Choose the equation that best represents an ellipse for the given foci and co-vertices.

1. foci (+-2, 0)

co-vertices (0, +-4)

2. foci (+-3, 0)

co-vertices (0,+-6)

3. foci (0, +-3)

co-vertices (+-5, 0)

Choose the equation for the hyperbola centered at the origin with the given characteristics.

8. one focus (0, square root of 34), one vertex (0, 5)

9. vertical transverse axis, b = 6, c = square root of 45

10. vertices (+-2, 0), perimeter of central rectangle 24 units
