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.
Answer:
$350
Step-by-step explanation:
3 lawns --------------> $105
find unit rate:
1 lawn -------------> $105 ÷ 3 = $35 per lawn
10 lawns --------> $35 per lawn x 10 lawns = $350
