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:

Hi there!
So let's see, we have a die and need to know the probability of rolling a number less than or equal to 4. Let's list the numbers that are less than or equal to 4: 1, 2, 3, 4. Now, since we know that there are 6 numbers on a die and 4 of them are less than or equal to 4, we can set up a fraction to find the percentage. The fraction would be 4/6 because 4 out of the 6 numbers on the die are less than or equal to 6. We can simplify 4/6 to 2/3 as well. To find the percentage, all we need to do is divide the numerator by the denominator. This leaves us with approximately 66.66%.
Hope this helps!! :)

Answer:
$413.83
Step-by-step explanation:
Your earnings for the two weeks are
7.25(40)(2) = 580
The deductions for FICA will be
0.0765(580) = 44.37
The deductions for federal withholding will be
0.14(580) = 81.2
The deductions for state withholding will be
0.07(580) = 40.6
This makes your realized income
580-(44.37+81.2+40.6) = 580-166.17 = 413.83
