You know the standard equation right?

anonymous · Answer

x^2/a^2+y^2/b^2=1 ?

anonymous · Answer

@Luigi0210

luigi0210 · Answer

Sorry, give me some time to try and remember this

anonymous · Answer

no problem :)

luigi0210 · Answer

I'm guessing it'd be c..

anonymous · Answer

how'd u get that??

luigi0210 · Answer

because they're saying that radius of the moon is 567, and that the surface from both sides are 900 and 169, so i added them together to get the full radius of the ellipse.

luigi0210 · Answer

And the longer side is on the y-axis so y should have the larger value.

Am I right?

anonymous · Answer

yeah since it's larger! I mean that reasoning makes sense to me, usually I can do this type, but the word problem and picture threw me off a bit lol! thank you :)

luigi0210 · Answer

You're welcome :)

anonymous · Answer

hey @Luigi0210 do you anything about vertical asymptotes by any chance?

luigi0210 · Answer

Do you mean like in a problem?

anonymous · Answer

yeah well I think I solved a problem correctly but I just want to double check with someone who knows Lol!

luigi0210 · Answer

Yea I got a pretty good idea on it.

anonymous · Answer

okay so in the question I have to find the vertical asymptotes of $$\lim_{x \rightarrow 5-} x/x-5$$ I got that as oo,5

anonymous · Answer

well I have to find the limit and vertical asymptotes but the limit is already given as -5

luigi0210 · Answer

The vertical asymptote is 5

anonymous · Answer

Yay so I got it right sort of. LOl

luigi0210 · Answer

Just remember, you get it by setting the denominator equal to zero and solving.
The limit should be -infinity, or DNE if you don't accept infinity as an answer yet.

anonymous · Answer

ahh okay so -oo not oo thank you :)

Yup, as you see the graph is going down on the left.
