Case 2: (x, y) → (- y, x)
Case 3: (x, y) → (- x, y)
Case 4: (x, y) → (- y, x)
Case 5: (x, y) → (x, - y)
Case 6: (x, y) → (x, y + 10)
How to determine the transformation rule for each case
In this question we find six cases of rigid transformations applied on figures. The most common rigid transformations are listed below:
Translation: (x, y) → (x + a, y + b), where a, b are real numbers.Reflection about x-axis: (x, y) → (x, - y)Reflection about y-axis: (x, y) → (- x, y) Rotation: (x, y) → (x · cos θ - y · sin θ, x · sin θ + y · cos θ), where θ is the angle of rotation.Then, by direct inspection, we derive the following rigid transformations:
Case 1 (Translation)
(x, y) → (x - 10, y + 9)
Case 2 (Rotation)
(x, y) → (x · cos (- 270°) - y · sin (- 270°), x · sin (- 270°) + y · cos (- 270°))
(x, y) → (- y, x)
Case 3 (Reflection about y-axis)
(x, y) → (- x, y)
Case 4 (Rotation)
(x, y) → (x · cos 90° - y · sin 90°, x · sin 90° + y · cos 90°)
(x, y) → (- y, x)
Case 5 (Reflection about x-axis)
(x, y) → (x, - y)
Case 6 (Translation)
(x, y) → (x, y + 10)

Write some examples of interval variables
An interval variable is a type of quantitative variable, where the difference between two values of the variable is meaningful and the values can be ordered.
Examples of interval variables include temperature (in Celsius or Fahrenheit), time (in seconds, minutes, hours, etc.), and dates. You can calculate the difference in temperature between two points, the length of time between two events, or the number of days between two dates. For example, let's say that the temperature outside is 25°C at noon and 29°C at 4 pm. The interval variable is the temperature, and the difference between the two temperatures is 4°C (29°C - 25°C = 4°C). Another example is the length of time between two events. Let's say that Event A began at 1 pm and Event B began at 2 pm. The interval variable is the length of time between the two events and the difference between the two times is 1 hour (2 pm - 1 pm = 1 hour). Finally, let's say that Date A is January 1, 2020 and Date B is January 10, 2020. The interval variable is the number of days between the two dates, and the difference between the two dates is 9 days (January 10,)An interval variable is a type of quantitative variable, where the difference between two values of the variable is meaningful and the values can be ordered.

Graph the linear system and tell how many solutions it has. If there is exactly one solution, estimate the solution and check it algebraically.
Answer:
There is exactly one solution: (3, 1)
Step-by-step explanation:
To graph these equations, you need to change them to slope intercept form:
x + y = 4 in slope intercept form is y = -x + 4 (subtract x frok both sides).
x - y = 2 in slope intercept form is y = x - 2 (subtract x from both sides then divide both sides by -1)*.
Now, all you have to do is graph both and find the point they cross at (the solution) which is (3, 1).
* = y can never be negative, which is why you divide by a -1 after subtracting x.

The angle of depression from the top of Pike’s Peak, at an altitude of 14,000 feet, to the city of Colorado Springs is 8o. The horizontal distance from the city to the peak is 58,000 feet. Find the altitude of Colorado Springs.
Answer:
[tex]\mbox{\large \boxed{\textsf{5, 849 \;feet}}}[/tex]
Step-by-step explanation:
See figure for information pertaining to this explanation
The figure is self explanatory
The triangle ABC forms a right triangle with the vertical leg of length 14000-h and horizontal length of 58000
The angle opposite side 14000 - h = 8°
By the tangent formula
[tex]\tan 8^\circ = \dfrac{AB}{AC} = \dfrac{14000-h}{58000}[/tex]
Switching sides,
[tex]\dfrac{14000-h}{58000} = \tan 8^\circ[/tex]
[tex]14,000 - h = 58,000 \times \tan 8^\circ\\\\14,000 - h = 8,151.36 \approx 8,151[/tex]
h = 14,000 - 8,151 = 5,849 feet
So the altitude of Colorado Springs is roughly 5,849 feet
This is close to the published value of 6,035 feet. The differences are due to estimate errors in horizontal distance, peak height and angle of depression

Allison was in an accident cause by her own negligence. She has 50/250 bodily injury insurance. There were 5 people injured in a mini-van and 2 people injured in Allison’s own car. The people injured in the accident sued and 4 were awarded $40,000, 2 were awarded $80,000 and 1 person was awarded $160,000. How much will the insurance company pay?
In this situation, Allison's insurance company will pay a total of $400,000.
Calculate the cost of insurance companyFirst, we need to add up the total amount awarded to the people injured in the accident. This is $40,000 x 4 + $80,000 x 2 + $160,000 x 1 = $400,000.
Next, we need to look at Allison's insurance policy. She has 50/250 bodily injury insurance, which means that the insurance company will pay up to $50,000 per person and up to $250,000 per accident.
Since the total amount awarded is $400,000, the insurance company will only pay the maximum amount allowed per accident, which is $250,000.
Therefore, the insurance company will pay $250,000 and Allison will be responsible for the remaining $150,000.

The solution to the radical equation is given as follows:
x = 1.
How to solve the radical equation?The radical equation for this problem is defined as follows:
1/x + (x - 1)/9x = 1.
To leave the left side with a common denominator, we can multiply 1/x by 9 in the numerator and in the denominator, hence:
9/9x + (x - 1)/9x = 1.
As the left side has a common denominator, we can add the numerators and keep the denominator constant, as follows:
(9 + x - 1)/9x = 1
(8 + x)/9x = 1.
Applying cross multiplication, the value of x is obtained as follows:
9x = 8 + x

The amount of money Company A charge more for x miles, 35 - 0.05x dollars
What is subtraction?In mathematics, subtraction is an operation which means taking away a few portions of the group or few things from a whole part.
For example, if we take 4 pencils out of 10 then remaining pencils are 6
so this process is called subtraction.
Let's call the number of miles the family wants to travel "x".
The cost for Company A is $30.50 plus 8 cents per mile, so the total cost for Company A is,
30.50 + 0.08x.
The cost for Company B is $65.50 plus 13 cents per mile, so the total cost for Company B is,
65.50 + 0.13x.
To find out how much more Company A charges, we can subtract the cost for Company B from the cost for Company A:
= (30.50 + 0.08x) - (65.50 + 0.13x)
= 35 - 0.05x
So, Company A charges 35 - 0.05x dollars more than Company B for x miles.

The budget for a project on voting trends includes $3200 for hiring undergraduate students, graduate students, and faculty members to conduct interviews on the day before an election. Each undergraduate student will conduct 30 interviews for $100. Each graduate student will conduct 32 interviews for $150. Each faculty member will conduct 33 interviews for $200. No more than 20 interviewers can be hired.
(a) How many of each type of interviewer should be hired in order to maximize the number of interviews?
(b) What is the maximum number of interviews?
To increase the number of interviews, it should be recommended that 0 undergraduate students, 16 graduate students, and 4 faculty members be hired. There can be a maximum of 644 interviews by statistics
Simplex Method:In 1947, George Dantzig invented an algorithm that allows us to take a system of equations and find its maximum or minimum values that make the equations most efficient. This method is used in linear programming to determine optimization.
If n = the number of interviews, then let x = the number of undergraduate students hired, y = the number of graduate students employed, z = the number of faculty members hired.
Maximization of n = 30x + 32y + 33z
The limitations are: x + y + z 20; 100x + 150y + 200z 3200; and 0;
The answer is 644 because x = 0, y = 16, z = 4.

Graph the linear system and tell how many solutions it has. If there is exactly one solution, estimate the solution and check it algebraically.
Answer: Infinite solutions.
Step-by-step explanation:
To graph both these equations, you need to make them slope intercept form (which is y = mx + b):
x + 2y = -2 in slope intercept form is y = -1/2x - 1 (subtract x from both sides then divide both sides by 2).
-3x - 6y = 6 in slope intercept form is y = -1/2x - 1. (add 3x to both sides then divide both sides by -6).
These are the same lines, so there are an infinite number of solutions when you graph.

Each marvel bag sold by Amy's marble company contains 7 red marbles for every 4 orange marble. If a bag has 28 orange marbles, home many red marbles does it contain
If a bag has 28 orange marbles, then it contain 49 red marbles.
What is ratio?A ratio is a comparison of two quantities or values, expressed in the form of a fraction or a division. Ratios are used to compare the size, magnitude, or quantity of two or more quantities or values.
For example, if there are 10 apples and 5 oranges, we can write the ratio of apples to oranges as 10:5 or 2:1, since there are two times as many apples as oranges. Similarly, if a recipe calls for 3 cups of flour and 1 cup of sugar, we can write the ratio of flour to sugar as 3:1, indicating that there are three times as much flour as sugar.
Ratios can be simplified, converted to equivalent fractions or decimals, or used to solve problems involving proportional relationships between different quantities. They are widely used in many areas of mathematics, science, and everyday life, such as in finance, engineering, and statistics.
According to given condition :We can start by using the given ratio of 7 red marbles for every 4 orange marbles to find the ratio of red marbles to orange marbles in the bag.
For every 4 orange marbles, there are 7 red marbles, so we can write:
7 red marbles / 4 orange marbles
We can simplify this ratio by dividing both the numerator and denominator by their greatest common factor, which is 1 in this case. This gives:
7/4
So the bag contains 7 red marbles for every 4 orange marbles.
If the bag has 28 orange marbles, we can use this ratio to find the number of red marbles in the bag. We can set up a proportion:
7/4 = x/28
where x is the number of red marbles in the bag.
To solve for x, we can cross-multiply:
7 × 28 = 4 × x
196 = 4x
Dividing both sides by 4, we get:
x = 49
Therefore, the bag contains 49 red marbles.
