PW as 100
FW as twice PW as 200
answer is 7.27254 years
manually take the log of both sides and solve for n
Answer:
$14.39
Step-by-step explanation:
The formula for continuous compounding of interest is:
A = Pe^(rt), were P is the initial dollar amount, A is the final amount, r is the interest rate as a decimal fraction, and t is the time in years.
Here we have $2109 = $500e^(10r) and need to solve for r.
To do this, take the natural log of both sides, obtaining:
ln 2109 = ln 500+ 10r.
Then 10r = ln 2109 - ln 500, and
ln 2109 - ln 500
r = --------------------------------------------
10
= .1439
The interest rate was 14.39%.

By definition, the equation of a circle, centered at point (a, b) is

Where r is the radius of the circumference, and is calculated as the distance from the center to any point belonging to the circumference.
We have the center (5, -4) and the point through which the circumference passes (-3, 2), then:

Finally, the equation of the circumference is:
