Step-by-step explanation:

You want the determinant of the coefficient matrix for the equations ...

The matrix of coefficients is formed by listing the coefficients of the equation variables on rows of the matrix, in the same order for each row.

Here it is:

  [tex]\left[\begin{array}{cc}3&4\\-2&3\end{array}\right][/tex]

The determinant of a 2×2 matrix is the difference between the product of terms on the down diagonal and that on the up diagonal.

  det = (3)(3) -(-2)(4) = 9 + 8 = 17

The determinant of the coefficient matrix is 17.

Many scientific and graphing calculators can find this for you. A spreadsheet can be useful for this purpose, too.

The determinant is only defined for a square matrix. For sizes larger than 2×2, the arithmetic is a little different.

Answer:

You can add 45 grams of water to 15 grams of sugar to make a 25% sugar solution.

Step-by-step explanation:

To make a 25% sugar solution, you need to add a certain amount of water to 15 grams of sugar. To determine this amount, you can use the following formula:

(desired concentration / 100) x total volume = amount of solute (in this case sugar)

We know that the desired concentration is 25%, and the amount of solute is 15 grams. To find the total volume, we can use the following formula:

amount of solute / desired concentration = total volume

15 grams / 0.25 = 60 grams

So the total volume of the solution is 60 grams, and the amount of water you need to add to make a 25% sugar solution using 15 grams of sugar is 45 grams.

You can add 45 grams of water to 15 grams of sugar to make a 25% sugar solution.

Another way to think of it is to add 3 times the amount of water as the amount of sugar, since 25% of 60g is 15g

What is the factor of the equation?

A factor in an expression is something that is multiplied by something else. It can be a number, variable, term or any other longer expression. For example, the factors of 2xy are 2, x and y.

We have,

(√x-1) - 5 = x - 8

To solve this equation, you can start by isolating the variable (x) on one side of the equation.

You can begin by adding 5 to both sides of the equation, which will give you (√x-1) = x-3.

Then, you can square both sides of the equation, which will give you x-1 = x^2-6x+9.

To solve for x, you can add 1 to both sides, which will give you x^2-6x+10=0.
You can then factor this equation to get (x-5)(x-2)=0.

Step-by-step explanation:

I think the actual equation you meant to write was 5x⁴ + 7x³ - 2x² - 3x + c.

You're going to equate the whole equation to 0 and replace x for -1( because x + 1 is a factor)

= 5(-1)⁴ + 7(-1)³ - 2(-1)² - 3(-1) + c = 0

= 5 - 7 - 2 + 3 + c = 0

= - 1 + c = 0

Therefore c = 1

It is neither row echelon form nor reduced row echelon form matrix

How do you know if a matrix is in echelon form or reduced echelon form matrix ?

A matrix is in reduced row-echelon form if it satisfies the following:

In each row, the left-most nonzero entry is 1 and the column that contains this 1 has all other entries equal to 0. ...

The leading 1 in the second row or beyond is to the right of the leading 1 in the row just above.

if you look at the two row echlon form you can see that it has leading entries(starting form left) that all one and there are no-zero elements above diagonal which can be any numbers (2,3,4, 6, x,y,x).

However reduced row echelon of has always leading elements 1 and are on diognal, this form is always like this therefore we can infer that reduced row echlon form is always uniqe as oppose to row echelon form.

The values of m and n are m = 123,000 and n = (123,000 - m1) / 2 + 1.

The given number is 123,000 which is the mth number in the nth row.

The rows contain two more numbers than the previous row.

Let us assume that the first row has m1 numbers.

Therefore, the second row has m1 + 2 numbers, the third row has m1 + 4 numbers, and so on.

We can represent the above information in a general formula as;

m1 + 2 (n - 1) = m

where m1 is the number of elements in the first row and n is the row number in which 123,000 is present.

By solving the above equation, we get

m1 = m - 2 (n - 1)

Now, we can calculate the value of n as;

n = (m - m1) / 2 + 1

Substituting the values of m and m1, we get

n = (123,000 - m1) / 2 + 1

Therefore, the values of m and n are m = 123,000 and n = (123,000 - m1) / 2 + 1.

[tex]y=\frac{3}{2}x-4[/tex]

Linear functions can be written in different forms such as standard and slope-intercept form.

Rewriting the Equation

To rewrite standard form (Ax + By = C) into slope-intercept, simply solve for y. To solve for y, we need to isolate it. We can do this using the properties of equality. Firstly, move x to the opposite side.

Subtract 3x from both sides.

Then, divide both sides by -2.

This is the slope-intercept form.

Interpreting the Values

Slope-intercept form is written as y = mx + b, m is the slope and b is the y-intercept. This means that the slope of the line we were given is 3/2. Additionally, the y-intercept is -4.

Answer:

y = 3/2 x - 4

Step-by-step explanation:

The given equation is:

Recall that the slope-intercept form is of the form:

Therefore the equation can be rewritten as follows:

Such a plot is evidence of a linear relationship between the explanatory and response variables, which is a condition for these inference procedure

These are the four presumptions: Relatively linear residuals Continuity of residuals The residuals are distributed normally. residual variance is same.

Linearity: We plot the residuals and y values in a scatter plot. Y values are shown on the horizontal x axis and standardized residuals, or ZRESID in SPSS, are derived from the vertical y axis. The linearity assumption is satisfied if the scatter plot displays a linear pattern (rather than a curved pattern).

We generally have two types of data: cross sectional and longitudinal. Cross -sectional datasets are those where we collect data on entities only once. For example we collect IQ and GPA information from the students at any one given time.

Independence is a concern when working with longitudinal datasets. With a longitudinal dataset, observations are gathered from the same subject across time. For example, in stock price information, we gather price information on the same stock, the subject, throughout time.

The two forms of data that we typically use are longitudinal and cross sectional. Datasets that are cross-sectional are those for which entities' information is only collected once. For instance, we constantly get IQ and GPA data from the kids.

We gather GPA data from the same student over time in a longitudinal data set.

We do not need to worry about the Independence assumption in cross-sectional datasets. It is "assumed" that it will be.

Normality: First, we create a histogram of the residuals, and then we check to see if they are normal. The assumption is met if the residuals do not exhibit skewness.

A scatterplot of the residuals vs the explanatory variable values shows a haphazard distribution of dots around the line.

Correct. This inference technique requires a linear relationship between the explanatory and response variables, which is demonstrated by a plot like this.

Answer:

[tex]f(a)=8a+5\\\\f(x+h)=8x+8h+5\\\\\frac{f(x+h)-f(x)}{h}=8[/tex]

Step-by-step explanation:

When we're asked to write what f(x+h) or f(a) is equal to, all we really have to do is substitution. The original function is provided as [tex]f(x)=8x+5[/tex], and all that "x" represents is input, now we can manipulate what that input is by simply substituting in new input. So if we want to write f(x+h), we substitute in "x+h" for "x".

For this problem, we just do what was stated about and replace all of the x's, with a's, meaning: [tex]8x+5\to 8a+5[/tex].

We essentially do the same thing here, although we will have to simplify more, but the first step is as follows: [tex]8x+5\to 8(x+h)+5[/tex], now from here we want to expand out the [tex]8(x+h)[/tex] by using the distributive property, so it becomes: [tex]8x+8h[/tex] and plugging this into our equation we get: [tex]8x+8h+5[/tex]

For this last question, I think it's also important to note that this is the formula to calculate the slope between point "x" and the point "h units away" or "x+h".

We already know what f(x+h) is and what f(x) is, so let's plug those into the equation:

[tex]\frac{(8x+8h+5)-(8x+5)}{h}[/tex]

Now let's distribute the negative sign to get:

[tex]\frac{8x+8h+5-8x-5}{h}[/tex]

Now let's group like terms:

[tex]\frac{(8x-8x)+(5-5)+8h}{h}[/tex]

Now let's simplify the grouped terms

[tex]\frac{8h}{h}[/tex]

Now let's divide by h to get:

How long is it?

well, our 4.05 half ends after the "2", so without a better calibration of the picture, hmmm 2.20 or thereabouts, let's make an assumption the "orange" section ends at 16, so that'd be 4.05 + (16 - 2) ≈ 18.05.

A regular singular point is a point at which the differential equation has a non-removable singularity. In order to identify a regular singular point, we must first identify the point at which the equation has a non-removable singularity. For problems 1-4, the point x=0 is a regular singular point. To find two solutions for x>0, we can solve the differential equation around x=0. First, we must identify the coefficients of the equation, which will allow us to determine the order of the equation. Once we have determined the order, we can use the properties of regular singular points to find two solutions for x>0. For example, the equation may be of the form y' + P(x)y = Q(x), where P(x) and Q(x) are functions of x. Using the properties of regular singular points, we can solve for two solutions of the form y = x^r*F(x), where F(x) is a function of x and r is the order of the equation.

2. Set h'(x) = 0 to find the critical points.

3. Since h'(x) < 0 for x < 0 and h'(x) > 0 for x > 0, h(x) is decreasing for x < 0 and increasing for x > 0.

4. Therefore, h(x) is increasing on the interval (0, ∞) and decreasing on the interval (-∞, 0).

The derivative of h(x) = 5 square root xe^-x is h'(x) = 5 (1/2 x^-1/2 e^-x - x^1/2 e^-x). Setting h'(x) = 0 gives the critical points of the function. Since h'(x) is negative for x < 0 and positive for x > 0, this tells us that the function is decreasing for x < 0 and increasing for x > 0. So, h(x) is increasing on the interval (0, ∞) and decreasing on the interval (-∞, 0). We can also conclude from the graph of the function that it is concave down for x < 0 and concave up for x > 0.
