(the first option)
reason:
the 2 is a ( because that’s what is shown on the number line. infinity is also a ) because infinity can’t have a ]
Answer:
(2/9)cis(30°)
Step-by-step explanation:
We can express the two numbers in magnitude∠angle form, then find their ratio.
|z1| = 3√((-1)² +(√3)²) = 3√4 = 6
∠z1 = arctan((3√3)/(-3)) = -arctan(√3) = 120°
z2 = 27∠90°
So, the ratio is ...
z1/z2 = (6∠120°)/(27∠90°) = (6/27)∠(120°-90°)
z1/z2 = (2/9)∠30°
You would do 2 times 6 and get 12. Then you subtract 12 from -20 and you get -8. so -8 is your answer.
