Therefore, the distance between the two points is simply the difference in their x-coordinates, this makes sense since both points lie on the same horizontal line, and so the vertical distance between them is zero.
What is distance?Distance is a numerical measurement of how far apart two objects or points are from each other. It is a scalar quantity that is usually expressed in units of length, such as meters, kilometers, miles, or feet. Distance is often used in physics, mathematics, and engineering to describe the spatial separation between two objects or points. It is also used in everyday language to describe how far away something is, such as the distance between two cities or the distance from a person's house to their workplace.
By the question.
The distance between two points on a coordinate plane can be found using the distance formula:
distance =[tex]\sqrt{(x_{2}-x_{1})^{2}+ (y_{2}-x_{1}^{2} ) }[/tex]
In this case, the two points are (0, b) and (a, b). We can substitute these values into the distance formula:
distance = [tex]\sqrt{(a-0)^{2}+(b-b)^{2} }[/tex]
distance = [tex]\sqrt{a^{2}+0 }[/tex]

is it possible that all solutions of a homogeneous system of ten linear equations in twelve variables are multiples of one fixed nonzero solution? discuss.
Yes, it is possible for all solutions of a homogeneous system of ten linear equations in twelve variables to be multiples of one fixed nonzero solution.
This occurs when the rank of the matrix of coefficients of the system is less than the number of variables, in this case 12. In this case, the system has infinitely many solutions, all of which can be expressed as a multiple of one nonzero solution.
To illustrate this concept, consider the following system of two equations in three variables:
[tex]2x + y + 3z = 0[/tex]
[tex]3x + y + 2z = 0[/tex]
The matrix of coefficients for this system is:
[tex][[3, 1, 2][/tex]
[tex][2, 1, 3]][/tex]
The rank of this matrix is 2, which is less than the number of variables, 3. Therefore, this system has infinitely many solutions, all of which can be expressed as a multiple of the following nonzero solution:
[tex](x, y, z) = (2, -3, 1)[/tex]
In other words, any solution [tex](x, y, z)[/tex] of the system will be of the form [tex](2a, -3a, a)[/tex], where a is any real number. This concept can be generalized to systems of ten linear equations in twelve variables.
In conclusion, when the rank of the matrix of coefficients of a homogeneous system of linear equations is less than the number of variables, then all solutions of the system are multiples of one fixed nonzero solution.

During a catered lunch, an average of 4 cups of tea are poured per minute. The lunch will last 2 hours. How many gallons of tea should the caterer bring if there are 16 cups in one gallon? _____ gallons
Answer:30 gallons
Step-by-step explanation:
Answer:
30 gallons of tea
Step-by-step explanation:
Step 1:
First, before we do anything, let's convert 2 hours into minutes. There are 60 minutes in an hour, so we would multiply 60 and 2 to get 120 minutes.
Step 2:
Since we know that 4 cups of tea are poured every minute, we must multiply 4 by 120 because it is poured every 1 minute, and 4 × 120 = 480.
Step 3:
We also know that there are 16 cups of tea in one gallon, so we would divide 480 by 16 because we are trying to get how many gallons there are. 480 ÷ 16 = 30, so there are 30 gallons of tea poured in two hours.

50 Points!!! Are the Factor Theorem and Synthetic Division the same? If not, explain the difference.
Answer:
The Factor Theorem and Synthetic Division are not the same. The Factor Theorem states that if a polynomial f(x) has a root c, then x - c is a factor of f(x). Synthetic Division is a way of dividing a polynomial by a binomial.
Step-by-step explanation:
To use Synthetic Division, you first need to find the coefficients of the polynomial. Then, you set up the synthetic division table with the binomial on top and the coefficients of the polynomial on the bottom. Starting with the first coefficient, you multiply it by the first term of the binomial and write the product below the coefficient. Then, you add the two numbers below the product and write the sum below that. Continue until you reach the end of the binomial. The remainder at the bottom of the table is the remainder when f(x) is divided by x - c.
If the remainder is 0, then x - c is a factor of f(x).

What is the solution to this equation? 125^x-2= (1/25)^3x
The equation 125ˣ⁻² = (1/25)³ˣ when solved for x by the calculations below is 2/3
How to evaluate the equation for xWe can simplify both sides of the equation using the properties of exponents:
125ˣ⁻² = (1/25)³ˣ
Rewrite 125 as 5³ and 1/25 as 5⁻²
(5³)ˣ⁻² = (5⁻²)³ˣ
Simplify the exponents by multiplying:
5³ˣ ⁻ ⁶ = 5⁻⁶ˣ
Now we can see that the equation involves powers of the same base (5).
Therefore, we can solve for x by equating the exponents:
3x - 6 = -6x
Add 6x to both sides:
9x - 6 = 0
Add 6 to both sides:
9x = 6
Divide both sides by 9:
x = 2/3

how many ways are there to put 23 identical objects into 7 distinct containers so that no container is empty?
This problem is a classic example of applying the stars and bars combinatorial method.
To solve this problem, we need to distribute 23 identical objects into 7 distinct containers so that none of the containers is empty. Let's start by assuming that each container has at least one object. This means we have distributed 7 objects, leaving 16 objects to be distributed.
We can now use the stars and bars method to distribute these 16 objects. Imagine placing all 16 objects in a line, and placing 6 dividers between them to separate them into 7 groups (one for each container). Each group will then receive the objects that are to the left of the divider.
For example, if we have the sequence OO|OOO|O|OOO|OO|OO|O, this corresponds to 2 objects in the first container, 3 objects in the second container, 1 object in the third container, and so on.
The number of ways to place the 6 dividers in the sequence of 16 objects is the same as the number of ways to choose 6 positions out of 16 to place the dividers. This can be computed using the formula for combinations:
$${16 \choose 6} = \frac{16!}{6!(16-6)!} = 8008$$
Therefore, there are 8008 ways to distribute 23 identical objects into 7 distinct containers so that no container is empty.

Use fractions strips to help find the difference. Answer your answer in simplest form three and five 1 and two
To find the difference between 3/5 and 1/2 using fraction strips, we can use strips that are divided into fifths and halves, respectively.the difference between 3/5 and 1/2 is 2/10 or 1/5, , the answer in the simplest form is 1/5.
What is the use of fractions strips?First, we'll need to represent each fraction using the fraction strips.
For 3/5, we can use three fifths strips to represent the numerator and put them together to form a whole.
For 1/2, we can use one half strip and cut it into two equal parts to represent the numerator.
Next, we'll need to compare the two fractions by placing them side by side.
We can see that the two fractions do not have the same denominator, so we need to find a common denominator to make the comparison easier.
The smallest common multiple of 5 and 2 is 10, so we can represent 3/5 using six tenths strips, and 1/2 using five tenths strips.
We can see that there are two tenths strips that are not shared between the two fractions.
Therefore, the difference between 3/5 and 1/2 is 2/10 or 1/5, , the answer in the simplest form is 1/5.

The central limit theorem (CLT) of probability theory states that, under the assumption that all samples are of equal size and regardless of the population's actual distribution shape, the distribution of a sample variable approaches a normal distribution (i.e., a "bell curve") as the sample size increases.
In other words, the central limit theorem (CLT) is a statistical assumption that, given a sufficiently enough sample size from a population with a limited degree of variance, the mean of all sampled variables from the same population will be roughly equal to the mean of the entire population.

The ratio of boys to total kids can be expressed in three different ways fraction, decimal, and percent which are 27:59, 0.4576 and 45.76% respectively.
First, let's find the total number of kids in the program. The total number of kids in the program is the sum of boys and girls. Total kids = boys + girls = 27 + 32 = 59. Now that we have the total number of kids, we can find the ratio of boys to total kids in three different ways. 1. Fraction: The ratio of boys to total kids can be expressed as a fraction, where the numerator is the number of boys and the denominator is the total number of kids. Boys: Total kids = 27:59 This fraction cannot be simplified.
2. Decimal: The ratio of boys to total kids can also be expressed as a decimal. To find the decimal, divide the number of boys by the total number of kids. Boys/Total kids = 27/59 = 0.4576 (rounded to four decimal places). 3. Percent: The ratio of boys to total kids can also be expressed as a percentage. To find the percentage, multiply the decimal by 100. Boys/Total kids × 100 = 0.4576 × 100 = 45.76%. Therefore, the ratio of boys to total kids can be expressed as a fraction, decimal, and percent as shown above.
