Charles johnson deposited $4,400 in a savings account earning 6% interest compounded quarterly. if he makes no other deposits or withdrawals, how much will his money earn in two years?

he will earn $4956.6 in two years

Step-by-step explanation:

Initial amount deposited by Charles Johnson into the account is $4,400

This means that the principal is P

P = 4400

It was compounded quarterly. This means that it was compounded once in four months. Therefore,

n = 4

The rate at which the principal was compounded is 6%. So

r = 6/100 =0.06

It was compounded for a total of 2 years. Therefore

t = 2

The formula for compound interest is

A = P(1+r/n)^nt

A = total amount in the account at the end of n years.

A = 4400(1+0.06/4)^4×2

A = 4400(1+0.015)^8

A = 4400(1.015)^8

A = $4956.6

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.
