9514 1404 393

Answer:

  4096∠0°

Step-by-step explanation:

The polar form of the base value is 2∠120°. Then the 12-th power is ...

  (2^12)∠(12×120°) = 4096∠0° . . . . or θ = 0 radians, as you wish

_____

I prefer the simpler notation r∠θ, rather than ...

  r(cos(θ) +i·sin(θ))   or   r·cis(θ)   or   r·e^(iθ)

You might not see this notation very often in areas outside of electrical engineering.

Answer:

Step-by-step explanation:

2(1 + W) = P\\Divide -both-sides-of-the-equation-by ; 2\\\frac{ 2(1 + W) }{2} = \frac{P}{2} \\1+ W = P/2\\W = \frac{P}{2} -1\\\\(b .)  2y = 10x + 6\\Re -write -in -slope-intercept-form : y= mx+b\\\frac{2y}{2} =\frac{10x}{2} +\frac{6}{2} \\y = 5x + 3\\Gradient = 5

Can someone help me with this?
hammer [34]

Answer:

Shaded area is 55 units²

Step-by-step explanation:

Ignoring the white cutout, we have a rectangle of length 10 and width 7 (count the squares in each direction).  The area of this larger rectangle is

(10 units)(7 units) = 70 units².  The white area that we previously ignored has dimensions 3 by 5 units, and thus an area of 15 units²  

Subtract the latter from the former, obtaining the net area

70 units² - 15 units² = 55 units²
