Best ResponseYou've already chosen the best response.0The foic lie on the line called the major. This ellipse major is on the x axis. The equation of this ellipse is \( \huge \frac{x^2}{36} +\frac{y^2}{4} = 1 \) The foci is (c, 0) and (c,0) \( \huge c= \sqrt{364} \) Can you tell us what c equals?

Best ResponseYou've already chosen the best response.0If you are wondering where I got 36, I got it from starting at (0,0) and counting to my right to the end where the circle meets the x axis, which is 6. Then I \( 6^2 = 36 \)
