Answer:
8(cos(π) +i·sin(π))
Step-by-step explanation:
The number in parentheses has a magnitude of ...
√(1^2 +(√3)^2) = √4 = 2
Then the cube of that number will have a magnitude of 8, eliminating the 2nd and 4th choices
The angle of the number in parentheses is ...
arctan(-√3/1) = -π/3
Then 3 times that angle will be -π, also π.
The number of interest has a magnitude of 8 and an angle of π, so is written in the desired form as ...
8(cos(π) +i·sin(π)) . . . . . matches the 3rd choice
Answer:
what following data
Step-by-step explanation:
Answer:
-8x-8
Step-by-step explanation:
Since 16x and -24x have like variables, we can subtract to get -8x. Then, we can add the constants to get -8.
Answer:
$666.66
Step-by-step explanation:
4%/12=0.33333
0.33333*9= 3%
2,000/3=$666.66
2,000+666.66=$2,666.66
(-6 + x) 1 6
-------- = --- - --
x^3 x^4
