If the line $y\, = \,mx\, + \,7\sqrt 3 $ is normal to the hyperbola $\frac{{{x^2}}}{{24}} - \frac{{{y^2}}}{{18}} = 1,$ then a value of $m$ is
$\frac{2}{{\sqrt 5 }}$
$\frac{{\sqrt 5 }}{2}$
$\frac{{\sqrt {15} }}{2}$
$\frac{3}{{\sqrt 5 }}$
The length of the latus rectum of the hyperbola $25x^2 -16y^2 = 400$ is -
The eccentricity of the hyperbola conjugate to ${x^2} - 3{y^2} = 2x + 8$ is
If $5x + 9 = 0$ is the directrix of the hyperbola $16x^2 -9y^2 = 144,$ then its corresponding focus is
Locus of the middle points of the parallel chords with gradient $m$ of the rectangular hyperbola $xy = c^2 $ is
Let tangents drawn from point $C(0,-b)$ to hyperbola $\frac{{{x^2}}}{{{a^2}}} - \frac{{{y^2}}}{{{b^2}}} = 1$ touches hyperbola at points $A$ and $B.$ If $\Delta ABC$ is a right angled triangle, then $\frac{a^2}{b^2}$ is equal to -
