need help again?

jim_thompson5910 · Answer

did you look at that previous link I sent?

anonymous · Answer

yes

jim_thompson5910 · Answer

did it make sense?

anonymous · Answer

yes

jim_thompson5910 · Answer

so how far did you get with this?

anonymous · Answer

i know b^2 = 4
k= 1
horizontal orientation

jim_thompson5910 · Answer

what's h?

anonymous · Answer

want h= ?
  and a = ?

anonymous · Answer

i dont know

jim_thompson5910 · Answer

to find h, add up the x coordinates of the vertices, then divide by 2

anonymous · Answer

why? whats the logic?

jim_thompson5910 · Answer

(h,k) is the center of the hyperbola

the center is always at the midpoint of the segment AB

A is one vertex
B is the other vertex

the drawing is somewhat bad, but you get the idea
