The independent set in a graph is a set of vertices that contain no edges. So, no neighboring vertices are included. The max independent set problem is to get an independent set of maximum size in graph G.

The solution for this question is discussed below:

a) The integer linear program for the max independent set problem is as follows:

maximize ∑x_i Subject to: x_i+x_j ≤ 1 {i,j} ∈ E;x_i ∈ {0, 1} ∀i. The variable x_i can represent whether the ith vertex is in the independent set. It can take on two values, either 0 or 1.

b) The LP relaxation for the max independent set problem is as follows:

Maximize ∑x_iSubject to:

xi+xj ≤ 1 ∀ {i, j} ∈ E;xi ≥ 0 ∀i. The variable xi can take on fractional values in the LP relaxation.

c) The family of graphs is as follows:

Consider a family of graphs G = (V, E) defined as follows. The vertex set V has n = 2^k vertices, where k is a positive integer. The set of edges E is defined as {uv:u, v ∈ {0, 1}^k and u≠v and u, v differ in precisely one coordinate}. It can be shown that the size of the max independent set is n/2. Using LP, the value can be determined. LP provides a value of approximately n/4. Therefore, the ratio LP-OPT/OPT is at least c/4. Therefore, the ratio is in for a constant c>0.

d) The size of a max-independent set is equivalent to the number of vertices minus the minimum vertex cover size.

e) The 2-approximation algorithm for vertex cover implies a 2-approximation algorithm for the max independent set.

(a) The orthogonal projection Ps: V + S from V onto S is a linear map. To prove this, we need to show that (au + Bu) - (a Ps(u) + BPs(v)) is orthogonal to S, where a and b are scalars, u and v are vectors in V, and Ps(u) and Ps(v) are the orthogonal projections of u and v onto S, respectively. (b) Assuming {V1, V2, ..., Vn} is an orthonormal basis for V and {V1, V2, ..., Vk} spans S, we need to find the matrix representation of Ps with respect to this basis.

(a) To show that Ps: V + S from V onto S is a linear map, we need to verify that it satisfies the properties of linearity. Let u and v be vectors in V, and let a and b be scalars. The orthogonal projection of u onto S is Ps(u), and the orthogonal projection of v onto S is Ps(v). We want to show that (au + Bu) - (a Ps(u) + BPs(v)) is orthogonal to S. To do this, we can show that their inner product with any vector in S is zero. Since the inner product is linear, we can distribute and factor out scalars to prove that (au + Bu) - (a Ps(u) + BPs(v)) is orthogonal to S. Therefore, Ps is a linear map.

(b) Assuming {V1, V2, ..., Vn} is an orthonormal basis for V, we can represent the vector u as a linear combination of the basis vectors: u = a1V1 + a2V2 + ... + anVn. The orthogonal projection of u onto S, Ps(u), is given by the sum of the projections of u onto each basis vector of S: Ps(u) = Ps(a1V1) + Ps(a2V2) + ... + Ps(anVn). Since the basis {V1, V2, ..., Vk} spans S, we only need to consider the projections of u onto the first k basis vectors. The matrix representation of Ps with respect to this basis is obtained by writing down the coefficients of the projections as entries in a matrix. Each column of the matrix represents the projection of the corresponding basis vector onto S.

To sketch the region enclosed by the given curves y = x and y = 1/4x, with the restriction 0 ≤ x ≤ 25, we can start by plotting the two curves on a coordinate plane and shading the region between them.

The curve y = x is a straight line passing through the origin (0, 0) and has a slope of 1. The curve y = 1/4x is also a straight line passing through the origin, but with a slope of 1/4.

First, let's plot the line y = x:

When x = 0, y = 0

When x = 25, y = 25

Plotting these two points and drawing a line passing through them will give us the line y = x.

Next, let's plot the line y = 1/4x:

When x = 0, y = 0

When x = 25, y = 25/4 = 6.25

Plotting these two points and drawing a line passing through them will give us the line y = 1/4x.

Now, we need to shade the region between these two curves. Since the restriction is 0 ≤ x ≤ 25, we only need to consider the region between x = 0 and x = 25.

The region will be bounded by the curves y = x and y = 1/4x.

Here is a rough sketch of the region enclosed by the given curves:

       | \

       |  \        y = 1/4x

       |       \

The shaded region is the area enclosed by the curves y = x and y = 1/4x, with x ranging from 0 to 25.

Step-by-step explanation:

Two rays with a common endpoint form an angle. An angle is defined as a geometric figure formed by two rays that share a common endpoint. In other words, an angle is formed when two rays emanating from a common point, and this common point is known as the vertex.

The rays are the sides of the angle, and the angle is measured in degrees. Angles have different measures, ranging from 0 degrees to 360 degrees. The two rays that make up an angle are also called the sides or arms of the angle. The angle is measured in degrees, and the size of the angle depends on the distance between the two sides of the angle that meet at the vertex.

In geometry, an angle can be named in different ways, depending on the context in which it is being used. Angles are essential in mathematics, physics, and other scientific fields, where they are used to measure the rotation of an object, determine the direction of an object, and in other applications involving rays and lines.

He expands the flower bed to have area \(\dfrac{75}4\) square feet.

Now, area on larger flower bed  for every square foot of the smaller flower bed = (area of larger bed) ÷ (area of smaller bed)

\(= \dfrac{75}{4}\div\dfrac{25}{4}=\dfrac{75}{4}\times\dfrac{4}{25}=\dfrac{3}{1}\)

We have the function N(x) = 20x - (10x + n) models the number of sweaters produced where n is a constant.

Since 500 balls of wool were used to produce 4000 sweaters. To find the value of n, substitute x = 500 and N = 4000 into the function. That is:

N(x) = 20x - (10x + n)

4000 = 20(500) - (10(500) + n)

4000 = 10000 - 5000 - n

4000 = 5000 - n

n = 5000 - 4000

n = 1000

In order to test the given hypothesis, we need to compare the test statistic (Z) with the critical value (Z alpha), where alpha is the level of significance. Since the alternative hypothesis states that mu1 - mu2 is greater than 0, we are interested in the right-tailed test.

This means that we need to find the critical value for the upper tail area under the standard normal distribution, which corresponds to the level of significance.

The null hypothesis will be rejected if the test statistic (Z) is greater than the critical value (Z alpha). Therefore, the correct option is (b) > = z alpha. This means that if the calculated value of Z is greater than or equal to the critical value of Z alpha, we can reject the null hypothesis in favor of the alternative hypothesis at the given level of significance.

It's important to note that the value of sigma is known in this case, which means that we can use the standard normal distribution to calculate the critical value and the test statistic. In summary, we reject the null hypothesis if Z is greater than or equal to the critical value Z alpha, which corresponds to the level of significance alpha for a right-tailed test.

a) To calculate the pressure at 12 hours of shut-in:

substitute the given values into the pressure buildup equation and solve for P(t=12).

b) Superposition in time is used in pressure buildup analysis by adding or summing the responses of multiple transient tests to analyze and interpret reservoir behavior and properties.

We have,

a) To calculate the pressure in the production well at 12 hours of a shut-in, we can use the equation for pressure transient analysis during shut-in periods, known as the pressure buildup equation:

P(t) = Pi + (Q / (4πKh)) * log((0.14ϕμCt(t + Δt)) / (Bo(ΔP + Δt)))

Where:

P(t) = Pressure at time t

Pi = Initial reservoir pressure

Q = Flow rate

K = Permeability

h = Reservoir thickness

ϕ = Porosity

μ = Viscosity

Ct = Total compressibility

t = Shut-in time (12 hours)

Δt = Time since the start of the flow period

Bo = Oil formation volume factor

ΔP = Pressure drop during the flow period

Given:

Pi = 3100 psi

Q = 200 STB/day

K = 45 md

h = 60 ft

ϕ = 15%

μ = 1.2 cp

Ct = 15x10^-6 psi^-1

Bo = 1.3 bbl/STB

t = 12 hours

Δt = 48 hours

ΔP = Pi - P(t=Δt) = Pi - (Q / (4πKh)) * log((0.14ϕμCt(Δt + Δt)) / (Bo(ΔP + Δt)))

Substituting the given values into the equation:

ΔP = 3100 - (200 / (4π * 45 * 60)) * log((0.14 * 0.15 * 1.2 * 15x\(10^{-6}\) * (48 + 48)) / (1.3 * (3100 - (200 / (4π * 45 * 60)) * log((0.14 * 0.15 * 1.2 * 15 x \(10^{-6}\) * (48 + 48)) / (1.3 * (0 + 48))))))

After evaluating the equation, we can find the pressure in the production well at 12 hours of shut-in.

b) Superposition in time is a principle used in pressure transient analysis to analyze and interpret pressure build-up tests.

It involves adding or superimposing the responses of multiple transient tests to simulate the pressure behavior of a reservoir.

The principle of superposition states that the response of a reservoir to a series of pressure changes is the sum of the individual responses to each change.

Superposition allows us to combine the information obtained from multiple tests and obtain a more comprehensive understanding of the reservoir's behavior and properties.

It is a powerful technique used in reservoir engineering to optimize production strategies and make informed decisions regarding reservoir management.

Thus,

a) To calculate the pressure at 12 hours of shut-in:

substitute the given values into the pressure buildup equation and solve for P(t=12).

g(x) = (x/2)^2

Step-by-step explanation:

if we look at the Y values for each point they remain the same, however the X values change, which tells us that the X variable is being 'tampered' with.

to find the scale factor, we divide 4/2, and we get 2.

so g(x) = (x/2)^2

remember that when applying a scale factor to the X value the effect will be inversed, so we multiply the X value with 1/2. you can use desmos to double check.
