vertex at (–3, 0) and co-vertex at (0, 2)

Answer 1

@dovakiin

Answer 2

I'm actually doing a whole assigment so yeah :( need some help..

Answer 3

you have a =+-3, b= =-2 just apply the formula \[\frac{ x^2 }{ a^2 }+\frac{ y^2 }{ b^2 }=1\]

Answer 4

what 's else?

Answer 5

Oh okay.

What are the foci of the ellipse? Graph the ellipse.

Answer 6

x^2/49+y^2/64=1

Answer 7

you have a formula for this, too. foci c ^2 = a^2-b^2

Answer 8

hey, a= 3--> a^2 =9, not 49

Answer 9

b=2 -->b^2 =4 only

Answer 10

okay

Answer 11

c^2 = 9 -4 =5 ---> c = =-sqr (5) no way to have the integer. just estimate between 2 and 3 on the x-axis

Answer 12

gotcha ok i understand noww
