Answer:

[tex]27)x {}^{3} + 3x {}^{2} - 10x - 24 \\ 28)x {}^{3} - 9 {}^{2} + 8x + 60[/tex]

Step-by-step explanation:

Greetings!!

[tex]27)(x - 3)(x + 2)(x + 4)[/tex]

Expand; (x-3)(x+2): x^2-x-6

Apply FOIL method: (a+b) (c+d) = ac+ad+bc+bd

[tex](x - 3)(x + 2) = x.x + x.2 - 3.x - 3.2[/tex]

simplify

[tex]x {}^{2} - x - 6[/tex]

[tex]x {}^{2} - x - 6.(x + 4)[/tex]

distribute parentheses

[tex] = x {}^{2} .x + x {}^{2} .4 - x.x - x.4 - 6.x - 6.4 \\ = x {}^{3} + 4x {}^{2} - x {}^{2} - 6x - 24[/tex]

simplify/ Add similar elements

[tex]x {}^{3} + 3x {}^{2} - 10x - 24[/tex]

Thus, use the same format for question number 28 and you will get the value

[tex]x {}^{3} - 9x {}^{2} + 8x + 60[/tex]

So, on solving the provided question, we can say that coefficient of the variable in the expression 2 − 5x − 4 8 is 5

A coefficient in mathematics is a polynomial, a series, or the multiplicative coefficient of a particular term in an expression. Typically numeric, however any expression is permitted. The term "parameter" can also refer to the coefficients themselves if they are variables. A number times a variable equals a coefficient. Coefficient examples include:  The coefficient is 14 in phrase 14c 14c 14c. The coefficient is 1 for word g. multiplies the variable by this amount. example  Given that "z" is a variable and that 6z is the definition of the term, the coefficient is 6. One is the coefficient of the square of x.

b) The total payment to be made is $41,989.80.

c) The finance charge is $3,989.80.

The finance charge is the difference between the sum of the monthly payments and the loan amount.

The monthly payments, total payment, and finance charge can be computed using an online finance calculator as follows:

N (# of periods) = 60 months (5 years x 12)

I/Y (Interest per year) = 4%

PV (Present Value) = $38,000

FV (Future Value) = $0

Results:

PMT (Monthly Payments) = $699.83

By replacing the values of the point in the quadratic equation, we can see that it is not a solution.

Here we have the quadratic equation:

The parent function of the quadratic family is f(x) = x2. A transformation of the graph of the parent function is represented by the function g(x) = a(x − h)2 + k, where a ≠ 0.

A quadratic function is one of the form f(x) = ax2 + bx + c, where a, b, and c are numbers with a not equal to zero.

A parabola is the shape of a quadratic function's graph. Although the "width" or "steepness" of a parabola can vary as well as its direction of opening, they all share the same fundamental "U" form. The three graphs in the image below are all parabolas.

A quadratic function's graph takes the form of a parabola. The parabola will open upward if the value of the "a" term is positive, and downward if the value is negative

A function can be raised by adding outside of it: f (x) + b raises f (x) by b units. The same principles apply for moving a function down, except instead of subtracting a positive integer, f (x) b represents f (x) moved down b units.

You can represent a vertical (up, down) shift of the graph of f(x)=x2 by adding or subtracting a constant, k.

f(x)=x2+k

By increasing or decreasing the output or the input, you can change the direction of the function's graph to the right, left, up, or down. A function's output can be increased to move the graph up. The graph is shifted downward when a function's output is subtracted from.

The output has a constant added to it, which causes the vertical shift. For a positive constant, move the graph upward; for a negative constant, move it below. A constant supplied to the input causes a horizontal shift. For a positive constant, move the graph to the left; for a negative one, move it to the right.

You can represent a horizontal (left, right) shift of the graph of f(x)=x2  by adding or subtracting a constant, h, to the variable x, before squaring.

f(x)=(x−h)2

If h>0, the graph shifts toward the right and if  h<0 , the graph shifts to the left.

The fundamental theorem of algebra states that for any non-constant polynomial equation with real or complex coefficients, there is at least one complex root (or solution).

In the case of the equation 2x^2+8x+14=0, the theorem guarantees that this equation has at least one complex root, which means that there are numbers that can be plugged into x that will make the equation equal to zero.

So, the fundamental theorem of algebra guarantees that for the equation 2x^2+8x+14=0, there exists at least one complex solution that makes the equation true. In this case, the solutions are x = -1+i and x = -1-i ✅

Yes, (3, 2) is an ordered pair.

The combination of the x coordinate (abscissa) and the y coordinate (ordinate) is called an ordered pair, which has two values written in a fixed order within parentheses.

It can help us to locate a point on the cartesian plane for better visual understanding. The numerical values in an ordered pair can be both integers or fractions. 

In the Cartesian plane, we can define a two-dimensional space with two perpendicular reference lines, the x-axis and the y-axis. The point where the two lines meet is the origin (O).

For example plot the point Q with the coordinates (3, 2)

According to the definition of ordered pair, the point Q will be written as:

Q = (3, 2)

The numeric value for the logarithmic expressions is given as follows:

2. [tex]\log_6{40} = 2.059[/tex]

3. [tex]\log_6{64} = 2[/tex]

4. [tex]\log_6{125} = 2.694[/tex]

b. [tex]\log_5{330} = 3.603[/tex]

c. [tex]\log_5{121} = 2.98[/tex]

For the first expression, we have that the logarithm of the quotient is the subtraction of the logarithms, hence:

[tex]\log_{6}{\left(\frac{5}{8}\right)} = \log_6{5} - \log_6{8} = 0.898 - 1.161 = -0.263[/tex]

The same rule is applied for item a, hence:

[tex]\log_{5}{\left(\frac{11}{30}\right)} = \log_5{11} - \log_5{30} = 1.49 - 2.113 = -0.623[/tex]

For the second expression, we apply the logarithm of the product, which is the sum of the logarithms, hence:

[tex]\log_6{40} = \log_6{5 \times 8} = \log_6{5} + \log_6{8} = 0.898 + 1.161 = 2.059[/tex]

For item b, we have that:

[tex]\log_5{330} = \log_5{11 \times 30} = \log_5{11} + \log_5{30} = 1.49 + 2.113 = 3.603[/tex]

For the third expression, we have that the exponent is equals to the base, hence we just take the lower term, as follows:

[tex]\log_6{64} = \log_6{2^6} = 2[/tex]

For the fourth term, we have the rule for the logarithm of an exponent, hence:

[tex]\log_6{125} = \log_6{5^3} = 3\log_6{5} = 3 \times 0.898 = 2.694[/tex]

The same rule is applied for item c, as follows:
