You invest $7000 in an account bearing 5% for ten years. How much will the account be worth if compounded quarterly? What about
Mars2501 [29]
\bf \qquad \textit{Compound Interest Earned Amount}&#10;\\\\&#10;A=P\left(1+\frac{r}{n}\right)^{nt}&#10;\qquad &#10;\begin{cases}&#10;A=\textit{current amount}\\&#10;P=\textit{original amount deposited}\to &\$7000\\&#10;r=rate\to 5\%\to \frac{5}{100}\to &0.05\\&#10;n=&#10;\begin{array}{llll}&#10;\textit{times it compounds per year}\\&#10;\textit{quarterly, means 4 times}&#10;\end{array}\to &4\\&#10;&#10;t=years\to &10&#10;\end{cases}

how about monthly?  well, there are 12 months in a year, so it will the compound cycle is 12, thus \bf \qquad \textit{Compound Interest Earned Amount}&#10;\\\\&#10;A=P\left(1+\frac{r}{n}\right)^{nt}&#10;\qquad &#10;\begin{cases}&#10;A=\textit{current amount}\\&#10;P=\textit{original amount deposited}\to &\$7000\\&#10;r=rate\to 5\%\to \frac{5}{100}\to &0.05\\&#10;n=&#10;\begin{array}{llll}&#10;\textit{times it compounds per year}\\&#10;\textit{monthly, 12 months, thus}&#10;\end{array}\to &12\\&#10;&#10;t=years\to &10&#10;\end{cases}

The dimensions in inches of a shipping box can be expressed as width x, length x+1, and height x-4. The volume is 84ft sq. Find
DENIUS [597]
X * (x + 1) * (x -4) = 84
x^2 + x * (x -4) = 84
x^3 + x^2 -4x^2 -4x = 84
x^3 - 3x^2 -4x -84 = 0
Using the cubic equation calculator:
http://www.1728.org/cubic.htm
x = 6
width 6
length 7
height 2
