2/ ( 1 + x) ( 1 - x) is express  into partial fractions.

With an example, what is a partial fraction?

The division of an algebraic fraction into smaller, "partial fractions," components is possible. Think about the algebraic fraction (3x+5) (2x2-5x-3). This formula can be broken down into its simplest form, [2/(x - 3)] - [1/(2x + 1)]. Partial fractions are the more straightforward pieces [2/(x - 3)] and [1/(2x + 1)].

                        The four categories of partial fractions are linear factors, degree 2 irreducible factors, repeated linear factors, and repeated irreducible degree 2 factors.

Step-by-step explanation:

Although the answer is correct, the Step 3 is not correct.

It will take Omari 7 months to pay off the computer.

What is a percentage?

Percentages are essentially fractions where the denominator is 100. To show that a number is a percent, we use the percent symbol (%) besides the number. For example, if you got 75 questions right out of 100 on a test (75/100), you would have scored 75%.

To find the amount of the down payment, multiply the price of the computer by the down payment percentage:

down payment = $1,099 * 20% = $219.80

The remaining balance on the computer after the down payment is:

remaining balance = $1,099 - $219.80 = $879.20

To find the total number of months it will take Omari to pay off the computer, divide the remaining balance by the monthly payment:

total months = $879.20 / $144/month = 6.1 months

Since it is not possible to have a fraction of a month.

Hence, it will take Omari 7 months to pay off the computer.

The value of (5x2−14x+24)÷(x−4)  is 5x + 6

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement.

Given ,

5x2 - 14x - 24

         x - 4    

  5x2 multiplied by 14x, then 24.

The first term is 5x2, and 5 is its coefficient.

The coefficient of the middle term, which is -14x, is -14.

"The constant," the final term, is -24.

Step 1: Multiply the first term's coefficient by the constant 5 • -24 to get a result of -120.

Find two factors of -120 whose combined value is equivalent to the middle term's coefficient, which is -14, in step two.

    -120    +    1    =   -119  

    -60    +    2    =    -58  

    -40    +    3    =    -37  

    -30    +    4    =    -26  

    -24    +    5    =    -19  

    -20    +    6    =    -14    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -20  and  6  

                   5x2 - 20x + 6x - 24

Step-4 : Add up the first 2 terms, pulling out like factors :

                  5x • (x-4)

            Add up the last 2 terms, pulling out common factors :

                  6 • (x-4)

Step-5 : Add up the four terms of step 4 :

                 (5x+6)  •  (x-4)

Simplified term is 5x + 6. Simplification is the process of reducing an expression/fraction/problem to a simpler form.

A mathematical expression is simplified when it is replaced with a simpler, typically shorter, equivalent statement.

Mathematical expressions are made up of different numbers and operations. To simplify them, we must first understand the rule known as the order of operations. It specifies the order in which operations must be performed when simplifying a mathematical expression.

Time taken by the bicyclist is 8 hours.

Slope is calculated mathematically as "rise over run" (change in y divided by change in x).

Given slope = 35 / 2 = 17.5

Distance = 140 miles.

then time is calculated by 140 /17.5

 = 8 hours

The slope expresses how quickly the dependent variable changes when the independent variable changes. The Greek capital letter D or D is frequently used by mathematicians and economics to represent change. Slope contrasts the change in the vertical axis, y, with the change in the horizontal axis, x.

As x grows, there are 4 different sorts of slopes: negative, positive, zero, and undefined. The "average rate of change" can also be thought of as the slope of a line.

Answer:

C(-6, -3)

Step-by-step explanation:

In a square, all four sides have the same length and all four angles have the same measure (90 degrees). Therefore, the line segments connecting the vertices of a square are all perpendicular to each other and all have the same length.

Since the line segment AB has a length of 8 (the difference in the y-coordinates is 8) and a horizontal component (the difference in the x-coordinates is 0), the line segment CD must also have a length of 8 and a horizontal component of 0. This means that the x-coordinate of point C is the same as the x-coordinate of point A, which is 2.

The line segment CD also has a vertical component equal to the difference in the y-coordinates of points D and A, which is 5 - (-3) = 8. Therefore, the y-coordinate of point C is the same as the y-coordinate of point D minus 8, or -3.

Therefore, the coordinates of point C are (-6, -3).

The coordinates of the intersection with the x-axis are

(8,0), and the coordinates of the point where x = -3, (-3 0).

What are the coordinates of the axis?

A Cartesian coordinate system in a plane is a system of coordinates that uniquely identifies each point by a pair of numerical coordinates. These numerical coordinates are the signed distances from two fixed perpendicular oriented lines to the point, measured in the same unit of length.

We have,

The graph shows the sketch of y = f(x).

The graph crosses the y-axis at the point (0,-2), and the x-axis at the point (8,0).

The coordinates of the intersection with the x-axis are:

y = 0

If two numbers can be placed exactly over one another, they are said to be "congruent." When placed one on top of the other, the two bread slices are the same size and form. Things that are precisely the same size and shape are said to be congruent.

What are the five different types of congruence?
Two triangles are congruent if they satisfy all five conditions for congruence. Right angle-hypotenuse-side (RAHS), angle-side-angle (ASA), angle-angle-side (AAS), side-side-side (SSS), and side-angle-side (SSS) are the four terms (RHS).

This can be solve by congruence

these two triangle can be congruent by AAS

The minimum number of dogs that have a mass of more than 24kg is 6 and the maximum number of dogs that could have a mass of more than 24kg is 18  

Using fundamental algebraic principles, rearrange the function to get the value of x at the derivative value of 0. The maximum or minimum will be at the vertex of the function, which is indicated by the response's x-coordinate. Rewrite the answer into the original function to determine the minimum or maximum.    

Here we have

The given shows the masses of various dogs  

Mass (x) kg          frequency  

0 ≤ x < 10                    2

10 ≤ x < 20                  7

20 ≤ x < 30                12

30 ≤ x < 40                 6      

a) The minimum number of dogs that have a mass of more than 24kg.

If we observe the given table the mass of 24 kg will lie in class intervals 20 ≤ x < 30, 30 ≤ x < 40                      

In class interval 20 ≤ x < 30, mass ranges from 20 kg to 30 kg there is a possibility that the mass of dag will be less than 24 since it started from 20 kg,  

In class interval 30 ≤ x < 40, mass ranges from 30 kg to 40 here there is no possibility that the mass will be less than 24 kg.

So here we can take the frequency of class interval 30 ≤ x < 40 as the Minimum value or number of dogs that could have a mass of more than 24 kg

Therefore,

The minimum number of dogs that have a mass of more than 24kg is 6

b) The maximum number of dogs that have a mass of more than 24kg.

In the above case since we are calculating minimum value, we didn't consider class interval 20 ≤ x < 30.

In this case, to get the maximum value or a maximum number of dogs we will consider class interval 20 ≤ x < 30 as there is a possibility that the mass could be more than 24 kg

In class interval 30 ≤ x < 40 the mass will always be more than 24 kg.

Thus, the Maximum number of dogs with more than 24 kg = 12 + 6 = 18

Therefore,

The maximum number of dogs that could have a mass of more than 24kg is 18

The pressure of 28 inches of mercury occurs at 6.03 miles from the eyes of the hurricane

From the question, we have the following pressure function that can be used in our computation:

f(x) = 0.48 ln(x + 2) + 27

Also from the question, we have

Pressure = 28 inches

This means that

f(x) = 28

So, we have the following equation

0.48 ln(x + 2) + 27 = 28

Subtract 27 from both sides

0.48 ln(x + 2) = 1

Divide 0.48 from both sides

ln(x + 2) = 2.083

x + 2 = 8.03

So, we have
