For this case we have the following point:
i - 2
The first thing you should remember is that in a complex number plane:
The vertical axis represents the imaginary part.
The horizontal axis represents the real part.

When Gail goes on a hike, she always packs a ratio of 20 protein bars to 15 water bottles in her backpack.

stealth61 [152]

Answer:

4 protein bars

Step-by-step explanation:

if we divide the 15 water bottles by 5 we get 3 water bottles. This is how many she took so following the same scale factor we would then divide 20 by 5 and get 4.

Express the complex number in trigonometric form. 3 - 3i radians pls

belka [17]

$\bf \begin{array}{llll}
3&-&3i\\
\uparrow &&\uparrow \\
a&&b
\end{array}\qquad 
\begin{cases}
r=\sqrt{a^2+b^2}\\
\theta=tan^{-1}\left( \frac{b}{a} \right)
\end{cases}\\\\
-----------------------------\\\\
r=\sqrt{3^2+3^2}\implies r=\sqrt{18}\implies r=3\sqrt{2}
\\\\\\
tan(\theta)=\cfrac{3}{3}\implies tan(\theta)=1\implies \measuredangle \theta=tan^{-1}(1)
\\\\\\
\measuredangle \theta=\frac{\pi }{4}\impliedby \textit{reference angle}$

now, b is -3, and a is 3
or in rectangular if you wish, y = -3 and x = 3.... on what quadrant is "y" negative and "x" positive? well, the 4th quadrant
so, using our reference angle, that'd be $\bf \cfrac{7\pi }{4}\quad or \quad -\cfrac{\pi }{4}$

so, let's use the first one

$\bf (3,3i)\implies 
\begin{array}{llll}
r[cos(\theta)+i\ sin(\theta)]\\\\
3\sqrt{2}\left[ cos\left( \frac{7\pi }{4} \right)+i\ sin\left( \frac{7\pi }{4} \right) \right]
\end{array}$
