SOLUTION: (x+6)^2_______(y-4)^2 ----------- -- + ----------- ---- = 1 ___12__________ 16 this is a ellipse formula. find the vertices and foci coordintes. (the dash marks are fraction

SOLUTION: (x+6)^2_____(y-4)^2 ----------- -- + ----------- ---- = 1 _12__________ 16 this is a ellipse formula. find the vertices and foci coordintes. (the dash marks are fraction

Question 454238: (x+6)^2_______(y-4)^2
-------------- + ---------------- = 1
___12__________ 16
this is a ellipse formula. find the vertices and foci coordintes.
(the dash marks are fractions, the underscores are nothing, it wouldnt let me format it properly.
THANKS FOR TRYING!

Use braces { and }, 3 on each end, to format.
Long axis is "vertical", parallel to the y-axis (16>12)
Center at (-6,4)
Distance from center to foci = sqrt(16 - 12) = 2
Foci at (-6,2) and (-6,6)
-----------------------
Vertices at center +/- sqrt(16) vertically --> (-6,0) & (-6,8)
Vertices at center +/- sqrt(12) horizontally
--> (-6-sqrt(12),4) & (-6+sqrt(12),4)
