$z^3=-1+i\sqrt3=2e^{i2\pi/3}$

$\implies z=\left(2e^{i2\pi/3}\right)^{1/3}=\begin{cases}2^{1/3}e^{i2\pi/9}\\2^{1/3}e^{i8pi/9}\\2^{1/3}e^{i14\pi/9}\end{cases}$

Plz hurry, brainliest and lots of points plz explain answer and only answer if you are actually gonna do it.

Answer and Step-by-step explanation:

1st box:

0, -3

2nd box

-2, -9/4

3rd box:

2, -3/2

4th box:

4, 0

Btw 0, -2, 2, 4 are in the x-coordinate column if you didn’t know, and 1, -9/4, -3/2 are in the y-coordinate column

Basically to solve if you plug in 0 into x, so basically it’s 3(0)-4y=12, which you simplify gives you 0-4y=12, subtract 0 from 12 which is 12 and then do 12 divided by -4 and then you get y = -3 and that’s how you get the box answer

Idk how to the rest srry lol!

Rod is paid $85 to install a screen door and $115 to install a wooden door. In one week he installed 18 doors and was paid a tot

Rainbow [258]

Answer:Rod installed 7 screen doors

Step-by-step explanation:

Step 1

Let the number of screen door = x

And the number of wooden doors = y

since he installed 18 doors , we have that

screen door + wooden doors = 18

x + y = 18------ equation 1

Also the cost to install a screen door -= $85

and to install a wooden door = $115

And he was therefore paid a total of $1850

Therefore

85x + 115 y = $1860------- equation 2

Step 2----- Solving

x + y = 18------ equation 1

85x + 115 y = $1860------- equation 2

Multiplying equation 1 BY 85

85x + 85y= 1530------- equation 3

85x + 115 y = $1860------- equation 4

subtracting from equation 1 from (2)

115y- 85y= 1860-1530

30y=330

y = 330/30 = 11

To find x

x+ y=18

x= 18-y

x= 18-11= 7

Rod installed 7 screen doors and 11 wooden doors.

(4x3 – 2x2 + 3x – 1) + (5r2 - x - 5). What is the sum ?

Lunna [17]

The sum is 4x³ + 3x² + 2x – 6.

Solution:

The correct question is given below.

(4x³ – 2x² + 3x – 1) + (5x² – x – 5). What is the sum?

To find the sum of the polynomial:

Sum of (4x³ – 2x² + 3x – 1) and (5x² – x – 5)

= (4x³ – 2x² + 3x – 1) + (5x² – x – 5)

Remove the parentheses.

= 4x³ – 2x² + 3x – 1 + 5x² – x – 5

Group like terms together.

= 4x³ – 2x² + 5x² + 3x – x – 1 – 5

Add the similar elements. i.e the element with same power.

= 4x³ + 3x² + 2x – 1 – 5

Subtract the constant terms.

= 4x³ + 3x² + 2x – 6

The sum is 4x³ + 3x² + 2x – 6.
