Write the equation for the hyperbola with foci (–12, 6), (6, 6) and vertices (–10, 6), (4, 6).

Step-by-step explanation:

The standard equation of a horizontal hyperbola with center (h,k) is

The given hyperbola has vertices at (–10, 6) and (4, 6).

The length of its major axis is .

The center is the midpoint of the vertices (–10, 6) and (4, 6).

The center is

We need to use the relation to find .

The c-value is the distance from the center (-3,6) to one of the foci (6,6)

We substitute these values into the standard equation of the hyperbola to obtain:

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
