What are the foci of the hyperbola whose equation is (y - 2)^2/64 - (x -4)^2/36 = 1?
(-6, 2) and (14, 2)
(-4, 2) and (12, 2)
(4,-8) and (4, 12)
(4,-6) and (4, 10)

(4,-8) and (4, 12)

Step-by-step explanation:

The equation of the hyperbola given is:

The general form of this hyperbola would be:

Thus, we can see that:

a^2 = 64

a = 8

and

b^2 = 36

b = 6

The distance from one focus to center is called "c", it goes by formula:

Let's find c:

This is a vertical hyperbola and the center is found from the x and y's on the numerator:

(y-2)^2 means y = 2

(x-4)^2 = x = 4

Center is (4, 2)

We go 10 units vertically up, so from y = 2 , ten units up makes it y = 12

x = 4 and y = 12

(4,12)

We go 10 units vertically down, so from y =2, ten units down makes it y = -8

x = 4 and y = -8

(4, -8)

Foci coordinates:

(4,12) and (4,-8)

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars
