I'm sorry the computer jammed on an earlier post and I couldn't do anythingso here is the problem I need asistance with Please check and offer adviceI'm NOT SURE IF I USED CORRECT FORMULASthank you
the problem is List the center, vertices, and foci of hyberbola for following equation:
(y2)^2/36  (x8)^2/64 = 1
b=6
a=8
Center(8,2)
Vertices=(h,k+a) (h,ka)=(h, k+a)=(8,2+6)=(8,8) (8,4)
Foci
This is a verticl hyperbola, correct?
So formula for vertices would be Foci should be c^2 = a^2 + b^2
8^2 + 2^2 = 64+36
c=10
foci=(8,2+10)
(8,8)
(8,12)

looks good to me.
