Question

The equation of a parabola is shown.
y = 1/12 x^2
What are the coordinates of the focus?

Answer 1

what kind of math is this?

Answer 2

algebra 2 and the choices are (0,2.5) (0,-2.5) (0,0.8) (0,0.4)

Answer 3

is it in the form of \[x ^{2}= 4ay\]

Answer 4

yes

Answer 5

then transpose 1/12 towards LHS and AS HERE THE EQUATION becomes \[x ^{2}=12y; x ^{2}= 4\times3y \] so here a is 3 so the co-ordinates are (0,3)....got it?

Answer 6

yup! THANK YOU SO MUCH

Answer 7

No problem.... @megymegy My pleasure

Answer 8

WAIT so would in the answer choices o,3 isn't in there would I just put 0, 2.5?
