Answer:
Part 1)
Part 2)
Step-by-step explanation:
The correct question in the attached figure
Part 1)
we have the formula
where
e the eccentricity
a is the length of the semi-major axis
b is the length of the major axis
solve for a
That means
Isolate the variable a
squared both sides
subtract 1 both sides
Multiply both sides by a^2
Divide both sides by (e^2-1)
Rewrite
square root both sides
simplify
Part 2) we have
Solve for a
substitute in the formula of part 1)
Answer: Lee would make $25 on commission.
Step-by-step explanation: I found this by multiplying 500 by .05 or 5%. Lastly you can check this by taking 25 times 20, because 5% x 20 = 100%, so if 25 was really equal to 5% then it would equal the whole, or 500.
