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

Write the eccentricity of the hyperbola 9x^2-16 y^2=144.

The eccentricity of the hyperbola 9x^(2) -16y^(2) =144 is

Write the eccentricity of the ellipse 9x^2+5y^2-18 x-2y-16=0.

Find the length of the latus rectum of the ellipse 9x^(2)+16y^(2)=144

The coordinates of a focus of the ellipse 4x^(2) + 9y^(2) =1 are

If C is centre of the ellipse x^(2)/a^(2) + y^(2)/b^(2) = 1 and the normal at an end of a latusrectum cuts the major axis in G, then CG =

A point on the ellipse x^(2)/16 + y^(2)/9 = 1 at a distance equal to the mean of lengths of the semi - major and semi-minor axis from the centre, is

The eccentricity of the conic 9x^2-16 y^2=144 is a. 5/4 b. 4/3 c. 4/5 d. sqrt(7)
