Karen borrowed a sum of money for some big screen TVs and a waterfall for her restaurant. If she borrowed $10,200 and received a 3.85 % interest rate compounded continuously, how much did Karen pay in interest over a 7 year period? Round your answer to the nearest whole number​

3155

Step-by-step explanation:

Continously compounding interest formula:

PV*e^(rt)

10200*e^(.0385*7)=13354.95825

To find the amount of interest paid subtract the original amount

13354.95825-10200=3154.958249

which rounds to

3155

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
