A hyperbola has vertices (±5, 0) and one focus (6, 0). What is the standard-form equation of the hyperbola?..

To find the standard form equation of the hyperbola, we can use the formula for the distance between the center of the hyperbola and the vertices:

c^2 = a^2 + b^2

where a is the distance between the center and a vertex, b is the distance between the center and the foci, and c is the distance between the center and a focus.

In this case, the distance between the center and the vertices is a = 5, the distance between the center and the focus is c = 6, and the distance between the center and the co-vertex is b.

Since the distance between the center and the focus is c = 6, we have:

c^2 = a^2 + b^2
6^2 = 5^2 + b^2
36 = 25 + b^2
b^2 = 11

Now that we have a, b, and c, we can write the standard form equation of the hyperbola:

(x-h)^2/a^2 - (y-k)^2/b^2 = 1

where (h, k) is the center of the hyperbola.

Since the hyperbola is centered at (0, 0), the equation becomes:

x^2/25 - y^2/11 = 1

Therefore, the standard form equation of the hyperbola is:

x^2/25 - y^2/11 = 1.
