Consider z = 3StartRoot 3 EndRoot + 3i. What happens to the modulus and argument when z is raised to the 4th power?
Answer:
It's A
Step-by-step explanation:
Just took it and it matches
The modulus increased by 216 and the argument increased by π/2. Option A is correct
The number that constitutes of real and imaginary numbers are called complex numbers.
[tex]z = 3\sqrt{3} + 3i\\z^4 = (3\sqrt{3} + 3i)^4\\z^4 = 648(-1+\sqrt{3}i )[/tex]
Modulus and argument of [tex]z^4[/tex] is given by.
[tex]|z^4| = 648\sqrt{1+3} \\|z^4| = 648\sqrt{4} \\|z^4| = 648*2\\|z^4| = 1296[/tex]
argument
[tex]\theta=tan^{-1}(\sqrt{3} /-1)\\\theta=tan^{-1}(-\sqrt{3} )\\\theta= -\pi /3[/tex]
similarly, the Modulus and argument of z is given by.
Modulus
|z| = 6
argument
[tex]\theta=\pi /6[/tex]
Now comparing Modulos and argument of [tex]z^4[/tex] and z
[tex]z^4[/tex]/z = 1296/6 = 216
[tex]\theta=\pi /6+\pi /3\\\theta=\pi /2[/tex]
Thus, The modulus increased by 216 and the argument increased by π/2. Option A is correct.

11 more than a number q is negative 15 ; Solve for the variable.
Answer:
q = -26
Step-by-step explanation:
Set up an equation where q is the unknown number:
q + 11 = -15
Solve for q by subtracting 11 from both sides:
q + 11 = -15

solve for s: 6.49s + 8.32 = 27.79
Answer:
s=3
hope u have a great day
Answer:
s = 3
Step-by-step explanation:
STEPS FOR SOLVING LINEAR EQUATION
6.49s+8.32=27.79
Subtract 8.32 from both sides.
6.49s=27.79−8.32
Subtract 8.32 from 27.79 to get 19.47.
6.49s=19.47
Divide both sides by 6.49.
s=
6.49
19.47
Expand

The test tube is cold.
The test tube is warm.
The test tube is very hot.
The test tube is the same temperature as the air.
The test tube is cold best describes what is felt.
Option A is the correct answer.
What is a chemical reaction?A chemical reaction is a process that leads to the transformation of one set of chemical substances into another.
In other words, it is the process of breaking and forming chemical bonds between atoms to create new compounds with different properties than the original substances.
We have,
An endothermic reaction is a type of chemical reaction that absorbs heat from the surrounding environment, resulting in a decrease in temperature.
In this case,
The chemical reaction that occurred in the test tube absorbed heat from the surroundings, including the air and the test tube itself.
As a result, the temperature of the test tube decreased, making it feel cold to the touch.
Thus,
The test tube is cold best describes what is felt.

The square below represents one whole. Express the shaded area as a fraction, a decimal, and a percent of the whole.
Answer as a fraction = 1/2
Answer as a decimal = 0.5
Answer as a percent = 50%
========================================
Explanation:
There are 5 blue rectangles out of 10 total. This forms the fraction 5/10 and that reduces to 1/2 after dividing both parts by 5. Therefore, the fractions 5/10 and 1/2 are the same. Notice that exactly half of the entire figure is shaded blue.
Use long division or your calculator to find that 1/2 = 0.5 which converts to 50% when you move the decimal point 2 spots to the right.

What is the value of the expression -4.5 x -8.5?
Answer:
38.25 because both numbers are negative and a negative number times a negative number is a positive number.
Step-by-step explanation:
When you multiply just forget about them being negative for a little, and move the decimal to the right until you have a integer (a whole number not a fraction/decimal). Than multiply it how you normally multiply, now that you have 3825 you have to add the number of spots you moved the decimals which is two one for the top one for the bottom, which is 2 places and then move the decimal 2 places to the left in our number which will make it 38.25. Both numbers are negative and a negative number times a negative number is a positive number. So yeah. :D

A construction crew is extending a highway sound barrier that is 13 miles long. the crew builds 1/2 of a mile per week. Write an equation the represents the length Y (in miles) of the barrier after X weeks.
Answer:
y= 1/2x + 13
because the barrier is already 13 miles long, and they're adding 1/2 miles every week
The equation the represents the length Y (in miles) of the barrier after X weeks is y = (1/2)x + 13
A linear equation is in the form:
y = mx + b;
where m is the slope, b is the y intercept and y, x are variables.
Let y represent the length of the barrier after x weeks.
Since the crew builds 1/2 of a mile per week hence m = 1/2, Also the barrier is 13 miles long, hence b = 13, hence:
y = (1/2)x + 13
The equation the represents the length Y (in miles) of the barrier after X weeks is y = (1/2)x + 13
