Expres each complex number in polar form. State the arguments in radians rounded to the nearest thousandth.

Arlecino [84]

Answer:

(a) In polar form complex number will be $5.3851\angle 68.1985^{\circ}$ and in radian argument is 0.378π

(b) $6.0827\angle -9.46^{\circ}$

angle will be 0.05255π

Step-by-step explanation:

We have given

(a) 2+5i

We have to represent in polar form

We know that magnitude is given by $\sqrt{(real\ part)^2+(imaginary\ part)^2}=\sqrt{2^2+5^2}=\sqrt{29}$

Argument is given by $tan^{-1}\frac{imaginary\ part}{real\ part}=tan^{-1}\frac{5}{2}=68.198$

So in polar form complex number will be $5.3851\angle 68.1985^{\circ}$

In radian argument will be $68.1985\times \frac{\pi }{180}=0.378\pi$

(b) We have given complex number $-6+i$

We know that magnitude is given by $\sqrt{(real\ part)^2+(imaginary\ part)^2}=\sqrt{(-6)^2+1^2}=\sqrt{37}$

Argument is given by $tan^{-1}\frac{imaginary\ part}{real\ part}=tan^{-1}\frac{1}{-6}=-9.46$

So in polar form complex number will be $6.0827\angle -9.46^{\circ}$

In radian argument will be $-9.46\times \frac{\pi }{180}=-0.05255\pi$

How do you know 72/80 is greater than 7/8? Explain

dangina [55]

Answer:

Step-by-step explanation: I know that 72/80 is greater than 7/8 because when we make 7/8 as the same denominator as of 72/80 it is only 70/80 which is smaller than 72/80.

A shipment of 24 electric typewriters are rejected if 3 are checked for defects and at least 1 is found to be defective. Find th

Maslowich

Answer:

You keep them if you test 3 and all pass.

There are 18 good ones and 6 bad (making 24)

Chance of first passing is 18/24

If it passes, there are now one less good and one less total.

Chance of second passing is 17/23

If it passes, there are now one less good and one less total.

Chance of second passing is 16/22

Total is (16 x 17 x 18) / (22 x 23 x 24) = about 0.4 (0.403162055 is you really want to know).

So probability all are ok is 0.4

Thus probability you find at least one bad one is 0.6

Hope this helps you out!

Solve for n: 4^n×2^-18=1

Bad White [126]

One way to do it is by cleverly rewriting terms and using some basic algebraic identities:

$4^n\cdot 2^{-18}=1$ .

$2^{2n-18}=2^0$ .

$2n-18=0$ .

$n=18/2=\boxed{9}$ .

Another way would be to use logarithms, namely:

$4^n\cdot2^{-18}=1\implies n=\log_4\Big({\frac{1}{2^{-18}}}\Big)=\boxed{9}$ .

Hope this helps.
