Answer:

The characteristics of a good math explanation are following:

1. Step by step explanation: The first characteristics of a good math explanation is step by step solution. Do not skip steps because the assumption that the other person knows what you did is not always correct.

2. Justify each step: Mention the reasons behind each step, i.e, theorem, formula, rule etc.

3. Result verification: After find the solution the last step is to verify the solution.

We need to check whether the solution fulfills the given conditions or not. If it satisfy all the given conditions, then it is correct otherwise we need to check our work.

$650 is invested in an account earning 8.6% interest (APR), compounded monthly. Write a function showing the value of the accoun

IRISSAK [1]

Answer:

The value of the acount after t years is of $A(t) = 650(1.0072)^{12t}$

The annual growth rate is of 0.72%.

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

$A(t) = P(1 + \frac{r}{n})^{nt}$

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

$650 is invested in an account earning 8.6% interest (APR), compounded monthly.

This means that $P = 650, r = 0.086, n = 12$ . So
