The eccentricity of the curve $x^2 - y^2 = 1$ is

The foci of the hyperbola $9x^2 - 16y^2 = 144$ are

The equation of the hyperbola whose conjugate axis is $5$ and the distance between the foci is $13$,is

Let the foci of the hyperbola coincide with the foci of the ellipse $\frac{x^{2}}{36}+\frac{y^{2}}{16}=1$. If the eccentricity of the hyperbola is $5$, then the length of its latus rectum is:

The equation $x^2 - 4y^2 - 2x + 16y - 40 = 0$ represents:

The eccentricity $e$ of a hyperbola can never be equal to which of the following values?
