Answer:

The required rectangular form of the given complex polar form :

z1 = -3√2 - 3√2i

Step-by-step explanation:

z_1=6[\cos (\frac{5\pi}{4}) + i\sin(\frac{5\pi}{4})]...........(1)\\\\Now,\cos (\frac{5\pi}{4})=\cos(\pi+\frac{\pi}{4})\\\\=-\cos(\frac{\pi}{4})\\\\=-\frac{1}{\sqrt{2}}\\\\And,\sin (\frac{5\pi}{4})=\sin(\pi+\frac{\pi}{4})\\\\=-\sin(\frac{\pi}{4})\\\\=-\frac{1}{\sqrt{2}}

On substituting the obtained values in equation (1)

z_1=6[\frac{-1}{\sqrt{2}}-i\cdot \frac{1}{\sqrt{2}}]\\\\\implies z_1=-3\sqrt{2}- 3\sqrt{2}\cdot i

Hence, the required rectangular form of the given complex polar form :

z1 = -3√2 - 3√2i

Jared started a new job. On the first day he had orientation and worked for 2 hours. On the second day he trained for 4 hours. A
tresset_1 [31]

Answer:

Jared worked 11 days as full 8-hour days.

Step-by-step explanation:

We have:

First day = 2 h

Second day = 4 h

After that = 8 h each day    

Since his paycheck shows 94 hours of work, we can find the number of days that he works 8-hour day:

94 h = 2 h + 4 h + 8 h*x

Where x is the number of days that he works 8-hours.

8 h*x = 88 h

x = \frac{88 h}{8 h} = 11

 

Therefore, Jared worked 11 days as full 8-hour days.

I hope it helps you!

What happens to the volume of a sphere when the radius is multiplied by 4?
tekilochka [14]
Vsphere=(4/3)pir^3
Voriginal=(4/3)pir^3

when radius is multiplied by 4
replace r with 4r
Vnew=(4/3)pi(4r)^3
Vnew=(4/3)pi(64r^3)
Vnew=(64)(4/3)pir^3
Vnew=(64)(Voriginal)
the volume is 64 times the original

A self at a bookstore displays 27 books. Of these 27 books, 9 of the books are nonfiction books. The store owner adds 6 new fict
mrs_skeptik [129]
Right now, the ratio of nonfiction to fiction is 9:18.  If this is reduced, it is a ratio of 1:2, so there needs to be twice as many fiction books as nonfiction.

If we add 6 fiction books, we have 24 fiction books.  We can now set up this equation:

\frac{1}{2} = \frac{x}{24}

Now we cross multiply

2x=24

We can solve for x by dividing both sides by two, so:

x = 12.  There will be 12 nonfiction books.
