Answer-
The sequences of transformations that maps △ABC to △A′B′C′ are
Reflection across the y-axisTranslation 2 units leftSolution-
The coordinates of the vertices of ΔABC are
A = (−4, 6)
B = (−2, 2)
C = (−6, 2)
The coordinates of the vertices of ΔA′B′C′ are
A′ = (2, 6)
B′ = (0, 2)
C′ = (4, 2)
As all the y-coordinates of all the function are same, so the triangle is neither translated up or down (∵ (x, y) → (x, y±k)), nor reflected over x-axis(∵ (x, y) → (x, -y)).
As the signs of x-coordinate is changed, it might be reflected over y axis,
Rule for reflection over y axis is,
(x, y) → (-x, y)
so,
A" = (4, 6)
B" = (2, 2)
C" = (6, 2)
As the x-coordinates of vertices of ΔA′B′C′ are 2 units less than that of ΔA"B"C"
So it is then translated 2 units left.
Therefore, the sequences of transformations that maps △ABC to △A′B′C′ are

If jay ran 1 mile in 5 minutes on monday, 2 miles in 10 minutes on tuesday, and 3 miles in 15 minutes on wednesday, how many miles do you think he might run in 20 minutes on thursday?
Answer:
Jay might run 4 miles in 20 minutes
Step-by-step explanation:
If Jay ran on Monday = 1 mile in 5 minutes
On Tuesday = 2 miles in 10 minutes
On Wednesday = 3 miles in 15 minutes
Jay is increasing his time by 5 minutes per day and distance 1 mile per day.
So the next day Jay might run 1 mile + previous day distance in 5 minutes + time of the previous day.
Therefore, Jay might run 4 miles in 20 minutes

A circle has its center at (-2, 5) and a radius of 4 units. What is the equation of the circle? (1 point)
(x + 2)2 + (y - 5)2 = 16
(x + 2)2 + (y + 5)2 = 16
(x + 2)2 + (y - 5)2 = 4
(x - 2)2 + (y + 5)2 = 4
Answer:
equation of circle (x +2)² + (x + 5)² = 16.
Step-by-step explanation:
Given : A circle has its center at (-2, 5) and a radius of 4 units.
To find : What is the equation of the circle.
Solution : We have given center at (-2, 5) and radius = 4 units .
Standard form of circle : (x -h)² + (x + k)² = r²
Where, ( h, k) is center , r = radius .
Plugging the values of h , k and r in standard equation
(x -(-2))² + (x + 5)² = (4)²
(x +2)² + (x + 5)² = 16.
Therefore, equation of circle (x +2)² + (x + 5)² = 16.

Choose all the sets containing the number Pi:
natural numbers
whole numbers
integers
rational numbers
irrational numbers
real numbers
Answer:
The set containing Pi is:
Irrational numbers.Real numbers.Step-by-step explanation:
We have to classify the number "pi" or π.
We know that:
Pi is the ratio of a circumference of a circle to it's diameter.
Pi is an irrational number i.e. it could not be represented in the form of p/q where p is an integer and q is a natural number.
However we sometimes take pi to be 22/7 ; but it's not exactly the same it's just a close approximation.
Hence, we may classify Pi as:
Irrational number.
Also irrational number comes in the category of real numbers.
Hence, Pi is also a real number.
( As real numbers are divided into two category:
1. Rational number
2. Irrational number
Also Rational number contains whole numbers, integers and whole numbers)
Using the number sets, the correct options are:
irrational numbers real numbers-------------------------------------
Whole numbers: Set of numbers including all positive numbers and 0, so: {0,1,2,...} Integer numbers: Number without decimals, that can be positive of negative, so: {...,-2,-1,0,1,2,....} Rational numbers: Integer plus decimals that can be represented by fractions, that is, they either have a pattern, or have a finite number of decimal digits, for example, 0, 2, 0,45(finite number of decimal digits), 0.3333(3 repeating is the pattern), 0.32344594459(4459 repeating is the pattern). Irrational numbers: Decimal numbers that are not represented by patterns, that is, for example, 0.1033430290339. Real numbers: Rational plus irrational.-------------------------------------
The number [tex]\pi = 3.1415...[/tex] is a decimal number without repetition, that is, it has infinite decimal places, thus it is irrational.Irrational numbers are also real.Thus, the correct options are irrational and real.A similar problem is given at https://brainly.com/question/10814303

Suppose that there are eight corporations competing for nine different contracts. If the contracts are awarded randomly, what is the probability that each corporation will get at least one contract?
To find the probability that each corporation will get at least one contract out of eight corporations competing for nine different contracts, we can use the concept of permutations and the principle of inclusion-exclusion.
Explanation:To find the probability that each corporation will get at least one contract, we can use the concept of permutations. Since there are 8 corporations and 9 contracts, we can calculate the total number of ways to assign the contracts to the corporations without any restrictions, which is 9! (9 factorial).
Next, we need to find the number of ways that each corporation gets at least one contract. This can be calculated using the principle of inclusion-exclusion. We subtract the number of ways that at least one corporation doesn't get a contract from the total number of permutations.
The number of ways that at least one corporation doesn't get a contract can be calculated by assigning 9 contracts to 7 corporations, which is 7! (7 factorial).
Finally, we can calculate the probability by dividing the number of ways that each corporation gets at least one contract by the total number of permutations:
Probability = (9! - 7!) / 9!

Write an inequality that describes this graph.
Please explain HOW you got your answer, thanks a ton! :)
Answer:
z ≤ 1
Step-by-step explanation:
We know the following:
If the initial point is colored, then the only possible inequality signs are ≤ or ≥. However, if the initial point is not colored, then the possible inequality signs for the inequality is < or >. If the line goes to the left of the initial point, it means that the initial point is greater than the numbers on the left of the initial point. If the line goes to the right of the initial point, it means that the initial point is less than the numbers on the right of the initial point.The inequality sign "≤" defines "less than or equal to"The inequality sign "≥" defines "greater than or equal to"The inequality sign "<" defines "greater than"The inequality sign ">" defines "less than"We can observe that:
In the inequality, we can see that the initial point of the inequality is colored. Therefore, the possible inequality signs for the inequality shown on graph are ≤ or ≥. Let us start setting our inequality.
⇒ _ ≤ or ≥ _We can see that the inequality line shown on the graph, goes to the left. Therefore, the line shown on the graph defines that the initial point is greater than the numbers on the left of the number line.
⇒ _ ≥ _Since "1" is the initial point and is greater than or equal to the numbers on the inequality, we can put "1" on the L.H.S of the inequality. Now,
⇒ 1 ≥ _[Optional] Write the numbers, that are less than 1, on the R.H.S of the inequality. Then, we get the following inequality:
⇒ 1 ≥ 0, -2, -4, -6...[Optional] Include "1" in the series as ≤ means greater than or equal to.
⇒ 1 ≥ 1, 0, -2, -4, -6...Let us assume that the numbers less than and equal to 1, be known as z.
⇒ 1 ≥ 1, 0, -2, -4, -6...⇒ 1 ≥ zTherefore, the inequality that represents the graph is z ≤ 1.
