Describe The Similarity Transformation That Maps The Preimage To The Image. I Need Help With Question

Answers

Answer 1

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:

[tex]\Rightarrow(\frac{1}{2}x+4,\frac{1}{2}y-1)[/tex]

patterns in proportional relationships, need help with the graph and the process table, i need to find a algebraic rule that represents the relationship between the number of pizzas, x, and the total cost, y.

Answers

Since the cost of each medium pizza is $7, then

Assume that the number of pizzas is x and the total cost is y, then

Multiply x by x to find y

The algebraic rule is

[tex]y=7x[/tex]

a) Let us complete the table

x: Process: y

0 0 x 7 = 0 0

1 1 x 7 = 7 7

2 2 x 7 = 14 14

3 3 x 7 = 21 21

4 4 x 7 = 28 28

a) We need to find the cost of 10 pizzas, then

Substitute x by 10 in the algebraic rule

[tex]\begin{gathered} y=7(10) \\ y=70 \end{gathered}[/tex]

The cost of the 10 pizzas is $70

b) If you have exactly $84, then substitute y by 84 to find x

[tex]\begin{gathered} y=84 \\ 84=7x \end{gathered}[/tex]

Divide both sides by 7 to find x

[tex]\begin{gathered} \frac{84}{7}=\frac{7x}{7} \\ 12=x \end{gathered}[/tex]

You can buy 12 pizzas buy $84

c) If you buy 0 pizza, then the cost of it is

[tex]\begin{gathered} x=0 \\ y=7(0) \\ y=0 \end{gathered}[/tex]

Since zero multiplied by any number give zero

The cost of zero pizza is zero

Because 0 x $7 = $0

Step-by-step explanation:

Plug in the height into the equation: h(t)=144-16t^2

Solve for t.

Ex:

128=144-16t^2, subtract 144 on both sides

-16=-16t^2, divide -16 on both sides

How to solve variable related problems?

1. Switch the positions of the variables in the equation. Starting with "solving for x" (or any other variable) in one of the equations, this "substitution" approach begins. [2] Say your equations are, respectively, 4x + 2y = 8 and 5x + 3y = 9.

2. To "solve for x," divide both sides of the equation.

3. Reconnect this to the other equation. Don't use the equation you just employed; rather, return to the other one.

When a particular variable's value is given to you

we just have to substitute that value in the required equation.

Find the point-slope form of the equation given: g(5) = 10 and g(2) = 8

Answers

Answer:

[tex]y -10=\cfrac{2}{3} (x -5 )[/tex]

========================

Given

Two points: (5, 10) and (2, 8)

To find

The point-slope form of the equation representing this line

Solution

Point-slope form is:

[tex]y -y_1=m(x - x_1)[/tex], where (x₁, y₁) is one of the points and m is the slope

Find the slope:

[tex]m=\cfrac{y_2-y_1}{x_2-x_1} =\cfrac{8-10}{2-5} =\cfrac{-2}{-3} =\cfrac{2}{3}[/tex]

Use one of the points and the slope to determine the equation of the line:

[tex]y -y_1=m(x - x_1)[/tex], substitute the slope and [tex]y -10=\cfrac{2}{3} (x -5 )[/tex]

Answer:

[tex]y-10=\frac{2}{3} (x-5)[/tex]

Step-by-step explanation:

Pre-Solving

We are given: g(5)=10, and g(2)=8.

The value inside the parentheses is the x value, and the value that it (g(x)) is equal to is the y value.

So, as points, the values are (5, 10), and (2, 8).

The equation wants to be written in point-slope form, which is [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is a point.

Solving Slope

We first want to find the slope of the line.

The slope (m) can be found with two points using the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points.

We can label the values of the points we were given.

[tex]x_1=5\\y_1=10\\x_2=2\\y_2=8[/tex]

Now, substitute these values into the formula.

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{8-10}{2-5}[/tex]

Subtract.

[tex]m=\frac{-2}{-3}[/tex]

Simplify.

[tex]m=\frac{2}{3}[/tex]

The slope is 2/3.

Since we now have the value of the slope, as well as [tex](x_1, y_1)[/tex], we can plug these values into the formula for point-slope form.

Point-Slope Form

Recall that [tex]x_1=5[/tex] and [tex]y_1=10[/tex]; plug these in for [tex]x_1[/tex] and [tex]y_1[/tex] respectively.

[tex]y-10=m(x-5)[/tex]

We also just found the slope, which is 2/3. Plug that in for m.

[tex]y-10=\frac{2}{3} (x-5)[/tex]

A political gathering in South America was attended by 8,475 people. Each of South America's 12 countries and 3 territories was equally represented. How many representatives attended from each country?​

Answers

There were 707 representatives who attended political gatherings from each country in South America.

We have been given that a political gathering in South America was attended by 8,475 people.

Each of South America's 12 countries and 3 territories were equally represented.

The number of representatives attended from each country is the ratio of the total number of people in the gathering to the total number of countries.

The number of representatives :

⇒ total number of people in the gathering /  total number of countries

The number of representatives = 8,475 / 12

The number of representatives = 706.25 ≈ 707

Hence, there were 707 representatives who attended political gatherings from each country.

Using the properties of parallel lines we find the value of x is 9 and the value of y is 13.

In geometry, parallel lines are coplanar, straight lines that never intersect.

Any parallel planes in the same three-dimensional space are those that never intersect. Parallel curves are those that have a predetermined minimum separation between them and do not touch or intersect. If a line and a plane in three-dimensional Euclidean space do not intersect at a point, they are also said to be parallel. On the other hand, skew lines are two noncoplanar lines. A transversal is a line that crosses across two other lines in the same plane at two separate points. Transversals play a crucial role in establishing if two or more other lines in the Euclidean plane are parallel.

15). In the given figure the two angles represented by 12x+1 and 15x -26 are equal. as they are alternate exterior angles.

We know from the property of parallel lines that they are equal.

Therefore:

12x+1 = 15x -26

or, 12x-15x = -26-1

or, -3x = -27

or, x = 9

Therefore the angles are 12x + 1 = 109

Now,

109 + 4y-9 +28 =180

or, 4y = 180 - 128

or, y = 13.

Therefore as the line l and m are parallel the value of x is 9 and the value of y is 13 .

Linear function and transformation

A linear function is defined according to the following rule:

y = mx + b.

In which:

m is the slope of the function, which is by how much y changes by when x changes by 1.b is the intercept of the function, which is the value of y when x = 0.

From the stated graph, we have that when x = 0 and y = 6, and when x increases by 1, y decays by 2, hence the function is defined as follows:

y = -2x + 6.

The parent function is:

f(x) = x.

Then, to generate the transformed function, we have that:

x -> -x, hence the function was reflected over any of the axis.-x -> -2x, hence there was a vertical stretch by a factor of 2.-2x -> -2x + 6, meaning that the function was shifted up 6 units.

Using these three bullet points, the correct options were chosen.

When you reverse the digits, you have xy.

The value of the new number is

10x + y

"If the digits are reversed, the new number is the sum of twice the original number and seven."

10x + y = 2(10y + x) + 7      Equation 2

We have a system of 2 equations.

x - y = 5

10x + y = 2(10y + x) + 7

Simplify the second equation.

10x + y = 2(10y + x) + 7

10x + y = 20y + 2x + 7

8x - 19y = 7

x - y = 5

8x - 19y = 7

Solve the first equation for x. Substitute that value for x in the second equation.

x = 5 + y

8(5 + y) - 19y = 7

40 + 8y - 19y = 7

-11y = -33

y = 3

x = 5 + y

x = 5 + 3

x = 8

The digits are:

ones digit: 8

tens digit: 3

The number is 38.

Answer:

9 and 1 respectively

Step-by-step explanation:

|2(-3)-5| = |-9| = 9

|2(2)-5| = |1| = 1

the vertical lines represents absolute value, this just mean that any negative values are then turned into their positive counterparts.

What is the area of the triangle shown below?131310units2

Answers

SOLUTION

We want to find the area of the triangle in the image.

To do this, we will make use of the Heroes formula which states

[tex]\begin{gathered} A=\sqrt{s(s-a)(s-b)(s-c)} \\ where\text{ s =}\frac{a+b+c}{2} \\ a,b\text{ and c are the sides of the triangle } \end{gathered}[/tex]

applying this, we have

[tex]\begin{gathered} s=\frac{13+13+10}{2} \\ s=\frac{36}{2} \\ s=18 \end{gathered}[/tex]

The area A becomes

[tex]\begin{gathered} A=\sqrt{18(18-13)(18-13)(18-10)} \\ =\sqrt{18\times5\times5\times8} \\ =\sqrt{3,600} \\ =60\text{ units}^2 \end{gathered}[/tex]

Hence the answer is 60 square units

When she finally emerged from underground, she got to the sidewalk and looked at the landscape. She was used to flatness and green; the farm that theyd just sold had cattle grazing as far as the eye could see. There was nothing green in sight here as cement behemoths sprung out of the ground taller than the stalks of corn back in Iowa. People zipped in front of her with briefcases tucked to their sides as high heels clacked on the pavement. It was all so overwhelming, so loud, and Hattie put her hands over her ears to shut out the sounds of the taxi horns and the thousand different conversations. Her little sister Evelyn didnt; she was trying to take it all in.Her mother pulled out a map from her purse and held it in shaky hands. According to this, our new home should be right here. Hattie traced her mothers index finger to a building that was so high that she had to crane her neck to see the top.This? Evelyn gasped.Her father, the man who was never at a loss for words, didnt say anything. He adjusted the weight of the three bags that contained most of the possessions theyd been able to bring on the three-hour plane journey that had uprooted them from their old lives and deposited them in New York City.Her father struggled to open the heavy front door, and when they were inside, the smell of hundreds of different meals clashed in her nose: spaghetti, fried chicken, fish, and curry. They stood in front of a bank of elevators as Evelyn pushed the button for the seventeenth floor. When they entered what would be their new home, Hattie spun around in tiny circles as her father gave them the grand tour.Here is where you and Evelyn will sleep, he announced. He pointed to a room that was half the size of the Iowa bedroom that was hers alone, the same Iowa bedroom where shed had all her sleepovers and whose walls still showcased the crayon scribbles from when she was a toddler. Shed tried to scrub them clean, but they were more stubborn than she was, so they would be there for the new family that would be moving in soon.Evelyn tried to sound excited. We get to share a room!Hattie was grateful for her younger sister, for the way that she could always look at the bright side of things. Hattie couldnt say anything in responseshed been speechless for most of the trip. Instead, she followed her father down the hallway that was narrow enough for one person to fit through, maybe two if they squeezed shoulder to shoulder.And here is where your mom and I will be. She could hear the forced excitement in her fathers voice for a move that he didnt want to make either. But theyd had to sell the farm, and when this opportunity presented itself, there had really been no choice.The tour was over as soon as it startedtiny kitchen, one bathroom, boxy living room. The four of them would be sharing an apartment that was smaller than the drafty old kitchen in the farmhouse.Without a word, they grabbed boxes and started about the business of unpacking in rooms that were inches away from one another rather than feet. Hattie walked over to a dirty square window in her new shared bedroom. She wiped it clean, hoping to see something that would remind her of Iowa, but the window only looked out onto more concrete and glass. A wave of sadness washed over herthe first crack in the numbness that shed been feeling for the past month since she found out about the move. She turned her back and lowered her head so Evelyn wouldnt see her, but then the sobs came, each louder than the previous one.There was a hand on her shoulder. She wanted to put the smile back on because she knew it would be better for Evelyn and everyone else that way, but she couldnt summon it now. She turned around and saw her blurry sister through tear-filled eyes. In front of her face, Evelyn was holding a folded-up picture of the whole family in front of the farmhouse.I miss it too, Evelyn began, but we dont have to forget it.Together, they taped the picture to the corner of the bedroom window so they could see it whenever they wanted. Hattie pulled Evelyn close, knowing that a place would never be as important as the people in it. An architect is designing a gazebo which base is a regular dodecagon.
