Question

an ellipse has a major axis of 12 ft and a minor axis of 5 ft. how far from the center are the foci?

Answer 1

i got 6.5 ft but i'm not sure if that's correct

Answer 2

e=sqrt(1-(5/12)^2))
foci are at ae

Answer 3

i think u got wrong..

Answer 4

e=.091

Answer 5

foci=12*.091=10.91

Answer 6

how did u get that equation?

Answer 7

\[e=\sqrt{1-(b/a)^2}\]

Answer 8

b=5,a=12

Answer 9

idk i tried drawing out the graph... is that an efficient way to work the problem besides using the equation?

Answer 10

foci are at ae distance...these are the basic formulas...

Answer 11

oh... i never learned that in class... uh oh...

Answer 12

thanks!
