Consider the attached ellipse. Let the sun be at the right focus. Then perihelion is at right vertex on the x-axis and aphelion is at the left vertex on the x-axis.
The distances:
- from perihelion to the sun in terms of ellipse is a-c;
- from aphelion to the sun in terms of ellipse is a+c.
Then

Add these two equations:
and subtract first equation from the second:
Note that
thus

The equation for the planet's orbit is

Answer:
False
Step-by-step explanation:
6/12 simplifies into 1/2 (six is half of twelve) and 1/2 does not equal 1/3.
You can also plug this into a calculator and see that 6/12=0.5 and 1/3=0.333
Answer:23
Step-by-step explanation:
add 5 and 4 then subtract it from 32
Answer:
8
Step-by-step explanation:
A co-efficent is a number used to multiply a variable, and since 8x is the only variable, that means 8 is the only co-efficent.
(hope this helps :P)
