A) 3/8
B) 1/2
C) 5/8
D) 3/4

The correct answer is coplanar

EXPLANATION

Coplanar means the three points A , B and Q are on the same plane.

They are not colinear, because they are not in a straight line. It is only A and Q that are on the same straight line. If B had fallen in line with them, the three points would have been collinear as well.

Answer:

the answer is coplanar

The sum 1 + 3 + 5 + + 7 + 9 + ... + 39 in sigma notation is represented as ∑(from n=1 to n=20)[1 + (n-1)*2]. This notation communicates the series' progression and key characteristics.

The sum 1 + 3 + 5 + + 7 + 9 + ... + 39 can be represented in sigma notation as follows: Let the general term of this arithmetic series be a_n = 1 + (n-1)*2, where n is the term number. This formula is for a sequence where the difference between each number is 2 (an arithmetic sequence). Thus, the series 1 + 3 + 5 + + 7 + 9 + ... + 39 in sigma notation can be written as ∑(from n=1 to n=20)[1 + (n-1)*2]. Here, n = 1 is the starting point, n = 20 is the end point which is calculated by (39-1)/2 + 1 because the sequence is an arithmetic sequence with common difference 2 and first term 1, and 1 + (n-1)*2 is the formula for the nth term.

The sum 1 + 3 + 5 + ... + 39 can be written in sigma notation as Σ(1 + (i - 1)2) for i from 1 to 20.

To express the sum 1 + 3 + 5 + 7 + 9 + ... + 39 in sigma notation, we first need to realize that this is an arithmetic series where each term increases by 2. The first term a1 is 1, and the common difference d is 2. We can find the number of terms n in the series by using the formula for the nth term of an arithmetic sequence, which is an = a1 + (n - 1)d.

Since 39 is the last term, we have 39 = 1 + (n - 1)2, which simplifies to n = 20.Now we know our series goes from the 1st term to the 20th term, and the formula for the ith term is ai = 1 + (i - 1)2. Therefore, the series in sigma notation is written as:  Σ(1 + (i - 1)2) for i from 1 to 20.

180° rotation about the origin changes the signs of the coordinates.

(x, y) → (-x, -y)

It is a reflection over the y-axis and a reflection over the x-axis (in either order).

You did not provide the options so hopefully you can figure out the answer based on the information I provided.

Answer:

The transformation of the triangle MNO will be first a reflection respect to the x-axis and second a reflection over the y-axis.

Step-by-step explanation:

By definition a coordinate transformation from 180° rotation round the origen can be expressed as:

(x,y) ---> (-x,-y)

On the other hand, the coordinate transformation of the reflection over x- axis is:

(x,y) ---> (x,-y)

And the reflection over the y-axis of the this transformation is:

(x,-y) ---> (-x,-y)

That result the same transformation than the 180° rotation.

Answer:

hours worked; amount of money earned; 0 to 30; $0 to $330

Step-by-step explanation:

Let

y ----> the amount earned per week

x ----> the number of hours worked by week

In this problem

the amount earned per week (variable y) represent the dependent quantity

the number of hours worked by week (variable x) represent the independent quantity

therefore

The domain is the interval -----> [0,30] (the maximum number of hours per week is 30)

The range is the interval -----> [0,11*30] ----> [0,330] (the maximum amount earned per week is $330)

therefore

independent quantity is hours worked

dependent quantity is amount of money earned

domain is 0 to 30

range is $0 to $330

Final answer:

The independent quantity is hours worked and the dependent quantity is the amount of money earned, with a domain of 0 to 30 hours and a range of $0 to $330.

Explanation:

In the given scenario where Uan earns $11 per hour and works at most 30 hours per week, the independent quantity is the hours worked, and the dependent quantity is the amount of money earned. This is because the money earned depends on the number of hours worked.

The domain represents the possible values of the independent variable, which is the hours worked. In this case, it is reasonable to assume that Uan could work anywhere from 0 to 30 hours per week. Therefore, the domain is 0 to 30 hours.

The range represents the possible values of the dependent variable, which is the amount of money earned. Since Uan earns $11 per hour, working 0 hours would yield $0, and working the maximum of 30 hours would yield $330 (30 hours × $11 per hour). Thus, the range is $0 to $330.

The correct answer to the student's question, based on the information, would be: hours worked; amount of money earned; 0 to 30; $0 to $330.

The queen might've asked the king to measure the rug to demonstrate humility, responsibility, highlight practical skills, or grasp the concept of measurement. Without specific context, however, it's hard to pinpoint an exact reason.

Without specific context, it's difficult to provide an exact reason for the queen asking the king to measure a rug. However, in general, English literature often showcases rulers partaking in ordinary tasks as a means of demonstrating humility, responsibility, or attention to detail. For instance, the queen might have wanted the king to measure the rug in order to prove that he can attend to ordinary matters as well as royal duties, or perhaps to prove himself practical and not merely ceremonial. It could also be a ploy to make the king grasp the concept of measurement, size or area, by doing the task himself.

Answer:

The man got a 8% raise.

Step-by-step explanation:

Percentage change        = [Increase or decrease in value / Original Value]*100

Increase in hourly wage = [tex]13.5-12.5[/tex]

                                         =[tex]1[/tex]

Percentage raise             = [Increase in hourly wage / Initial hourly wage]*100

                                         =[tex]\frac{1}{12.5} *100[/tex]

                                         = [tex]8[/tex]%

The man got a 8% raise.

The man's hourly wage increased from $12.50 to $13.50 which, following the formula for calculating percentage change, indicates that he received an 8 percent raise in his hourly wage.

Given that the man's hourly wage increased from $12.50 to $13.50, we can use the formula for calculating the percentage change to find out what percent raise he got.

The formula for calculating the percentage change is as follows:

[(change in quantity)/(original quantity)] × 100

In this case, the change in quantity (the man's wage increase) is $1.00 (13.50 - 12.50), and the original quantity (the man's original wage) is $12.50.

Plugging these values into the formula, we get:

[1.00/12.50] × 100

This calculates to an 8 percent wage increase. Therefore, the man got an 8 percent raise in his hourly wage.

To complete the square for the equation x²-7x = 5, you need to add 12.25 to both sides of the equation, leading to the equation (x - 3.5)² = 17.25.

To complete the square in the equation x²-7x = 5, we will need to find a term (b) to add to both sides where b is one-half of the number being subtracted from x² (-7), squared.

First, we will take half of 7 which equals 3.5. Squaring 3.5, we get 12.25. Therefore, we add 12.25 on either side to complete the square.

The equation then becomes x² - 7x + 12.25 = 5 + 12.25, which simplifies to (x - 3.5)² = 17.25. This represents a completed square.
