A focal chord perpendicular to major axis of the ellipse `9x^(2)+5y^(2)=45` cuts the curve at P and Q then length of PQ is

Length of the major axis of the ellipse 9x^(2)+7y^(2)=63, is

If PSQ is a focal chord of the ellipse 16x^(2)+25y^(2)=400 such that SP=16, then the length SQ is

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

If PSQ is a focal chord of the ellipse 16x^(2)+25y^(2)=400 , such that SP=8, then find the length of SQ.

P is a point on the circle "C: x^(2)+y^(2)=9 " .The perpendicular "PQ" to the major axis of the ellipse "^(E: (x^(2))/(9)+(y^(2))/(4)=1 )" meets the ellipse at M,then (MQ)/(PQ) " is

the length of the latusrectum of the ellipse 5x^(2) + 9x^(2)=45, is
