What kind of transformation is illustrated in this figure?
dilation
translation
reflection
rotation
Answer:
I would say it would be a translation transformation.
Step-by-step explanation:
Why would I say it would translation? Well, for starters; translation is the only one that would make sense (though, reflection could be the second best answer; but not the correct answer [explanation later]). Dilation doesn't make sense because it's not scaling from either bigger to smaller; from the picture. Translation makes sense because it goes from a different location, keeping its original state. As I said at the beginning, reflection could be the second best answer if it weren't for its mirroring action (it's reversed); making it not an available option for this question. Lastly, rotation definitely could not be correct because it's not rotating at all.
Therefore, translation would be the most viable option in this question.

What expressions are equivalent to the given expression
The value of the given expression is equivalent to [tex]y^{-5} x^{-2}[/tex], that is, option 5.
An exponent is a number or variable that is placed above and to the right of the expression to which it applies. It tells us the number of times the expression is used as a factor.
Here, we are given an expression as follows-
To simplify this expression we can use the following property of exponentials-
[tex]a^{l} a^{k} = a^{k+l}[/tex]
This holds true for all real values of a, k and l.
Thus, we can write the given expression as-
[tex]y^{-8} y^{3} x^{0} x^{-2} = y^{-8+3} x^{0-2}[/tex]
= [tex]y^{-5} x^{-2}[/tex]
Thus, the value of the given expression is equivalent to [tex]y^{-5} x^{-2}[/tex].
From the given options, thus, option number 5, is the correct answer.

is a proper subset different from a regular subset? is an empty set a proper subset? provide an example of a set for your classmates to solve for both a proper subset and an empty set. check and respond to the replies to your examples.
yes proper subset is different from a regular subset. The empty set is a proper subset of every set except for the empty set
A proper subset of a set A is a subset of A that cannot be equal to A. In other words, if B is a proper subset of A, then all elements of B are in A but A contains at least one element that is not in B.
Subset: If A and B are sets and every element of A is also an element of B, then:
A is a subset of B, denoted by A ⊆ B.
or equivalently, B is a superset of A, denoted by B ⊇ A.
Any set is considered to be a subset of itself. No set is a proper subset of itself. The empty set is a subset of every set. The empty set is a proper subset of every set except for the empty set.
For example, A = {1, 2, 3, 4, 5} and B = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}.
A = {1, 2, 3} and B = {1, 2, 3}
Here, A is a subset of B, or we can say that B is the superset of A.
Proper Subset: If A is a subset of B, but A is not equal to B (that is, there exists at least one element of B which is not an element of A), then
A is also a proper (or strict) subset of B; this is written as A ⊊ B.
For example A = {1, 2, 3} and B = {1, 2, 3, 4}.
Clearly, A is not equal to B and element {4} belongs to set B but is absent in set A, so we have one element in set B which is not an element of set A. Thus, A can be called a proper subset of B.
Hence, a proper subset of a set A is a subset of A that is not equal to A. In other words, if B is a proper subset of A, then all elements of B are in A but A contains at least one element that is not in B, thus the proper subset may or may not be the same.

2. The table shows the time it took for Javier to
complete one repetition of different
exercises during his Monday workout.
.
Exercise
Squats 0.08
Crunches 0.03
Lunges 0.04
Curts 0.05
Javier likes to work out for 1 hour. If he
doesn't use the full hour on his exercises, he
runs on a treadmill for the remaining time. If
he completed 3 repetitions of each exercise,
how long did he run on the treadmill on
Monday? I need explication step bu step
Using the addition of all the exercise, Javier runs on the treadmill on Monday is 0.40 hours.
What is addition?Addition is one of the mathematical operations. The addition of two numbers results in the total amount of the combined value.
Given that Javier completed 3 repetitions of each exercise. thus by multiplication time taken by Javier to complete each exercise is as follows;
Squats = 0.8 x 3= 0.24 hour
Crunches = 0.03 x 3 = 0.09 hour
Lunges = 0.04 x 3 = 0.12 hour
curls = 0.05 x 3 = 0.15 hour
we can calculate the total time taken to complete all exercises as;
0.24 + 0.09 + 0.12 + 0.15
= 0.60 hour
Now the time took on treadmill by Javier;
1 hour - 0.60 hour
0.40 hour
Hence, If he completed 3 repetitions of each exercise, then he run 0.40 hours on the treadmill on Monday.

The rational number equivalent to 1.28 bar over 28 is 1and 28 over 99 that is option 2) is correct
The number that we have been given is 1.28 bar over 28 that is 28 is repeating.
Now we have to convert it into simple fraction.
For we will first denote,
X = 1.28 bar over 28
Multiplying both side by 100 as two digits are being repeated we get,
100X = 128.2828…
Now subtracting it from X on both side s and putting the value of X we get
100X – X = 128.28… - 1.2828….
99X = 127
X =127/99
X = 1 28/99
Hence the rational number equivalent to 1.28 bar over 28 is 1and 28 over 99 that is option 2) is correct

Two hundred people hiked around the largest lake. About how many miles did they travel? Use the standard algorithm to solve. The largest lake is 15.33
Using proportions, it is found that they traveled a total of 3066 miles around the lake.
What is a proportion?A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using a rule of three, that can be either direct(cross multiplication) or inverse(line multiplication), deriving from proportional relationships.
One example of application of proportions is for unit rate problems, in which we find the unit rate for a single person, and then the total amount for a number n of people is given by n multiplied by the unit rate.
For this problem, we have that:
The largest lake has a distance of 15.33 miles.200 people hiked around the lake.Hence the total distance traveled by all these people is given as follows:

The expression [tex]-2\vec C+6\vec D[/tex] in the ordered pair notation is (16,-16).
The vector components of a vector are represented as the ordered pair of its x and y components.
For example, if a vector has x - component 'a' and y- component 'b' , then the ordered pair notation for the vector is (a, b), where the vector is [tex]a \vec i+b \vec j[/tex].
Now the vector C has its x- component = -2
y- component of C = -1
Therefore, ordered pair notation of C = (-2, -1)
x- component of D = 2
y-component of D = -3
Therefore, ordered pair notation of D = (2,-3)
So the expression [tex]-2\vec C+6\vec D[/tex] = -2 (-2,-1) +6 (2,-3) = (4,2) + (12, -18)

Step-by-step explanation:
You already know that TS = AB and TU = BC because it shows that in the images using the tick marks. SSS Triangle Congruence Postulate is when two triangles are congruent to each other because all the corresponding side lengths are equal to each other. So we already have two side lengths that are equal to each other, and, in order for SSS to be true, we need all 3 side lengths to be equal to each other. The only two side lengths not equal to each other yet are US and CA so if those were to be equal to each other, all corresponding side lengths would be equal to each other.

Jerald is having drain issues at his home and decides to call a plumber. The plumber charges $65 to come to his house and $55 for every hour they work. If the plumber charges Jerald a total of $296, how many hours did the plumber work? Write and solve an equation to determine the number of hours worked by the plumber.
A 55x − 65 = 296; x = 6.6 hours
B 55x + 65 = 296; x = 4.2 hours
C 65x − 55 = 296; x = 5.4 hours
D 65x + 55 = 296; x = 3.7 hours
Answer:
B 55x + 65 = 296; x = 4.2 hours
Step-by-step explanation:
The equation to determine the number of hours worked by the plumber is 65 + 55x = 296.
The number of hours worked by the plumber is 4.2
Option B is the correct answer.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
We have,
Charges for home visit = $65
Charges for each hour = $55
Let the number of hours = x
Total charges = $296
We can make an equation:
65 + 55x = 296
The number of hours can be calculated.
65 + 55x = 296
Subtracting 65 on both sides.
65 + 55x - 65 = 296 - 65
55x = 231
Dividing both sides by 55.
x = 231 / 55
x = 4.2
Thus,
The equation to determine the number of hours worked by the plumber is 65 + 55x = 296.
The number of hours worked by the plumber is 4.2
Option B is the correct answer.
