C is the centre of the ellipse (x^(2))/(25)+(y^(2))/(16)=1 and S is one of the foci.The ratio of CS to semi major axis is

C is the centre of the ellipse (x^(2))/(25)+(y^(2))/(16)=1 and S is one of the foci. The ratio of C S to semi major axis is

If C is the center of the ellipse 9x^(2)+16y^(2)=144 and S is a focus,then find the ratio of CS to the semi-major axis.

If C is the centre of the ellipse 9x^(2) + 16y^(2) = 144 and S is one focus. The ratio of CS to major axis, is

If C is the centre of the ellipse 9x^(2) + 16y^(2) = 144 and S is one focus. The ratio of CS to major axis, is

If C is the center of the ellipse 9x^2+16 y^2=144 and S is a focus, then find the ratio of C S to the semi-major axis.

If C is the center of the ellipse 9x^2+16 y^2=144 and S is a focus, then find the ratio of C S to the semi-major axis.

The equation of the parabola whose vertex is at the centre of the ellipse x^2/25+y^2/16 = 1 and the focus coincide with the focus of the ellipse on the positive side of the major axis of the ellipse is

Circles are described on the major axis and on the line joining the foci of an ellipse (x^(2))/(25)+(y^(2))/(16)=1 as diameters. The radii of the circles are in the ratio
