Question 1185963: Write an equation for the ellipse with each set of characteristics. Then answer the question. Vertices (-7,-3), (13-,3) foci (-5,-3),(11,-3)
What is the a and b value of the ellipse?
Answer by greenestamps(13200) (Show Source): You can put this solution on YOUR website!
The major axis is horizontal; the center of the ellipse is halfway between the vertices (or halfway between the foci), at (3,-3). The equation is
a is the distance from the center to each vertex = 10
c is the distance from the center to each vertex = 8
c^2=a^2-b^2 --> b=6
ANSWERS:
a=10; b=6
The equation is
