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.

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]

To find the units for the rate of change (rise over run), we need to determine the change in y (rise) divided by the change in x (run) for any two points in the table.

Let's choose the first and last points in the table, (5, $35) and (10, $70), respectively. The change in y is $70 - $35 = $35, and the change in x is 10 - 5 = 5. So the rate of change (rise over run) is:

rise/run = $35/5 = $7

Therefore, the best representation for the units of the rate of change is dollars per pound, as the rate of change indicates how much the price changes for every pound of coffee ordered. So the answer is (b) dollars per pound.

(a) The particular solution, y_p is 7

(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

The particular solution y_p = Ax + B

10 mL is equal to 2 teaspoons or 0.67 tablespoons. One teaspoon is equal to 5 mL, so to convert 10 mL to teaspoons, divide 10 by 5. One tablespoon is equal to 15 mL, so to convert 10 mL to tablespoons, divide 10 by 15.

10 mL is equal to 2 teaspoons (tsp) or 0.67 tablespoons (tbsp).

One teaspoon is equal to 5 mL, so to convert 10 mL to teaspoons, you can divide 10 by 5, which gives:

10 mL / 5 mL/tsp = 2 tsp

Therefore, 10 mL is equal to 2 teaspoons.

One tablespoon is equal to 15 mL, so to convert 10 mL to tablespoons, you can divide 10 by 15, which gives:

10 mL / 15 mL/tbsp = 0.67 tbsp

Therefore, 10 mL is equal to approximately 0.67 tablespoons.

Answer: To find the height of the flagpole, we can use the fact that the angles of depression and elevation are complementary angles, meaning that they add up to 90°.

Let's call the height of the flagpole "h". Then, we have:

h - 6 = h * tan(4°) (the height difference between Javier and the bottom of the flagpole)

and

h = 6 + h * tan(25°) (the height of the top of the flagpole as seen by Javier).

By substituting the first equation into the second, we can find h:

h = 6 + h * tan(25°)

h = 6 + h / tan(65°)

h * tan(65°) = 6 + h

h * tan(65°) - h = 6

h = 6 / (tan(65°) - 1)

Using a calculator, we find that h = approximately 43.3 feet. Rounding to the nearest foot, the height of the flagpole is 43 feet.

The Tracking Signal in Week 3 is -1.8.

The Tracking Signal in Week 3 can be calculated by using the following formula:

Tracking Signal = (Sum of Forecast Errors) / (Mean Absolute Deviation)

First, we need to calculate the forecast errors for each week:

Week 1 Forecast Error = Actual Demand - Forecast = 50 - 49 = 1
Week 2 Forecast Error = Actual Demand - Forecast = 54 - 56 = -2
Week 3 Forecast Error = Actual Demand - Forecast = 58 - 60 = -2

Next, we need to calculate the Mean Absolute Deviation (MAD):

MAD = (|1| + |-2| + |-2|) / 3 = (1 + 2 + 2) / 3 = 5 / 3 = 1.67

Finally, we can calculate the Tracking Signal:

Tracking Signal = (1 + -2 + -2) / 1.67 = -3 / 1.67 = -1.8

A cube is a three dimensional solid with six congruent square faces.

The expression the height and length dimensions of the rectangular prism as improper fractions, indicates that we get;

Height = (1 2/3) cm = (3 × 1 + 2)/3 cm = 5/3 cm

Length = (2 1/3) cm = (3 × 2 + 1)/3 cm = 7/3 cm

The denominators of the dimensions of the height, length and width of the rectangular prism are equivalent to 3. The edge length of the cube that can be used to fill the container should have a denominator that is a factor of 3.

The size of the cube that can be used to fill the container is therefore the cube with side length of 1/3 inches

The volume of the container = (5/3) in × (2/3) in × (7/3) in = 70/27 in³

The volume of the (1/3) inch cube = (1/3) in ×(1/3) in ×(1/3) in = 1/27 in³

The number of 1/3 inch cubes that fills the container = (70/27)/(1/27) = 70
