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.
