A point at which the ellipse `4x^(2)+9y^(2)=72` and the hyperbola `x^(2)-y^(2)=5` cut orthogonally is

Find area of the ellipse 4x ^(2) + 9y ^(2) = 36.

If e and e' are the eccentricities of the ellipse 5x^(2)+9y^(2)=45 and the hyperbola 5x^(2)-4y^(2)=45 then ee' = A.9 B.5 C.4 D.1

If 4x^(2)+ py^(2) =45 and x^(2)-4y^(2) =5 cut orthogonally, then the value of p is

What is the area of the ellipse 4x^(2) + 9y^(2) = 1 .

The ellipse 4x^(2)+9y^(2)=36 and the hyperbola a^(2)x^(2)-y^(2)=4 intersect at right angles.Then the equation of the circle through the points of intersection of two conics is

The foci of the hyperbola 4x^(2)-9y^(2)-1=0 are

The foci of the hyperbola 4x^(2)-9y^(2)-1=0 are

The ellipse 4x^(2) + 9y^(2) = 36 and the hyperbola 4x^(2) – y^(2) = 4 have the same foci and they intersect at right angles then the equation of the circle through the points of intersection of two conics is
