William opens a credit card with an apr of 18.63% compounded monthly. how much is charged in interest this month if his balance is $835?

$12.96

Step-by-step explanation:

I = P  x  (1+r/100)^n - P

P = 835, n=1, r=(18.63/12)% per month

I = 835 x (1+0.015525)^1

    - 835                          

I = $12.96

the answer is b.)

< 1=< 2

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
