Now that we know the value of x, we can find the values of DP, PH, and HD:

DP = 17x = 17(0.295) = 5.015

PH = 6x + 5 = 6(0.295) + 5 = 6.77

HD = 20x - 3 = 20(0.295) - 3 = 2.9

Therefore, DP ≈ 5.015, PH ≈ 6.77, and HD ≈ 2.9.

The perimeter of a form is its edge's radius. Learn how to multiply the lengths of a shape's sides to determine its perimeter.

To solve this problem, we need to use the fact that the perimeter of ADPH is 23.5. We know that AD = DP + HD, and we also know the values of DP, PH, and HD in terms of x. So, we can set up an equation using these values and solve for x.

AD = DP + HD

AD = 17x + (20x - 3)

AD = 37x - 3

Perimeter of ADPH = AD + DP + PH + HD

23.5 = (37x - 3) + 17x + (6x + 5) + (20x - 3)

Simplifying the above equation, we get:

23.5 = 80x - 1

Solving for x, we get:

x = 0.295

Now that we know the value of x, we can find the values of DP, PH, and HD:

DP = 17x = 17(0.295) = 5.015

PH = 6x + 5 = 6(0.295) + 5 = 6.77

HD = 20x - 3 = 20(0.295) - 3 = 2.9

The reminder of F(x)  when it is  divided by x-3 by using the factorizing method is equal to 8.

The Remainder Theorem is a method to Euclidean polynomial division. According to this theorem, dividing a polynomial P(x) by a factor (x - a), which is not an element of the polynomial, yields a smaller polynomial and a remainder.

"f(x) is divided by (x - 3)" is the mathematical expression for the statement.

Further simplify the above expression.

[tex](x^3+3x^2+4x+6) + \frac{8}{x-3}[/tex]

Thus, when f(x) is divided by (x - 3), the remaining is 8.

The Remainder Theorem starts with a polynomial, say p(x), where "p(x)" is a polynomial p with x as a variable. Then, according to the theorem, divide that polynomial p(x) by some linear factor x - a, where an is just some number. A lengthy polynomial division is performed here, yielding some polynomial q(x) (the variable "q" stands for "the quotient polynomial") and a polynomial remainder is r. (x).

Answer:

the coordinates of the point that partitions the directed line segment from (-6,-2) to (9,-7) into a ratio of 3 to 2 are (0, -4).

Step-by-step explanation:

To find the coordinates of the point that partitions the directed line segment from (-6,-2) to (9,-7) into a ratio of 3 to 2, we can use the following formula:

P = ( (2bx + 3ax)/(2+3) , (2by + 3ay)/(2+3) )

where P is the point we are looking for, (ax, ay) and (bx, by) are the coordinates of the two endpoints of the line segment, and the numbers 2 and 3 represent the ratio in which the line segment is to be divided.

Substituting the given values, we get:

P = ( (29 + 3(-6))/(2+3) , (2*(-7) + 3*(-2))/(2+3) )

= ( (18 - 18)/5 , (-14 - 6)/5 )

= ( 0, -4 )

Therefore, the coordinates of the point that partitions the directed line segment from (-6,-2) to (9,-7) into a ratio of 3 to 2 are (0, -4).

Option C. 1 13/18

Step-by-step explanation:

8/9 + 2/3 + 1/6

Taking LCM as 18

8/9 × 2/2 + 2/3 × 6/6 + 1/6 × 3/3

16/18 + 12/18 + 3/18 = 31/18 = 1 13/18

y = 3x - 4 is the equation of the line in slope intercept form. Option C is correct

The formula for calculating the equation of a line in point slope form is expressed as:

y - y0 = m(x - x0)

where:

m is the slope

(x0, y0) is the point on the line

Using the coordinate points (2, 2) and (0, -4). The slope is calculated as:

Slope = -4-2/0-(2)
Slope = -6/-2
Slope = 3

The required equation will therefore be expressed as:

y + 4 = 3(x - 0)

y + 4 = 3x

y = 3x - 4

The diamond problem solver is a graphical tool used to solve problems involving the addition and multiplication arithmetic operations.

It is frequently used in elementary mathematics to assist students in comprehending the relationship between these operations and their inverse operations of subtraction and division.

The diamond problem solver gets its name from the fact that it is drawn in the shape of a diamond with four sections. The sum or product is represented by the top section, the addends or factors are represented by the two side sections, and the missing value is represented by the bottom section.

We use the diamond problem solver by writing the known values in the diamond's two side sections and filling in the missing value in the bottom section. Then we add or multiply the known values to find the value in the diamond's top section.

For example, to solve the problem:

7 + ___ = 12

We would write 7 in the left section of the diamond and 12 in the top section, leaving the right section blank. We then fill in the bottom section with the missing value by subtracting 7 from 12:

12 - 7 = 5

So, the value in the bottom section of the diamond is 5, and the completed diamond would look like this:

  [tex]07\\+ ?\\-\\ 12[/tex]

[tex]07\\+ 5\\--\\ 12[/tex]

As a result, the problem's missing value is 5. The diamond problem solver can also be used to solve multiplication problems by placing the known values in the side sections and the product in the top section.

Explanation:

You want synthetic division explained for division of (2x^4 -3x^3 -5x^2 +3x +8) by (x-2).

In general, synthetic division is long division without writing the variables. It takes advantage of the fact that subtracting the product of the quotient term and the divisor makes the leading term go to zero at each step. This makes it possible to write the entire division on one line, instead of several. (The long division of these polynomials is shown in the second attachment.)

Synthetic division is most easily accomplished as division of a polynomial by a monic binomial—a binomial of the form x -a. Both dividend and divisor can be divided by the leading coefficient of the divisor if it is not 1.

The first attachment shows the tableau that is used during the synthetic division process. At top left is the opposite of the divisor constant. (This is the value that makes the divisor zero.) By using the opposite of the constant, later steps can involve addition, rather than subtraction, which simplifies the process and reduces errors.

To the right of the divisor zero, the coefficients of the polynomial are listed in decreasing order of degree. If a polynomial term is missing, then a 0 is used for its coefficient. Typically, the tableau is drawn with a vertical line between the divisor zero and the polynomial coefficients.

A horizontal line is drawn below the coefficients, with enough space to allow for partial products to be written between the coefficients and the horizontal line. The first (left-most) dividend polynomial coefficient is copied below the line.

From here, steps for succeeding columns of the tableau are the same. Working left-to-right, the value just written below the line is multiplied by the divisor zero, and that product is written above the line in the next column to the right. The coefficient is added to that, and the sum is written below the line.

The sum in the final (rightmost) column is the remainder from the division. The quotient from the division has the set of coefficients that are the numbers below the line to the left of the remainder.

As shown in the attachment, the result of using synthetic division for the given polynomials is ...

  2 1 -3 -3 2

This means the quotient is 2x³ +x² -3x -3 and the remainder is 2. That is, ...

  (2x⁴-3x³-5x²+3x+8) ÷ (x-2) = 2x³ +x² -3x -3 + 2/(x-2)

__

Additional comment

Synthetic division is really designed for division by monic binomials. It can be extended (with extreme care) to division by monic polynomials of higher degree than 1. What makes it work is the fact that the leading dividend term disappears at each step, so no accounting for the coefficients of the leading terms is required.

The same trick of using sums instead of differences could be applied to long division—again, with extreme care.

On the other hand, ordinal variables can have two or more categories, but they can be ordered or ordered. In addition to categorical variables, other types of variables are used, such as interval and ratio variables. An example of a dummy variable is hair color. Indeed, the hair can be of different colors like blond, black, brown, red, etc. These categories cannot be sorted and no operations can be performed.

Real Variable:

A real variable is one that does not take into account the effects of price and/or inflation. Conversely, nominal variables are variables that do not take into account the effect of inflation.
