The subset of real numbers √3 belong to is irrational numbers
What is a subset ?
If all of the items in a set A are also in a set B, then the sets A and B are subsets of one another. To put it another way, the set A is contained within the set B. A and B stand for the subset connection.
When all the components of Set A are also present in Set B, Set A is said to be a subset of Set B. Alternatively said, Set B contains Set A. Example: If set A contains X and Y and set B contains X, Y, and Z, then set A is a subset of set B because set B also contains X and Y.
As √3 is irrational number

A −4
B −3
C −1
D 4
Answer:
None? Are you sure you copied the question right?
Step-by-step explanation:
x^2 - 3x - 4 = | x+3 | -2
Substitute
(-4)^2 - 3(-4) - 4 = | (-4)+3 | -2
16 + 12 -4 = 1-2
Not equal
(−3)^2 - 3(−3) - 4 = | (−3)+3 | -2
9+9-4 = -2
Not equal
(−1)^2 - 3(−1) - 4 = | (−1)+3 | -2
1 -3 -4 = 2-2
Not equal
4^2 - 3(4) - 4 = | 4+3 | -2

when $n$ is divided by $8$, the result is greater than $5$. what is the least possible integer value of $n$?
when N is divided by 8, the result is greater than 5 the least possible integer value of N is 48.
Zero, a positive natural number, or a negative integer with a minus sign are all examples of integers. The additive inverses of the positive numbers are the negative numbers. The boldface Z is frequently used in mathematics to denote the set of integers.
Positive integers: If a number is greater than zero, it is positive. Example: 1, 2, 3 . . .Negative integers: If a number is less than zero, it is negative. Example: -1, -2, -3 . . .Zero cannot be thought of as either a negative or a positive integer. It's an entire number.the least possible integer greater than 5 is 6,
and when 6 × 8 = 48 thus,

Answer: [tex]x\leq 0[/tex]
Step-by-step explanation:
The first thing we need to do is to make the argument or the number inside the square root equal or larger than zero:
-2x ≥ 0
x ≤ 0/-2
x ≤ 0
So the given expression only makes sense for x that is less than or equal to zero.

a. Is the relationship between time and distance an arithmetic sequence?
Explain.
b. The total distance a freely falling body covers in time, t, is given by the equation d(t)=1/2 gt2, where g is constant at 10 m/s². Show, in terms of n, the distance a falling body covers in t = n seconds of movement.
a. The given sequence is not an arithmetic sequence.
b. The distance a falling body covered in t = n seconds of movement is 5n²meters.
What is the distance?
Distance is a measurement of how far apart two things or points are, either numerically or occasionally qualitatively. The distance can refer to a physical length in physics or to an estimate based on other factors in common usage.
Here, we have
a. A sequence can be said arithmetic sequence if the difference between any two consecutive terms remains the same.
In this case, the difference between 20 and 5 is 15, and the difference between 45 and 20 is 25, this shows that the difference between two consecutive terms is not the same.
Hence, it can be said that the given sequence is not an arithmetic sequence.
b. To evaluate the distance covered by the body in “n” seconds, Substitute t=n in d(t) then d(n) will represent the distance covered by the body in “n” seconds
d(n)=1/2 g(n)²
d(n) = 1/2(10)(n)²
d(n) = 5n²meters
Hence, the distance a falling body covered in t = n seconds of movement is 5n²meters.

yard of fabric. The fabric costs $8 per yard.
You'll apply properties of multiplication in the following steps to find the total cost of the fabric.
1. Use multiplication to write an expression for the amount of fabric needed to make 13 pairs of wings. (2 points)
2. Multiply the amount of fabric by the price per yard to find an expression for the total cost.(2 points)
3. Use the associative and commutative properties to rearrange the terms in the expression to make it easier to calculate. Explain why the rearranged expression is easier to work with. (3 points)
4. Simplify your expression to find the total cost. Show your work. (3 points)
1) An expression for the amount of fabric needed to make 13 pairs of wings is; 3/4 * $8 = $6 each
2) An expression of the total cost is; 3/4 * $8 * 13 = $78
3) The way we will use associative and commutative properties is to start by treating 1 yard of fabric like the fraction 4/4.
4) Simplifying equals $78
How to solve algebra word problems?We are told that each pair of wings is made with 3/4 yard of fabric. Since the fabric costs $8 per yard. Thus;
1) 3/4 * $8 will give us the cost of the amount required for 3/4 yard of fabric. 3/4 * $8 = $6 each
2) Now, we are told that Mr. Townsend needs to make 13 pairs of butterfly wings and as such;
Amount needed to make 13 pairs is expressed as; 3/4 * $8 * 13 = $78
3) Treat 1 yard of fabric like the fraction 4/4.
Now, if this 1 fabric is equal to $8, then it means that 3/4 of the fabric will be $6. That is for one pair of butterfly wings, there's 13 of those so multiply $6 by 13.
This pattern is easier because we know how much 1 fabric costs, but we don't know what 3/4 of it does, so we treat 1 yard of fabric as the fraction 4/4.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.
The population has increased by 51.56% from last year to this year.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of population last year = 2,639,000,000
Number of population this year = 3,999,635,444
The best estimate of the total population of last year and this year.
= [ (3,999,635,444 - 2,639,000,000) / 2,639,000,000 ] x 100
