Answer 1

@Johnbc could you help a lil? u seemed to know what u were doing yesterday

Answer 2

@jim_thompson5910 here are some more i have no idea how to do them

Answer 3

hey john do you have an idea on how to solve this?

Answer 4

@kales9616 come here and hlp plz

Answer 5

For the first image we can see that the hyperbola is with a vertical transverse axis so the general equation for that would kind of hyperbola would be:\[\frac{ (y-k)^2 }{ b^2 }-\frac{ (x-h)^2 }{ a^2 }= 1\] where the (h,k) represent the center of the hyperbola

Answer 6

automatically we can see that the the center for the x axis (h) is -4 and that the middle is 7 so if we plug that in for h and k we get

Answer 7

\[\frac{ (y-7)^2 }{ b^2 }-\frac{ (x-(-4))^2 }{ a^2 }\]

Answer 8

so the -4 turns into positive 4 and we have the top of our equation as for the bottom i am unsure of how to solve for the asymptote of this hyperbola so you will need a second opinion

Answer 9

what is b^2?

Answer 10

it will be an asymptote which i do not recall how to find

Answer 11

oh.... ok well ty for ur hellp on that one, do you know how to solve the other one?
