Question

What is the foci of the ellipse? (x+5)^2/25 + (y-7)^2/144 = 1

Answer 1

Do you know the formula for an ellipse? From that we can get the vertices, and from the vertices the foci.

Answer 2

Yes the vertices are (-5,19) and (-5,-5)

Answer 3

I got (-5,7+-√119) for the foci

Answer 4

okay, that would be most excellent :-)

Answer 5

So that's the foci?

Answer 6

foci is plural for focus, so the grammar isn't quite correct, but the answer is :-)

Haha okay thank you (:
