Answer:

$h=2\frac{2}{3}in.$

Step-by-step explanation:

Formula

$A=\frac{hb}{2}$

Equation

$h=2\frac{A}{b}$

$h=2(\frac{2}{1.5})$

$h=2\frac{2}{3}$

Check

$2\frac{2}{3}$ · $1\frac{1}{2}=4$

Use DeMoivre's Theorem to find the following. Write your answer in<br> standard form.

valina [46]

Answer:

Option C.

Step-by-step explanation:

The given expression is

$\left(\sqrt{2}cis \dfrac{9\pi}{20}\right)^5$

It can be rewritten as

$\left(\sqrt{2}\cos \dfrac{9\pi}{20}+i\sin\dfrac{9\pi}{20}\right)^5$

According to De moivre's Theorem:

$[r(\cos\theta+i\sin \theta)]^n=r^n(\cos n\theta +i\sin n\theta)$

Using De moivre's Theorem, we get

$(\sqrt{2})^5\left(\cos \dfrac{9\pi\times 5}{20}+i\sin\dfrac{9\pi\times 5}{20}\right)$

$=4\sqrt{2}\left(\cos \dfrac{9\pi}{4}+i\sin\dfrac{9\pi}{4}\right)$

$=4\sqrt{2}\left(\cos (2\pi +\dfrac{\pi}{4})+i\sin (2\pi+\dfrac{\pi}{4})\right)$

$=4\sqrt{2}\left(\cos \dfrac{\pi}{4}+i\sin \dfrac{\pi}{4}\right)$

$=4\sqrt{2}\left(\dfrac{1}{\sqrt{2}}+i\dfrac{1}{\sqrt{2}}\right)$

$=4+4i$

Therefore, the correct option is C.

How many hours did Diana work of she was paid $45.50

JulijaS [17]

I think it would be C because the equation is y=7x. y=7x is also equal to x=1/7y. If y=45.50, then you would have to divide y by 7, which would equal 6.5.
