Answer: \(77.6 < \mu < 87.4\)

Step-by-step explanation:

The detailed explanation is attached below.

The length of each leg of a right triangle given that one angle is 22° and the length of the hypotenuse is 10 inches are 3.75 and 9.27 inches respectively.

In order to determine the length of the opposite side and adjacent side, we would apply both the cosine and sine trigonometry ratio because the given side lengths represent the hypotenuse of a right-angled triangle.

cos(θ) = Adj/Hyp

Where:

By substituting the parameters into the sine trigonometry ratio formula, we have the following;

sin(θ) = Opp/Hyp

sin(22) = y/10

y = 10sin(22)

y = 3.75 inches.

For the adjacent side, we have:

cos(θ) = Adj/Hyp

cos(22) = x/10

x = 10cos(22)

x = 9.27 inches.

(–2, 6) are the points that justify the shaded area

We can substitute the values of x and y from each point into the inequality and check if the inequality is satisfied or not.

Let's check each point:

For points (12, 6):

\((y+1)^2/6 -(x+2)^2/24\\ = (6+1)^2/6 - (12+2)^2/24 \\= 49/6 - 196/3 \\= -57.33\)

Here, the value of the expression is less than 1, so this point does not justify the shaded area.

For points (–2, 6):

\((y+1)^2/6 -(x+2)^2/24\\ = (6+1)^2/6 - (-2+2)^2/24 \\= 49/6\)

Here, the value of the expression is greater than or equal to 1, so this point does justify the shaded area.

For points (8, –6):

\((y+1)^2/6 -(x+2)^2/24 \\= (-6+1)^2/6 - (8+2)^2/24 \\= 25/6-100/24\)

Here, the value of the expression is greater than or equal to 1, so this point does not justify the shaded area.

For point (–1, –2):

\((y+1)^2/6 -(x+2)^2/24 \\= (-2+1)^2/6 - (-1+2)^2/24 \\= 1/6 - 1/24 \\= 1/8\)

Here, the value of the expression is less than 1, so this point does not justify the shaded area.

Therefore, the points that justify the shaded area are (–2, 6).

Given values:

Substitute the given values into the formula:

The heat of reaction at 250 °C for the given reaction is -318.6 kJ/mol.

To determine the heat of reaction at 250 °C for the given reaction:

N2(g) + C2H2(g) → 2HCN(g)

We can use the heats of formation and heat capacities provided. The heat of reaction can be calculated using the equation:

ΔH = ΣnΔHf(products) - ΣmΔHf(reactants)

where ΔH is the heat of reaction, ΣnΔHf(products) is the sum of the heats of formation of the products (multiplied by their coefficients), and ΣmΔHf(reactants) is the sum of the heats of formation of the reactants (multiplied by their coefficients).

Given the heats of formation at 25 °C:

ΔHf(HCN) = -45.9 kJ/mol
ΔHf(C2H2) = 226.8 kJ/mol
ΔHf(N2) = 0 kJ/mol

We need to convert the heat capacities from functions of temperature to specific values at 250 °C. To do this, we substitute T = 250 °C (523 K) into the given heat capacity equations.

Cp(HCN) = 21.9 + 0.0606T - 4.86 × 10^(-5)T^2 + 1.82 × 10^(-8)T^3
Cp(C2H2) = 26.8 + 0.0758T - 5.01 × 10^(-5)T^2 + 1.41 × 10^(-8)T^3
Cp(N2) = 31.2 + 0.0136T - 2.68 × 10^(-5)T^2 + 1.17 × 10^(-8)T^3

Substituting T = 523 K into these equations, we can calculate the heat capacities at 250 °C:

Cp(HCN) = 21.9 + 0.0606(523) - 4.86 × 10^(-5)(523)^2 + 1.82 × 10^(-8)(523)^3
Cp(C2H2) = 26.8 + 0.0758(523) - 5.01 × 10^(-5)(523)^2 + 1.41 × 10^(-8)(523)^3
Cp(N2) = 31.2 + 0.0136(523) - 2.68 × 10^(-5)(523)^2 + 1.17 × 10^(-8)(523)^3

Now, we can calculate the heat of reaction at 250 °C using the formula:

ΔH = ΣnΔHf(products) - ΣmΔHf(reactants)

Substituting the given values:

ΔH = 2(ΔHf(HCN)) - (ΔHf(C2H2) + ΔHf(N2))

ΔH = 2(-45.9 kJ/mol) - (226.8 kJ/mol + 0 kJ/mol)

Simplifying:

ΔH = -91.8 kJ/mol - 226.8 kJ/mol

ΔH = -318.6 kJ/mol

Therefore, the heat of reaction at 250 °C for the given reaction is -318.6 kJ/mol.

We can see here that using the converse of  the Triangle Proportionality Theorem to verify if line MQ || line PR, we see that they are actually parallel. Thus, 6/8 = 12/16 = 3/4.

The Triangle Proportionality Theorem (also known as the Side Splitter Theorem) is a theorem in geometry that relates the proportions of the sides of two triangles that are formed when a line is drawn parallel to one side of a triangle.

The theorem states that if a line is drawn parallel to one side of a triangle, then it divides the other two sides into proportional segments.

That is, if a line is drawn parallel to side AB of triangle ABC, intersecting sides AC and BC at points D and E respectively, then:

AD/DC = BE/EC

We see here that taking the ratio of the sides, we have:

6/8 = 3/4

12/18 = 3/4

If a planar polygon has all the line segments connecting any given pair of its points, it is said to be convex pentagon.

Properties of a Convex Polygon are-

Calculation for the measure of angle D.

The sum of the interior angles  = 540°

Let A, B , C  =   D - 40

And let  E  = D

So we have

A + B + C + D + E  = 540

(D - 40) + (D - 40)  + (D - 40)  + D + D  =  540

5D  - 120  = 540

5D = 660

D = 660 / 5

The slope =2 and y-intercept = -3.

What is slope?

Calculated using the slope of a line formula, the ratio of "vertical change" to "horizontal change" between two different locations on a line is determined. The difference between the line's y and x coordinate changes is known as the slope of the line.Any two distinct places along the line can be used to determine the slope of any line.

Here let us take two points \((x_1,y_1)=(1.5,0) , (x_2,y_2)=(0,3)\) .

Now using slope formula then,

Slope m = \(\frac{y_2-y_1}{x_2-x_1}\)

=> m = \(\frac{3-0}{0-1.5} = \frac{3}{-1.5}=2\)

Now using equation formula then,

=> \(y-y_1=m(x-x_1)\)

=> y-0=2(x-1.5)

=> y = 2x-3

Here y=mx+b, where b= y-intercept.

When designing a new class, the rules that dictate how the instance variables are used are called the "class invariants."

Class invariants are conditions or properties that must hold true for all instances of a class throughout its lifetime. They define the constraints and guarantees regarding the state and behavior of the objects of that class.

Class invariants typically involve restrictions or requirements on the values of instance variables and the relationships between them. They ensure the consistency and integrity of the object's state, providing a set of rules that must be maintained during the execution of methods and operations on the class.

By defining and enforcing class invariants, developers can establish the expected behavior of objects and prevent invalid or inconsistent states from occurring. Class invariants contribute to the overall correctness, reliability, and maintainability of object-oriented programs.

Elizabeth will take 9 hours and 45 minutes to catch up with Duane using the given speed-distance-time values.

The speed-distance-time relations are:

Speed = Distance/Time, Distance = Speed*Time, and Time = Distance/Speed.

The distance traveled by Duane on the bike at 14 miles per hour for 3 hours = 14*3 miles = 42 miles.

The time that Elizabeth takes to cover 42 miles jogging at 5 miles per hour = 42/5 hours = 8.4 hours.

The distance traveled by Duane in the extra time which Elizabeth took to reach his bike (8.4 - 3 = 5.4 hours) walking at 2 miles per hour = 2*5.4 = 10.8 miles.

Now, the distance between Elizabeth and Duane is 10.8 miles, before Elizabeth starts riding the bike.

Keeping the distance constant, we calculate the relative speed to calculate the time to cover this distance.

Relative speed = Elizabeth's speed - Duane's speed {As Elizabeth is moving towards Duane, that is, covering the distance but Duane is moving away from Elizabeth, that is, increasing the distance}.

or, Relative speed = 10 - 2 = 8 miles per hour.

Time taken to cover the distance = 10.8/8 = 1.35 hours.

Therefore, the total time taken by Elizabeth to catch up with Duane = 8.4 + 1.35 hours = 9.75 hours or 9 hours and 45 minutes.

However, the progression does not start at 0, so we will have to subtract 3, and then it would be 5n - 3. We're still not at the answer; this is because the first term starts at 1, not 0. We will have to account for that, so subtract the coefficient, or 5, from the whole expression. That would be 5n - 8, and that would be the answer.
