To calculate marginal utility, you need to determine the additional utility that a consumer derives from consuming an additional unit of a good or service. This involves finding the difference in total utility before and after consuming the additional unit.

Marginal utility is the additional utility (or satisfaction) that a consumer derives from consuming an additional unit of a good or service. To calculate marginal utility, you can follow these steps:

1. Determine the total utility that a consumer derives from consuming a certain amount of a good or service.

2. Increase the amount consumed by one unit.

3. Determine the new total utility that the consumer derives from consuming the additional unit.

4. Subtract the initial total utility from the new total utility to obtain the marginal utility of the additional unit.

The slope is 1/19.5 and it is positive slope.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The formula to find the slope of a line is slope = (y₂-y₁)/(x₂-x₁).

Given that, the cost of tickets to the amusement park is $19.50 for 1 ticket and $78 for 4 tickets.

Here, the coordinates are (19.50, 1) and (78, 4)

Now, the slope = (4-1)/(78-19.50)

= 3/58.5

= 1/19.5

Therefore, the slope is 1/19.5 and it is positive slope.

Answer:

The value of [tex]x[/tex] is [tex]55\textdegree[/tex].

Step-by-step explanation:

A straight line is equal to 180 degrees.

So any angles that forms on the same side of a straight line always add to 180 degrees.

We are given an angle of [tex]130\textdegree[/tex] on the exterior of the triangle.

Lets call the angle next to that [tex]\angle B[/tex].

We can conclude that

[tex]\angle B+130=180[/tex]

[tex]\angle B=180-130[/tex]

[tex]\angle B=50[/tex]

The sum of the interior angles in a triangle is 180 degrees. This is because a triangle is a polygon with three sides and three angles, and the sum of the angles in any polygon can be found by using the formula:

sum of interior angles = (n - 2) x 180 degrees

Note: n is the number of sides.

A triangle has 3 sides. So substituting 3 in for n gives us

(3 - 2) x 180 degrees = 180 degrees

So the sum of the interior angles in a triangle is always 180 degrees.

[tex]x\textdegree=180\textdegree-75\textdegree-50\textdegree\\x\textdegree=55\textdegree[/tex]

The fraction is given as follows:

8.3/10.3.

The fraction is modeled as follows:

x/y.

In which:

From the features of the problem, a system of equations is built to identify the variables.

If the numerator of a fraction is multiplied by 4 and the denominator is reduced by 2,the result is 4, hence the first equation is of:

4x/(y - 2) = 4.

Hence:

4x = 4(y - 2)

4x = 4y - 8

x = y - 2.

If the numerator of the fraction is increased by 15 and 2 subtracted from the double of the denominator, the result is 5/4, hence the second equation is of:

(x + 15)/(2y - 2) = 5/4.

We know that x = y - 2, hence the value of y is obtained as follows:

(y + 13)/(2y - 2) = 5/4.

5(2y - 2) = 4(y + 13)

10y - 10 = 4y + 52

6y = 62

y = 62/6

y = 10.3.

Then the value of x is of:

x = y - 2

x = 10.3 - 2

x = 8.3.

(b) y_p is -4x

(c) y_p is -4x + 7

(d) y_p is 8x + (7/2)

To find a particular solution to a differential equation by inspection - is to assume a trial function that looks like the non-homogeneous part of the differential equation.

(a) Given y'' + 2y = 14.

Because the no non-homogeneous part of the differential equation, 14 is a constant, our trial function will be a constant too.

Let A be our trial function:

We need our trial differential equation y''_p + 2y_p = 14

Now, we differentiate y_p = A twice, to obtain y'_p and y''_p that will be substituted into the differential equation.

y'_p = 0

y''_p = 0

Substitution into the trial differential equation, we have.

0 + 2A = 14

A = 6/2 = 7

Therefore, the particular solution, y_p = A is 7

(b) y'' + 2y = −8x

Let y_p = Ax + B

y'_p = A

y''_p = 0

0 + 2(Ax + B) = -8x

2Ax + 2B = -8x

By inspection,

2B = 0 => B = 0

2A = -8 => A = -8/2 = -4

The particular solution y_p = Ax + B

is -4x

(c) y'' + 2y = −8x + 14

Let y_p = Ax + B

y'_p = A

y''_p = 0

0 + 2(Ax + B) = -8x + 14

2Ax + 2B = -8x + 14

By inspection,

2B = 14 => B = 14/2 = 7

2A = -8 => A = -8/2 = -4

The particular solution y_p = Ax + B

is -4x + 7

(d) Find a particular solution of y'' + 2y = 16x + 7

Let y_p = Ax + B

y'_p = A

y''_p = 0

0 + 2(Ax + B) = 16x + 7

2Ax + 2B = 16x + 7

By inspection,

2B = 7 => B = 7/2

2A = 16 => A = 16/2 = 8

Using trigonometric identity, the value of the expressions are (Cosx + Cos5x)/2 + Sin3x.Cosx, √3/2, √3/2 and -√3/2

To solve this problem, we need to apply trigonometric identity;

1.

Cos2x · Cos3x - Sinax. Sin3x:

Using the identity Cos(A - B) = CosA.CosB + SinA.SinB, we can write:

Cos2x · Cos3x = (Cos(2x - 3x) + Cos(2x + 3x))/2 = (Cos(-x) + Cos(5x))/2 = (Cosx + Cos5x)/2

So the expression becomes:

(Cosx + Cos5x)/2 - Sinax. Sin3x

Using the identity Sin(A - B) = SinA.CosB - CosA.SinB, we can write:

Sinax. Sin3x = (Sin(ax - 3x) - Sin(ax + 3x))/2 = (Sin(-2x) - Sin(4x))/2 = (-Sin2x - Sin4x)/2

So the expression becomes:

(Cosx + Cos5x)/2 + (Sin2x + Sin4x)/2

Using the identity SinA + SinB = 2.Sin((A+B)/2).Cos((A-B)/2), we get:

(Sin2x + Sin4x)/2 = Sin3x.Cosx

Therefore, the expression simplifies to:

(Cosx + Cos5x)/2 + Sin3x.Cosx

2.

Sinzx Cosx+Cosex Sinx:

Using the identity Sin(A + B) = SinA.CosB + CosA.SinB, we can write:

Sinzx Cosx+Cosex Sinx = Sin(x + z)

So the expression is equivalent to Sin(x + z).

3.

Sın 85° Cos25°- Cos 85°. Sin 25°:

We can use the identity Sin(A - B) = SinA.CosB - CosA.SinB:

Sin 85° Cos25°- Cos 85°. Sin 25° = Sin(85° - 25°) = Sin60° = √3/2

4.

Cos 160°. Cos10° + Sin160°. Sin10°:

We can use the identity Cos(A - B) = CosA.CosB + SinA.SinB:

Cos 160°. Cos10° + Sin160°. Sin10° = Cos(160° - 10°) = Cos150° = -√3/2

The ages of Gregory and Janet are 10 and 16 years respectively.

Gregory is six years younger than Janet. 7 years ago, Janet was thrice as old as Gregory. Therefore, the ages of Gregory and Janet are as follows:

Let

x = age of Janet

Gregory age = x - 6

x - 7 = 3(x - 6 - 7)

Hence,

x - 7 = 3(x - 13)

x - 7 = 3x - 39

x - 3x = -39 + 7

-2x = -32

Overall, building a theory is a complex process that requires careful planning, attention to detail, and a willingness to remain open to alternative explanations and interpretations.

An important first step when building a theory is to formulate a clear and testable research question or hypothesis. A research question or hypothesis is a statement that suggests a relationship between two or more variables, and it guides the development of the theory. The research question or hypothesis should be specific, measurable, and falsifiable, meaning that it can be tested and potentially proven false through empirical research. Once a clear research question or hypothesis has been formulated, the researcher can then begin to gather and analyze data to support or refute the theory.

Another important first step when building a theory is to conduct a comprehensive review of existing literature and research in the field. This review helps the researcher to identify gaps or inconsistencies in current knowledge and to develop a clear understanding of the state of the field. This step can also help the researcher to refine their research question or hypothesis, as well as to identify potential variables and relationships that may be relevant to the theory.

Another important step when building a theory is to select an appropriate research design and methodology that will allow for the systematic collection and analysis of data. The research design should be aligned with the research question or hypothesis, and should enable the researcher to collect high-quality data that can be analyzed using appropriate statistical or qualitative methods.

In addition, it is important to be mindful of potential biases that can impact the development of a theory, such as confirmation bias or researcher bias. It is important for the researcher to be objective and to consider all possible explanations for their data, rather than solely seeking out evidence that supports their hypothesis or preconceived ideas.
