An account earns simple interest. $5200 at 7.36% for 54 months. find the interest earned. find the balance of the account

Interest earned=$ 1722.24

New Balance of account=$6922.24

Step-by-step explanation:

An account earns simple interest.

$5200 at 7.36% for 54 months.

The principal account (P) =$5200

R=7.36%

T=54 months=54/12 year=4.5 year.

Hence, simple interest(I) is calculated as:

Hence, interest earned=$ 1722.24

Hence, the new balance of the account is:

P+I

=5200+1722.24

=$ 6922.24.

Hence new balance of account=$ 6922.24

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

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
