The height of the rectangle is 16.6 millimeters.

To find the height of a rectangle, we can use the formula for the perimeter of a rectangle, which states that the perimeter is equal to twice the sum of its length and width. In this case, the base of the rectangle is given as 15.8 millimeters, and the perimeter is given as 64.8 millimeters.

Let's denote the height of the rectangle as h. Using the formula, we can express the given information as:

Perimeter = 2 × (Base + Height)

Substituting the given values, we have:

64.8 = 2 × (15.8 + h)

To solve for h, we first simplify the equation by multiplying the values inside the parentheses:

64.8 = 2 × 15.8 + 2 × h

Next, we simplify further:

64.8 = 31.6 + 2h

Subtracting 31.6 from both sides:

64.8 - 31.6 = 2h

33.2 = 2h

To isolate h, we divide both sides by 2:

33.2/2 = h

16.6 = h

Given, n = 2000 registered UOM students sampled and x = 600 planned to register for the summer semester

We need to find the confidence interval estimate for the population proportion (to the nearest tenth of a percent). The formula for the confidence interval estimates for the population proportion (to the nearest tenth of a percent) is given below:

Confidence intervals estimate for the population proportion = x / n ± z(α/2) * √ ((p * q) / n)

Where, z (α/2) = z-score corresponding to the level of confidence = z (0.975) = 1.96 (for 95% level of confidence) p = sample proportion = x / np = 600 / 2000 = 0.3q = 1 - p = 1 - 0.3 = 0.7

Substitute the values in the above formula, we get Confidence interval estimate for the population proportion = 600 / 2000 ± 1.96 * √ ((0.3 * 0.7) / 2000) = 0.30 ± 0.027= 0.273 to 0.327

Therefore, the confidence interval estimates for the population proportion (to the nearest tenth of a percent) is 27.3% to 32.7%.

To satisfy the middle 44% of the market, the contractor should build houses with prices ranging from $238,983 to $254,618.

To find the minimum and maximum prices of houses that satisfy the middle 44% of the market, we need to determine the cutoff prices.

Given that the variable (prices of new one-family homes) is normally distributed with an average of $246,300 and a standard deviation of $15,000, we can use the standard normal distribution to find the cutoff values.

Step 1: Convert the desired percentile to a z-score.

The middle 44% of the market corresponds to (100% - 44%) / 2 = 28% on each tail.

Step 2: Find the z-scores corresponding to the desired percentiles.

Using a standard normal distribution table or statistical software, we can find that the z-score corresponding to an area of 28% is approximately -0.5545.

Step 3: Convert the z-scores back to the original prices using the formula:

[tex]z = (x - \mu) / \sigma[/tex]

For the minimum price:

-0.5545 = (x - 246300) / 15000

Solving for x:

x - 246300 = -0.5545 * 15000

x - 246300 = -8317.5

x = 238982.5

For the maximum price:

0.5545 = (x - 246300) / 15000

Solving for x:

x - 246300 = 0.5545 * 15000

x - 246300 = 8317.5

x = 254617.5

Rounding the minimum and maximum prices to the nearest dollar, we get:

Minimum price: $238,983

Maximum price: $254,618

Therefore, to satisfy the middle 44% of the market, the contractor should build houses with prices ranging from $238,983 to $254,618.

Answer:

6 m

Step-by-step explanation:

a = [tex]s^{2}[/tex]

36 = [tex]6^{2}[/tex]

Each side is 6 m.

Helping in the name of Jesus.

Answer:

6 meters (In the Name of Jesus, I am helping others, Amen).

Step-by-step explanation:

If a square has an area of 36 m², then the length of each side can be found by taking the square root of the area since the area of a square is equal to the length of one side squared.

So, we can find the length of each side of the square as follows:

Side length = √(Area)

Side length = √(36 m²)

Side length = 6 m

Therefore, the length of each side of the square is 6 meters.

Cpk measures the relationship between the process variability and the specification limits. If the process mean is not centered within the specification limits, reducing the standard deviation alone may not improve the Cpk.

a. False. It is possible for the Lower Control Limit (LCL) in an Xbar chart to be greater than the Upper Specification Limit (USL). The control limits in statistical process control (SPC) are based on the process variability, while specification limits are determined by customer requirements. If the process is in control but does not meet the customer's specifications, it is possible for the LCL to be greater than the USL.

b. False. Statistical Tolerancing generally offers higher First Time Yield (FTY) compared to Worst Case Tolerancing. Statistical Tolerancing takes into account the statistical distribution of the process and allows for better utilization of the allowable tolerance range, resulting in higher FTY. Worst Case Tolerancing, on the other hand, assumes extreme values for all variables, leading to lower FTY.

c. False. In Worst Case analysis, the probability of interference can be zero or non-zero, depending on the specific scenario. It is possible to have cases where the tolerances do not overlap and there is no interference, resulting in a probability of interference of 0%.

d. True. For sample sizes that are significantly larger than 30, the standard deviation (o) of the process can be approximated by the sample standard deviation (s) in Statistical Process Control (SPC). This approximation holds under the assumption of a normal distribution and large sample sizes where the Central Limit Theorem applies.

e. False. C charts are control charts used for monitoring the count or number of defects per unit. Cpk, on the other hand, is a capability index that measures the process capability to meet specifications. C charts and Cpk serve different purposes in Statistical Process Control (SPC) and are not directly comparable.

f. False. If Cpk < 0, it indicates that the process is not capable of meeting the specification limits. In this case, the process mean is not within the specification limits.

g. True. Design for Manufacturability (DFM) aims to reduce the number of assembly parts, which can help reduce opportunities for defects or occurrences of failure modes. By simplifying the design and reducing the number of parts, the overall Failure Detections (OFDs) can be reduced.

h. True. Defects in a multi-step manufacturing process are generally additive. Each step in the process has its own probability of generating defects, and as the product moves through the various steps, the defects can accumulate.

i. False. FTY (First Time Yield) is calculated as 1 minus DPU (Defects Per Unit). It is valid for DPU values ranging from 0 to 1. DPU values greater than 0.5 indicate a high defect rate, but the formula FTY = 1 - DPU is still applicable.

j. False. Reducing the standard deviation (o) of a process does not always increase the Cpk (Process Capability Index). Cpk measures the relationship between the process variability and the specification limits. If the process mean is not centered within the specification limits, reducing the standard deviation alone may not improve the Cpk. The process mean also needs to be adjusted to ensure that it falls within the specification limits to increase the Cpk value.

Yes, there exists an r x n parity-check matrix H such that GH^T = 0.

To show the existence of an r x n parity-check matrix H such that GH^T = 0, we need to construct H based on the given m x n encoding matrix G.

Let's first understand the structure of G. The encoding matrix G for a systematic linear block code with parameters (m, n) has the following form:

G = [I_m | P],

where I_m is the m x m identity matrix and P is an m x r matrix containing the parity-check bits. The identity matrix I_m represents the systematic part of the code, which directly maps the information bits to the codeword.

The matrix P represents the parity-check part of the code, which ensures that the codeword satisfies certain parity-check equations.

To construct the parity-check matrix H, we need to find a matrix such that when multiplied by G^T, the result is zero. In other words, we want H to satisfy the equation GH^T = 0.

Let's denote the rows of H as h_i, where 1 <= i <= r. Since GH^T = 0, each row h_i should satisfy the equation:

h_i * G^T = 0,

where "*" denotes matrix multiplication.

Expanding the above equation, we have:

[h_i | h_i * P^T] = 0,

where h_i * P^T represents the dot product of h_i and the transpose of matrix P.

Since the first m columns of G are an identity matrix I_m, we can write the above equation as:

[h_i | h_i * P^T] = [0 | h_i * P^T] = 0.

This implies that h_i * P^T = 0.

Therefore, to satisfy the equation GH^T = 0, we can construct H such that each row h_i is orthogonal to the matrix P. In other words, h_i should be a valid codeword of the dual code of the systematic linear block code generated by G.

To summarize, the existence of an r x n parity-check matrix H such that GH^T = 0 relies on constructing H such that each row h_i is orthogonal to the matrix P, i.e., h_i * P^T = 0. The dual code of the systematic linear block code generated by G provides valid codewords for H.

The statement "f(En F) = f(E) n f(F)" does not hold in general for all functions f: A → B and sets E, F ⊆ A.

The statement "f(En F) = f(E) n f(F)" does not hold in general for all functions f: A → B and sets E, F ⊆ A. To demonstrate this, let's consider a counterexample.

Counterexample:

Let A = {1, 2} be the domain, B = {1, 2, 3} be the codomain, and f: A → B be defined as follows:

f(1) = 1

f(2) = 2

Let E = {1} and F = {2}. Then, E ∩ F = ∅ (the empty set).

Now let's evaluate both sides of the equation:

f(E) = f({1}) = {1}

f(F) = f({2}) = {2}

f(En F) = f(∅) = ∅

We can see that {1} ∩ {2} = ∅, so f(E) ∩ f(F) = {1} ∩ {2} = ∅.

The endpoints of the t-distribution with 2.5% beyond them in each tail are: t* = ± 2.021.

In order to find the endpoints of the t-distribution with 2.5% beyond them in each tail, for samples of sizes n1= 14 and n2 = 28, given that samples are random and the distributions are normally distributed, we will use the t-distribution to answer this question.

The formula used to determine the endpoints of the t-distribution is given as follows:

t* = ± t(α/2, df),

where the degrees of freedom used are

df = n1 + n2 - 2

and

α = 0.025 (because we want 2.5% beyond the endpoints in each tail).

Substituting in the values of n1 and n2, we have df = 14 + 28 - 2 = 40.

Using a t-distribution table or a calculator, we can determine that the t-value for α/2 with 40 degrees of freedom is t(0.025/2, 40) = ± 2.021.

Therefore, the endpoints of the t-distribution with 2.5% beyond them in each tail are:

The number of distinct squares a chess knight can reach after n moves on an infinite chessboard can be determined using an induction argument and a formula.

The formula involves finding a pattern in the number of reachable squares as the number of moves increases.

Let's consider the base case where n = 0. When the knight hasn't made any moves, it is on a single square, so the number of reachable squares is 1.

Now, assume that for some positive integer k, the knight can reach F(k) distinct squares after k moves. We want to show that the knight can reach F(k+1) distinct squares after k+1 moves.

To reach F(k+1) distinct squares, the knight must be on a square that has adjacent squares from which it can make its next move. The knight can move to each of those adjacent squares in one move, and from there it can reach F(k) distinct squares. Therefore, the total number of distinct squares reachable after k+1 moves is F(k+1) = F(k) + 8, since the knight has 8 possible adjacent squares.

Using this recursive formula, we can find F(n) for any positive integer n. For example, F(1) = F(0) + 8 = 1 + 8 = 9, F(2) = F(1) + 8 = 9 + 8 = 17, and so on.

In summary, the number of distinct squares a chess knight can reach after n moves can be calculated using the formula F(n) = F(n-1) + 8, where F(0) = 1.

The mean function of the random process. X(t) is:μ(t) = E[X(t)] = (1/3) [sin (4πt + 2Ө) - sin (2πt + Ө)].

Given X(t) = A cos(wet + Ө), where the amplitude A is a uniformly distributed random variable over (-1, 2), while the phase Ө and the frequency we are constants.

To calculate the mean function of the random process, we know that the mean is defined as E[X(t)].

Therefore, E[X(t)] = E[A cos(wet + Ө)]

We know that A is uniformly distributed over (-1,2).

The probability density function of a uniform distribution over (a, b) is f(x) = 1/(b - a) if a ≤ x ≤ b and 0 otherwise.

Using this probability density function, the mean of A is given by E[A] = (2 + (-1))/2 = 0.5.

We can apply the Law of Total Probability to calculate E[X(t)] as follows:

E[X(t)] = E[A cos (wet + Ө)] = ∫cos (wet + Ө) f(A) dA (from -1 to 2) = ∫cos (wet + Ө) (1/3) dA (from -1 to 2) = (1/3) [sin (2wet + 2Ө) - sin (wet + Ө)] (from -1 to 2) = (1/3) [sin (4πt + 2Ө) - sin (2πt + Ө)].

Therefore, the mean function of X(t) is:μ(t) = E[X(t)] = (1/3) [sin (4πt + 2Ө) - sin (2πt + Ө)].

We can find the autocorrelation function of X(t) as follows: R (t1, t2) = E[X(t1) X(t2)] = E[A cos (wet1 + Ө)A cos (wet2 + Ө)].

The product of two cosine functions can be written in terms of the sum of the cosine and sine functions as follows: cos(x)cos(y) = (1/2)[cos (x + y) + cos (x - y)] sin (x)sin(y) = (1/2) [cos (x - y) - cos (x + y)]

Therefore, A cos (wet1 + Ө)A cos (wet2 + Ө) = (1/2)A² [cos (wet1 + wet2 + 2Ө) + cos (wet1 - wet2)] + (1/2)A² [cos (wet1 - wet2) - cos (wet1 + wet2 + 2Ө)]

We can find the expected value of this expression as follows: E[A cos(wet1 + Ө)A cos(wet2 + Ө)] = (1/2)E[A²] [cos(wet1 + wet2 + 2Ө) + cos(wet1 - wet2)] + (1/2)E[A²] [cos(wet1 - wet2) - cos(wet1 + wet2 + 2Ө)] = (1/3) [cos(wet1 + wet2 + 2Ө) + cos(wet1 - wet2)]

Therefore, R(t1, t2) = E[X(t1) X(t2)] = (1/3) [cos (wet1 + wet2 + 2Ө) + cos (wet1 - wet2)]

Sample Mean = (0.8 + 1.8 + 0.8 + 1.19 + 0.4) / 5 = 0.99

b. To calculate the sample standard deviation, we'll use the formula:

Sample Standard Deviation = √((Σ(x - x')²) / (n - 1))

where Σ represents the sum, x is each data point, x' is the sample mean, and n is the sample size. Let's calculate it:

Calculate the squared deviations:

(0.8 - 0.99)² = 0.0361

(1.8 - 0.99)² = 0.8281

(0.8 - 0.99)² = 0.0361

(1.19 - 0.99)² = 0.0441

(0.4 - 0.99)^2 = 0.3481

Calculate the sum of squared deviations:

Σ(x - x')² = 0.0361 + 0.8281 + 0.0361 + 0.0441 + 0.3481 = 1.2925

Calculate the sample standard deviation:

Sample Standard Deviation = √(Σ(x - x')² / (n - 1))

c. To construct a 90% confidence interval estimate for the population mean, we'll use the formula:

Confidence Interval = (x' - z*(σ/√n),x' + z*(σ/√n))

where x is the sample mean, z is the z-value corresponding to the desired confidence level (90% corresponds to z = 1.645 for a one-tailed interval), σ is the population standard deviation (which we don't have, so we'll use the sample standard deviation as an estimate), and n is the sample size.

Let's calculate the confidence interval:

Confidence Interval = (0.99 - 1.645*(0.568/√5), 0.99 + 1.645*(0.568/√5))

= (0.99 - 0.787, 0.99 + 0.787)

= (0.203, 1.777)

Therefore, the 90% confidence interval estimate for the population mean is (0.203, 1.777).

The probability that Jenny draws 4 consecutive blue balls from different bags is 1/64. The probability that after 5 draws she has not drawn from the orange bag is 1023/1024.

To compute the probability that the first 4 balls Jenny drew are blue, we need to consider the sequence of draws.

Since each bag is equally likely to be picked at each step, the probability of drawing a blue ball from the white bag is 5/20 = 1/4, and the probability of drawing a blue ball from the yellow bag is 10/20 = 1/2.

Therefore, the probability of drawing 4 consecutive blue balls is (1/4) * (1/2) * (1/4) * (1/2) = 1/64.

To compute the probability that after 5 draws Jenny has not drawn from the orange bag, we need to consider the possibilities for the first 5 draws.

Since Jenny starts from the white bag, there are two cases: either she draws 5 blue balls (all from the white and yellow bags) or she draws at least one non-blue ball.

The probability of drawing 5 consecutive blue balls is (1/4)^5 = 1/1024.

Therefore, the probability of not drawing from the orange bag after 5 draws is 1 - 1/1024 = 1023/1024.

The equation of the line parallel to y = 4x - 1 and passing through (-3, 7) is y = 4x + 19.

To find the equation of the line parallel to y = 4x - 1 and passing through (-3, 7), we know that parallel lines have the same slope. The given line has a slope of 4. Since the line y = x also needs to have a slope of 4, we can write its equation as y = 4x + b. To find the value of b, we substitute the coordinates (-3, 7) into the equation. Thus, 7 = 4(-3) + b, which simplifies to b = 19. Therefore, the equation of the line parallel to y = 4x - 1 and passing through (-3, 7) is y = 4x + 19.

To test the belief that the average tenure of a U.S. worker is 4.6 years, we can conduct a one-sample hypothesis test. Let's define the null hypothesis (H₀) and the alternative hypothesis (H₁):

H₀: The average tenure of a U.S. worker is 4.6 years.

H₁: The average tenure of a U.S. worker is not equal to 4.6 years.

To perform this test, we need a sample of worker tenures. We can collect data on the tenure of a representative sample of U.S. workers. Once we have the data, we can use Excel to calculate the necessary statistics and conduct the hypothesis test.

In Excel, we can use the T.TEST function to perform the one-sample t-test. The function takes the sample data, the expected mean (4.6 years), and the type of test (two-tailed in this case). It returns the p-value, which represents the probability of obtaining a sample mean as extreme as the one observed, assuming the null hypothesis is true.

We compare the p-value to a predetermined significance level (e.g., α = 0.05) to determine if we reject or fail to reject the null hypothesis. If the p-value is less than α, we reject the null hypothesis and conclude that the average tenure is significantly different from 4.6 years. Otherwise, if the p-value is greater than α, we fail to reject the null hypothesis and conclude that there is not enough evidence to suggest a significant difference.

After two iterations of the Chebyshev method with an initial approximation of X0 = 0.1, the approximate value of 1/7 is -0.5.

To perform two iterations of the Chebyshev method, we start with the initial approximation Xo = 0.1 and use the formula:

Xn+1 = 2Xn - (7Xn^2 - 1)

Using the initial approximation X0 = 0.1:

X1 = 2 * 0.1 - (7 * 0.1^2 - 1)

  = 0.2 - (0.7 - 1)

  = 0.2 - 0.3

  = -0.1

Using X1 as the new approximation:

X2 = 2 * (-0.1) - (7 * (-0.1)^2 - 1)

  = -0.2 - (0.7 - 1)

  = -0.2 - 0.3

  = -0.5

No, if two entire functions agree on a segment of the real axis, it does not necessarily imply that they agree on the complex plane.

While it is true that two entire functions that agree on a segment of the real axis will have the same Taylor series expansion and hence the same values on the real line, this does not guarantee that they will agree on the entire complex plane. The behavior of complex functions can differ significantly from their behavior on the real line.

Consider, for example, the entire functions [tex]f(z) = e^z[/tex] and [tex]g(z) = e^-^z^\\^2^[/tex]. These functions agree on the real axis,  [tex]e^z[/tex] and [tex]e^-^z^\\^2^[/tex] both reduce to e^x for real values of x. However, on the complex plane, these functions have distinct behaviors. While f(z) is an entire function that grows exponentially in all directions, g(z) has a Gaussian-like shape and decays rapidly as the imaginary part of z increases.

Therefore, agreement on a segment of the real axis does not imply agreement on the entire complex plane, as the complex behavior of functions can be vastly different from their behavior on the real line.

Given, generating function © is non-negative integer-valued random variable where c(x) = E[ x©]. To express E[83] in terms of ♡ and its derivatives let’s find ©(1) = E[©].

Derivative of c(x) isc1(x) = E[© x© -1]

Evaluating c1(1) = E[©1] = E[©] = ©(1)

Similarly, second derivative of c(x) isc2(x) = E[©(© - 1)x© - 2]

Evaluating c2(1) = E[©(© - 1)] = E[©2 - ©]E[©2] - E[©] = ©(2) - ©(1)

We are given 3 = EICS) -Σουφο) + bx®(k)(1)

On average, the number of type B patients seen in the emergency room is N * [(1 - p) / (1 - p + q/2)].

On average, the number of type B patients seen in the emergency room can be determined using conditional expectation properties. The answer is as follows:

The average number of type B patients seen in the emergency room can be calculated by considering the conditional expectation of the number of type B patients given that a patient is not of type A.

Let's denote this average number as E(B|not A).

Since the probability of a patient being type A is p, the probability of a patient not being type A is 1 - p.

Let's denote this probability as q = 1 - p.

The conditional probability of a patient being type B given that they are not type A is the probability of being type B (30-minute requirement) divided by the probability of not being type A (15-minute requirement).

This can be written as P(B|not A) = (1 - p) / (1 - p + q/2), where q/2 represents the probability of a patient being type B.

Using conditional expectation properties, we can calculate the average number of type B patients as E(B|not A) = N * P(B|not A).

Therefore, on average, the number of type B patients seen in the emergency room is N * [(1 - p) / (1 - p + q/2)].

The total surface area of the cylinder is approximately 116.28 cm² (rounded to two decimal places).

To find the surface area of the cylinder, we need to first find the height of the cylinder. We know that the circumference of the base of the cylinder is equal to the length of the square paper, which is 10 cm.

The formula for the circumference of a circle is C = 2πr, where C is the circumference and r is the radius. Since we know that the circumference is 10 cm, we can solve for the radius:

10 = 2πr

r = 5/π

Now that we know the radius, we can find the height of the cylinder. The height is equal to the length of the square paper, which is 10 cm.

So, the surface area of the lateral surface of the cylinder is given by:

Lateral Surface Area = 2πrh

= 2π(5/π)(10)

= 100 cm²

The surface area of each end of the cylinder (i.e., top and bottom) is equal to πr². So, the total surface area of both ends is:

Total End Surface Area = 2πr²

= 2π(5/π)²

= 50/π cm²

Therefore, the total surface area of the cylinder is:

Total Surface Area = Lateral Surface Area + Total End Surface Area

= 100 + (50/π)

≈ 116.28 cm² (rounded to two decimal places)

Evaluating the integrals results to

∫√(x√2x² - 5) dx = [tex]\sqrt{2} (x^{2} \sqrt{2} - 5) ^{1/2}[/tex] + C.

∫x cos(2x) dx = (1/2) x sin(2x) + (1/4) cos(2x) + C

∫ dx / ((x+2)(x+3)) = (1/5) ln|x+3| - (1/5) ln|x+2| + C.

evaluating the given integrals one by one:

(i) ∫√(x√2x² - 5) dx:

∫√(x√2x² - 5) dx = ∫√(x * x√2 - 5) dx = ∫√(x²√2 - 5) dx.

if u = x²√2 - 5.

du/dx = 2x√2,

dx = du / (2x√2)

substituting these values into the integral:

∫√(x²√2 - 5) dx = ∫√u * (du / (2x√2)) = (1 / (2√2)) ∫√u / x du.

factoring out [tex]u^{1/2}[/tex] / x, we get:

(1 / (2√2)) ∫([tex]u^{1/2}[/tex] / x) du

= (1 / (2√2)) ∫[tex]u^{1/2}[/tex] * u⁻¹ du

= (1 / (2√2)) ∫[tex]u^{-1/2}[/tex] du.

Integrating [tex]u^{-1/2}[/tex]

(1 / (2√2)) * (2[tex]u^{1/2}[/tex]) + C = √2[tex]u^{1/2}[/tex] + C,

where C is the constant of integration.

Finally, substitute back u = x²√2 - 5 to get the final result:

∫√(x√2x² - 5) dx = [tex]\sqrt{2} (x^{2} \sqrt{2} - 5) ^{1/2}[/tex] + C.

(ii) ∫x cos(2x) dx:

To evaluate this integral, we can use integration by parts.

if u = x and dv = cos(2x) dx.

du = dx and v = (1/2)sin(2x).

Using the integration by parts formula ∫u dv = uv - ∫v du, we can write:

∫x cos(2x) dx = (1/2)x sin(2x) - (1/2)∫sin(2x) dx.

Integrating sin(2x)

(1/2)x sin(2x) + (1/4)cos(2x) + C,

(iii) ∫dx / ((x+2)(x+3))

To evaluate the integral ∫ dx / ((x+2)(x+3)), we can use partial fraction decomposition.

∫ dx / ((x+2)(x+3)) = ∫ (A/(x+2) + B/(x+3)) dx.

multiplying both sides by (x+2)(x+3)

1 = A(x+3) + B(x+2).

Expanding and equating coefficients

1 = (A + B)x + (3A + 2B).

A + B = 0 and 3A + 2B = 1.

Solving these equations, we find A = -1/5 and B = 1/5.

Substituting the values of A and B back into the integral, we have:

∫ dx / ((x + 2) (x + 3)) = ∫ (-1/5(x + 2) + 1/5(x + 3)) dx,

= (-1/5) ln |x + 2| + (1/5) ln |x + 3| + C,

= (1/5) ln |x + 3| - (1/5) ln |x + 2| + C.
