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:
Area of circle is calculated by:
A = pi x radius^2 = pi x 14^2 = 615.75 (m2)

Answer:
4000
Step-by-step explanation:
THe formula given is:
T = UN + F
Where T is the total cost
U is the cost per unit
N is the number of units manufactured
F is the fixed cost
Also, in the problem, it is given,
F = 5000
U = 15
T = 65000
We need to find N, the number of clocks, so lets rearrange the formula so that we have N = SOMETHING:
Now we substitute the given information into this to find N:
So,
number of clocks made = 4000
