Best ResponseYou've already chosen the best response.0Form this ellipse into the general equation. \[\frac{ x^2 }{ a^2 } + \frac{ y^2 }{ b^2 } = 1\]

Best ResponseYou've already chosen the best response.0The ellipse isn't at origin so you need to adjust a little, and use the foci formula \[c^2=a^2b^2\] c = foci

Best ResponseYou've already chosen the best response.0Ok, so..is the general equation x^2/1 + y^2/16= 1?and then use those a and b in the new formula?

Best ResponseYou've already chosen the best response.0The general equation for this ellipse looks like this \[\frac{ (x2)^2 }{ 3^2 } +\frac{ (y2)^2 }{ 2^2 } = 1\]

Best ResponseYou've already chosen the best response.05? That isn't one of my options.. I'm sorry I'm not understanding this. My options are A) (2  sqrt5 , 1) and (2 + sqrt5 , 1) B) (2  sqrt5 , 2) and (2 + sqrt5, 2) C) (2, 1) and (2, 1) D) (3, 1) and (3, 1)
