Best ResponseYou've already chosen the best response.0i hyperbola has the equation \(\Large \frac{x^2}{a^2}\frac{y^2}{b^2}=1\) so you need to find a and b

Best ResponseYou've already chosen the best response.0okay thank you! so the first problem is \[\frac{ x ^{2} }{ 3^{2} }\frac{ y ^{2} }{ 4^{2} }=1\]

Best ResponseYou've already chosen the best response.0to find the foci you need to find a and b again then use b^2+c^2=a^2 c=sqrt{a^2b^2} c is the distance from the foci to the center of that rectangle

Best ResponseYou've already chosen the best response.0that will get you the coordinates of the foci

Best ResponseYou've already chosen the best response.0well i said c is the distance from center to foci so what do you think any idea

Best ResponseYou've already chosen the best response.0actually an error \(c=\sqrt{a^2+b^2}=\sqrt{29}\) the foci has coordinates (0,c)
