How do you write a quotient as a complex number?.
To see the Polar form and Rectangular form of quotient as a complex number.
Polar numbers can be written in two different forms: rectangular and polar. Rectangular complex numbers are given by a + bi, where a represents the real part of the complex number and b represents the imaginary part of the complex number. Polar complex numbers are given by its absolute value,
r = [tex]\sqrt{x^{2} +y^2}[/tex] and the argument, θ, which can then be determined through the following relations:
x = rcosθy = rsinθ[tex]z=re^i^\theta[/tex]
If the complex numbers are in polar form, then the quotient is given by:
[tex]\frac{z_1}{z_2}=\frac{r_1e^i^\theta_1}{r_2e^i^\theta_2}[/tex] [tex]= \frac{r_1}{r_2}e^i^(^\theta_1^-^\theta_2^)[/tex]
If the complex numbers are in rectangular form, then you will have to use the complex conjugate to remove the complex number in the denominator:
[tex]\frac{a_1+b_1i}{a_2+b_2i}[/tex] [tex]=\frac{(a_1+b_1i)(a_2-b_2i)}{(a_2+b_2i)(a_2-b_2i)}[/tex].

Graph the equation and find the y-value of the ordered pair when x=-5
See what x is when y=-5
Graph the equation and look at the table to find the y-value when x=-5
Answer: The option that is NOT a possible way to evaluate the function and find the correct answer is
See what x is when y=-5
Explanation:
In the function f(x) = 3x^2 - 2x + 5, x is the input variable and y is the output variable. To find the value of f(-5), we need to substitute -5 wherever there is an x in the function and then solve the resulting expression. This is the first option.
The second and forth options are also correct ways to evaluate the function, they involve graphing the equation and finding the y-value of the ordered pair when x=-5.
But the third option is not the correct way, because it is asking to find x when y=-5, but in the given function the y is unknown, so it is not possible to find x when y=-5.

the area of the bottom of a triangular upright prism is 4 cm2 and the areas of the sides are 9 cm2, 10 cm2 and 17 cm2. calculate the volume of the prism
To calculate the volume of a triangular prism, you need to know the base area and the height. In this case, the base area is given as 4 cm^2, and the areas of the sides are given as 9 cm^2, 10 cm^2 and 17 cm^2.
To find the volume of the prism, you can use the formula:
Volume = Base Area x Height
Since we don't know the height of the prism, we can use the area of the sides to find the height.
To find the height, we need to use the formula of area of the triangle.
Area = (1/2) x b x h
let's use the area of one side (for example 9cm^2)
9cm^2 = (1/2) x b x h
we can divide both sides by (1/2) x b
h = (2 * 9cm^2) / b
Now we have the height of the triangular prism, so we can use that to find the volume.
so the volume of the triangular prism = Base Area x Height = 4cm^2 x ( (2 * 9cm^2) / b) = 72/b cm^3
As we don't know the value of b, we can't find the exact volume of the prism.
Answer:
12 cm³
Step-by-step explanation:
Conditions:
a * h = 9 cm
b * h = 10 cm
c * h = 17 cm
S = 4 cm²
To calculate the area on three sides, we use the Heron formula:
[tex]S = \sqrt{p * (p-a) *(p-b)*(p-c)[/tex]
where "p" is the semi-perimeter:
[tex]p = \frac{(a+b+c)}{2}[/tex]
Let's express the sides in terms of the height:
a = 9/h
b = 10/h
c = 17/h
Then the semiperimeter will be:
p = (9/h+10/h+17/h) : 2 = 36/h : 2 = 18/h
Substituting the values into the Heron formula:
4 = √(18/h * (18/h - 9/h) * (18/h - 10/h) * (18/h - 17/h))
4² = 18/h * (18/h - 9/h) * (18/h - 10/h) * (18/h - 17/h)
16 = 18/h * 9/h * 8/h * 1/h
16 = 1296 / h^4
h^4 = 1296 / 16 = 81
h = 3 cm
Now we can calculate the volume of the pyramid:
V = S * h = 4 cm² * 3 cm = 12 cm³

Step-by-step explanation:
The slope-intercept formula of a line is: y = mx + b
m = slope
b = y-intercept
We know one point already.
3 = 3(5) + b
3 = 15 + b
3 - 15 = 15 - 15 + b
-12 = b

How do you solve for range of x?.
Range of x is a way of expressing the set of all possible values for a given variable x.
In order to solve for the range of x, we first need to identify the equation or expression that relates x to other variables. Once we have the equation, we can then solve for the range of x by determining the minimum and maximum possible values for the variable.
For example, if we have the equation x = 3y + 6, we can solve for the range of x by first setting y equal to its minimum and maximum possible values. If we assume y can take values between 0 and 10, then we can solve for the range of x by setting y equal to its minimum (0) and maximum (10) values, respectively.
As we can see in this instance, the x is 6 = x = 36.
In general, to solve for the range of x we need to:
1. Identify the equation or expression that relates x to other variables.
2. Set the other variables to their minimum and maximum possible values.
3. Solve for the minimum and maximum possible values for x.
4. The range of x is the set of all values between the minimum and maximum possible values for x.

As a result, there is just one transformation from shape A to shape B: dilate A by 1/2, followed by a 180 degree rotation.
Explain about the single transformation?A drastic change in shape or appearance is called a transformation. An crucial occasion, such as receiving your driver's licence, enrolling in college, or getting married, might change the course of your life. Extreme, dramatic change is what we refer to as transformation.
When we move a figure in any direction, we say that we are translating. Flipping a figure over a line is what is meant by reflection. Rotation is the process of rotating a figure around a point by a specific amount. When we dilate a figure, it is enlarged or shrunk.
By multiplying the original shape by a scale factor, we can change the size of the shape and make it bigger or smaller. This type of modification is called an expansion.
A shape can be transformed by shifting its location and size.
Shape A can only be transformed into shape B by rotating 180 degrees and enlarging it by half.
Based on the figure, we can:
Shape A's side lengths are twice as long as Shape B's side lengths.
After dilatation, shape A can be rotated 180 degrees to imprint onto shape B.
The range of dilatation from shape A to shape B is thus:
Scale = 1/2
As a result, there is just one transformation from shape A to shape B: dilate A by 1/2, followed by a 180 degree rotation.

write an equation for a degree 6 polynomial with a root at 3, a double root at 2, and a triple root at -1, and has a y-int at 5..
The equation of the degree 6 polynomial with a root at 3, a double root at 2, and a triple root at -1, and y-intercept at y = 5 is given as follows:
y = -5/12(x - 3)(x - 2)²(x + 1)³.
How to define the polynomial?The equation of the function is obtained considering the Factor Theorem, as a product of the linear factors of the function.
The zeros of the function, along with their multiplicities, are given as follows:
Zero at x = 3 with a multiplicity of 1.Zero at x = 2 with a multiplicity of 2.Zero at x = -1 with a multiplicity of 3.Then the linear factors of the function are given as follows:

A peron took a loan of R 150000for tw year at the rate of 10% annual compound interet To reduce interet and loan partly he paid R 85000 at the end of firt year
a) Now how many rupee hould he have to pay at the end of econd year to clear hi debt
b) If he had paid the loan only at the end of econd year how much le or more interet hould have to be paid?
Therefore, if the borrower had paid the loan just at the end of the second year, he would have owed R 167250. The additional interest due would be R 167250 - 150000 = R 17250.
a) To calculate the amount of money that the person would have to pay at the end of the second year to clear his debt, you can use the formula for compound interest:l,
A = P(1 + r/n)^(nt)
Where A is the final amount, P is the initial principal, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years.
In this case, the person took a loan of R 150000 for 2 years at an annual interest rate of 10%. He paid R 85000 at the end of the first year. So, the new principal at the beginning of the second year is P = 150000 - 85000 = 65000.
So, A = P(1 + r/n)^(nt)
A = 65000(1 + 0.1)^2
A = 65000*1.1^2
A = 73,650
So, the person should have to pay R 73650 at the end of the second year to clear his debt.
b) If the person had paid the loan only at the end of the second year, the interest would have been calculated on the original principal of R 150000 for 2 years. So,
A = P(1 + r/n)^(nt)
A = 150000(1 + 0.1)^2
A = 150000*1.1^2
A = 167250
So, the person would have had to pay R 167250 if he had paid the loan only at the end of the second year. Therefore, he would have to pay more interest of R 167250 - 150000 = R 17250.

Alyson deposits $500 in the bank for 12 years. The bank offers her a 4% interest rate compounded monthly. How much money will be in her account at the end
of the 12 years? (Remember to round your answer to the nearest cent.)
Answer:$917.59
Step-by-step explanation:
The formula for compound interest is A = P(1 + r/n)^(nt) where A is the final amount, P is the principal (initial deposit), r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years.
In this case, the initial deposit is $500, the annual interest rate is 4%, the number of times compounded per year is 12 (monthly), and the number of years is 12.
So, we can plug in the values into the formula:
A = $500(1 + 0.04/12)^(12*12) = $500(1.003333333)^(144) = $500(1.835170816) = $917.585
The final amount in her account after 12 years is $917.58
To round to the nearest cent, we can use the following method:
If the digit in the thousandths place is less than 5, we keep the hundredths digit as is.
If the digit in the thousandths place is greater than 5, we round up the hundredths digit.
In this case the digit in the thousandths is 5 so, we have to round up the hundredths digit of $917.58.
What is the y-intercept of Y =- 4x 6?.
The y-intercept of the equation y = -4x-6 is (0, -6).
Equation: y = -4x - 6
The y intercept of a graph is the point where the graph intersects the y-axis. We know that the x-coordinate of any point on the y-axis is 0. So the x-coordinate of a y-intercept is 0.
Use the slope-intercept form to find the slope and y-intercept.
The slope-intercept form is
y = mx + b, where m is the slope and b is the y-intercept.
y = mx + b
Find the values of m and b, using the slope-intercept equation.
Now, using this information,
y = −4x − 6
y = mx + c
m → slope
the slope is −4 and

What does a 360 angle look like?.
A 360-degree angle can be visualized as a full rotation or circle, and it is often used to measure angles in a circular context.
A 360-degree angle is a complete rotation and is equivalent to one full circle. It is often represented as a circle with a line that goes from the center of the circle to the outer edge, marking the angle.
When looking at a 360-degree angle, it can be divided into four quadrants: the top right, top left, bottom left, and bottom right. Each quadrant is 90 degrees or one-fourth of the total angle. This division is useful when analyzing or measuring angles in different sections of a circle.
In terms of visual representation, imagine a clock face with the numbers 1-12. The clock face is a 360-degree angle, with each number representing a 30 degree increment. The hour hand of the clock would rotate around the face, completing a full rotation and reaching the starting point at the 12 o'clock position, completing a 360 degree angle.
In other words, a 360 degree angle can be visualized as a full rotation or circle, and it is often used to measure angles in a circular context. It can also be divided into smaller sections for analysis or measurement purposes.

Jutin broke a cell ample into 1010 batche, each weighing 8. 8\time 10^{-6}8. 8×10 −6 gram. How much did the original ample weigh? Ue cientific notation to expre your anwer
The weight of the original sample is [tex]8.8 *10^{-6}[/tex] grams/batch * 1010 batches is 880 grams.
To find the weight of the original sample, we can multiply the weight of each batch by the number of batches.
The weight of each batch is [tex]8.8 * 10^-6[/tex] grams.
And the total number of batches is 1010.
So, the weight of the original sample is:
[tex]8.8 * 10^{-6}[/tex] grams/batch * 1010 batches = 8.8 x 10^-6 * 1010 grams
= [tex]8.8 * 10^{-6} * 10^3 *10^1[/tex]grams
=[tex]8.8 * 10^{-3} * 10^1[/tex] grams
= [tex]8.8 * 10^{-2}[/tex] grams
= [tex]8.8 * 10^{-2} * 10^3[/tex]
=[tex]8.8 * 10^1[/tex] = 880 grams
So the original sample weighed 880 grams.

Help Ive been stuck on this for days
Jamie took 20 pieces of colored paper and put them in a hat. Eight pieces were red, three pieces were blue, and the rest were green. She pulls a piece of paper out of the hat. What are the chances that the paper is red?
A. 0.04
B. 0.4
C. 1.6
D. 1.2
Answer:
B. 0.4
Step-by-step explanation:
Probability (picking red paper) = preferred/sample
Preferred outcome (picking red) = 8 pieces.
Sample size is total outcome (paper in hat) = 20 pieces.
P(picking red paper) = 8/20
P(red) = 0.4 or 40%
