units, then find the length of the latus rectum of the ellipse.

In an ellipse (x^(2))/(a^(2))+(y^(2))/(b^(2))=1 if the distance between the directrix is 3 times the distance between the foci, then the eccentricity is

3x + 4y = 12 sqrt2 is the tangent to the ellipse x^2/a^2 + y^2/9 = 1 then the distance between focii of ellipse is-
