For the Transformation T, write the T^-1.
T : (x, y) (5x, 5y )
T^ -1 (x, y)
(x - 5, y - 5)
(5x - 1, 5y - 1)
(1/5x, 1/5y)
Answer: The correct option is
(C) [tex]T^{-1}(x,y)\rightarrow \left(\dfrac{1}{5}x,\dfrac{1}{5}y\right).[/tex]
Step-by-step explanation: We are given a transformation T defined as :
[tex]T:(x,y)\rightarrow (5x,5y).[/tex]
We are to find the inverse transformation [tex]T^{-1}(x,y).[/tex]
From the given transformation, we have
[tex]T:(x,y)\rightarrow (5x,5y)\\\\\Rightarrow T^{-1}(5x,5y)=(x,y).[/tex]
Let us consider that
[tex]5x=z~~~~~~\Rightarrow x=\dfrac{z}{5},\\\\\\5y=t~~~~~~\Rightarrow y=\dfrac{t}{5}.[/tex]
Therefore, we get
[tex]T^{-1}(5x,5y)\rightarrow(x,y)\\\\\Rightarrow T^{-1}(z,t)\rightarrow \left(\dfrac{z}{5},\dfrac{t}{5}\right)\\\\\\\Rightarrow T^{-1}(x,y)\rightarrow \left(\dfrac{1}{5}x,\dfrac{1}{5}y\right).[/tex]
Thus, (C) is the correct option.
The museum of science in boston estimated that 64% of all visitors came from within the state. on sunday, 2,500 people attended the museum. how many attended the museum from out of state?
First, calculate the number of attendees from within the state by multiplying the total by 64% to get 1,600 people. Subtract this from the total to find the number of out-of-state attendees, 900 people.
Explanation:This is a problem of percentage utilization and subtraction. First, we must determine the number of in-state attendees by multiplying the total number of attendees (2500 people) by the given percentage of in-state visitors (64%).
So, 2500 people x 0.64 = 1600 people.
These are the people who attended from within the state. To find out how many visitors came from out of state, we subtract this number from the total: 2500 people - 1600 people = 900 people. Therefore, 900 people attended the museum from out of state on Sunday.

Answer:
The answer is (3, 8)
Step-by-step explanation:
so next time you try to make a exponent use ^ exsample 3^9 3 to the power of 9 anyways since the x axis or sum is 3 it is y = 2^3 multiply it so 2 x 2 x 2 = 8 so that answer is (3, 8)

which do you think would seat more people a 4ft by 6 ft rectangular table or a circular table with a diameter of 6 ft? How many people would sit at each table? Explain your reasoning.
Final answer:
Comparing a 4ft by 6ft rectangular table and a circular table with a 6ft diameter, the circular table can seat more people (approximately 9) due to more efficient use of its perimeter, compared to the rectangular table which can seat 6 people.
Explanation:
The question asks which table would seat more people: a 4ft by 6ft rectangular table or a circular table with a diameter of 6ft. To answer this, we need to compare the arrangements and sizes of the two tables.
The rectangular table measures 4 feet by 6 feet. Typically, a person needs about 2 feet of space at a dining table to sit comfortably. Therefore, on the longer sides (6 feet), you can seat 3 people on each side, for a total of 6. On the shorter sides (4 feet), it's not practical to seat anyone due to space constraints and leg room. So, the rectangular table can seat 6 people.
The circular table has a diameter of 6 feet. Placing chairs around a circle often allows for more efficient use of space. If we assume each person requires the same 2 feet of space, roughly, the circumference of the table (which is π * diameter) dictates how many people can sit around it. The circumference of a 6-foot diameter table is about 18.85 feet (π * 6). Dividing this by 2 feet per person, you can seat approximately 9 people around the circular table.
In conclusion, a circular table with a diameter of 6 ft would seat more people, approximately 9, compared to a 4ft by 6ft rectangular table, which would seat 6 people. This is due to the circular table's ability to more efficiently use the perimeter for seating.

6s - 4 = 8 (2 + 1/4s)
To solve the equation 6s - 4 = 8 (2 + 1/4s), simplify and isolate the variable 's'. The solution is s = 5.
Explanation:To solve the equation 6s - 4 = 8 (2 + 1/4s), we need to simplify and isolate the variable 's'. First, distribute the 8 to both terms inside the parentheses:
6s - 4 = 16 + 2s
Next, move the variable terms to one side of the equation and the constant terms to the other side by subtracting 2s from both sides and adding 4 to both sides:
6s - 2s = 16 + 4
Combine like terms to simplify:
4s = 20
Finally, divide both sides by 4 to solve for 's':
s = 5

Maura is 5 years younger than her sister Cara. Seven years ago, Maura was half as old as her sister. How old is Maura now?
To solve this problem, set up equations based on the given information. M = C - 5 and M - 7 = (C - 7) / 2. Solve the system of equations to find Maura's age (19).
Explanation:To solve this problem, we can set up equations based on the given information. Let's let M represent Maura's age and C represent Cara's age.
The first clue tells us that Maura is 5 years younger than Cara, so we can write the equation M = C - 5.
The second clue tells us that seven years ago, Maura was half as old as Cara. So seven years ago, Maura's age was M - 7 and Cara's age was C - 7. We can write the equation M - 7 = (C - 7) / 2.
Now we can solve this system of equations to find Maura's age. Substituting the value of M from the first equation into the second equation, we get (C - 5) - 7 = (C - 7) / 2. Simplifying and solving for C, we find that Cara's current age is 24. Substituting this value back into the first equation, we find that Maura's current age is 19.
find the area of the circle .Leave your answer in terms of pie (3.14) the area is 4.1m .I need help on this question
Answer:
Area of the circle = 1.3π m²
Step-by-step explanation:
Area of the circle is given by the formula A = πr²
It is given that area of the circle is 4.1 m² and we have to convert it in the terms of π.
Now to convert the area in terms of π we will multiply the area by π and divide the area by 3.14.
⇒ Area×π / 3.14 = 4.1 × π/3.14 = 1.30π
Therefore answer is area of the circle = 1.30π m²
