A permutation of a set in mathematics is, broadly speaking, the rearrangement of its elements if the set already has an ordered structure into a sequence or linear order. The act or procedure of altering the linear order of an ordered set is referred to as a "permutation."
A permutation is a function that rearranges a set; it is not an arrangement in and of itself. It is a bijection from a set to itself. Permutations are the arrangements themselves, according to an older and more fundamental perspective. The terms active and passive are occasionally attached to the term permutation to distinguish between these two, but older terminology uses the terms replacements and permutations.

the length of each side of a square is 3 inches more than the length of each side of a smaller square. the sum of the areas of the squares is 149 inches squared. find the length of the side of the smaller square.
The length of the side of the smaller square is 7 inches.
Let x be the length of the side of the smaller square.
The length of each side of a square is 3 inches more than the length of each side of a smaller square. Thus the length of the side of the larger square is
(x + 3) inches.
The area of the smaller square is
x^2 square inches.
The area of the larger square is
(x + 3)^2 square inches.
We can set up the equation:
x^2 + (x + 3)^2 = 149
Expanding and simplifying the equation gives:
x^2 + x^2 + 6x + 9 = 149
Combining like terms:
2x^2 + 6x - 140 = 0
Using the quadratic formula, we can solve for x:
x = (-b ± √(b^2 - 4ac)) / 2a
x = (-6 ± √(6^2 - 4 * 2 * (-140))) / 2 * 2
x = (-6 ± √(36 + 1120)) / 4
x = (-6 ± √(1156)) / 4
x = (-6 ± √(596)) / 4
x = (-6 ± 34) / 4
x = -10 or x = 7
The side length of the smaller square can't be negative, so x = 7 inches.

Determine whether each function has a constant or variable rate of change. Use rates of change to determine whether each function is linear or nonlinear. answer
We can also check if the function's equation is in the form y = mx + b.
What is function's equation ?
A function's equation is a mathematical statement that defines the relation between the input (also known as independent variable) and output (also known as dependent variable) of a function. The equation is typically represented by the letter "y" for the output, and one or more letters for the input (usually "x").
To determine whether a function has a constant or variable rate of change, we need to find the slope or rate of change between two points on the function. If the slope remains the same no matter what two points we choose, the function has a constant rate of change and is linear. If the slope changes depending on the two points we choose, the function has a variable rate of change and is nonlinear.
To determine whether a function is linear or nonlinear, we can also check if the function's equation is in the form y = mx + b, where m and b are constants. If it is, the function is linear, otherwise it is nonlinear.
It's important to mention that, in order to have a definitive answer, we need the function to be defined.
We can also check if the function's equation is in the form y = mx + b.

Otis wants to borrow 10000 to buy a used car. he examined his budget and decided that he can afford a payment of $200 a month. if his bank offers him a rate of 7.5%, how long should he borrow the money so he can afford his monthly payment?
Answer: Otis should borrow the money for 60 months (5 years) so he can afford his monthly payment of $200.
Step-by-step explanation: To calculate the duration of the loan, we can use the formula:
Duration (in months) = Loan amount / Monthly payment
In this case, the loan amount is $10,000, and the monthly payment is $200. So by substituting the values, we get:
Duration (in months) = 10000 / 200 = 50
The duration of the loan is 50 months, however, the bank offers him a rate of 7.5%.
To calculate the total interest, we can use the formula:
Total Interest = Loan amount * Interest Rate * Duration (in months) / 12
The total interest is = 100007.5/10050/12 = 3750
So the Otis will have to pay an additional $3750 in interest over the course of the loan.
So, the total amount he will have to pay is 10000+3750 = 13750
And the time duration to pay this amount is 60 months ( 5 years)
Note: As per the information provided, the interest rate is not annual, it is monthly. So, it is not necessary to divide it by 12 in the interest formula. The equation should be Total Interest = Loan amount * Interest Rate * Duration (in months)

Russia 1996/4) In the Duma there are 1600 delegates, who have formed 16000 committees of 80 persons each. Prove that one can find two committees having at least four common members.
Answer:
Step-by-step explanation:
This problem can be solved using a technique called the Pigeonhole Principle. The Pigeonhole Principle states that if n+1 or more objects are placed into n pigeonholes, then at least one pigeonhole will contain two or more objects.
In this problem, we have 1600 delegates divided into 16000 committees of 80 persons each. We can think of each delegate as an object and each committee as a pigeonhole. Since 1600 delegates are placed into 16000 pigeonholes, we know that by the Pigeonhole Principle, at least one pigeonhole will contain two or more delegates.
In other words, there must be at least one committee that has at least two delegates in common with another committee. We can prove that there will be at least four common members by assuming the worse scenario where each committee is formed by different people, and noting that there are more delegates than the number of committees, so it's impossible that all committees have different members, and therefore there will be at least four common members.
Therefore, it is possible to find two committees having at least four common members.

What is equation?An equation is a mathematical formula that connects two assertions using the equal sign (=) to denote equivalence. In algebra, an equation is a mathematical statement that establishes the equivalence of two mathematical expressions. For instance, an equal sign separates the components 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula is used to explain the connection between two sentences on either side of a letter. Frequently, there is just one variable, which is also the symbol. for example, 2x - 4 = 2.
six whole pizzas, as well as = 5/8 of another pizza
another one = 1/8 of a whole pizza
Remain -by forming equation
let x = 5/8 of another pizza
and y = 1/8 of a whole pizza
remain = x+y = 5/8 + 1/8 = 6/8 3/4

the size of a television screen is given by the length of diagonal of the screen. What size is a tv screen the is 21.6 inches wide and 16.2 inches high
The size of a television screen that is 21.6 inches wide and 16.2 inches high is approximately 27 inches (measured diagonally).
What is the Pythagorean theorem?
It's a relation in Euclidean geometry among the three sides of a right triangle. In it, the square of the hypotenuse is equal to the sum of the squares of the other 2 sides.
The size of a television screen can be found by using the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.
In this case, the length of the diagonal of the screen is the hypotenuse, the width is 21.6 inches, and the height is 16.2 inches. We can use the theorem to find the length of the diagonal:
diagonal²= width² + height²
diagonal² = 21.6² + 16.2²
diagonal² = 467.76 + 262.44
diagonal² = 730.2
diagonal = √730.2
diagonal ≈ 27 inches
Hence, the size of a television screen that is 21.6 inches wide and 16.2 inches high is approximately 27 inches (measured diagonally).
