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:
sure where is the attachment?
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
In a function no X's can repeat which is what the vertical line test is. And in this case no X's repeat therefore, making it a function.
the value of f(−23) should be 7/3 from my point of view
Answer: -3 and under
Step-by-step explanation: it can be -2 because it isn't less or equal to and it cant -1 or higher because -1 is bigger than -2 so it can be any thing under -3
like -18 or -190
