Use demovires theorem to write the complex number in trigonometric form.
Anastasy [175]
\sqrt3+i=2\left(\dfrac{\sqrt3}2+\dfrac12i\right)

\begin{cases}\cos\dfrac\pi6=\dfrac{\sqrt3}2\\\\\sin\dfrac\pi6=\dfrac12\end{cases}

\implies\sqrt3+i=2e^{i\pi/6}

By DeMoivre's theorem,

(\sqrt3+i)^3=(2e^{i\pi/6})^3=8e^{i\pi/2}=8\left(\cos\dfrac\pi2+i\sin\dfrac\pi2\right)=8i

Find the slope of the line that passes through the pair of points. F(–6, 8), P(–6, –5)
Anika [276]

Answer:

slope is undefined

Step-by-step explanation:

Calculate the slope m using the slope formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 6, 8) and (x₂, y₂ ) = (- 6, - 5)

m = \frac{-5-8}{-6+6} = \frac{-13}{0}

division by zero is undefined, hence slope is undefined
