Answer:
C
Step-by-step explanation:
-5.5-11.2
change the subtraction to addition
5.5+11.2= 16.7
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.
<span>3 feet make 1 yard.
40 feet make 13 and 1/3 yards
So that is 13 yards to nearest </span>
