Choose the correct simplification.
iren [92.7K]

Answer:

x^3y^6z^3 is correct

Step-by-step explanation:

Taking an exponent to the power of an exponent means multiplying the exponents together.

So y^2^3 is the same as y^(2*3) or y^6

Hope that made sense!

Fred earned $22.50 in nine hours. how much did he earn after 4 hours? please show all your work
dusya [7]
I believe the answer is 10

22.50 divided by 9 to show how much for 1 hour. That is 2.5 so next 2.5 x 4 = 10

I don’t completely know if this is correct but I believe it is

14,800 at 6% compounded semiannually for 4 years.. I need to know the interest and the compound amount
Zepler [3.9K]
\bf \qquad \textit{Compound Interest Earned Amount}&#10;\\\\&#10;A=P\left(1+\frac{r}{n}\right)^{nt}&#10;\quad &#10;\begin{cases}&#10;A=\textit{compounded amount}\\&#10;P=&#10;\begin{array}{llll}&#10;\textit{original amount}\\&#10;\textit{deposited}&#10;\end{array}\to &\$14,800\\&#10;r=rate\to 6\%\to \frac{6}{100}\to &0.06\\&#10;n=&#10;\begin{array}{llll}&#10;\textit{times it compounds per year}\\&#10;\textit{semi-annually, meaning twice}&#10;\end{array}\to &2\\&#10;&#10;t=years\to &4&#10;\end{cases}

now, that will give you "A", or the compounded amount

what's the interest earned?  well, subtract the original amount, the Principal, from A, A - P, and you'd be left with the earned interest

--------------------------------------------------------------------------------------------
\bf A=14,800\left(1+\frac{0.06}{2}\right)^{2\cdot  4}
