Describe the similarity transformation that maps the preimage to the image. I need help with question 4

Answers

The coordinates of the vertices of the original shape are given to be:

[tex]\begin{gathered} L\Rightarrow(6,6) \\ M\Rightarrow(0,4) \\ N\Rightarrow(0,6) \end{gathered}[/tex]

The transformed shape coordinates are given to be:

[tex]\begin{gathered} L^{\prime}\Rightarrow(7,2) \\ M^{\prime}\Rightarrow(4,1) \\ N^{\prime}\Rightarrow(4,2) \end{gathered}[/tex]

On observation, the shapes show a dilation and a shift in position.

The image has a scale factor of 1/2, meaning it is reduced by 1/2. Therefore, the original coordinates will be reduced to give:

[tex]\begin{gathered} L^{\doubleprime}\Rightarrow\frac{1}{2}(6,6)=(3,3) \\ M^{\doubleprime}\Rightarrow\frac{1}{2}(0,4)=(0,2) \\ N^{\doubleprime}\Rightarrow(0,6)\Rightarrow(0,3) \end{gathered}[/tex]

The translation of the initial image can be gotten by subtracting the corresponding coordinates:

[tex]\begin{gathered} L^{\prime}-L^{\doubleprime}=(7-3,2-3)=4,-1 \\ M^{\prime}-M^{\doubleprime}=(4-0,1-2)=4,-1 \\ N^{\prime}-N^{\doubleprime}=(4-0,2-3)=4,-1 \end{gathered}[/tex]

All the differences are the same. This means that the image moves to the right by 4 units and down by 1 unit.

The dilation rule with a scale factor of k is given to be:

[tex](x,y)\to(kx,ky)[/tex]

The translation rule for a units to the right and b units down is given to be:

[tex](x,y)\to(x+a,y-b)[/tex]

Combining both rules, we have:

[tex](x,y)\to(kx+a,ky-b)[/tex]

Given:

[tex]\begin{gathered} k=\frac{1}{2} \\ a=4 \\ b=1 \end{gathered}[/tex]

Therefore, the transformation is given to be:

Ifthe width of the living room on the originalblueprint is 6 inches and the length is 9.6 inches,what are the scale and the width of the newblueprint?

Answers

Step 1

The original blueprint of the family has a scale of 2inches=5feet

The family wants to use a new blueprint that shows the length of the living room to be 15 inches.

Step 2

The width of the living room is

The width of the new print is;

[tex]\begin{gathered} \frac{6}{2}\times5=15feet \\ \frac{15}{8}\times5=9.375inches \end{gathered}[/tex]

Hence the scale of the new print is; 5inches = 8feet

Width of new blue print=9.375inches

Explain why a V-shaped graph does not represent a linear function.

Answers

A V-shaped graph belongs to an absolute value function or a piecewise function, never to a linear function (these are graphed only with a single line).

Why a V-shaped graph does not represent a linear function?

This is really trivial question.

A linear function has a graph that is a straight line.A V-shaped graph is not a straight line, is a V.

So the answer is really trivial, as you can see.

But let's explain it a little bit more.

The only functions that have V-shaped graphs are piecewise functions (formed of two linear equations) or absolute value equations, neither of these are exactly linear (but they are made of "linear like parts").

Answers

The sum of all interior angles of a triangle is 180° thus the measure of the exterior angle to ∠D is 126° so option (D) is correct.

 

What is a triangle?

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are 3 sides and three angles in every triangle, some of which may be the same.

It is known that the sum of all three angles inside a triangle will be 180°.

So,   m∠D +  m∠E +  m∠F = 180°

(3x + 27) + (4x + 22) + 68 = 180

7x + 49 + 68 = 180

7x = 63

x = 9

So,  m∠D = (3(9) + 27)° = 54°.

The exterior angle of D = 180- 54 = 126°.

Hence "The sum of all interior angles of a triangle is 180° thus the measure of the exterior angle to ∠D is 126°".

How many pounds of each kind of coffee should they mix? A) Write an equation using the information as it is given above that can be solved to answer the question. Use z as your variable to represent the quantity of Queen City coffee blend. Equation: 11.92 + 13.1. – 131 = 128.6 Х

Answers

The linear equations are x  +  y  =  10 and (11.90)x  +  (13.10)y  =  (12.86)(10) and the value of x and y are 2 and 8 respectively.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

A coffee distributor needs to mix a(n) Queen City coffee blend that normally sells for $11.90 per pound.

Let x and y be the quantity of Queen City coffee (lbs) and the quantity of Arabian Mocha coffee (lbs)

From the data given;

The equations can be framed:

x  +  y  =  10

(11.90)x  +  (13.10)y  =  (12.86)(10)

After solving the substitution method:

x = 2

y = 8

Thus, the linear equations are x  +  y  =  10 and (11.90)x  +  (13.10)y  =  (12.86)(10) and the value of x and y are 2 and 8 respectively.

At a school concert the total value of tickets sold was $3990. Student tickets sold for $8 and adult tickets sold for $11. The number of adult tickets sold was 6 less than 4 times the number of student tickets. Find the number of student tickets sold.

Answers

The number of student tickets sold is 78.

Given,

The number of student tickets sold = x

The number of adult tickets sold = 4x - 6

Total value of tickets sold = $3990

Value of one student ticket = $8

Value of one adult ticket = $11

Now, we have to find the number of student tickets sold:

Here,

The expression :8x + 11(4x - 6) = 3990

Solve the expression:

8x + 44x - 66 = 3990

52x - 66 = 3990

Add 66 to both sides

52x - 66 + 66 = 3990 + 66

We get,

52x = 4056

Divide 52 on both sides

52x / 52 = 4056/52

That is,

x = 78

Therefore,

The number of student tickets sold is 78.

From the given graph, we have 2 points with coordinates:

[tex]\begin{gathered} (x_1,y_1)=(1,2) \\ \text{and} \\ (x_2,y_2)=(4,1) \end{gathered}[/tex]

The equation of a line in slope-intercept form is given by

[tex]y=mx+b[/tex]

With the given points, we can find the slope m as follows:

[tex]\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ \text{then} \\ m=\frac{1-2}{4-1} \end{gathered}[/tex]

which gives

[tex]m=\frac{-1}{3}=-\frac{1}{3}[/tex]

Then, our line equation has the form

[tex]y=-\frac{1}{3}x+b[/tex]

Now, we can find the y-intercept b by substituting one of the two given points. For instance, if we substitute point (1,2) into the last result, we get

[tex]2=-\frac{1}{3}(1)+b[/tex]

which gives

[tex]\begin{gathered} 2=-\frac{1}{3}+b \\ \text{then} \\ 2+\frac{1}{3}=b \\ \frac{7}{3}=b \end{gathered}[/tex]

The two-way table shows the number of students that do or do not do chores at home and whether they receive an allowance or not. Allowance No Allowance Do Chores 13 3 Do Not Do Chores 5 4 a. How many total students do chores? b. What is the relative frequency of students that do chores and get an allowance to the number of students that do chores? Round to the nearest hundredth if necessary.

Answers

Given the table showing the number of students who do or do not perform chores, and who do or do not receive an allowance, we can add the numbers along the rows and columns, as shown in the diagram below:

Now, that we have summed the numbers along the vertical and horizontal directions, we can now proceed to answer the questions asked.

a.) The total number of students who do chores is equal to the horizontal sum of the numbers in the 'DO CHORES' row. This value is 16

Thus, 16 students do chores

b) The relative frequency of the students that do chores and get an allowance to the number of students that do chores is simply the ratio of the value in the cell that represents an intersection of the first 'DO CHORES' row, and the first 'ALLOWANCE' column, to the value that represents the sum of all the students that do chores ( i.e, the value at the end of the first row).

Thus, this is equal to = 13/16

Therefore, 13/16 is the relative frequency of the students that do chores and get an allowance to the number of students that do chores

c) The relative frequency of the students that do not do chores nor get an allowance to the total number of students, is simply the ratio of the value in the cell that represents an intersection of the second 'DO NOT DO CHORES' row, and the second 'NO ALLOWANCE' column, to the sum of the values in the last row or the last column.

Thus, this is equal to = 4/( 18 + 7) OR 4/(16 + 9) both of which is still 4/25

Therefore, 4/25 is the relative frequency of the students that do not do chores nor get an allowance to the total number of students.

d) The students who do not do chores are a total of 9

Of this 9, the number of students that do receive their allowance fall under the 'ALLOWANCE' column, and is equal to 5.

Therefore, expressed as a percentage of those who do not do their chores, the students who do not get an allowance are = (5/9) * 100 = 55% ( to the nearest whole number)

Thus 55% of students who do not do chores do not get an allowance

Lionfish are considered an invasive species, with an annual growth rate of 67%. A scientist estimates there are 8,000 lionfish in a certain bay after the first year.Write the explicit equation for f(n) that represents the number of lionfish in the bay after n years.

Answers

Answer:

f(n) = 8000(1.67)ⁿ⁻¹

Explanation:

The equation for exponential growth has the following form:

[tex]f(x)=a(1+r)^x[/tex]

Where a is the initial amount, r is the growth rate and x is the variable.

In this case, we know the amount after the first year and the growth rate and the variable is the number of years. So, replacing a by 8,000 and r by 0.67 and x by (n-1) because we will not include the 1st year, we get:

[tex]f(n)=8000(1+0.67)^{n-1}[/tex]

Therefore, the explicit equation for f(n) is:

[tex]f(n)=8000(1.67)^{n-1}[/tex]

1 A Great Way to Make Money POW ID: 965 High School, Discrete Math, Discrete Math Print Problem As your sixteenth birthday approaches you are looking for ways to make money so you can buy a used car. Currently, you earn $10 a week for doing chores around the house. Your father realizes that you are trying to save up, and offers you the following deal. You can either be paid the $10, or you can pull two bills from a brown paper bag. In the bag there are two $1 bills, two $5 bills, and a $10 bill. For example, you might pull out a $1 bill followed by a $5 bill, and earn only $6. Or you might pull out the $10 bill followed by a $5 bill and earn $15. If you were given this option every week, what would be better for you to do in the long run? Is pulling two bills from the paper bag a great way to make money?

Answers

The problem is about probability, so we need to know actually what is the probability of win more than $10 with the bag option, and see what is better in the long run. So we first are going to find

[tex]P(x>10)[/tex]

Where x is "the resultin money of pulling two bills from the paper bag", now

It's founder was Li Hongzhi, and his followers have been arrested, imprisoned, and tortured like they were common criminals. The reason for the suppression is because the Communist Party fears the strength and commitment of his followers. In 1999, over ten thousand practitioners peacefully gathered to protest a large amount of beatings and arrests in Tianjin, and the Communist Party responded by banning the practice of Falun Gong. Alot of brutal abuses have followed, including beatings, torture, and possibly even organ harvesting. Falun Gong composes five sets of meditation exercises to build character. Meditation effects the individual's qi, or chi, and Falun Gong shares some of the beliefs and practices of ancient Chinese medicine, Buddhism, and Daoism. Hopefully, violent suppression of the followers of Falun Gong will end as China comes under more constant global scrutiny for violations of human rights.Which option below is an acceptable revision of the underlined selection?Question 1 options:A uniqueA totally uniqueA quite uniqueNo revision is necessary.
