Answer:
D. Stretch
Step-by-step explanation:
All the others keep the same dimensions
The one which is not a rigid motion transformation is D. Stretch.
What is Geometric Transformation?Transformation of geometrical figures or points is the manipulation of a given figure to some other way.
Different types of transformations are Rotation, Reflection, Glide reflection, Translation and Dilation.
Rigid motion transformation is the transformation which is formed when a point or a shape is transformed such that the size or the shape of the original object does not change.
In rotation, translation and reflection, there is no change in the size or the shape.
But in dilation, the size becomes smaller or larger based on it is enlargement or stretch.
So stretch is not a rigid motion transformation.
Hence option D is the correct answer.

The true statement for the Pentagon in the given graph is
The scale factor of the dilation is 1/2 with the center at the origin(0,0).
Dilation:Dilation implies resize of any object.
It may increase or decrease the object by a particular value.The particular value is called the scale factor. Properties of Dilation of figure:Parallel lines in the dilated figure remain the same as in the original figure.The dilation of any figure does not vary from each angle of the figure.The midpoints of the dilated figure remain the same as that of the original figure.True statement:The scale factor of the dilation of the pentagon is 1/2.
Reason:The pentagon with vertices A(0.5,4.5), B(2,3), C(1,0), D(-2,0), E(-3,3) when multiplied by 1/2 we get The vertices of the dilated pentagon as A'(0.25,2.25), B'(1,1.5), C'(0.5,0), D'(-1,0), E(-1.5,1.5). When we plot the points A'B'C'D'E' in the graph, obtain the dilated pentagon with a center at the origin. Wrong statement with Reasons:The scale factor of the dilation is not 1/4 because when we multiply the vertices of pentagon ABCDE by 1/4 we are not getting the dilated points as in the graph.The line EA is parallel to E'A' but,1. The line EA does not passes through the center of the dilation
at origin(0,0), which can be clearly seen from the given graph.
2. For two lines to be parallel it is not necessary for one of the
lines to pass through the origin.
The line C'D' is parallel to CD as we should see the figure in a 3-dimensional way and it also follows the properties of dilation of a figure.Hence the scale factor of the given pentagon is 1/2.

Which of the following is the function of f(x)?
Answers
Answer:
f(x) = 8(x-3)
Step-by-step explanation:
F^ -1 ( x) = x/8 +3
Let y = x/8+3
To find the inverse
Exchange x and y
x = y/8+3
Solve for y
x-3 = y/8+3-3
x-3 = y/8
Multiply each side by 8
8(x-3) = y/8 * 8
8(x-3) = y
The inverse of the inverse is the function so
f(x) = 8(x-3)
Answer:
[tex]\boxed{f(x) = 8(x-3)}[/tex]
Step-by-step explanation:
[tex]y=\frac{x}{8} +3[/tex]
Switch variables.
[tex]x=\frac{y}{8} +3[/tex]
Make y as subject.
Subtract 3 from both sides.
[tex]x-3=\frac{y}{8}[/tex]
Multiply both sides by 8.

Shelley and David have a sweet tooth. Shelley spent \$2.65 for 15 sour keys and 2 chocolate bars. David bought 3 chocolate bars and 10 sour keys for \$3.35 at the same store. Find the cost of each chocolate bar and each sour key at this store. If you need 8 chocolate bars and 24 sour keys to give to friends coming to your birthday party, how much will they cost you at this store?
Answers
Answer:
Chocolate bars: $0.95 each
Sour keys: $0.05 each
Total cost for 8 chocolate bars and 24 sour keys: $8.80
Step-by-step explanation:
sour keys=x
chocolate bars=y
15x+2y=2.65
10x+3y=3.35
multiply the second equation by 1.5
15x+4.5y=5.025
2.5y=2.375
y=0.95
Chocolate bars are $0.95 each.
Now substitute the y value in one of the equations
15x+2(0.95)=2.65
15x+1.9=2.65
15x=0.75
x=0.05
Sour keys are $0.05 each.
For the second part of the question, just multiply the number of chocolate bars by the cost and same thing with the sour keys and add them.

HELP URGENT PLEASE! The Lees have purchased a new home for $360,000, and put a down payment of $50,000 on it. They have a mortgage for the balance, amortized over 20 years at 5.25%. If the Lees pay off the mortgage at the end of the 20 years, how much interest will they have paid in total? USE TVM SOLVER
Answers
Answer:
$191,340.80
Step-by-step explanation:
Step 1
We find the amount that is paid monthly by the Lee's
We are told in the question that:
Cost of the house =$360,000
Down payment = $50,000
We are also told, the balance left after the down payment was made = Mortgage that is amortized at an
Interest rate of 5.25%
Time = 20 years
Hence, Mortgage amount = $360,000 - $50,000 = $310,000
Formula for monthly payment =
M= P[r(1+r)^n/((1+r)^n)-1)]
M = the total monthly mortgage payment.
P = the principal loan amount.
r = your monthly interest rate.
= rate/12
=5.25%/12 = 0.0525/12
= 0.004375
n = number of payments
= number of years × number of months
= 20 × 12 = 240 payments
Formula for monthly payment =
M= P[r(1+r)^n/((1+r)^n)-1)]
M = 310,000[0.004375(1 + 0.004375)^240/((1 + 0.004375)^240 ) - 1]
M = $2,088.92
Therefore, the monthly payment by the Lee's is $2,088.92
Step 2
We calculate the Total Amount paid by the Lee's in 20years because we are told in the question that they paid off their mortgage after 20 years
Total Amount paid = Monthly payments × Number of payments
= $2,088.92 × 240
= $501,340.80
Step 3
The third and final step is to calculate the Total interest paid for 20 years
Total Interest = Total amount paid - Mortgage amount
= $501,340.80 - $310,000
Total Interest: $191,340.80
Therefore,the interest will they have paid in total is $191,340.80
The vertex of the parabola below is at the point (-3, -5). which of the equations below could be the one for this parabola?
A. x = -3(y + 5)^2
B. y = (x + 3)^2 -5
C. y = (x - 5)^2 + 3
D. y = (x + 3)^2 + 5
Answers
Answer:
Step-by-step explanation:
The coordinates of a vertex are (h, k). If our vertex is (-3, -5), then h = -3 and k = -5. The vertex form of a parabola is
[tex]y=(x-h)^2+k[/tex] so if we fill in our h and k values, the equation becomes

On a coordinate plane, a piecewise function has 3 lines. The graph shows cleaning time in hours on the x-axis and total cost in dollars on the y-axis. The first line has an open circle at (0, 50) and continues horizontally to a closed circle at (2, 50). The second line has an open circle at (2, 100) and continues horizontally to a closed circle at (6, 100). The third line has an open circle at (6, 200) and continues horizontally to a closed circle at (8, 200). The graph represents the cleaning costs charged by a housekeeping service. Which statement is true of the cost function? A cleaning time of 2 hours will cost $100. A cleaning time of 6 hours will cost $150. Cost is a fixed rate of $100 for jobs requiring more than 2 hours, up to a maximum of 6 hours. Cost is a fixed rate of $200 for jobs that require at least 6 hours.
Answers
Answer:

Step-by-step explanation:
Let's consider each of these statements in view of the graph:
A cleaning time of 2 hours will cost $100. -- The closed circle at (2, 50) tells you the cost of a 2-hour job is $50, not $100.A cleaning time of 6 hours will cost $150. -- The closed circle at (6, 100) tells you the cost of a 6-hour job is $100, not $150.Cost is a fixed rate of $100 for jobs requiring more than 2 hours, up to a maximum of 6 hours. -- The line between the open circle at (2, 100) and the closed circle at (6, 100) tells you this is TRUE.Cost is a fixed rate of $200 for jobs that require at least 6 hours. -- "At least 6 hours" means "greater than or equal to 6 hours." The closed circle at (6, 100) means a 6-hour job is $100, not $200.Answer:

Devi’s mother is three times as old as Devi. Five years ago, Devi’s mother was four times as old as Devi was then. Find their present ages
Answers
Answer:
Devi's present age = 15 years
Devi's Mother's present age = 45 years
Step-by-step explanation:
Let the present age of Devi be x years.
Therefore, mother's present age = 3x
Five years ago:
Devi's age = (x - 5) years
Mother's age =( 3x - 5) years
According to the given condition:
Five years ago:
Devi's mother's age = 4 times Devi's age
3x - 5 = 4( x - 5)
3x - 5 = 4x - 20
20 - 5 = 4x - 3x
15 = x
x = 15 years
3x = 3* 15 = 45 years
Hence,
Devi's present age = 15 years
Devi's Mother's present age = 45 years

A wise old owl climbed up a tree whose height was exactly ninety plus three. Every day the owl climbed up 18 and every night climbed down 15. On what day did the owl reach the top of the tree?
Answers
Answer:
He reached the top of the tree on the 31st day
Step-by-step explanation:
The total distance for the owl to climb is 93 units.
If the owl climbed 18 units up the tree every day without coming down, the owl would have taken 93/18 days to reach the top of the tree.
However, the owl descends by 15 units every night. This just reduces the overall distance covered at the end of each day's climb.
The net distance covered by the owl after each day is 18-15 units = 3 units of climb. This is the steady distance the owl gains up the three at the end of each day after the ascent and descent.
The time taken for the climb moving at this pace of 3 units per day will be
93 units / 3 units per day = 31 days

monthly payment = $227.30
__
Her total of 24 payments will be ...
total repaid = 24 × $227.30 = $5,445.20

Find the probability that a record player will last less than 2 years?
Answer:
the probability that a record player will last less than 2 years is 0.1586
Step-by-step explanation:
Given that:
A mean which is normally distributed = 3
and a standard deviation = 1
The objective is to find that a record player will last less than 2 years
Let X be the random variable
i.e
[tex]P(X<2) = P( \dfrac{X - \mu}{\sigma}<\dfrac{X - \mu}{\sigma})[/tex]
[tex]P(X<2) = P( \dfrac{2 - \mu}{\sigma}<\dfrac{2 - 3}{1})[/tex]
[tex]P(X<2) = P( Z< \dfrac{-1}{1})[/tex]
[tex]P(X<2) = P( Z< -1)[/tex]
From the standard normal tables :
[tex]P(X<2) = 1- P( Z< 1)[/tex]
[tex]P(X<2) = 1- 0.8414[/tex]
P(X < 2) = 0.1586
Therefore; the probability that a record player will last less than 2 years is 0.1586
