PRECALC QUESTION! Convert the polar representation of this complex number into its standard form: z = 2(cos 11pi/6+ i sin 11pi/6

Tanzania [10]

$\bf z=2\left[ cos\left( \frac{11\pi }{6} \right) + i\ sin\left( \frac{11\pi }{6} \right) \right]\qquad 
\begin{cases}
r=2\\
\theta=\frac{11\pi }{6}\\
-----\\
a=x=rcos(\theta)\\
b=y=rsin(\theta)
\end{cases}\implies a+bi
\\\\\\
2cos\left( \frac{11\pi }{6} \right)+2sin\left( \frac{11\pi }{6} \right)\ i\implies 2\cdot \cfrac{\sqrt{3}}{2}+2\cdot \cfrac{-1}{2}\ i\implies \sqrt{3}-1i
\\\\\\
\boxed{\sqrt{3}-i}$

Solve the system of linear equations by substitution. y=2x+5 and y=3x-1

Doss [256]

Plug in the second equation into the first equation for y.
$y = 2x + 5 \\ y = 3x - 1 \\ 3x - 1 = 2x + 5$
Now put the variable on one side and constants on the other
$3x - 1 + 1 - 2x = 2x - 2x + 5 + 1 \\ x = 6$
Now plug that back into one of the original equations
$y = 2x + 5 \\ y = 2(6) + 5 \\ y = 12 + 5 \\ y = 17$
So now you know
$x = 6 \\ y = 17$
Its always a good idea to check
$17 = 2(6) + 5 \\ 17 = 17 \\ 17 = 3(6) - 1 \\ 17 = 17$
