hi
lost connection

anonymous · Answer

it's ok np :P could u double-check what i have so far and if i have any wrong could u guide me through 2 see what i did wrong?

anonymous · Answer

center is of course right
vertices are right

anonymous · Answer

major axis is right

anonymous · Answer

not too hard right? since $12^2=144$ and $2\times 12=24$

anonymous · Answer

minor axis is also right as $5^2=25$ adn $2\times 5=10$

anonymous · Answer

yeah :p got that, and minor axis is 10 :P did i get the foci's right tho?

anonymous · Answer

foci we need $c$ 
you get $c^2=144-25=119$ making $c=\sqrt{119}$ whatever that is

anonymous · Answer

k yeah that's 10.908 ~ 10.91

anonymous · Answer

so it will be $(-5,7-\sqrt{119})$ and $(-5+\sqrt{119})$ as the foci

anonymous · Answer

ok typo there

anonymous · Answer

$(-5,7+\sqrt{119})$

anonymous · Answer

(-5, 7 - 10.91) (-5, 7 + 10.91) so the foci's will be:
 (-5, -3.91) and (-5,17.91) right?

anonymous · Answer

you dropped the minus sign in the vertices in your answer above

anonymous · Answer

maybe that was just a typo

anonymous · Answer

yeah, your foci are correct too
