Explanation:
The equation of comet E is given below as

The equation of comet H is modelled below as

Given, that the Sun is located at the origin.
This is an equation of an ellipse. So, the path traveled by Comet e is an elliptic path.
Comparing with the Standard equation of ellipse: below,we will have

Whise center is

By comparing coefficient, we will have

Hence,
The vertex of comet E will be

The vertex of comet E is

Part C:
It is the foci forboth comets

Hence,
The foci will be
10(4^2-(9)
Since 16-9 is 7
And 10 times 7 is 70

ANSWER
D. x=55
EXPLANATION
The given radical equation is

Add -3 to both sides


Square both sides.


Solve for x to get:

Answer:
B. They are perpendicular
Step-by-step explanation:
calculate the gradient of (-6, -1) and (-11, 1)
m= y2 - y1/ x2 - x1
= 1 - (-1)/ -11 -(-6)
m = <u>-</u><u>2</u><u>/</u><u>5</u>
then you find the gradient of the other points in the same way
m = y2 - y 1/ x2 -x1
= -13 -(-8)/ -5 -(-3)
m = 5/2
to prove that they are perpendicular
m1×m2 = -1
-2/5 × 5/2 = <u>-</u><u> </u>1
hence they are perpendicular
