A parallelogram is transformed according to the rule (x, y) → (x, y). Which is another way to state the transformation?
R0, 90°
R0, 180°
R0, 270°
R0, 360°
Answer:- R(0, 360°) is the right answer.
Given: A parallelogram is transformed according to the rule (x, y) → (x, y).
⇒The points of the image is same as the points of the original figure.
⇒ The given mapping create an image onto itself.
We know that the mapping of all points of a figure in a plane is done by basic rigid transformations such as translation, reflection or rotation.
In rotation to create a image that is onto itself , then the rotation must be about 360°, so that the rotation will take a complete turn to get back the original figure with the same points.
Thus in rotation the another way to state the transformation is R(0, 360°).

The equations for two lines in the coordinate plane are 2dx - y = -4 and 4x - y = -6, where d represents an unknown value. What value(s) of d would make these lines perpendicular?
The value of d that makes the lines 2dx - y = -4 and 4x - y = -6 perpendicular is -1/8, as this value makes the product of their slopes equal to -1.
Explanation:To determine which value(s) of d would make the two lines perpendicular, we have to evaluate the slopes of the two lines and set their product to be -1, since perpendicular lines have slopes that are negative reciprocals of each other. Rearranging the first equation, 2dx - y = -4, we get y = 2dx + 4, which has a slope of 2d. For the second equation, 4x - y = -6, rearranging gives y = 4x + 6, with a slope of 4.
The product of the slopes of two perpendicular lines should be -1, so:
(2d) * 4 = -1
Solving for d: d = -1/8.
Thus, when the value of d is -1/8, the two lines are perpendicular.

Ingrid collected 6 cans of food and 18 boxes of food for the food bank. Which describes the relationship between cans of food and boxes of food?
The relationship between the cans of food and boxes of food that Ingrid collected can be determined by the mathematical equations involving addition/subtraction and multiplication/division.
For addition/subtraction:
D = x – y
Where D is difference, x is the number of cans of food, and y is the boxes. Substituting the known values,
D = 6 – 8 = -2
For multiplication/division:
R = x/y
Where R is the ratio. Substituting the known
values,
R = 6/8 = ¾ = 0.75
The relationship between the number of cans of food and boxes of food collected by Ingrid is a ratio of 1 can to 3 boxes after simplification. This means there is 1 can for every 3 boxes.
Ingrid collected 6 cans of food and 18 boxes of food for the food bank. To describe the relationship between cans of food and boxes of food, we can use a mathematical ratio.
The ratio of cans to boxes is calculated by dividing the number of cans by the number of boxes. This gives us:
6 cans : 18 boxes
To simplify this ratio, we divide both numbers by their greatest common divisor, which is 6:
6 ÷ 6 = 1
18 ÷ 6 = 3
Therefore, the simplified ratio is:
1 can : 3 boxes
This means there is 1 can of food for every 3 boxes of food. This ratio helps us understand the proportional relationship between the two quantities.
17.50 with a 7% sales tax?
To find the total cost of an item with sales tax, convert the tax rate to a decimal, multiply by the item's price, add the result to the original price, and round to the nearest cent. A $17.50 item with a 7% sales tax would cost a total of $18.73 after tax.
To calculate the total cost of an item with sales tax, you first need to determine the amount of sales tax by converting the percentage to a decimal and then multiplying by the item's cost. For an item priced at $17.50 with a 7% sales tax, you would convert 7% to a decimal (0.07) and then multiply this by $17.50. Therefore, the calculation would be:
Sales Tax = $17.50 x 0.07 = $1.225
Once you have the sales tax amount, you add it to the original price to find the total cost:
Total Cost = Original Price + Sales Tax
$17.50 + $1.225 = $18.725. After rounding to the nearest cent, the total cost would be $18.73.
what is 31 billion in scientific notation
we know that
[tex] 1 billion=1,000,000,000 [/tex]
In scientific notation
[tex] 1,000,000,000=1*10^{9} [/tex]
To find the value of [tex] 31 billion [/tex]
Multiply the value of one billion for [tex] 31 [/tex]
so
[tex] 31*1*10^{9} =31*10^{9}\\ =3.1*10^{10} [/tex]
therefore
the answer is
[tex] 3.1*10^{10} [/tex]
The scientific notation of [tex]31 \text{billion}[/tex] is [tex]\boxed{3.1 \times \left( {{{10}^{10}}} \right)}[/tex].
Further explanation:
Scientific notation is also called as the standard form of writing a number.
The number has two parts in the scientific notation.
First part is digits or digit with decimal and the second part is 10 to the power.
If the number is greater than 10, move the decimal point to the left.
If the number is less than 10, move the decimal point to the right.
Calculation:
One billion is equal to [tex]1000000000[/tex].
In scientific notation one million can be expressed as,
[tex]\boxed{{\text{1}}\,{\text{billion}} = {10^9}}[/tex]
Thirty one billion is equal to [tex]31000000000[/tex].
Now find the scientific notation SN of 31 billion.
[tex]\begin{aligned}\text{SN} &= 31000000000 \\&= 31 \times \left( {{{10}^9}} \right) \\&= 3.1 \times \left( {{{10}^{10}}} \right) \\ \end{aligned}[/tex]
The first part of the scientific notation is [tex]\boxed{3.1}[/tex].
The second part of the scientific notation is [tex]\boxed{{10^{10}}}[/tex].
Hence, the scientific notation of [tex]31 \text{billion}[/tex] is [tex]\boxed{3.1 \times \left( {{{10}^{10}}} \right)}[/tex].

B) 7 x 103 is twice as large as 2 x 103
C) 7 x 103 is 3 times larger than 2 x 103
D) 7 x 103 is 5 times larger than 2 x 103
The expression 7 x 10³ is 3.5 times larger than 2 x 10³ because the power of 10 is the same in both, so we simply compare the coefficients 7 and 2.
Explanation:The student is asking to compare two expressions written in scientific notation: 7 x 10³ and 2 x 10³. Scientific notation allows us to write very large or very small numbers conveniently and is commonly taught in middle school math.
To compare these two expressions, we can look at the coefficients (7 and 2) because the powers of 10 are the same in both expressions (10³). Since these powers are the same, comparing the coefficients directly will give us the relationship between the two expressions. Here, 7 is simply 3.5 times as large as 2, so we can say that 7 x 10³ is 3.5 times larger than 2 x 10³.
In terms of the answer choices provided by the student, we can thus conclude that the correct answer is:
A) 7 x 10³ is 3.5 times larger than 2 x 10³Which expression is equivalent to ? m-4/m+4 / (m+2)
Answer:
[tex]\frac{m - 4}{m + 4} / (m + 2)[/tex] is equivalent to [tex]\frac{(m - 4)}{(m + 4)(m + 2)}[/tex]
Step-by-step explanation:
Given Parameters;
(m-4)/(m+4) and (m+2)
Required:
To divide and write out the equivalent expression.
Two or more expressions are said to equivalent if and only if they give the same result.
Solving (m-4)/(m+4) divided by (m+2)
We have
[tex]\frac{m - 4}{m + 4}[/tex] divided by [tex]m + 2[/tex]
[tex]= \frac{m - 4}{m + 4} / (m + 2)[/tex]
Convert division to multiplication
[tex]= \frac{m - 4}{m + 4} *\frac{1}{(m + 2)}[/tex]
= [tex]\frac{(m - 4) * 1}{(m + 4) * (m + 2)}[/tex]
[tex]= \frac{(m - 4)}{(m + 4)(m + 2)}[/tex]
We can't simplify any further;
Hence, [tex]\frac{m - 4}{m + 4} / (m + 2)[/tex] is equivalent to [tex]\frac{(m - 4)}{(m + 4)(m + 2)}[/tex]
To check if this is true
Let m = 1
[tex]\frac{m - 4}{m + 4} / (m + 2)[/tex] becomes
[tex]\frac{1 - 4}{1 + 4} / (1 + 2)[/tex]
[tex]\frac{-3}{5} / (3)[/tex]
[tex]\frac{-3}{5} * \frac{1}{3}[/tex]
[tex]\frac{-1}{5}[/tex]
And
[tex]\frac{(m - 4)}{(m + 4)(m + 2)}[/tex] becomes
[tex]\frac{(1 - 4)}{(1 + 4)(1 + 2)}[/tex]
[tex]\frac{(-3)}{(5)(3)}[/tex]
[tex]\frac{-1}{5}[/tex]
Hence, [tex]\frac{m - 4}{m + 4} / (m + 2)[/tex] is equivalent to [tex]\frac{(m - 4)}{(m + 4)(m + 2)}[/tex]

Find the equation of a cosine curve that is obtained by shifting the graph of y=cos(x) to the left 5 units and upward 9 units and vertically compressed by a factor of 4 and vertically flipped
We want to find the equation of a cosine function after we apply some given transformations to it.
The equation of the resulting cosine curve is:
g(x) = -(1/4)*cos(x + 5) - 9/4.
Let's see how we got that equation:
First, we need to define all the transformations that we will be using:
Vertical shift:
For a given function f(x) a vertical shift of N units is written as:
g(x) = f(x) + N.
If N is positive the shift is upwards.IF N is negative the shift is downwards.Horizontal shift:
For a given function f(x) a horizontal shift is written as:
g(x) = f(x + N).
If N is positive the shift is towards the left.If N is negative the shift is towards the right.Vertical compression.
For a function f(x) a vertical compression by a factor k is written as:
g(x) = (1/k)*f(x).
Vertical flip (or vertical reflection).
For a general function f(x) a vertical reflection is written as:
g(x) = -f(x).
So we start with:
f(x) = cos(x).
First we shift it to the left 5 units, so we get:
g(x) = f(x + 5)
Then we shift it up 9 units, then we get:
g(x) = f(x + 5) + 9
Then we compress it vertically by a factor of 4:
g(x) = (1/4)*(f(x + 5) + 9)
Then we flip it vertically:
g(x) = -(1/4)*(f(x + 5) + 9)
Replacing f by the cosine function we get:
g(x) = -(1/4)*( cos(x + 5) + 9)
g(x) = -(1/4)*cos(x + 5) - 9/4.
This is the equation of the resulting cosine curve.

In professor shannon's economics class there are 12 male students. females represent 60% of the class total. how many students does professor shannon have in his economics class?
Answer:
There are total 30 students in the class.
Step-by-step explanation:
Let the total number of students in class = x
Number of males in the class = 12
Number of females in the class = 60% of Total students = 60% of x = 0.6x
So, we get that,
Number of males + Number of females = Total students
i.e. [tex]12+0.6x=x[/tex]
i.e. [tex]12=x-0.6x[/tex]
i.e. [tex]12=0.4x[/tex]
i.e. [tex]x=\frac{12}{0.4}[/tex]
i.e. x = 30
Thus, there are total 30 students in the class.

which series of transformations take the graph of f(x)=4x+9 to the graph of g(x)=-4x+7?
1. reflect the graph about the x axis and translate 2 units down?
2. reflect the graph about the y axis and translate 2 units up?
3. reflect the graph about the x axis and translate 2 units up?
4. reflect the graph about the y axis and translate 2 units down?
The correct transformation is to reflect the graph about the y-axis and then translate it 2 units down, corresponding to option 4.
The correct transformation is therefore to reflect the graph about the y-axis to change the slope from positive to negative and then translate 2 units down to change the y-intercept from +9 to +7. This corresponds to option 4 from the question.
