In the same way that other functions can be combined, a series of transformations can be combined into a single function. For example,
this statement for the function S shows one way to represent the rotation of a point 270° counterclockwise about the origin followed by a
translation 3 units to the left and 1 unit up: S(270, 0)/<-3,1>(x, y) = (y - 3, -x + 1).
Write a function to represent each series of transformations:
• rotation of 90 degrees counterclockwise about the origin, point o, then a reflection across the x-axis
• reflection across the y-axis, then a translation a units to the right and b units up
• translation a units to the right and b units up, then a rotation of 180 degrees counterclockwise about the origin, then a reflection
across the y-axis
In geometry, transformations are used to move points from one position to another. The functions to represent the transformations are as follows:
[tex]S(90,0)/R_x(x,y) = (-y,-x)[/tex] .[tex]R_y/<a,b>(x,y) = (-x-a,y+b)[/tex].[tex]<a,b>(x,y)/S(180,0)/R_y = (x+a,-y-a)[/tex](a) Rotation of 90 degrees counterclockwise about the origin, point o, then a reflection across the x-axis
When a point is rotated [tex]90^o[/tex] counterclockwise, the rule is:
[tex](x,y) \to (-y,x)[/tex]
The rule of reflection across the x-axis is:
[tex](x,y) \to (x,-y)[/tex]
So, the combined transformation is:
[tex](-y,x) \to (-y,-x)[/tex]
Hence, the function that represents the transformation is:
[tex]S(90,0)/R_x(x,y) = (-y,-x)[/tex]
(b) Reflection across the y-axis, then a translation a units to the right and b units up
The rule of reflection across the y-axis is:
[tex](x,y) \to (-x,y)[/tex]
The rule of translation, a units right and b units up is:
[tex](x,y) \to (x + a,y+b)[/tex]
So, the combined transformation is:
[tex](-x,y) \to (-x - a,y+b)[/tex]
Hence, the function that represents the transformation is:
[tex]R_y/<a,b>(x,y) = (-x-a,y+b)[/tex]
(c) Translation a units to the right and b units up, then a rotation of 180 degrees counterclockwise about the origin, then a reflection across the y-axis
The rule of translation, a units right and b units up is:
[tex](x,y) \to (x + a,y+b)[/tex]
When a point is rotated [tex]180^o[/tex] counterclockwise, the rule is:
[tex](x,y) \to (-x,-y)[/tex]
The combined transformation at this point is:
[tex](x + a, y + a) \to (-x-a,-y-a)[/tex]
The rule of reflection across the y-axis is:
[tex](x,y) \to (-x,y)[/tex]
So, the overall transformation is:
[tex](-x-a,-y-a) \to (x+a,-y-a)[/tex]
Hence, the function that represents the transformation is:
[tex]<a,b>(x,y)/S(180,0)/R_y = (x+a,-y-a)[/tex]

Lauren wants to buy 3 shirts at $15.00 each. At home, she calculates the total cost as $46.20, using the sales tax rate of 8%. At the store, the cashier tells Lauren the total cost is $48.60. Who is wrong and what mistake did he or she make?
help!! please give explanation
9514 1404 393
Answer:
Lauren is wrong. She calculated tax on one shirt only.
Step-by-step explanation:
The cashier correctly determined the amount due to be ...
(3 × $15.00) × 1.08 = $48.60
Lauren correctly determined that the tax on one shirt is $15.00 × 0.08 = $1.20, but seemingly failed to realize that the tax on 3 shirts would be 3 times that amount. Lauren made a mistake in computing the tax due.

Which is better to buy? 3-yard roll of wrapping paper for $7.02. 8-foot roll of wrapping paper for $7.36
Answer:
3 yard roll of wrapping paper for $7.02 is better to buy.
Step-by-step explanation:
1 yard = 3 foot
3 yard = 9 foot
$7.02 / 9 foot = $0.78/foot
$7.36 / 8 foot = $0.92/foot
0.78 < 0.92
Therefore, 3 yard roll of wrapping paper for $7.02 is better to buy.

the sum of 88 elephants and x elephants is 145 elephants
Answer:
57 (if your solving for x)
Step-by-step explanation:
88 + x = 145
You subtract 88 from both sides
88 + x = 145
-88 -88
0 + x = 57
x = 57
A manager at a bus company wants to survey employees about the new uniforms. Which of the following best describes a stratified sample of employees?
a. The manager uses a computer program to draw 78 employees at random and selects these employees. Every set of 78 employees is equally likely to be drawn by the computer program.
b. The manager forms 6 groups of employees based on the departments the employees are in. Then, she selects 13 employees at random from each group.
c. The manager asks for volunteers and selects every volunteer until 78 employees are selected. She selects the volunteers because these employees are easily accessible.
At the beginning of the 20th century, they were built to compete against roads by offering greater road flexibility, and the further calculation can be defined as follows:
The software program in each collection of 78 workers would be likely to be drawn from the software. This kind of huge autonomous, wheeled car, usually on a fixed route, is used to transport passengers. The bus company management wants to look into the new uniforms for staff. The manager draws 78 people at random with such a computer program and selects those. The stratified sampling of employees can ideally be drawn from the set of 78 employees through the computer program.Following are the description of the wrong choice.
In option b, it is wrong because creating a group of employees is not good because after that we select the employee randomly.In option c it is wrong because in this question we select employees only.Therefore, "Option a" is correct.

Answer:
3 and 4 packagesStep-by-step explanation:
We need to find the LCM of 12 and 9.
9 = 3*312 = 2*2*3Their LCM is:
LCM(12, 9) = 2*2*3*3 = 36Number of light fixtures and light bulbs is 36.
Number of packages will be:
36/12 = 3 and36/9 = 4 respectively.Step-by-step explanation:
First finding LCM of 9 and 12
9 = 3 × 3
12 = 2 × 2 × 3
LCM = 3 × 2 × 2 × 3
LCM = 36
Now,
No. of light fixtures = 36/12 = 3
No. of light bulb = 48/12 = 4

Average rate of change please helpp
The average rate of change over the interval [-9, -3] is
[tex]\dfrac{f(-3) - f(-9)}{-3 - (-9)}[/tex]
That is, it's the ratio between the change in the function value over the length of the interval. Judging by the plot, we have f (-9) = 6 and f (-3) = -3. So the average rate of change is
[tex]\dfrac{f(-3) - f(-9)}{-3 - (-9)} = \dfrac{-3 - 6}{-3 + 9} = -\dfrac96 = \boxed{-\dfrac32}[/tex]

Find the y-intercept of the parabola y=x^2
Hello!
The y intercept of the parabola is when one of it's function's hits/intersects the y axis. The y intercept of the parabola y = x^2 is (0,0).
You may be wondering where is that, and why is it there. Y = x^2 is a parent function.
Check the image below for better explanation from me.
(0,0) = y - intercept
