Question

What are the foci of the following graph?

Answer 1

@Hero

Answer 2

What are the vertices?

Answer 3

3 and -3?

Answer 4

that are co-vertex, how about main one?

Answer 5

5 and -5

Answer 6

i ment 6 and -6

Answer 7

ok, it is a vertical ellipse, hence the main one is a, and the co- one is b
that is a = 6 and b =3
you have the formula to find foci c, which is \(c^2 = a^2 -b^2\), hence c =??

Answer 8

27?

Answer 9

that is c^2 , not c

Answer 10

13.5?

Answer 11

\(\sqrt{27} =??\)

Answer 12

5.19615

Answer 13

ok, it is \(3\sqrt3\)
you can take your number.

Answer 14

One more thing, foci are on the same line with main vertices, right? your main one is \((0, \pm 6)\), hence your foci are \((0,\pm 3\sqrt3)\)
Whenever jot down the foci or the vertex, you MUST write the pair of them to make it clear for the shape of the conic.

Answer 15

so what the anwser? im sorry..this confuesses me
