24.56m. your problem should look like a^2+29^2=38^2. you the. have a^2+841=1444. you subtract 841 from 1444 and are left with 603. < this is a^2. you take the square root of that and get 24.56

Using compound interest, it is found that Dante was 6.6 years old when the balance in the account reached $13,000.

<h3>What is compound interest?</h3>

The amount of money earned, in compound interest, after t years, is given by:

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

In which:

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.

In this problem, we have that the parameters are given as follows:

A(t) = 13000, A(0) = 10000, r = 0.04, n = 12.

Hence the time in years is found as follows:

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

$13000 = 10000\left(1 + \frac{0.04}{12}\right)^{12t}$

$(1.0033)^{12t} = 1.3$

$\log{(1.0033)^{12t}} = \log{1.3}$

$12t\log{1.0033} = \log{1.3}$

$t = \frac{\log{1.3}}{12\log{1.0033}}$

t = 6.6

Four equivalent expressions for 3(6m+3)

TEA [102]

There's an infinite number of equivalent expressions for 3(6m + 3), for example:

3 * 6m + 3 * 3
6 (3m + 1.5)
9 + 18m
1/2 (18 + 36m)

I hope it will help you :)
