What is the center of the hyperbola whose equation is (y+3)^2/81-(x-6)^2/89=1?
A. (-6, 3)
B. (-3, 6)
C. (3, -6)
D. (6, -3)

We have been given an equation of hyperbola . We are asked to find the center of hyperbola.  

We know that standard equation of a vertical hyperbola is in form , where point (h,k) represents center of hyperbola.

Upon comparing our given equation with standard vertical hyperbola, we can see that the value of h is 6.

To find the value of k, we need to rewrite our equation as:

Now we can see that value of k is . Therefore, the vertex of given hyperbola will be at point and option D is the correct choice.
