Z=32(cos(n/3) + isin(n/3)

Arturiano [62]

Recall that

$\bf r[cos(\theta )+i~sin(\theta )]\quad 
\begin{cases}
x=rcos(\theta )\\
y=rsin(\theta )
\end{cases}\implies (x,y)\\\\
-------------------------------\\\\$

therefore,

$\bf Z=\stackrel{r}{32}\left[cos\left( \stackrel{\theta }{\frac{n}{3}} \right)+i~ sin\left( \stackrel{\theta }{\frac{n}{3}} \right)\right]\qquad 
\begin{cases}
r=32\\
\theta =\frac{n}{3}
\end{cases}\implies 
\begin{cases}
x=32cos\left( \frac{n}{3} \right)\\\\
y=32sin\left( \frac{n}{3} \right)
\end{cases}
\\\\\\
\left[ 32cos\left( \frac{n}{3} \right)~~,~~ 32sin\left( \frac{n}{3} \right)\right]$

A store sells 4 cans of for 11 dollars how much would it cost to buy 9 cans

Kruka [31]

4/11 = 9/x......4 cans to 11 = 9 cans to x
cross multiply
(4)(x) = (11)(9)
4x = 99
x = 99/4
x = 24.75 for 9 cans

or this way..
4 cans for 11 = 11/4 = 2.75 per can...for 9 cans = 9 * 2.75 = 24.75

same answer either way :)
