The balance in a savings account at the end of each year is shown below. The year is denoted by n, and the account balance is
vovangra [49]

Answer:

A(n) = 100(1.1)^n

Step-by-step explanation:

Given that :

Account balance = A(n)

Compound interest paid = 10%

We need to obtain the initial amount deposited, that is A(n), when n = 0

In year, n = 1

Account balance, A(n) = $110

Let initial deposit = P

Hence,

Compound interest relation should be ;

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

Plugging in our values

110 = P(1 + 0.1)^1

110 / P = 1.1^1

110/P = 1.1

110 = 1.1P

P = 110 / 1.1

P = 100

Hence, we can define the amount paid inn n years by substuting the value of P into the compound interest formula :

A(n) = 100(1 + 0.1)^n

A(n) = 100(1.1)^n

What is the rate of change (86, 124) (64, 113)
harkovskaia [24]
Hey there!

The rate of change for these two points would be m = 1/2. Subtract the two y points from each other and then the two x points from each other. Then you divide them. Or get a simplified fraction.

Hope this helped!
