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

X+y+z=1<br> 2x+4y+2z=-6<br> -X+9y-3z=-49<br> How can I solve this system of equations?
masya89 [10]

Answer:

Step-by-step explanation:

x + y + z = 1

-x + 9y - 3z = -49

10y - 2z = -48

2x + 4y + 2z = -6

-2x + 18y - 6z= -98

22y - 4z = -104

-20y + 4z = 96

2y = -8

y = -4

10(-4) - 2z = -48

-40 - 2z = -48

-2z = -8

z = 4

x - 4 + 4 = 1

x = 1

x = 1, y = -4, z = 4

What is ∑n=16[4(−5)n−1] equal to?
-Dominant- [34]

Answer:

This  will be the sum of a geometric series where the first term is 4

The common ratio  is -5

And we will have 6 terms.....so....the sum is

first term   [ 1  -  common ratio^number of terms ] / [ 1 - common ratio ]  =

4  [1 - (-5)^6]  /  [ 1  - -5 ]  =

4 [ 1 - 15625 ] / 6  =

(2/3) ( -15624 )  =

-10416
