Answer: we can conclude that the two vectors are parallel because they have the same direction.

Step-by-step explanation:

a) To find the constant k such that the system has no solution, we can use the determinant of the system as a criterion.

So, the system will have no solution if and only if the determinant is equal to zero and the equation is as follows:

| 1 - 3 | 2 | 1 || -1 k | 0 | = 0

Expanding the above determinant, we get:

|-3k| - 0 | = 0

We can see that the determinant is zero for any value of k.

So, there are infinitely many solutions.

b) We are given the system:

x - 3y = 2-x + k

y = 0

Now, we will rewrite the system using vectors as follows:

⇒ r. = r0 + td

Where d = (1, -3) and r0 = (2, 0)

Then, the equation x - 3y = 2 can be written as:

r. = (2, 0) + t(1, -3)

Next, we will substitute the value of k in the system to find the equation of the second line.

We know that the system has no solution for

k = 0.

So, the equation of the second line is:

r. = (0, 0) + s(3, 1)

The mean of the distribution is 0.5, and the standard error of the distribution is 0.0327.

Sampling distribution refers to the probability distribution that results from taking a large number of samples.

It provides information on the probability distribution of the sample's statistics.

If the efficacy of a drug is 0.5, and the sample size n-187, then the proportion of patients cured by the drug is expected to be 0.5.

The mean of the distribution of the proportion of patients cured by the drug is equal to the proportion of patients cured by the drug, which is 0.5.

The standard error of the distribution is the square root of the product of the variance of the proportion of patients cured by the drug, which is 0.25, and the reciprocal of the sample size.

So, the standard error is = √(0.25/187)

= 0.0327 (rounded to four decimal places).

Therefore, the mean of the distribution is 0.5, and the standard error of the distribution is 0.0327.

To solve the Boy or Girl paradox, we need to consider the various possibilities and their probabilities.

a. Mr. Jones has two children. The older child is a girl. We need to find the probability that both children are girls. Let's denote the children as A (older child) and B (younger child). The possible combinations of genders are as follows:

1. Girl-Girl (GG)

2. Girl-Boy (GB)

3. Boy-Girl (BG)

4. Boy-Boy (BB)

We know that the older child is a girl, which eliminates the fourth possibility (BB). Now we are left with three equally likely possibilities: GG, GB, and BG.

Since each possibility is equally likely, the probability of each is 1/3. However, we want to find the probability that both children are girls given that the older child is a girl. Out of the three possibilities, only one satisfies this condition (GG). Therefore, the probability that both children are girls, given that the older child is a girl, is 1/3.

b. Mr. Smith has two children, and we know that at least one of them is a boy. Again, let's denote the children as A (first child) and B (second child). The possible combinations of genders are the same as in the previous case:

1. Girl-Girl (GG)

2. Girl-Boy (GB)

3. Boy-Girl (BG)

4. Boy-Boy (BB)

We are given that at least one of the children is a boy. This means that the only possibility that is eliminated is GG. We are left with three equally likely possibilities: GB, BG, and BB.

Since each possibility is equally likely, the probability of each is 1/3. However, we want to find the probability that both children are boys, given that at least one of them is a boy. Out of the three possibilities, only one satisfies this condition (BB). Therefore, the probability that both children are boys, given that at least one of them is a boy, is 1/3.

In summary:

a. The probability that both children are girls, given that the older child is a girl, is 1/3.

b. The probability that both children are boys, given that at least one of them is a boy, is 1/3.

These results might seem counterintuitive at first glance, but they can be explained by the fact that the gender of one child does not affect the gender of the other child. Each child has an independent probability of being a boy or a girl, and the given information only provides partial knowledge about one child, without influencing the other.

The true relative risk of the experimental medication lies between 1.17 and 3.53 with 95% certainty.

Generate a 95% confidence interval (CI) for the difference in proportions of participants reporting a reduction of symptoms between the experimental and placebo groups. The formula for the 95% confidence interval (CI) for the difference in proportions of participants reporting a reduction of symptoms between the experimental and placebo groups is given by; CI = (p1 - p2) ± 1.96 * √ [(p1 * (1 - p1) / n1) + (p2 * (1 - p2) / n2)
Where;
p1 = the proportion of participants in the experimental group that reported a reduction of symptoms
p2 = the proportion of participants in the placebo group that reported a reduction of symptoms
n1 = the number of participants in the experimental group
n2 = the number of participants in the placebo group
Substitute the values into the formula.
p1 = 38/100 = 0.38
p2 = 21/100 = 0.21
n1 = n2 = 100
CI = (0.38 - 0.21) ± 1.96 * √ [(0.38 * (1 - 0.38) / 100) + (0.21 * (1 - 0.21) / 100)]
CI = 0.17 ± 1.96 * 0.079
CI = 0.17 ± 0.155
CI = (0.015, 0.325). Hence, the 95% confidence interval (CI) for the difference in proportions of participants reporting a reduction of symptoms between the experimental and placebo groups is (0.015, 0.325).

Estimate the relative risk (RR) for reduction in symptoms between groups.
The formula for calculating the relative risk (RR) is given by;
RR = (a / (a + b)) / (c / (c + d))
Where;
a = number of participants who received the experimental medication and reported a reduction in symptoms
b = number of participants who received the experimental medication but did not report a reduction in symptoms
c = number of participants who received the placebo and reported a reduction in symptoms
d = number of participants who received the placebo but did not report a reduction in symptoms
Substitute the values into the formula.
a = 38
b = 62
c = 21
d = 79
RR = (38 / (38 + 62)) / (21 / (21 + 79))
RR = 0.38 / 0.21
RR = 1.81
Hence, the relative risk (RR) for reduction in symptoms between the experimental and placebo groups is 1.81.

Estimate the odds ratio (OR) for reduction in symptoms between groups.
The formula for calculating the odds ratio (OR) is given by;
OR = (a * d) / (b * c)
Substitute the values into the formula.
a = 38
b = 62
c = 21
d = 79
OR = (38 * 79) / (62 * 21)
OR = 1.44

Hence, the odds ratio (OR) for a reduction in symptoms between the experimental and placebo groups is 1.44. Generate a 95% confidence interval (CI) for the relative risk (RR).

The formula for calculating the standard error (SE) of the logarithm of the relative risk is given by;
SE = √ [(1 / a) - (1 / (a + b)) + (1 / c) - (1 / (c + d))]
The formula for calculating the confidence interval (CI) of the relative risk is given by; CI = e^(ln(RR) - 1.96 * SE) to e^(ln(RR) + 1.96 * SE)
Substitute the values into the formulas
SE = √ [(1 / 38) - (1 / (38 + 62)) + (1 / 21) - (1 / (21 + 79))]
SE = 0.283
CI = e^(ln(1.81) - 1.96 * 0.283) to e^(ln(1.81) + 1.96 * 0.283)
CI = 1.17 to 3.53

Hence, the 95% confidence interval (CI) for the relative risk (RR) is (1.17 to 3.53). The clinical trial was conducted to compare the effectiveness of an experimental medication to placebo in reducing the symptoms of asthma. The trial consisted of 200 participants who were randomly assigned to receive either the experimental medication or placebo. The primary outcome of the trial was a self-reported reduction of symptoms. Of the 100 participants who received the experimental medication, 38 reported a reduction in symptoms as compared to 21 participants who received the placebo. The results of the study were analyzed to generate a 95% confidence interval (CI) for the difference in proportions of participants reporting a reduction of symptoms between the experimental and placebo groups. The 95% CI was found to be (0.015, 0.325), which means that the true difference in proportions of participants reporting a reduction of symptoms between the experimental and placebo groups lies between 0.015 and 0.325 with 95% certainty. Hence, the experimental medication is statistically significant in reducing the symptoms of asthma compared to placebo. The relative risk (RR) was estimated to be 1.81, which indicates that the experimental medication is 1.81 times more effective in reducing the symptoms of asthma compared to placebo.

The odds ratio (OR) was estimated to be 1.44, which indicates that the odds of experiencing a reduction in symptoms in the experimental group were 1.44 times higher than the odds in the placebo group. A 95% CI for the relative risk (RR) was also generated, which was found to be (1.17 to 3.53). This means that the true relative risk of the experimental medication lies between 1.17 and 3.53 with 95% certainty. The clinical trial showed that the experimental medication is more effective in reducing the symptoms of asthma compared to the placebo.

The function g(x) = (x² - 1)/2 satisfies f o g = h.

The given problem asks us to find a function g such that the composition of f and g, denoted as f o g, is equal to the function h. The function f(x) = 2x + 5 and h(x) = 2x² + 2x + 3 are given. To find g(x), we substitute f(x) into h(x) and solve for g(x).

By substituting f(x) into h(x), we have:

h(x) = f(g(x)) = 2(g(x)) + 5

Substituting h(x) = 2x² + 2x + 3, we get:

2x² + 2x + 3 = 2(g(x)) + 5

Rearranging the equation, we have:

2(g(x)) = 2x² + 2x - 2

Dividing both sides by 2, we get:

g(x) = (x² - 1)/2

Therefore, the function g(x) = (x² - 1)/2 satisfies f o g = h.

Given the vector p(t) = -3 + 41 + 91² and the set of vectors S = {1 + 4, 1 - t², t²}, we need to express p(t) as a linear combination of the vectors in S.

To do this, we need to find constants a, b, and c such that: p(t) = a(1 + 4) + b(1 - t²) + c(t²)

Expanding the right-hand side and simplifying, we get: p(t) = (a + b) + 4a - bt² + ct²

We can now set up a system of equations by equating the coefficients of the corresponding terms on both sides of the equation:

coefficients of 1:

a + b = 41

coefficients of t²:

c - b = 91²

coefficients of t⁴:

To solve the given differential equation, y" - 16y = 6x + ex, using the Method of Undetermined Coefficients, we first consider the homogeneous solution. The characteristic equation is r^2 - 16 = 0, which gives us the roots r1 = 4 and r2 = -4. Therefore, the homogeneous solution is y_h = c1e^(4x) + c2e^(-4x), where c1 and c2 are constants.

Next, we focus on finding the particular solution for the non-homogeneous term. Since we have a linear term and an exponential term on the right-hand side, we assume a particular solution of the form y_p = Ax + B + Cex.

Differentiating y_p twice, we find y_p" = 0 + 0 + Cex = Cex, and substitute into the original equation:

Cex - 16(Ax + B + Cex) = 6x + ex

Simplifying the equation, we have:

(C - 16C)ex - 16Ax - 16B = 6x + ex

Comparing the coefficients, we find C - 16C = 1, -16A = 6, and -16B = 0.

Solving these equations, we get A = -3/8, B = 0, and C = -1/15.

Therefore, the particular solution is y_p = (-3/8)x - (1/15)ex.

Finally, the general solution is the sum of the homogeneous and particular solutions:

y = y_h + y_p = c1e^(4x) + c2e^(-4x) + (-3/8)x - (1/15)ex.

The eigenvalues and the corresponding eigenvectors of the following matrix Eigenvalue: λ = 53 and Eigenvector: x = [1]

Given a matrix A = [53], to find the eigenvalues and the corresponding eigenvectors.

We'll start by finding the eigenvalues.

Eigenvectors and eigenvalues of a matrix are widely used in Linear Algebra.

A eigenvector of a matrix A is a nonzero vector x such that when A is multiplied by x, it is the same as multiplying a scalar λ (lambda) with x, i.e., Ax = λx.

The scalar λ is called the eigenvalue of the matrix A.

To find the eigenvalues of the matrix A, we start by finding the determinant of A - λI,

where I is the identity matrix of order 1. A - λI = [53 - λ] and det(A - λI) = 53 - λ.

Hence, the eigenvalues of A are λ = 53.

To find the corresponding eigenvectors, we solve the equation (A - λI)x = 0 where x is a non-zero vector. (A - λI) = [53 - λ]  

The equation (A - λI)x = 0 becomes (53 - λ)x = 0 where x is a non-zero vector.

Therefore, x is an eigenvector corresponding to the eigenvalue λ = 53.

Since there are infinitely many solutions to the equation, we can choose any non-zero vector as the eigenvector. For instance, let's choose x = [1].

Therefore, the eigenvalues and the corresponding eigenvectors of A are λ = 53 and x = [1], respectively.

Hence, we can summarize the result as follows:

The probability of success (defective bulb) is 1% or 0.01, and the probability of failure (non-defective bulb) is 99% or 0.99. Plugging in these values into the formula, we have P(X = 3) = (250 choose 3) * 0.01^3 * 0.99^(250-3), where (250 choose 3) represents the combination of choosing 3 bulbs out of 250. Evaluating this expression gives us the desired probability.

We are given three points, P(1, -1, 2), Q(-1, 0, 1), and R(1, -1, 1), and are asked to find the equation of the plane that passes through these points.

To find the equation of the plane, we can use the point-normal form of a plane, which states that a plane can be defined by a point on the plane and the normal vector perpendicular to the plane. To find the normal vector of the plane, we can use the cross product of two vectors that lie on the plane. Let's take two vectors, PQ and PR, where PQ = Q - P and PR = R - P. We can calculate the cross product of PQ and PR to obtain the normal vector.  

PQ = (-1 - 1, 0 - (-1), 1 - 2) = (-2, 1, -1)

PR = (1 - 1, -1 - (-1), 1 - 2) = (0, 0, -1)

Normal vector N = PQ x PR = (-2, 1, -1) x (0, 0, -1) = (1, -2, -2)

Now that we have the normal vector, we can substitute the coordinates of one of the points, let's say P(1, -1, 2), and the normal vector (A, B, C) into the point-normal form equation: A(x - x1) + B(y - y1) + C(z - z1) = 0, where (x1, y1, z1) is the point on the plane.

Substituting the values, we have A(1 - 1) + B(-1 - (-1)) + C(2 - 2) = 0, which simplifies to A(0) + B(0) + C(0) = 0. This implies that A, B, and C are all zero.

Therefore, the equation of the plane passing through the points P(1, -1, 2), Q(-1, 0, 1), and R(1, -1, 1) is 0x + 0y + 0z = D, or simply 0 = D.

The eigenvalues of A are 0 and 0 (multiplicity 2), and the eigenvectors corresponding to the eigenvalue[tex]λ=0[/tex] are all vectors in R2.

The matrix given is [tex]A=0 0 0[/tex]

In order to find all the eigenvalues of A, we first have to solve the following equation det(A-λI)=0 where I is the identity matrix of order 2 and λ is the eigenvalue of A.

Substituting the value of A, we get det(0 0 0 λ) = 0λ multiplied by the 2×2 matrix of zeros will result in a zero determinant.

Therefore, the above equation has a root λ=0 of multiplicity 2.

Thus, the eigenvalue of A is 0.

Now we have to find the eigenvectors corresponding to the eigenvalue[tex]λ=0.[/tex]

Let [tex]x=[x1, x2]T[/tex] be an eigenvector of A corresponding to the eigenvalue λ=0.

Thus, we have Ax = λx which gives

[tex]0*x = A*x \\= [0, 0]T.[/tex]

Therefore, we get the following homogeneous system of equations:0x1 + 0x2 = 00x1 + 0x2 = 0

This system has only one free variable (either x1 or x2 can be chosen as free) and the solution is given by the set of all vectors of the form [tex][x1, x2]T = x1 [1, 0]T + x2 [0, 1]T[/tex] where x1 and x2 are any arbitrary scalars.

Thus, the eigenspace corresponding to the eigenvalue λ=0 is the span of the vectors [tex][1, 0]T and [0, 1]T.[/tex]

Hence, the eigenspace corresponding to the eigenvalue λ=0 is R2 itself, that is, has eigenspace span[tex]{[1, 0]T, [0, 1]T}.[/tex]

Therefore, the eigenvalues of A are 0 and 0 (multiplicity 2), and the eigenvectors corresponding to the eigenvalue λ=0 are all vectors in R2.

The limit as x approaches infinity of the given expression is infinity.

To find the limit as x approaches infinity of the given expression, we can analyze the highest power terms in the numerator and denominator, as they dominate the behavior of the function as x becomes large.

In the numerator, the highest power term is 3x³, and in the denominator, the highest power term is 4x². Dividing both the numerator and denominator by x², we get:

lim(x→∞) (3x³ - 6x - 2) / (4x² + x)

= lim(x→∞) (3x - 6/x² - 2/x²) / (4 + 1/x)

As x approaches infinity, the terms involving 1/x² and 1/x become negligible compared to the dominant terms of 3x and 4. Thus, the limit can be simplified to:

lim(x→∞) (3x - 0 - 0) / (4 + 0)

= lim(x→∞) (3x) / 4

Since x is approaching infinity, the numerator also approaches infinity. Hence, the limit is:

lim(x→∞) (3x) / 4 = ∞

Therefore, the limit as x approaches infinity of the given expression is infinity.

(a) To test the difference in mean weight at birth between urban and rural women, a two-sample t-test can be used. The significance level of 5% implies that we are willing to accept a 5% chance of incorrectly rejecting the null hypothesis.

The t-test compares the means of the two samples, considering their respective sample sizes and standard deviations. By calculating the test statistic and comparing it to the critical value from the t-distribution with appropriate degrees of freedom, we can determine whether the observed difference is statistically significant.

(b) To test whether the observed mean weight at birth of children from sample urban mothers is greater than the predicted weight of 3.5000 kg, a one-sample t-test can be conducted. The null hypothesis (H₀) assumes that the mean weight is equal to or less than 3.5000 kg, while the alternative hypothesis (H₁) suggests that the mean weight is greater.

Similar to the previous test, the t-test calculates the test statistic using the sample mean, standard deviation, and sample size. By comparing the test statistic to the critical value from the t-distribution with appropriate degrees of freedom, we can determine whether the observed mean weight is significantly greater than the predicted weight.

The change in y (Ay) when x = 4 and Ax = 0.4 can be found by evaluating the derivative of y = 3√x and substituting the given values. The differential dy when x = 4 and dx = 0.4 can be calculated using the differential notation.

To find Ay, we first differentiate y = 3√x with respect to x. Using the power rule, we have:

dy/dx = d/dx (3√x) = (1/2) * 3 * x^(-1/2) = 3/(2√x)

Substituting x = 4 into the derivative expression, we get:

dy/dx = 3/(2√4) = 3/4

To find Ay, we multiply the derivative by the change in x:

Ay = (dy/dx) * Ax = (3/4) * 0.4 = 0.3

On the other hand, the differential notation allows us to express the change in y (dy) in terms of the change in x (dx) using the formula dy = (dy/dx) * dx. Substituting the given values, we have:

dy = (dy/dx) * dx = (3/(2√x)) * 0.4 = (3/(2√4)) * 0.4 = 0.3

Therefore, both the change in y (Ay) and the differential dy when x = 4 and dx = 0.4 are equal to 0.3.

The truth value of the given statements are:

Let's analyze each statement:

|P(A × B)| = 64

The set A × B represents the Cartesian product of sets A and B. In this case, A × B = {(a, b), (a, {c}), (b, b), (b, {c}), (c, b), (c, {c})}. Therefore, P(A × B) is the power set of A × B, which includes all possible subsets of A × B.

The cardinality of P(A × B) is 2^(|A × B|), which in this case is 2^6 = 64. Hence, the statement is true.

{b, c} = P(A)

The power set of A, denoted as P(A), is {{}, {a}, {b}, {c}, {a, b}, {a, c}, {b, c}, {a, b, c}}.

Therefore, the statement {b, c} = P(A) is false because P(A) contains more elements than just {b, c}.

CEA - B

The expression CEA represents the complement of set A, which includes all elements not in A. B represents the set {b, {c}}.

Subtracting B from CEA means removing the elements of B from the complement of A.

Since {b, {c}} is not an element in the complement of A, the result of the subtraction CEA - B is still the complement of A.

BCA

The expression BCA represents the intersection of sets B, C, and A. However, the set C is not given in the problem. Therefore, we cannot determine the truth value of this statement without the knowledge of the set C.

{{{c}}} ≤ P(B)

The expression P(B) represents the power set of set B, which is {{}, {b}, {{c}}, {b, {{c}}}}.

The set {{{c}}} represents a set containing the set {c}. Therefore, the union of the set {{{c}}} with any other set will result in the set itself.

Since the power set P(B) already contains the set {{c}}, which is the same as {{{c}}}, the union of the two sets does not change the power set P(B).

Therefore, the statement + {{{c}}} ≤ P(B) is true.

Therefore, the derivative of the function at point P₀ in the direction of A is -48/√17.

The gradient of the function f(x, y) = 2xy + 3y² is given by ∇f = (∂f/∂x, ∂f/∂y), where ∂f/∂x represents the partial derivative of f with respect to x, and ∂f/∂y represents the partial derivative of f with respect to y.

Taking the partial derivative of f with respect to x, we get ∂f/∂x = 2y. Similarly, the partial derivative of f with respect to y is ∂f/∂y = 2x + 6y.

At point P₀(4, -7), the directional derivative in the direction of vector A = 8i - 2j can be computed as the dot product between the gradient and the unit vector in the direction of A.

First, we normalize vector A to obtain the unit vector by dividing A by its magnitude. The magnitude of A is √((8)^2 + (-2)^2) = √(64 + 4) = √68 = 2√17. Therefore, the unit vector in the direction of A is (1/(2√17))(8i - 2j) = (4/√17)i - (1/√17)j.

Next, we calculate the dot product of the gradient ∇f and the unit vector in the direction of A: ∇f · A = (∂f/∂x, ∂f/∂y) · [(4/√17)i - (1/√17)j] = (2y, 2x + 6y) · [(4/√17)i - (1/√17)j] = (2(-7), 2(4) + 6(-7)) · [(4/√17)i - (1/√17)j] = (-14, -8) · [(4/√17)i - (1/√17)j] = (-14 * (4/√17)) + (-8 * (-1/√17)) = (-56/√17) + (8/√17) = (-48/√17).

Therefore, the derivative of the function at point P₀ in the direction of A is -48/√17.

If Σax" is conditionally convergent series for x=2, n=0. The correct option is c.

A conditionally convergent series is one in which the series converges, but not absolutely. In this case, Σax^n is conditionally convergent for x = 2, n = 0.

Statement I states that Σa is conditionally convergent. This statement is true because when n = 0, the series becomes Σa, which is the same as the original series Σax^n without the x^n term. Since the original series is conditionally convergent, removing the x^n term does not change its convergence behavior, so Σa is also conditionally convergent.

Statement II states that Σ2^n is absolutely convergent. This statement is false because the series Σ2^n is a geometric series with a common ratio of 2. Geometric series are absolutely convergent if the absolute value of the common ratio is less than 1. In this case, the absolute value of the common ratio is 2, which is greater than 1, so the series Σ2^n is not absolutely convergent.

Statement III states that Σa*(-3)^n is divergent. This statement is not directly related to the original series Σax^n, so it cannot be determined based on the given information. The convergence or divergence of Σa*(-3)^n would depend on the specific values of the series coefficients a.

The partial fraction decomposition of 1[tex]0x + 2 (x - 1)(x^2 + x + 1)[/tex] is [tex]2x^3 - x^2 + 10x / x - 1 + 2x + 2 / x^2 + x + 1[/tex].

We have the expression as,[tex]10x + 2 (x - 1)(x^2 + x + 1)[/tex].

Let's begin the process of finding the partial fraction decomposition for the same.

We have[tex]:10x + 2 (x - 1)(x^2 + x + 1) = Ax + Bx^2 + Cx + D / x - 1 + Ex + F / x^2 + x + 1[/tex]

Multiplying both sides by the denominator gives[tex]:10x + 2 (x - 1)(x^2 + x + 1)[/tex]

=[tex](Ax + Bx^2 + Cx + D) (x^2 + x + 1) + (Ex + F) (x - 1)[/tex]

Expanding the right side gives:[tex]10x + 2 (x^3 + x^2 + x - x^2 - x - 1)[/tex]

= [tex]Ax + Bx^4 + Cx^2 + Dx^2 + x + D + Ex^2 - Ex + Fx - F[/tex]

Collecting like terms gives:[tex]10x + 2x^3 + 2x^2 - 2x - 2[/tex]

= [tex](Bx⁴) + (Ax³) + (C + D)x² + (E - F)x + (D - F)[/tex]

We compare the coefficients of the terms on both sides:[tex]10x + 2x³ + 2x² - 2x - 2[/tex]

= [tex](Bx^4) + (Ax^3) + (C + D)x^2 + (E - F)x + (D - F)[/tex]

By equating coefficients of [tex]x^4[/tex], we get B = 0. Equating coefficients of[tex]x^3[/tex], we get A = 2.

Equating coefficients of [tex]x^2[/tex], we get C + D = 0.

Equating coefficients of x, we get E - F = 10.

Equating the constant terms, we get D - F - 2

= -2

or D - F = 0

or D = F.

By substituting the values of B, A, C, and D, we get:[tex]10x + 2 (x - 1)(x^2 + x + 1)[/tex]

=[tex]2x^3 - x^2 + 10x / x - 1 + 2x + 2 / x^2 + x + 1[/tex]

Therefore, the partial fraction decomposition of [tex]10x + 2 (x - 1)(x^2 + x + 1)[/tex] is [tex]2x^3 - x^2 + 10x / x - 1 + 2x + 2 / x^2 + x + 1[/tex].
