1. A , 2.B , 3.D

The standard equation of the ellipse is

[tex]\frac{x^2}{a^2} +\frac{y^2}{b^2} = 1[/tex]

1.We have vertex at (-3,0) and co-vertex at (0,2)

So equation of ellipse is [tex]\frac{x^2}{9} +\frac{y^2}{4} = 1[/tex]

2. We have vertices at (0,6) and (0,-6) and co-vertices at (4,0) and (-4,0)

So equation of ellipse is [tex]\frac{x^2}{16} +\frac{y^2}{36} = 1[/tex]

3. An elliptic track has a major axis that is 80 yards long and a minor axis that is 72 yards long its center is (0,0) and the major axis is the x-axis.

So equation of ellipse is [tex]\frac{x^2}{1600} +\frac{y^2}{1296} = 1[/tex]

Therefore the correct match for the equations are: 1. A , 2.B , 3.D
