Let 8 denote the minimum degree of any vertex of a given graph, and let A denote the maximum degree of any vertex in the graph. Suppose you know that a certain graph has seven vertices, and that 8 = 3 and Δ= 5. (a) Show that this graph must contain at least 12 edges. (b) What is the largest number of edges possible in this graph?

Answers

For a graph with seven vertices, a minimum degree of 3 (8 = 3), and a maximum degree of 5 (Δ = 5), it can be shown that the graph must contain at least 12 edges. The largest number of edges possible in this graph is determined by the Handshaking Lemma, which states that the sum of the degrees of all vertices in a graph is equal to twice the number of edges.

(a) To show that the graph must contain at least 12 edges, we can use the Handshaking Lemma. The sum of the degrees of all vertices in the graph is equal to twice the number of edges. In this case, with seven vertices and a minimum degree of 3, the sum of the degrees is at least 7 * 3 = 21. Therefore, the minimum number of edges is 21/2 = 10.5, which rounds up to 11. So the graph must contain at least 11 edges, but since the number of edges must be an integer, it must be at least 12.

(b) The largest number of edges possible in this graph can be determined by considering the maximum degree. In this case, the maximum degree is 5. Since the sum of the degrees of all vertices is equal to twice the number of edges, the sum of the degrees is at most 7 * 5 = 35. Therefore, the largest possible number of edges is 35/2 = 17.5, which rounds down to 17. So the largest number of edges possible in this graph is 17.

An airplane is on a heading of 170 degrees to a vacation island, and is cruising at 250km/hr. It is encountering a wind blowing from the south/west at 50 km/hr.

A. Draw a "logical" vector diagram of "our" flight to the "secret" island.

B. Determine the aircraft’s ground velocity (magnitude and direction and standard bearing). Round your final answer to 1 decimal.

C. If the entire flight took about 5 hours, how far is the vacation island from the airport of departure?

Answers

A) Logical vector diagram of the flight is drawn below. B) The aircraft's ground velocity is approximately 260.2 km/hr at a bearing of -153.7°. C) The vacation island is approximately 1301 kilometers from the airport of departure.

A.  a logical vector diagram of the flight is given in image.

B. To determine the aircraft's ground velocity, we need to find the resultant vector of the aircraft's velocity and the wind vector. We can use vector addition to calculate this:

Aircraft's velocity = 250 km/hr at a heading of 170°

Wind velocity = 50 km/hr at a heading of 270° (since it's blowing from the south/west)

To add these vectors, we need to resolve them into their horizontal (x) and vertical (y) components:

Aircraft's velocity:

[tex]V_x[/tex] = 250 km/hr * cos(170°)

[tex]V_{y}[/tex] = 250 km/hr * sin(170°)

Wind velocity:

[tex]V_x[/tex]_wind = 50 km/hr * cos(270°)

[tex]V_y[/tex]_wind = 50 km/hr * sin(270°)

Now, we can add the horizontal and vertical components separately:

[tex]V_{x} total = V_x + V_{x}wind\\V_{y} total = V_y + V_{y}wind[/tex]

To find the magnitude and direction of the resultant vector, we can use the Pythagorean theorem and trigonometry:

Magnitude of the resultant vector (ground velocity):

[tex]V_{total} = \sqrt{V_x total^2 + V_y total^2}[/tex]

Direction of the resultant vector:

[tex]\theta = tan^{-1} 2(V_y total, V_xtotal)[/tex]

Let's calculate the values:

[tex]V_x[/tex] = 250 km/hr * cos(170°) ≈ -235.83 km/hr

[tex]V_y[/tex] = 250 km/hr * sin(170°) ≈ -62.85 km/hr

[tex]V_x[/tex]_wind = 50 km/hr * cos(270°) = 0 km/hr

[tex]V_y[/tex]_wind = 50 km/hr * sin(270°) ≈ -50 km/hr

[tex]V_x[/tex]_total = -235.83 km/hr + 0 km/hr = -235.83 km/hr

[tex]V_y[/tex]_total = -62.85 km/hr + (-50 km/hr) = -112.85 km/hr

[tex]V_{total}[/tex] =  [tex]\sqrt{((-235.83 km/hr)^2 + (-112.85 km/hr)^2) }[/tex] ≈ 260.2 km/hr

θ = [tex]tan^{-1} 2(-112.85 km/hr, -235.83 km/hr)[/tex] ≈ -153.7°

The aircraft's ground velocity is approximately 260.2 km/hr at a bearing of -153.7°.

C. If the entire flight took about 5 hours, we can calculate the distance traveled by multiplying the ground velocity by the time:

Distance = Velocity * Time

Distance = 260.2 km/hr * 5 hours = 1301 km

The vacation island is approximately 1301 kilometers from the airport of departure.

A candle is formed in the shape of a cylinder. It has a diameter of 4 inches a d a height if 5 inches. Which measurement is closest to the total surface area of the candle in square inches

Answers

The closest measurement in square inches to the overall surface area of the candle is 87.92 square inches.

To find the total surface area of the candle, we need to calculate the lateral surface area (excluding the top and bottom) and then add the areas of the two circular bases.

1. Lateral Surface Area:

The formula for the lateral surface area of a cylinder is given by A = 2πrh, where r is the radius of the base and h is the height of the cylinder.

Given that the diameter of the candle is 4 inches, we can calculate the radius by dividing the diameter by 2:

Radius (r) = 4 inches / 2 = 2 inches

Height (h) = 5 inches

Using the formula, we can calculate the lateral surface area:

Lateral Surface Area = 2π(2 inches)(5 inches) = 20π square inches

2. Base Area:

The formula for the area of a circle is given by A = πr^2, where r is the radius of the circle.

Using the radius calculated earlier (r = 2 inches), we can calculate the area of each circular base:

Base Area = π(2 inches)^2 = 4π square inches

3. Total Surface Area:

To find the total surface area, we add the lateral surface area and the areas of the two circular bases:

Total Surface Area = Lateral Surface Area + 2(Base Area)

Total Surface Area = 20π + 2(4π) = 20π + 8π = 28π square inches

Approximating the value of π to 3.14, we can calculate the approximate total surface area:

Total Surface Area ≈ 28(3.14) = 87.92 square inches

Therefore, the closest measurement to the total surface area of the candle in square inches is 87.92 square inches.

Fill in the blank. The only solution of the initial-value problem y" + x2y = 0, y(0) = 0, y'(0) = 0 is y(x) = 0

Answers

The only solution of the initial-value problem y" + x^2y = 0, y(0) = 0, y'(0) = 0 is y(x) = 0, where y(x) represents the unknown function and x represents the independent variable.

To determine the solution of the initial-value problem, we consider the given second-order linear homogeneous differential equation y" + x^2y = 0 along with the initial conditions y(0) = 0 and y'(0) = 0.

First, we solve the differential equation by assuming a solution of the form y(x) = Ax^n, where A is a constant and n is an exponent to be determined. Substituting this into the differential equation, we obtain the characteristic equation n(n-1) + x^2 = 0.

Solving the characteristic equation, we find that the roots are n = 0, which corresponds to the solution y(x) = A, and n = 1, which corresponds to the solution y(x) = Bx. However, when we apply the initial conditions y(0) = 0 and y'(0) = 0, we find that both solutions are equal to zero.

Therefore, the only solution that satisfies both the differential equation and the initial conditions is y(x) = 0, indicating that the function y(x) is identically zero for all values of x.

Answers

The set of ordered pairs that represents a function from A to B is {(1, -1), (3, 2), (4, 0), (2, 1)}. A function from A to B is a relation that assigns a unique element from B to each element in A.

In order for a set of ordered pairs to represent a function, each element in A must have exactly one corresponding element in B.

Let's analyze each set of ordered pairs:

1. {(1, -1), (3, 2), (2, -2), (4, 0), (2, 1)}: This set is not a function because the element 2 in A is assigned two different elements (-2 and 1) in B. Each element in A should have a unique corresponding element in B.

2. {(1, 2), (4, 0), (2, 1)}: This set is a function because each element in A is assigned a unique element in B.

3. {(1, 1), (2, -2), (3, 0), (4, 2)}: This set is a function because each element in A is assigned a unique element in B.

4. {(1, 0), (2, 0), (3, 0), (4, 0)}: This set is a function because each elementin A is assigned a unique element (0) in B.

Based on the analysis, the set of ordered pairs that represents a function from A to B is {(1, -1), (3, 2), (4, 0), (2, 1)}.

1 (a) Find the Laurent series of the function (22-9)(2+3) centered at z = −3. 1 (b) Evaluate ſc[−3,3] (z²−9)(z+3) dz.

Answers

The simplification based on Laurent series of the function (22-9)(2+3) centered at z = −3

[((1/4)(3)⁴ + (2/3)(3)³ + (9/2)(3)² - 27(3))] - [((1/4)(-3)⁴ + (2/3)(-3)³ + (9/2)(-3)² - 27(-3))]

The given problem involves finding the Laurent series of a function centered at z = -3 and evaluating the integral of another function over a specific interval. The Laurent series simplifies to a constant term of 65.

(a) To find the Laurent series of the function (22-9)(2+3) centered at z = −3, we can expand the function in powers of (z + 3):

(22-9)(2+3) = (13)(5) = 65

Since there are no negative powers of (z + 3), the Laurent series of the function is simply the constant term:

f(z) = 65

(b) To evaluate the integral ſc[−3,3] (z²−9)(z+3) dz, we can first simplify the integrand:

(z² - 9)(z + 3) = (z - 3)(z + 3)(z + 3) = (z - 3)(z + 3)²

Now, let's integrate the simplified expression:

∫[(z - 3)(z + 3)²] dz

Expanding the expression:

∫[z³ + 6z² + 9z - 27] dz

Integrating each term:

(1/4)z⁴ + (2/3)z³ + (9/2)z² - 27z

Now, we can evaluate the integral over the given interval [−3, 3]:

∫[−3,3] (z²−9)(z+3) dz = [((1/4)z⁴ + (2/3)z³ + (9/2)z² - 27z)] evaluated from z = -3 to z = 3

Substituting the upper and lower limits into the expression and simplifying, we get:

[((1/4)(3)⁴ + (2/3)(3)³ + (9/2)(3)² - 27(3))] - [((1/4)(-3)⁴ + (2/3)(-3)³ + (9/2)(-3)² - 27(-3))]

Find the minimum of the Brown's badly scaled function using Powell's method. f(x) = (x₁ - 10^6)² + (x₂ − 2 × 10^-6)² + (x₁x₂ - 2)²

Answers

The minimum of Brown's badly scaled function, f(x) = (x₁ - 10^6)² + (x₂ − 2 × 10^-6)² + (x₁x₂ - 2)², can be found using Powell's method.

Powell's method is an optimization algorithm used to find the minimum of a function. It is an iterative method that searches for the minimum by successively approximating the direction of the minimum along each coordinate axis.

To apply Powell's method to find the minimum of Brown's badly scaled function, we start with an initial guess for the minimum point. Then, we iteratively update the guess by evaluating the function at different points and adjusting the guess based on the obtained results.

The iterative process continues until a convergence criterion is met, indicating that the minimum has been sufficiently approximated. The final guess represents the minimum point of the function.

By applying Powell's method to Brown's badly scaled function, we can determine the coordinates of the minimum point, which correspond to the values of x₁ and x₂ that minimize the function. The specific values of x₁ and x₂ will depend on the initial guess and the convergence criteria used in the optimization process.

A particular manufacturing design requires a shaft with a diameter of 20.000 mm, but shafts with diameters between 19.987 mm and 20.013 mm are acceptable. The manufacturing process yields shafts with diameters normally distributed, with a mean of 20.003 mm and a standard deviation of 0.005 mm. Complete parts (a) through (d) below. a. For this process, what is the proportion of shafts with a diameter between 19.987 mm and 20.000 mm?

Answers

Using area under normal curve and z-score, approximately 21.32% of shafts have a diameter between 19.987 mm and 20.000 mm.

What is the proportion of shafts with a diameter between 19.987mm and 20.000mm?

To find the proportion of shafts with a diameter between 19.987 mm and 20.000 mm, we need to calculate the probability that a randomly selected shaft falls within this range.

Given that the diameters of the shafts are normally distributed with a mean of 20.003 mm and a standard deviation of 0.005 mm, we can use the properties of the normal distribution to determine the desired proportion.

To calculate this proportion, we need to find the area under the normal curve between the values of 19.987 mm and 20.000 mm.

Let's denote the random variable X as the diameter of the shafts. We want to find P(19.987 ≤ X ≤ 20.000).

To do this, we can standardize the values by converting them to z-scores using the formula:

z = (x - μ) / σ

where x is the value, μ is the mean, and σ is the standard deviation.

For 19.987 mm:

z₁ = (19.987 - 20.003) / 0.005

For 20.000 mm:

z₂ = (20.000 - 20.003) / 0.005

We can then use a standard normal distribution table or calculator to find the corresponding probabilities associated with these z-scores.

Using a standard normal distribution table, we find that P(Z ≤ z₁) ≈ 0.2119 and P(Z ≤ z₂) ≈ 0.4251.

To find the proportion of shafts between 19.987 mm and 20.000 mm, we subtract the probabilities:

P(19.987 ≤ X ≤ 20.000) = P(Z ≤ z₂) - P(Z ≤ z₁) ≈ 0.4251 - 0.2119

P(19.987 ≤ X ≤ 20.000) ≈ 0.2132

Distilled water on january 6, year 1, bulldog co. purchased 34% of the outstanding stock of gator co. for $212,000. gator co. paid total dividends of $24,000 to all shareholders on june 30. gator had a net loss of $56,000 for year 1. journalize bulldog's purchase of the stock, receipt of the dividends, and the adjusting entry for the equity loss in gator co. stock. compute the balance of investment in gator co. stock on december 31, year 1. how does valuing an investment under the equity method differ from valuing an investment at fair value? Prove the following? If light that is initially natural and of flux density Ii passes through two sheets of HN-32 whose transmission axes are parallel, what will be the flux density of the emerging beam? 8.11 What will be the irradiance of the emerging beam if the ana- lyzer of the previous problem is rotated 30? A mass-spring oscillator has a mass of 2 kg, a spring constant of 34 N/m and a damping constant of 4 Ns/m. It is stretched to a displacement of 10 m and released from rest. a. Assuming there are no external forces, model the spring's displacement as a function of time. Graph your answer and describe its asymptotic behavior in a sentence. b. Now assume that at t seconds, there is an external force (in Newtons) given by Fexr(t) = 130 cos(t). (Assume the external force is oriented parallel to the spring) Write an initial value problem describing the motion of the system. c. Solve the above system to write the displacement as a function of time. Graph your answer and describe its asymptotic behavior in a sentence. d. Repeat parts b and c, assuming there is no friction. Carbon dioxide emissions are one of the major causes of air pollution. Whenever a firm emits carbon dioxide due to its business activities, it creates externalities for others.(a) Should carbon dioxide emissions be banned completely from an economic perspective? "Completely banned" means no firms can emit carbon dioxide. Please explain.Consider a world with three firms. Carbon dioxide emissions by different firms are different, and the cost of reducing emissions varies among them as shown in the following table:Firm Emission of CO2 Cost of Reducing Emission by 1 UnitA 50 units $20B 30 units $30C 40 units $40Now, suppose all governments in the world agree to use emission permits to control the total amount of carbon dioxide to be emitted, and all governments in the world want to reduce the emission to 60 units. As a result, 60 permits will be issued and the holder of 1 emission permit can emit 1 unit of carbon dioxide legally.(b) If each firm will be given 20 permits, will voluntarily trade happen among the firms? Describe who are buyers and who are sellers and how many permits will be traded among them.(c) From the perspective of economic efficiency, should the permits for the emission of carbon dioxide be distributed equally among firms (that is each firm receives 20 permits) or by using auction (which is buyers willing to pay the highest price will get the permits)? Explain. Problem 3. Determine whether the statement is true or false. Prove the statement directly from definitions if it is true, and give a counterexample if it is false. (1) There exists an integer m 23 such that 6m +27 is prime. (2) For all integers a and b, if a divides b, then a divides b. (3) If m is an odd integer, then 3m + 7m +12 is an even integer. 5.
