Question

What is the eccentricity of the ellipse:
(x+7)^2/16 + (y-3)^2/4=1

A. 2/√3

B. √3/2

C. √3/4

D. √3

Answer 1

I got B. Is that correct?

Answer 2

@ranga is my answer right?

Answer 3

hmm what did you get for the component "c"?

Answer 4

e = c /a
first find what c is.
a^2 = 16
b^2 = 4
a^2 + b^2 = c^2

Answer 5

that is, the distance from the vertex to either focus

Answer 6

yes. I believe so.

Answer 7

I think i got the formula wrong lol

Answer 8

Well a = √16 = 4, b = √4 = 2 . eccentricity = √[1 - (b/a)²] = √[1 - (2/4)²] = (√3)/2 .

Answer 9

yep.

Answer 10

no the formula is e=c/a shamil :)

Answer 11

thanks! :)

Answer 12

yw.

Answer 13

ohh .. I misread you, I thought you said, c, yes it's B

Answer 14

thanks!!
