Answer:

Step-by-step explanation:

see the figure below

As O is mid point of rectangle

distance between O to AB and DC is same

also distance between O to AD and BC is same

OP and OQ are perpendiculars so it is straight

and OP divides AB into equal segments as distance between O to AD and BC is same

same goes with OQ

I need help plz. Its DeMoivres Theorem

vagabundo [1.1K]

$\bf \qquad \textit{power of two complex numbers} \\\\\ [\quad r[cos(\theta)+isin(\theta)]\quad ]^n\implies r^n[cos(n\cdot \theta)+isin(n\cdot \theta)] \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ z=\stackrel{a}{-1}\stackrel{b}{-\sqrt{3}~i}~~ \begin{cases} r=\sqrt{a^2+b^2}\\ \theta =tan^{-1}\left( \frac{b}{a} \right)\\[-0.5em] \hrulefill\\ r=\sqrt{(-1)^2+(\sqrt{3})^2}\\ \qquad \sqrt{4}\\ \qquad 2\\ \theta =tan^{-1}\left( \frac{-\sqrt{3}}{-1} \right)\\\\ \qquad \frac{4\pi }{3} \end{cases}$

$\bf z=2\left[ cos\left( \frac{4\pi }{3} \right) -i~sin\left( \frac{4\pi }{3} \right)\right]\implies z^6=\left[ 2\left[ cos\left( \frac{4\pi }{3} \right) -i~sin\left( \frac{4\pi }{3} \right)\right] \right]^6 \\\\\\ z^6=2^6\left[ cos\left( 6\cdot \frac{4\pi }{3} \right) -i~sin\left( 6\cdot \frac{4\pi }{3} \right)\right]\implies z^6=64[cos(8\pi )-i~sin(8\pi )] \\\\\\ z^6=64[(-1)-i~(0)]\implies z^6=\stackrel{\stackrel{a}{\downarrow }}{-64}~~\stackrel{\stackrel{b}{\downarrow }}{-0i}$

Cloud [144]

Answer: 100

500 Is 100%

500 ÷ 100 = 5

5 Is 1%

5 x 20 = 100

100 Is 20%

svetlanas hair is 4 centimeters long her hair grows 1.5 centimeters per month. Svetlana wants her hair to be less than 16 centim

Temka [501]

Answer:

I guess the question is when her hair will be almost 16cm long.

So she needs to grow hair almost 12 cm of hair. Because 16-4=12

To grow 12cm hair she needs 8 months (12/1.5=8)

So Svetlana needs to cut her hair before 8th month.
