Conic Sections

What is the standard form of the equation of a circle with center at (h, k) and radius r?

Which conic section is represented by the equation x^2 - y^2 = 1?

Find the eccentricity of an ellipse with major axis length 10 and minor axis length 8.

The parabola y^2 = 12x has its focus at:

If the equation of a conic is 9x^2 + 16y^2 = 144, what is the length of the major axis?

The equation x^2 + y^2 + 6x - 8y + 9 = 0 represents:

For the hyperbola x^2/25 - y^2/16 = 1, find the coordinates of the foci.

The latus rectum of the parabola y^2 = 8x is:

If the eccentricity of an ellipse is 3/5 and its major axis length is 20, find the length of the minor axis.

The equation of the tangent to the ellipse x^2/9 + y^2/16 = 1 at point (3/2, 2) is:
