Find the product:
[2 1 0] x [1 -1 2] = [a b c]
[-1 -2 1]
[0 1 1]

Answer:

d = 18

Step-by-step explanation:

d = square root (x2 -  x1)^2 + (y2 - y1)^2

Point A ( -1,2) Point B (1,-2)

Now let's put the number in

d = square root ( 1 -(-1)^2 + (-2 - 2)^2

Now let's get rid of the square root, and we have

(1-(-1) + (-2 -2)^2

2 + (-4)^2

2 + 16

18

So, the distance AB = 18

Answer:

[tex]AB = 4.5[/tex]

Step-by-step explanation:

⭐To find the distance between two points, you can use the distance formula: [tex]d = \sqrt{(x_2-x_1)^2 +(y_2 - y_1)^2}[/tex], where:

First, identify the coordinates you need to find the distance between, and label one coordinate as [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex].

Next, substitute [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] into the distance formula.

[tex]d = \sqrt{(1-(-1))^2+(-2-2)^2}[/tex]

[tex]d = \sqrt{(1+1)^2+(-4)^2}[/tex]

[tex]d = \sqrt{2^2+(-4)^2}[/tex]

[tex]d = \sqrt{4+16}[/tex]

[tex]d = \sqrt{20}[/tex]

∴ d ≈ 4.5

In Euclidean geometry, parallel lines (lines that never intersect) are equidistant in the sense that the distance of any point on one line from the nearest point on the other line is the same for all points.

In geometry, parallel lines can be defined as two lines in the same plane that are at equal distance from each other and never meet. They can be both horizontal and vertical. We can see parallel lines examples in our daily life like a zebra crossing, the lines of notebooks, and on railway tracks around us.

There are 3 main rules:

Corresponding angles are equal. A line cutting across two parallel lines creates four pairs of equal corresponding angles, as in the diagram below.

Total 1,512,000 "words" can be formed by rearranging INQUISITIVE so that U does not immediately follow Q.

In the given question, we have to find how many "words" can be formed by rearranging INQUISITIVE so that U does not immediately follow Q.

The given word is INQUISITIVE.

The total alphabets in the word INQUISITIVE is 11.

Let us first count the words without U and then insert U wherever applicable.

Now without U we have total 10 alphabets and the alphabet I is repeated by 4 times.

So permutations is 10!/4! = 151,200

Now we need to put U, we can see its 11 alphabets but U should not follow Q so it becomes 10 alphabets.

Hence, Total number of words = 151,200*10

Total number of words = 1,512,000

Hence, 1,512,000 "words" can be formed by rearranging INQUISITIVE so that U does not immediately follow Q.

Discontinuous variation refers to characteristics that have only a limited range of values within a population. Eye color is one example of discontinuous variation, as the range of colors is limited and individuals can only have one of these colors. Similarly, blood type is another example of discontinuous variation, as it is determined by the presence or absence of certain antigens in the blood and individuals can only have one of the four blood types. Discontinuous variation is often inherited, determined by the presence or absence of certain genes or alleles. These variations are usually determined by a single gene with two alleles, one of which may be dominant and one of which may be recessive, leading to the limited range of values. Discontinuous variation, then, is an important part of the human population and helps to create the variety and diversity that exists within it.

The polynomial p(x) must have at least two zeros.

A polynomial p(x) can have a maximum, minimum, or neither at any given point. The number of zeros of p(x) is equal to the number of positive and negative changes in the sign of the coefficients of the polynomial.

Since p(1) has a relative maximum at (-20), a relative minimum at (13) and a relative maximum at (57), there must be at least two changes in the sign of the coefficients. Therefore, the polynomial p(x) must have at least two zeros.

To determine how many zeros the polynomial has, we will need to calculate the sign of the coefficients at each point. For example, if the coefficient of x2 is positive at x = -20, but negative at x = 13, then we know that the polynomial has one zero between -20 and 13. We can use this method to determine the number of zeros of p(x).

it is always important to carefully evaluate the assumptions of the model and confirm that it is an appropriate fit for the data.

What is Explanatory Variables?

A researcher-manipulated variable is an explanatory variable when it comes to an experiment. It serves as a measurement of the change brought about in the response variable. A predictor variable or an independent variable are terms that are frequently used to describe an explanatory variable.

It is not possible to determine whether a Poisson regression model would be a good choice for any of the explanatory variables without further information.

To determine whether a Poisson regression model is a good fit for the data, you will need to consider the following:

The relationship between the response variable (i.e., the observed species counts) and the explanatory variables should be modeled using a linear relationship. This can be visually assessed by creating scatterplots of the logged response variable against each of the explanatory variables and examining the pattern of the points. If the points form a roughly linear pattern, then a Poisson regression model may be appropriate.

The response variable should follow a Poisson distribution. This can be assessed by examining the distribution of the logged response variable using a histogram or a Q-Q plot. If the distribution is approximately symmetrical and has a single peak, then a Poisson regression model may be appropriate.

The residuals (i.e., the difference between the observed and predicted values) of the model should be approximately normally distributed with a mean of zero. This can be assessed by creating a plot of the residuals against the fitted values and examining the pattern of the points. If the points form a roughly random pattern centered around zero, then the model is likely to be a good fit.

If all of these conditions are met, then a Poisson regression model may be a good choice for modeling the relationship between the response variable and the explanatory variables.

However, it is always important to carefully evaluate the assumptions of the model and confirm that it is an appropriate fit for the data.

The rule to identify the number of solutions to the system of equation is written as,

In the given equation (a1/a2) ≠ (b1/b2), then there will be a unique solution.

Where as If (a1/a2) = (b1/b2) = (c1/c2), then there will be infinitely many solutions.

Finally If (a1/a2) = (b1/b2) ≠ (c1/c2), then there will be no solution.

Here we have given that pair of equations to show if the system has no solution, one solution, or infinitely many solutions.

Here we have to take the first equation

a. 3y = -12x + 6 l y= -4x+ 2

Now, we have to write it in the standard form, then we get,

The next two odd consecutive integers are (2n + 3) and (2n + 5) if 2n + 1 is an odd number. For illustration, assume that 2n + 1 is the odd number 7. Its successive numbers are identified as (7 + 2) and (7 + 4), or 9 and 11. Consecutive odd numbers are odd integers that are separated by 2 and come after one another. If the number x is odd, then the numbers x + 2, x + 4, and x + 6 are also odd.

Any collection of consecutive odd numbers starting with 1 has a sum that is always equal to the square of the total number of digits. If the numbers 1, 3, 5, 7, 9, 11,..., and (2n-1) are odd, then the sum of the first odd number is 1. First two odd numbers added together equal 1 + 3 = 4 (4 = 2 x 2).

x = 3

plug in 3 for x in JN's equation

JN = 15 - 2(3)

Step-by-step explanation:

To find this algebraic phrase, we need to use the rules of algebra to express the given statement in mathematical notation. The given statement says that the sum of three times the opposite of a number and -7 is some unknown value.

We can start by expressing the opposite of a number in mathematical notation. The opposite of a number is equal to the number multiplied by -1. So, we can write the opposite of a number as -x.

Next, we can express the fact that the opposite of a number is being multiplied by 3. To do this, we can simply write 3(-x) to represent three times the opposite of a number.

Finally, we can express the fact that -7 is being added to the result. To do this, we can simply write 3(-x) - 7 to represent the sum of three times the opposite of a number and -7.

Therefore, the algebraic phrase for the sum of three times the opposite of a number and -7 is 3(-x) - 7.

The Median of 10 and 24 is 17.
