What is the center?

OpenStudy (helder_edwin):

can u get the center?

OpenStudy (anonymous):

Not sure how?

OpenStudy (mertsj):

\[\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1\]

OpenStudy (mertsj):

(h,k) is the center.

OpenStudy (anonymous):

so to I add the center? OR..

OpenStudy (helder_edwin):

the center is (-10,5). agree?

OpenStudy (anonymous):

Yes

OpenStudy (helder_edwin):

the major axis a=10 and the minor axis b=8, agree?

OpenStudy (anonymous):

Yes!

OpenStudy (helder_edwin):

can u compute c? c is the distacne from the center to either focus

OpenStudy (helder_edwin):

there is a relation (an equation) between a, b, and c. do u know it?

OpenStudy (helder_edwin):

ok the relation is \[\large a^2=b^2+c^2 \] then the coordinates of the foci are \[\large (h,k\pm c) \] because the ellipse is vertical
