PLEASE HELP ASAP!!!!!
I need to figure out the equation(s) for a circle that's 6 up and down and 5 left and right. It's on a graph. The main equation he gave me was 18x^2 + 36y^2 = 648 and he said the foci was +or- 3 sqrt 2, 0. Help!!!!!!!!!!!

Answer 8

im trying to figure out what he means

Answer 9

If you graphed this, the y-intercepts would be 6 and -6, while the x-intercepts would be 5 and -5. What I don't understand is how to make equations out of that. It deals with foci and asymptotes and stuff like that but that's all I know.

Answer 10

so like this

Answer 11

right

Answer 12

but I don't know how to get an equation out of it

Answer 13

Identify the major and minor axes first. Where is the center?

Answer 14

at 0,0 right?

Answer 15

yes

Answer 16

ok, so now what do I do?

Answer 17

@tylermcmullen23 @luffingsails

Answer 18

so wait, the foci was EITHER positive or negative 3?

Answer 19

ummm yeah I think so he wrote down on the paper + or - 3 sqrt 2

Answer 21

@tylermcmullen23 how would you take the equation 18x^2 + 36y^2 = 648 and the foci + or - 3 sqrt 2 and make the shape of a face out of it?

Answer 22

HELP!!!!!!!!!!!!!!

Answer 23

your supposed to make the shape of a face out of it??

Answer 24
