Question

Find the standard form or the equation of the ellipse w/ vertices: (+-7,0) and eccentricity e=2/7

Answer 1

id have to look up what eccentricity is lol

Answer 2

x^2 y^2
--- + ---
49 b^2 is all i got without that bit of info

Answer 3

eccentricity = foci point/ vertex

Answer 4

ok that's helpful to know lol

Answer 5

so the foci are at 2; and the vertex = 7 soo

b^2 = 49 + 2^2

Answer 6

wait wouldn't it be -

Answer 7

sqrt(53) = b^2

so 53 should be tucked under the y right? which seems odd to me

Answer 8

-2^2 yeaah, your right lol

Answer 9

that dont seem so wierd to me now lol

Answer 10

45 under the y is better lol

Answer 11

wew ok I was thinking the same thing thanks so much I'm starting to get the hang of this silly math nonsense lol
