Find the modulus and argument for each of the folowing complex numbers.
a. z1 =
2 + 1
2 i
b. z2 = 2 + 2√3i
c. z3 = −3 + 5i
d. z4 = −2 − 2i
e. z5 = 4 − 4i
f. z6 = 3 − 6i

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.
