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
Step-by-step 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.
We know that both lines will be equivalent, so to solve for x we can equate the two expressions
5x = 2x + 63
We will first subtract 2x from both sides
3x = 63
We will then divide both sides by 3
x = 21
Answer:
73.81
Step-by-step explanation:
You know that the formula for circumeference is 2(pi)r.
2x3.14x11=69.08;
However, a part of the circle is cut off, leaving 3/4 of it.
3/4x69.08=51.81.
However, you add the 11+11 to it because of the slice.
22+51.81=73.81
1.5 is the correct answer :)
