A picture could hold to 12th of a gallon of water if Roger filled up nine pictures how much water would he have
TEA [102]

Answer:

He would have a very soggy picture!

OR if you mean the pitcher holds one twelvth of a gallon, he will have 9/12 or 3/4 of a gallon.

OR if you mean the pitcher holds two twelvths of a gallon, he ends up with 9 × 1/6 which is one and a half gallons.

Step-by-step explanation:

Spelling is important! A "picture" could be a drawing, a photograph, or a painting.

"Pitcher" could be a container for pouring liquids or a player who pitches the ball in a baseball game.

I know you wanted math help, but it is difficult to answer if I can't tell whether "to" meant "two" or he filled the pitcher to pour twelvths.

Find (g o f)(-1). *
klio [65]

Answer:

D  -9

Step-by-step explanation:

(g o f)(-1) = g(f(-1))

f(-1) = f(-1)  =  (-1)^{2}  +  2(-1) - 3\\=  1 - 2 - 3\\=  -4

g(-4) = -4 - 5 = -9

So, (g o f)(-1) = -9

Find the complex fourth roots \[-\sqrt{3}+\iota \] in polar form.
____ [38]

Let z=-\sqrt3+i. Then

|z|=\sqrt{(-\sqrt3)^2+1^2}=2

z lies in the second quadrant, so

\arg z=\pi+\tan^{-1}\left(-\dfrac1{\sqrt3}\right)=\dfrac{5\pi}6

So we have

z=2e^{i5\pi/6}

and the fourth roots of z are

2^{1/4}e^{i(5\pi/6+k\pi)/4}

where k\in\{0,1,2,3\}. In particular, they are

2^{1/4}e^{i(5\pi/6)/4}=2^{1/4}e^{i5\pi/24}

2^{1/4}e^{i(5\pi/6+2\pi)/4}=2^{1/4}e^{i17\pi/24}

2^{1/4}e^{i(5\pi/6+4\pi)/4}=2^{1/4}e^{i29\pi/24}

2^{1/4}e^{i(5\pi/6+6\pi)/4}=2^{1/4}e^{i41\pi/24}
