w = √2 (cos(π/4) + i sin(π/4)) = √2 (1/√2 + i/√2) = 1 + i
z = 2 (cos(π/2) + i sin(π/2)) = 2i
Then
w - z = (1 + i) - 2i = 1 - i
so that
|w - z| = √(1² + (-1)²) = √2
and
arg(w - z) = -π/4
In polar form, we have
w - z = √2 (cos(-π/4) + i sin(-π/4)) = √2 (cos(π/4) - i sin(π/4))
Answer:
$1800
Step-by-step explanation:
12000(1+0.05x 3)
= 13800
13800 - 12000
$1800
If Z is the centroid of ABC , AZ = 2/3 AY and ZY = 1/3 AY
which means that: ZY = 1/2 AZ = 1/2 x 12 = 6
