Answer:
(a)
- The vertices are at (0,-5) and (0,5).
- The coordinates of the foci are (0,-3) and (0,3).
- Eccentricity=3/5
(b)Length of the major axis=10
Explanation:
When the major axis of an ellipse is parallel to the y-axis.The standard form of the equation of an ellipse is given as:

Given the equation:

(I)The coordinates of the vertices are


Therefore, the vertices are at (0,-5) and (0,5).
(II)The coordinates of the foci are


The coordinates of the foci are (0,-3) and (0,3).
(III)Eccentricity
This is the ratio of the distance c between the center of the ellipse and each focus to the length of the semi major axis.
Simply put, Eccentricity =c/a
Eccentricity=3/5
(b)Length of the major axis
The length of the major axis=2a
=2(5)=10.
