Answer:
(-3, 3√3)
Step-by-step explanation:
Evaluate each of the coordinates. Keep or drop the "i" as your convention requires.
6(cos(120°), i·sin(120°)) = (6·cos(120°), i·6·sin(120°)) = (6(-0.5), i·6·√3/2)
= (-3, 3√3 i)
You may want the (x, y) coordinates written as (-3, 3√3).
___
In the complex plane, this is -3+i·3√3.
The answer is B) 20
Because you have 5 brands and you combine each with the 4 others, so 5*4=20

Answer:
3months
Step-by-step explanation:
target $1100
currently saved $1100
so we get the amount she need to save to get to the target.
$1100 - $110= $990 Need to be saved
saving rate 10% of $3300= $330 per month
to get the number of months she need to save, we divide amount needed by amount saved per month; $990 ÷ $330= 3months
