Given that
z₁ = 15 (cos(90°) + i sin(90°))
z₂ = 3 (cos(10°) + i sin(80°))
we get the quotient z₁/z₂ by dividing the moduli and subtracting the arguments:
z₁/z₂ = 15/3 (cos(90° - 10°) + i sin(90° - 10°))
z₁/z₂ = 5 (cos(80°) + i sin(80°))
so that z₁ is scaled by a factor of 1/3 and is rotated 10° clockwise.
The class will spend 19.32 on bookmarks
$0.84 x 23 = 19.32
You have to do this because the answe is the 2nx
Area = pi x radius squared... so
a = pi x 10in^2
a = 314.159
Answer:
60% are girls
Step-by-step explanation:
80 x 1.5 = 120 which is the amount of girls
120 out of 200 is 12/20 or 3.5 which is 60%
