Which of the following cannot be in the solution set of w/-2 < 1? a) -1 b) 1 c) -2 d) 2

Tanzania [10]

Answer is c. -2 (cannot be in the solution set of w/-2)

because.

a) -1/-2 = 1/2 and 1/2 < 1

b) 1/-2 = -1/2 and -1/2 <1

d) 2/-2 = -1 and -1 <1

but

c) -2/-2 = 1 and 1 = 1

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;

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

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

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

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

$\Rightarrow z^6=64+ 0i$

$\therefore a=64,b=0$

Ivahew [28]

I suppose the two given numbers are the length of the two legs.
Pythagorean theorem: 385.7^2 + 321.84^2=hypotenuse^2
hypotenuse=502.34
