Best ResponseYou've already chosen the best response.0center of \[\frac{(yk)^2}{a^2}\frac{(xh)^2}{b^2}=1\]is \((h,k)\)

Best ResponseYou've already chosen the best response.0in your case it is \((9,4)\)

Best ResponseYou've already chosen the best response.0because the \(y\) part comes first (before the minus sign) this hyperbola looks like this (roughly) dw:1353293873616:dw

Best ResponseYou've already chosen the best response.0to find the vertices, go \(a\) units up up and down from the center. that is why you needed the center first in your case \(a^2=121\) and so \(a=11\)

Best ResponseYou've already chosen the best response.0since the center is \((9,4)\) if you go up 11 units you are at \((9,15)\) and if you go down 11 units you are at \((9,7)\)

Best ResponseYou've already chosen the best response.0hope that is clear, and also that you see it is not that hard once you know what you are doing

Best ResponseYou've already chosen the best response.0I'm still extremely lost, as you can tell math isn't my strong point. I appreciate the help however.
