Which of the following equations represents the graph shown?

melomori [17]

Answer: Last option.

Step-by-step explanation:

The equation of the line in slope-intercept form is:

$y=mx+b$

Where m is the slope and b the intersection with the y-axis.

You can observe in the graph that the line passes through the origin, then:

$b=0$

Choose two points of the line and calculate the slope with:

$m=\frac{y_2-y_1}{x_2-x_1}$

Points: (2,3) and (-2,-3)

Substitute values, then the slope is:

$m=\frac{-3-3}{-2-2}=\frac{-6}{-4}=\frac{3}{2}$

Substituting "m" and "b" into $y=mx+b$ , you get that the equation is:

$y=\frac{3}{2}x$

This can be written as:

$f(x)=\frac{3}{2}x$

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

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