I need this answer asap
padilas [110]

Answer:

a=64,b=0

Step-by-step explanation:

Given;

z=-1-\sqrt{3}i

r=\sqrt{(-1)^2+(-\sqrt{3})^2} =2

\phi =\tan^{-1}(\frac{-\sqrt{3} }{-1})=\frac{\pi}{3}

\arg(z)=2\pi-\frac{\pi}{3} =\frac{5\pi}{3}

Apply DeMoivre's Theorem;

z^n=r^n(\cos(n \theta) + i\sin(n \theta))

\Rightarrow z^6=2^6(\cos(6\times \frac{5\pi}{3}) + i\sin(6\times \frac{5\pi}{3}))

\Rightarrow z^6=64(\cos(10\pi) + i\sin(10\pi))

\Rightarrow z^6=64(1+ 0i)

\Rightarrow z^6=64+ 0i

\therefore a=64,b=0

Which of the following is an example of a quadratic equation
raketka [301]

Answer:

x

2

=36x, start superscript, 2, end superscript, equals, 36

(x-2)^2=49(x−2)

2

=49left parenthesis, x, minus, 2, right parenthesis, start superscript, 2, end superscript, equals, 49 [Why is this a quadratic equation?]

x^2

x, start superscript, 2, end superscript(x-2)^2

left parenthesis, x, minus, 2, right parenthesis, start superscript, 2, end superscriptxx

\begin{aligned}(x-2)^2&=49\\\\ x^2-4x+4&=49\end{aligned}

 

x^2

x, start superscript, 2, end superscript

2x^2+3=1312x

Find the new amount given the original amount and the percent of change.
ella [17]

Answer:

New Amount = $9.8

Step-by-step explanation:

Original amount  = $ 7

Percentage increase = 40%

Increase in amount = 40\% \ of\ 7 = \frac{40}{100}\times 7=\frac{280}{100} = \$2.8

New amount = \textrm{Original amount + Increase} = \$7+\$2.8=\$9.8

New Amount = $9.8
