f1(y,w) = ry - 2w = 0

f2(y,w) = y - 2w² + 2 = 0

f3(y,w) = y + 5 - 2² = 0

∂f3/∂y = 1

∂f3/∂w = 0

Putting the given values in above equation:

i)a) The function u(x,y) is harmonic.  ; b)  f(z) = 4x^4 + 8x³i + 4y^4 - 12xy²+ 8y³i ; ii) The result is: Sc (y + x - 4ix)dz = 5i + (y + x - 4 - 4i) (1 + i).

Let's solve the given problem step by step below.

i) a) To show that a function is harmonic, we need to prove that it satisfies the Laplace's equation.

Thus, we can write u(x,y) = -8x3y + 8xy3 in terms of x and y as follows:

u(x,y) = -8x^3y + 8xy^3

∴ ∂u/∂x = -24x^2y + 8y^3  ----(i)

∴ ∂²u/∂x² = -48xy ----(ii)

Similarly, we can find the partial derivatives with respect to y:

∴ ∂u/∂y = -8x^3 + 24xy²  ----(iii)

∴ ∂²u/∂y² = 48xy ----(iv)

Therefore, by adding (ii) and (iv), we get

:∂²u/∂x² + ∂²u/∂y² = 0

So, the function u(x,y) is harmonic.

b) We know that if a function u(x,y) is harmonic, then the conjugate harmonic function y(x,y) can be found as:

y(x,y) = ∫∂u/∂x dy - ∫∂u/∂y dx + c

where c is a constant of integration.

Here,

∂u/∂x = -24x^2y + 8y^3

∂u/∂y = -8x^3 + 24xy²

∴ ∫∂u/∂x dy = -12x²y² + 4y^4 + d1(y)

∴ ∫∂u/∂y dx = -4x^4 + 12x²y² + d2(x)

where d1(y) and d2(x) are constants of integration.

To get the value of c, we can equate both the integrals:

d1(y) = -4x^4 + 12x²y² + c

Therefore,

y(x,y) = -12x²y² + 4y^4 - 4x^4 + 12x²y² + c

= 4y^4 - 4x^4 + c

Now, we can find f(z) using the Cauchy-Riemann equations:

∴ u_x = -24x^2y + 8y^3

= v_y

∴ u_y = -8x^3 + 24xy²

= -v_x

Thus,

f'(z) = u_x + iv_x

= -24x^2y + 8y^3 - i(8x^3 - 24xy²)

= (8y^3 + 24xy²) - i(8x^3 + 24xy²)

Therefore,

f(z) = ∫f'(z) dz

= ∫[(8y^3 + 24xy²) - i(8x^3 + 24xy²)] dz

= 4x^4 + 8x³i + 4y^4 + 8y³i - 12xy²i²

= 4x^4 + 8x³i + 4y^4 - 12xy²+ 8y³i

Let's evaluate Sc (y + x - 4ix)dz where c is represented by:

C: The straight line from Z = 0 to Z = 1+i C

z: Along the imaginary axis from Z = 0 to Z = i.

Given,

Sc (y + x - 4ix)dz

= [(y + x - 4ix) (i)] (i - 0) + [(y + x - 4ix) (1 + i)] (0 - i)    

= 5i + (y + x) (1 + i) - 4i (1 + i)    

= 5i + (y + x - 4 - 4i) (1 + i)

Thus, the result is:

Sc (y + x - 4ix)dz

= 5i + (y + x - 4 - 4i) (1 + i).

a) The probability that a random lobster weighs less than 17 oz can be found by calculating the cumulative probability using the normal distribution with the given mean and standard deviation.

b) The probability that the average weight of 70 randomly caught lobsters is within 0.1 oz of the mean weight can be calculated using the sampling distribution of the sample mean, which follows a normal distribution with the same mean as the population and a standard deviation equal to the population standard deviation divided by the square root of the sample size.

c) To find the weight at which a lobster would be in the top 0.1% of lobsters, we need to calculate the z-score corresponding to the desired percentile and then use the z-score formula to find the corresponding weight.

The radius of convergence for the series is infinite (converges for all values of x), and the correct answer choice is "D. 0".

To find the radius of convergence for the power series ∑_(n=0)^(∞) (-1)^n π^(2n) / (2^(2n+1) (2n)!), we can use the ratio test. The ratio test states that if the limit of the absolute value of the ratio of consecutive terms is less than 1, then the series converges. If it is greater than 1, the series diverges.

Let's apply the ratio test to the given series:

a_n = (-1)^n π^(2n) / (2^(2n+1) (2n)!)

To compute the ratio of consecutive terms, we divide the (n+1)-th term by the n-th term:

|r_n| = |[(-1)^(n+1) π^(2(n+1)) / (2^(2(n+1)+1) (2(n+1))!)] / [(-1)^n π^(2n) / (2^(2n+1) (2n)!)]|

     = |(-1)^(n+1) π^(2(n+1)) / (2^(2(n+1)+1) (2(n+1)))! * (2^(2n+1) (2n)!) / (-1)^n π^(2n)|

     = |(-1)^n+1 π^2 / (2^2 * (2n+1)(2n+2))|

Next, we take the limit as n approaches infinity:

lim(n→∞) |(-1)^n+1 π^2 / (2^2 * (2n+1)(2n+2))|

Since the absolute value of (-1)^(n+1) is always 1, we can ignore it. Also, π^2 and 2^2 are constant values. Therefore, we are left with:

lim(n→∞) |1 / ((2n+1)(2n+2))|

The above limit is equal to 0, which is less than 1.

Hence, the radius of convergence for the series is infinite (converges for all values of x), and the correct answer choice is "D. 0".

we need to compute the Fourier coefficients. The general form of the Fourier series for a function f(x) defined on the interval [-π, π] is given by:

f(x) = ao/2 + ∑[n=1 to ∞] (ancos(nx) + bnsin(nx))

where ao, an, and bn are the Fourier coefficients.

To find the coefficients, we can use the formulas:

ao = (1/π) ×∫[-π to π] f(x) dx

an = (1/π)× ∫[-π to π] f(x)×cos(nx) dx

bn = (1/π)×∫[-π to π] f(x)×sin(nx) dx

Let's compute the coefficients for the given function f(x) = eˣ:

Computing ao:

ao = (1/π)×∫[-π to π] eˣ dx

= (1/π) ×[eˣ]_[-π to π]

= (1/π)×([tex]e^{\pi }[/tex] - [tex]e^{-\pi }[/tex])

= (1/π)× ([tex]e^{\pi }[/tex] - [tex]e^{\pi }[/tex])

Computing an:

an = (1/π) ×∫[-π to π] eˣ× cos(nx) dx

= (1/π)× ∫[-π to π] eˣ×cos(nx) dx

= (1/π) ×[(e^x ×sin(nx))/n][-π to π] - (1/πn)×∫[-π to π] eˣ×sin(nx) dx

The second term on the right-hand side is zero because the integral of eˣ  ×cos(nx) over a full period is zero for any positive integer n. So, we have:

an = (1/π)× [([tex]e^{\pi }[/tex]× sin(nπ))/n - [tex]e^{-\pi }[/tex] ×sin(-nπ))/n]

= (1/π) ×[([tex]e^{\pi }[/tex] ×0)/n - [tex]e^{-\pi }[/tex]× 0)/n]

Computing bn:

bn = (1/π)×∫[-π to π] eˣ×sin(nx) dx

= (1/π)× [- (eˣ×cos(nx))/n][-π to π] - (1/πn)×∫[-π to π] eˣ ×cos(nx) dx

= (1/π)× [- ([tex]e^{\pi }[/tex]×cos(nπ))/n + ([tex]e^{-\pi }[/tex]×cos(-nπ))/n] - (1/πn)×[(eˣ×sin(nx))/n][-π to π] - (1/πn²)×∫[-π to π] eˣ×sin(nx) dx

Again, the second term on the right-hand side is zero, so we have:

bn = (1/π)×[- ([tex]e^{\pi }[/tex]×cos(nπ))/n + ([tex]e^{-\pi }[/tex]×cos(-nπ))/n]

= (1/π)×[- ([tex]e^{\pi }[/tex]×cos(nπ))/n + ([tex]e^{-\pi }[/tex]×cos(nπ))/n]

= (1/π)× [(-1)ⁿ×([tex]e^{\pi }[/tex] - [tex]e^{-\pi }[/tex])/n]

Now, let's find the first five terms (a0, a1, a2, b1, b2) of the Fourier series:

a0 = 0 (as computed above)

a1 = 0

a2 = 0

b1 = (1/π) ×[(-1)¹ ×([tex]e^{\pi }[/tex] - [tex]e^{-\pi }[/tex])/1]

The slope of the tangent to the curve f(x) = x² - 1 at the point P(-2, -9) is -4.

The equation, in slope-intercept form, of the line tangent to the curve y=x²-4 at x=5 is y = 10x - 29.

To find the slope of the tangent to the curve f(x) = x² - 1 at the point P(-2, -9), we'll use the definition of the derivative:

m = lim(h→0) [f(x + h) - f(x)] / h

Let's calculate it step by step:

Substitute the values of f(x + h) and f(x) into the formula:

m = lim(h→0) [(x + h)² - 1 - (x² - 1)] / h

Simplify the expression inside the limit:

m = lim(h→0) [(x² + 2xh + h² - 1 - x² + 1)] / h

= lim(h→0) [2xh + h²] / h

Cancel out the common factor of h:

m = lim(h→0) [h(2x + h)] / h

Simplify further:

m = lim(h→0) (2x + h)

= 2x + 0

= 2x

Therefore, the slope of the tangent to the curve f(x) = x² - 1 at the point P(-2, -9) is 2x. Substituting x = -2, we find that the slope is -4.

For the function f(x) = sec(x), we can find its derivative f'(x) using the chain rule. The derivative of sec(x) is sec(x)tan(x). Therefore, f'(x) = sec(x)tan(x).

For the function f(x) = (3 - 2x)^(-1), we'll find its derivative using the power rule and chain rule.

Let u = 3 - 2x, then f(x) = u^(-1). Applying the power rule and chain rule, we have:

f'(x) = -1 * (u^(-2)) * u'

= -1 * (3 - 2x)^(-2) * (-2)

= 2(3 - 2x)^(-2)

Therefore, f'(x) = 2(3 - 2x)^(-2).

To find the equation of the line tangent to the curve y = x² - 4 at x = 5, we need to find the slope of the tangent at that point and use the point-slope form of the equation of a line.

Find the derivative of y = x² - 4:

y' = 2x

Substitute x = 5 into the derivative:

m = 2(5)

= 10

The slope of the tangent at x = 5 is 10.

Plug the point (5, f(5)) = (5, 5² - 4) = (5, 21) and the slope into the point-slope form:

y - y₁ = m(x - x₁)

y - 21 = 10(x - 5)

Simplify the equation:

y - 21 = 10x - 50

y = 10x - 29

The equation of the line tangent to the curve y = x² - 4 at x = 5, in slope-intercept form, is y = 10x - 29.

To evaluate the expression ∫x f(x) f''(x) dx, we need the information about f'(x) and f''(x). Given that f'(1) = -1, f'(5) = 3, f''(1) = 4, and f''(5) = 7, we can compute the integral using the Fundamental Theorem of Calculus.

The Fundamental Theorem of Calculus states that if F(x) is an antiderivative of f(x), then ∫a to b f(x) dx = F(b) - F(a). In this case, we have the function f(x) and its derivatives f'(x) and f''(x) evaluated at specific points.

Since we don't have the function explicitly, we can use the given information to find the antiderivative F(x) of f(x). Integrating f''(x) once will give us f'(x), and integrating f'(x) will give us f(x).

Using the given values, we can integrate f''(x) to obtain f'(x). Integrating f'(x) will give us f(x). Then, we substitute the values of x into f(x) to evaluate it. Finally, we multiply the resulting values of x, f(x), and f''(x) and compute the integral ∫x f(x) f''(x) dx.

a. The probability that a survey respondent will say she or he is not okay with this practice is 0.7775.

b. The probability that a respondent is 30–49 years old and will say she or he is okay with this practice is 0.3979.

c. The probability that a respondent is 50+ years old given that she or he is not okay with this practice is 0.2862.

a. To find the probability that a survey respondent will say she or he is not okay with this practice, we need to add the "Not Okay" responses for all age groups together.

Probability of not being okay with the practice = Probability of being not okay for 18-29 year-olds + Probability of being not okay for 30-49 year-olds + Probability of being not okay for 50+ year-olds.

Probability of not being okay with the practice = 0.1488 + 0.2276 + 0.4011 = 0.7775

b. To find the probability that a respondent is 30–49 years old and will say she or he is okay with this practice, we need to use the following formula:

Probability of being okay with the practice, given a respondent is 30-49 years old = Probability of being okay for 30-49 year-olds / Probability of being in the 30-49-year-old age group.

Probability of being okay with the practice, given a respondent is 30-49 years old = 0.0904 / (0.2276) = 0.3979

c. To find the probability that a respondent is 50+ years old given that she or he is not okay with this practice, we need to use Bayes' theorem:

Probability of being 50+ years old given a respondent is not okay with the practice = Probability of being not okay with the practice, given a respondent is 50+ years old × Probability of being 50+ years old / Probability of being not okay with the practice

Probability of being 50+ years old given a respondent is not okay with the practice = 0.4011 × (0.4011 + 0.0720) / 0.7775 = 0.2862

To prove that every planar graph can be colored with 6 (or less) colors, we will use a proof by induction on the number of vertices in the graph.

Thus, it can be stated as "If G has no vertex of degree ≤ 5, then G is not a connected planar graph."

First, let's establish the base case for the smallest planar graph, which consists of three vertices.

This graph is known as the triangle. It is evident that we can color each vertex with a different color, requiring only three colors.

Now, assume that for any planar graph with k vertices, where k ≥ 3, we can color it with 6 (or less) colors.

We will prove that this holds for a planar graph with k+1 vertices.

Consider a planar graph G with k+1 vertices.

We remove one vertex from G, resulting in a subgraph H with k vertices.

By our induction hypothesis, we can color H with 6 (or less) colors.

Now, we reintroduce the removed vertex back into G.

This vertex is connected to at most five other vertices in G, as it is a planar graph and follows the property that the sum of degrees of all vertices is at most 2 times the number of edges.

Hence, this vertex has at most degree 5.

Since H was colored with 6 (or less) colors, we have at least one color that is not used among the neighbors of the reintroduced vertex.

We can assign this unused color to the reintroduced vertex, resulting in a valid coloring of G.

By induction, we have shown that every planar graph with any number of vertices can be colored with 6 (or less) colors.

Regarding the contrapositive of the implication "If G is a connected planar graph, then G has at least one vertex of degree ≤ 5,"

it can be stated as "If G has no vertex of degree ≤ 5, then G is not a connected planar graph."

(a) The F table is incomplete as it does not give the values for the Mean Squares (MS) and the degrees of freedom (df) for both within and between groups. These are essential parameters for making conclusions and carrying out further tests.

The degrees of freedom can be determined using the formula df = n - 1, where n is the number of observations for each group. Using this formula, the degrees of freedom for the within-groups error is: 100 - 5 = 95 and the between-groups is: 5 - 1 = 4.

To calculate the Mean Squares, we divide the Sum of Squares (SS) by the respective degrees of freedom. The MS for within groups error is therefore: 30.86/95 = 0.325 and for between groups: 3148.61/4 = 787.15.

(b) The F value at a significance level of .01 for this one-way between-subjects ANOVA can be determined by referring to an F distribution table or calculator with 4 and 95 degrees of freedom. At a significance level of .01, the F value is 3.86.
(c) To determine whether to reject or retain the null hypothesis, we compare the obtained F value to the critical F value. If the obtained F value is greater than the critical value, we reject the null hypothesis. Otherwise, we retain it. The critical F value for this ANOVA test with 4 and 95 degrees of freedom at a significance level of .01 is 3.86. Since the obtained F value is 101.92, which is much greater than the critical value, we reject the null hypothesis.

a) the percentage of pages that have no errors is 78.65%.

b) the probability that a page without errors was published by the company B is approximately 37.75%.

a) Determine the % of pages that has no errors

The average amount of errors per page made by A is 0.2, which means that the parameter λ of Poisson distribution is also 0.2.

The average amount of errors per page made by B is 0.3, which means that the parameter λ of Poisson distribution is also 0.3. It is given that the company A is responsible for publishing 60% of the journal, while the company B is responsible for publishing the remaining 40%.

The probability of having 0 errors on a page is given by the Poisson distribution with the appropriate parameter λ as follows:

P(X = 0) = e^(-λ) * λ^0 / 0!

Thus, the probability of a page with no errors published by A is P(A) = e^(-0.2) * 0.2^0 / 0! ≈ 0.8187, while the probability of a page with no errors published by B is P(B) = e^(-0.3) * 0.3^0 / 0! ≈ 0.7408.

The overall probability of a page with no errors is the weighted average of the probabilities above, taking into account the proportion of the pages published by each company:

P(no errors) = 0.6 * P(A) + 0.4 * P(B) ≈ 0.7865

b) Considering a page without errors, determine the probability that it was published by the company B

The probability of a page with no errors published by B is P(B|no errors) = P(B and no errors) / P(no errors) = P(no errors|B) * P(B) / P(no errors)

where P(no errors|B) = e^(-0.3) * 0.3^0 / 0! ≈ 0.7408 is the probability of no errors given that the page was published by B.

Substituting the values:

P(B|no errors) = 0.7408 * 0.4 / 0.7865 ≈ 0.3775

The given problem states that the length (l), width (w), and area (A) of a rectangle are differentiable functions of t. We are asked to write an equation relating l, w, and t when A = 18 and w = 13 when t = 1.

Let's denote the length, width, and area as l(t), w(t), and A(t), respectively. We need to find an equation that relates these variables. We know that the area of a rectangle is given by A = lw. To express A in terms of t, we substitute l(t) and w(t) into the equation: A(t) = l(t) * w(t).

Since we are given specific values for A and w when t = 1, we can substitute those values into the equation. When A = 18 and w = 13 at t = 1, the equation becomes 18 = l(1) * 13. This equation relates the length l(1) to the given values of A and w.

In summary, the equation that relates the length l(t) to the area A(t) and width w(t) is A(t) = l(t) * w(t). When A = 18 and w = 13 at t = 1, the equation becomes 18 = l(1) * 13, expressing the relationship between the length and the given values.

For the distribution described below, the following are the answers:(a) How many modes are expected for the distribution?

Answer: The distribution is probably unimodal.Explanation:In general, there is only one peak for a unimodal distribution. In a bimodal distribution, there are two peaks, whereas in a trimodal distribution, there are three peaks. In this situation, since the data is about the ages of patients being treated for dementia and ages would generally have one peak, the distribution is probably unimodal.

Therefore, the expected number of modes for this distribution is 1.

(b) Is the distribution expected to be symmetric, left-skewed, or right-skewed?

Answer: The distribution is probably left-skewed.

Explanation:In general, symmetric distributions have data that are evenly distributed around the mean, while skewed distributions have data that are unevenly distributed around the mean. A distribution is classified as left-skewed if the tail to the left of the peak is longer than the tail to the right of the peak.

Since dementia is typically found in elderly people, who have a long lifespan and an extended right-hand tail, the distribution of ages of people being treated for dementia is expected to be left-skewed. Therefore, the distribution is probably left-skewed.

The inverse Laplace transform of F(s) = (3s - 5) / (s² + 4s - 21) is f(t) = (1/4)e^(-2t) - (3/4)e^(7t), obtained by partial fraction decomposition and applying known Laplace transform pairs.



To find the inverse Laplace transform of F(s), we can use partial fraction decomposition and the known Laplace transform pairs. First, we factorize the denominator of F(s) to obtain (s + 7)(s - 3).

Next, we express F(s) as a sum of two fractions with unknown coefficients: F(s) = A/(s + 7) + B/(s - 3). Multiplying both sides by (s + 7)(s - 3) and equating the numerators, we get 3s - 5 = A(s - 3) + B(s + 7).By substituting s = 3 and s = -7 into the equation above, we find A = 3/4 and B = -1/4. Thus, F(s) can be rewritten as F(s) = (3/4)/(s + 7) - (1/4)/(s - 3).

Now we can use the known Laplace transform pairs to determine the inverse Laplace transform of F(s). Applying the inverse Laplace transform to each term, we obtain f(t) = (3/4)e^(-7t) - (1/4)e^(3t). Simplifying further, f(t) = (1/4)e^(-2t) - (3/4)e^(7t). Therefore, the inverse Laplace transform of F(s) is f(t) = (1/4)e^(-2t) - (3/4)e^(7t).

The solution to the given 0-1 integer programming model problem by implicit enumeration is x1 = 1, x2 = 1, x3 = 0, x4 = 1, x5 = 0, x6 = 0, x7 = 0, x8 = 1, x9 = 1, with the objective function value of 16.

The given 0-1 integer programming model problem seeks to maximize the objective function 4x1 + 5x2 + x3 + 3x4 + 2x5 + 4x6 + 3x7 + 2x8 + 3x9, subject to a set of constraints. The solution obtained through implicit enumeration reveals that x1, x2, x4, x8, and x9 should be set to 1, while x3, x5, x6, and x7 should be set to 0. This configuration yields an optimal objective function value of 16.

To arrive at this solution, the constraints are analyzed and evaluated systematically. The first constraint states that 3x2 + x4 + x5 ≥ 3x1 + x2, which implies that x1 = 1 and x2 = 1 to maximize the right-hand side of the inequality. The second constraint, x2 + x4 - x5 - x6 ≤ -1, dictates that x2 = 1, x4 = 1, x5 = 0, and x6 = 0 to achieve the maximum value. The third constraint, x2 + 2x6 + 3x7 + x8 + 2x9 ≥ 4, requires x2 = 1, x6 = 0, x7 = 0, x8 = 1, and x9 = 1 to satisfy the condition. Lastly, the fourth constraint, -x3 + 2x5 + x6 + 2x7 - 2x8 + x9 ≤ 5, can be satisfied by setting x3 = 0, x5 = 0, x6 = 0, x7 = 0, x8 = 1, and x9 = 1.

The rate of change of p with respect to q, when q = 2 and f = 6, is -0.375.

To find the rate of change of p with respect to q, we need to differentiate the lens equation with respect to q. Let's start by rearranging the equation:

1/f = 1/p + 1/q

To differentiate both sides, we use the reciprocal rule:

-1/f^2 * df/dq = -1/p^2 * dp/dq - 1/q^2

Since we are interested in finding the rate of change of p with respect to q (dp/dq), we rearrange the equation to solve for it:

dp/dq = (-1/p^2 * -1/q^2) * (-1/f^2 * df/dq)

Substituting the given values f = 6 and q = 2:

dp/dq = (-1/p^2 * -1/2^2) * (-1/6^2 * df/dq)

= (-1/p^2 * -1/4) * (-1/36 * df/dq)

= (1/p^2 * 1/4) * (1/36 * df/dq)

= df/dq * 1/(4p^2 * 36)

Since we are only interested in the rate of change when q = 2 and f = 6, we substitute these values:

dp/dq = df/dq * 1/(4 * 6^2 * 36)

= df/dq * 1/(4 * 36 * 36)

= df/dq * 1/5184

Therefore, when q = 2 and f = 6, the rate of change of p with respect to q is -0.375 (since dp/dq is negative).

the final solution of the given PDE is given by u(x,t) = e^(-9t) erf((x / (2√3t))), where t > 0.

Given PDE: ut - 9Uxx = 0, and the initial condition u(x,0) = e^5x.

The solution of the given partial differential equation (PDE) can be determined as follows:

Let us assume that the solution u(x, t) is in the form of: u(x,t) = X(x) T(t)

Putting the value of u(x,t) in the given PDE, we get:

X(x) T'(t) - 9X''(x) T(t) = 0

Dividing throughout by X(x) T(t), we get:

T'(t)/T(t) = 9X''(x)/X(x) = λ

Let us solve T'(t)/T(t) = λ

For λ > 0, T(t) = c1e^(λt)

For λ = 0, T(t) = c1

For λ < 0, T(t) = c1e^(λt)

Using u(x,t) = X(x) T(t),

we get: X(x) T'(t) - 9X''(x) T(t)

= 0X(x) λ T(t) - 9X''(x) T(t)

= 0X''(x) - (λ/9) X(x)

= 0

The characteristic equation of the above differential equation is:r² - (λ/9) = 0

Putting x = ∞, we get: c2 = 0

As λ > 0,

let λ = p²,

where p = sqrt(λ)

So, X(x) = c3 e^(-px/3)

Applying the condition c1 (c2 + c3) = 1,

we get:

c3 = 1/c1

c2 = 0

Therefore, u(x,t) = [e^(-p²t) / c1] [c1]

= e^(-p²t)The error function is given by:

erf(x) = 2/√π ∫₀ˣ e^(-t²) dt

Applying the change of variable as t = p z / √2,

we get:

erf(x) = 2/√π ∫₀^(x√p/√2) e^(-p²z²/2) dz

Let z' = p z / √2,

then dz = √2 / p dz'

Therefore, erf(x) = 2/√π ∫₀^(x√2/p) e^(-z'²)

dz'= √2/√π ∫₀^(x√2/p) e^(-z'²) dz'

Final Solution: u(x,t) = e^(-9t) erf((x / (2√3t)))

Therefore, the final solution of the given PDE is given by

u(x,t) = e^(-9t) erf((x / (2√3t))), where t > 0.

(w - 2v + 3u)·(-v + 2w) = -w·v + 2w·w + 2v·v - 4v·w - 3u·v + 6u·w. Substitute the given values, We have, -w·v = -2, 2w·w =

8, 2v·v = 8$,

-4v·w = -48,

-3u·v = -6,

6u·w = -18. Hence,(w - 2v + 3u)·(-v + 2w) = -2 + 8 - 48 - 6 - 18

(w - 2v + 3u)·(-v + 2w) = -66.

Therefore, the value of the given expression is -66.

The solution to the equation `-3 + 3i` in a + bi form is:`-3 + 3i = -3 + 3i` (Already in a + bi form)

To solve the equation `-3 + 3i`, you can arrange the terms in a + bi form, where a is the real part, and b is the imaginary part. Therefore,-3 + 3i can be written as `a + bi`. To find a, use the real part, which is `-3`. To find b, use the imaginary part, which is `3i`.So, `a = -3` and `b = 3i`.

Therefore, the equation can be written as:-3 + 3i = -3 + 3i

We can also write this equation in a + bi form by combining like terms. Since `3i` is the only imaginary term, we can rewrite the equation as:-3 + 3i = (0 + 3i) - 3

Now that we have a + bi form, we can see that the real part is -3, and the imaginary part is 3.

X₁, X₂, ..., Xₖ are linearly independent solutions of the differential equation X' = AX.To show that X₁, X₂, ..., Xₖ are linearly independent, we need to prove that the only solution to the equation C₁X₁ + C₂X₂ + ⋯ + CₖXₖ = 0.

Let's assume that there exists a nontrivial solution to the equation. That is, there exist constants C₁, C₂, ..., Cₖ, not all zero, such that C₁X₁ + C₂X₂ + ⋯ + CₖXₖ = 0.

Taking the derivative of this equation, we have C₁X₁' + C₂X₂' + ⋯ + CₖXₖ' = 0.

Since X₁, X₂, ..., Xₖ are solutions to X' = AX, we can substitute the expressions for X₁', X₂', ..., Xₖ' using the given equations.

C₁(eᵗU₁₂)' + C₂(eᵗ(U₂ + tU))' + ⋯ + Cₖ(eᵗ(U₁ + tU₁k-1 + ... + u₂tk-1/(k-1))!) = 0.

Expanding and simplifying, we obtain C₁eᵗU₁₂ + C₂eᵗ(U₂ + tU) + ⋯ + Cₖeᵗ(U₁ + tU₁k-1 + ... + u₂tk-1/(k-1))! = 0.

Now, let's consider the value of this equation at t = 0. Plugging in t = 0, we have C₁U₁ + C₂U₂ + ⋯ + CₖUₖ = 0.

Since U₁, U₂, ..., Uₖ are linearly independent (given), the only solution to this equation is C₁ = C₂ = ⋯ = Cₖ = 0.

Therefore, X₁, X₂, ..., Xₖ are linearly independent solutions of the differential equation X' = AX.
