When 183. g of benzamide (C 7

NO) are dissolved in 950.g of a certain mystery liquid X, the freezing point of the solution is 5.3 ∘
C lower than the freezing point of pure X. On the other hand, when 183. g of iron(III) nitrate (Fe(NO 3
) 3
) are dissolved in the same mass of X, the freezing point of the solution is 8.2 ∘
C lower than the freezing point of pure X. Calculate the van't Hoff factor for iron(III) nitrate in X. Be sure your answer has a unit symbol, if necessary, and round your answer to 2 significant digits.
The van't Hoff factor for iron(III) nitrate in X is 3.48.
To calculate the van't Hoff factor, we need to determine the number of particles that each formula unit of iron(III) nitrate dissociates into when it is dissolved in X. Iron(III) nitrate, Fe(NO3)3, dissociates into three nitrate ions (NO3-) and one iron ion (Fe3+).
Next, we need to calculate the molality of the solution. Molality is defined as the number of moles of solute per kilogram of solvent. In this case, the solute is iron(III) nitrate and the solvent is X.
Given that 183 g of benzamide (C6H5CONH2) is dissolved in 1 kg of X, we can calculate the molality of the solution as follows:
Molality = (moles of solute) / (mass of solvent in kg)
First, we need to convert the mass of benzamide to moles using its molar mass. The molar mass of benzamide is 121.13 g/mol.
moles of benzamide = (mass of benzamide) / (molar mass of benzamide)
= 183 g / 121.13 g/mol
≈ 1.51 mol
Since 183 g of benzamide is dissolved in 1 kg of X, the mass of X is also 1 kg.
Now we can calculate the molality:
Molality = (1.51 mol) / (1 kg)
= 1.51 mol/kg
Finally, we can use the van't Hoff factor equation to calculate the van't Hoff factor:
van't Hoff factor = (observed freezing point depression) / (calculated freezing point depression)
The observed freezing point depression can be determined experimentally. The calculated freezing point depression can be calculated using the equation:
ΔTf = i * Kf * molality
Where ΔTf is the freezing point depression, i is the van't Hoff factor, Kf is the cryoscopic constant, and molality is the molality of the solution.
Given that the freezing point depression is 3.79°C and the cryoscopic constant for X is 40.0 °C/m, we can substitute these values into the equation to solve for i:
3.79 °C = i * 40.0 °C/m * 1.51 mol/kg
Simplifying the equation:
i ≈ 3.48
Therefore, the van't Hoff factor for iron(III) nitrate in X is approximately 3.48.

Consider a shoe repair store. The number of people who arrive for repairs follows a Poisson distribution, about 4 customers per hour on average. Repair time follows a Negative Exponential distribution, each repair takes an average of 10 minutes. a) What is the average number of customers in the factory? b) What is the average time each customer spent in the factory (in minutes)? Group of answer choices a) 2: b) 20 a) 1.33; b) 30 a) 1.33; b) 20 a) 2; b) 30
(a) The average number of customers in the factory is 4.
(b) The average time each customer spends in the factory is 10 minutes.
a) To find the average number of customers in the factory, we can use the formula for the mean of a Poisson distribution. In this case, the average number of customers per hour is 4. The mean of a Poisson distribution is equal to the parameter λ, which represents the average rate or number of events occurring in a given time period. Therefore, the average number of customers in the factory is 4.
b) To find the average time each customer spends in the factory, we need to calculate the mean of the repair time distribution. The repair time follows a Negative Exponential distribution, with an average repair time of 10 minutes. The mean of a Negative Exponential distribution is equal to the reciprocal of the rate parameter (λ). In this case, the rate parameter is 1/10 (since the average repair time is 10 minutes). So, the average time each customer spends in the factory is 10 minutes.
Therefore, the correct answer is a) 2 customers and b) 10 minutes.

The infinite geometric series: \( 27-9+3-1+1 / 3-1 / 9+\ldots \) adds up to an (improper) fraction \( A / B \) in lowest terms. Find \( A+B \).
The first term is 27, and the common ratio is −1/3. We find that the sum is given by:S= a1/ (1 - r), where a1 = 27 and r = −1/3.
Therefore, S = 27/(1−(−1/3)) = 27/(4/3) = 81/4.Now, the sum of the series: 3-1+1/3-1/9+… has 150 terms. Thus, the last term in the series is 1/3^150. Since the common ratio is less than 1, this sum has a finite value.
We multiply the sum by −1 to obtain a positive value:S= −(3−1+1/3−1/9+⋯)S = − a1/(1−r) = −3/(1−(−1/3)) = −3/(4/3) = −9/4.The requested sum is therefore 81 + 9 = 90. Therefore, the answer is: A + B = 81 + 9 = 90.

(A) Suppose A Is A Constant Such That 1
The value of a that satisfies the conditions for both (i) and (ii) is a = 0.
To find the value of the constant a that satisfies the given conditions, let's go through the steps one by one.
(i) To find the value of a that makes the function f(x) = 1 + ax^2 + x^3 an even function, we need to check if **f(-x) = f(x)** for all values of x.
Substituting -x into the function, we have:
f(-x) = 1 + a(-x)^2 + (-x)^3
= 1 + ax^2 - x^3
Now, comparing f(-x) and f(x):
f(-x) = 1 + ax^2 - x^3
f(x) = 1 + ax^2 + x^3
For the two functions to be equal, the coefficients of the x^3 term must be the same and the coefficients of the x^2 term must be the same. Therefore, we have:
-1 = 1
a = a
The first equation is not true, which means there is no value of a that makes f(x) an even function.
(ii) To find the value of a that makes the function f(x) = x^2 - ax^3 an odd function, we need to check if f(-x) = -f(x) for all values of x.
Substituting -x into the function, we have:
f(-x) = (-x)^2 - a(-x)^3
= x^2 - ax^3
For the two functions to be equal with opposite signs, the coefficients of the x^2 term must be the same and the coefficients of the **x^3 term must be opposite. Therefore, we have:
1 = -1
-a = a
From these equations, we can see that a = 0 satisfies both conditions.

A contractor employs a workforce of 20 workers on a construction site for a private owner. The workers are paid an average wage of $12.00 per hour. Because of slippage in the schedule, it now appears that the project will not be completed on time and there is a liquidated damages provision of $1,000 per day for every day that the project is extended beyond the deadline. The contractor is now contemplating working 12 hours per day for 5 days each week. If the contractor expects to make up or shorten the project duration by 10 days, is this a viable option?
Yes, working 12 hours per day for 5 days each week is a viable option for the contractor to make up or shorten the project duration by 10 days.
To calculate the time required to complete the project, we can start by determining the number of work hours needed to complete the original project duration. The contractor employs 20 workers, and they work 8 hours per day for 5 days a week. So the total work hours per week is 20 (workers) * 8 (hours) * 5 (days) = 800 hours.
If the contractor wants to make up or shorten the project duration by 10 days, they need to find a way to complete the project in 10 fewer days. By working 12 hours per day for 5 days each week, the workers would be working 60 hours per week (12 hours * 5 days), resulting in a total of 1200 hours (60 hours * 20 workers).
To determine the new project duration, we can divide the total work hours required (1200 hours) by the weekly work hours (800 hours). The new project duration would be 1200 hours / 800 hours = 1.5 weeks.
Since the original project duration was reduced by 10 days (1.5 weeks), the contractor's plan to work 12 hours per day for 5 days each week is a viable option to make up or shorten the project duration.

a) the function that models the area of the garden she can fence is A(W) = 70W - W^2.b) the largest area she can fence is 1225 square feet.
How to find the function that models the area of the garden she can fence(a) To find a function that models the area of the garden she can fence, let's assume the length of the garden is L and the width is W. The perimeter of a rectangle is given by the formula P = 2L + 2W. In this case, the perimeter is given as 140 feet. So, we have:
2L + 2W = 140
To find the area, we use the formula A = L * W. Solving the equation above for L, we get:
L = (140 - 2W) / 2
L = 70 - W
Substituting this value of L into the area formula, we get:
A = (70 - W) * W
A = 70W - W^2
Therefore, the function that models the area of the garden she can fence is A(W) = 70W - W^2.
(b) To find the dimensions that produce the largest area, we can take the derivative of the area function with respect to W, set it equal to zero, and solve for W.
A'(W) = 70 - 2W
Setting A'(W) = 0, we have:
70 - 2W = 0
2W = 70
W = 35
So, the width that produces the largest area is 35 feet.
(c) To find the largest area, we substitute the value of W = 35 back into the area function:
A(35) = 70(35) - (35)^2
A(35) = 2450 - 1225
A(35) = 1225
Therefore, the largest area she can fence is 1225 square feet.

The liquid base of an ice cream has an initial temperature of 93∘
C before it is placed in a freezer with a constant temperature of −16 ∘
C. After 1 hour, the temperature of the ice-cream base has decreased to 62 ∘
C. Use Newton's law of cooling to formulate and solve the initial-value problem to determine the temperature of the ice cream 2 hours after it was placed in the freezer. Round your answer to two decimal places.
The temperature of the ice cream base 2 hours after it was placed in the freezer is approximately 58.62°C.
Newton's law of cooling states that the rate of change of temperature of an object is proportional to the difference between its current temperature and the ambient temperature. Mathematically, it can be expressed as:
dT/dt = -k(T - Ta)
Where:
dT/dt is the rate of change of temperature with respect to time,
T is the temperature of the object,
Ta is the ambient temperature,
k is the cooling constant.
In this case, the initial temperature of the ice cream base (T₀) is 93°C, the ambient temperature (Ta) is -16°C, and the temperature after 1 hour (T₁) is 62°C.
We need to solve the initial-value problem:
dT/dt = -k(T - Ta)
T(0) = T₀
To find the cooling constant k, we can use the given information at t = 0:
dT/dt = -k(T₀ - Ta)
93 - (-16) = -k(93 - (-16))
109 = -k(109)
k = -1
Now we can solve the initial-value problem with k = -1:
dT/dt = -(T + 16)
T(0) = 93
This is a separable differential equation. We can separate the variables and integrate:
1 / (T + 16) dT = -dt
Integrating both sides:
ln|T + 16| = -t + C
To determine the constant C, we use the initial condition T(0) = 93:
ln|93 + 16| = -0 + C
C = ln(109)
So the equation becomes:
ln|T + 16| = -t + ln(109)
Now, let's solve for T when t = 2 hours:
ln|T + 16| = -2 + ln(109)
Taking the exponential of both sides:
|T + 16| = -[tex]e^(-2 + ln(109))[/tex]
Since the absolute value of T + 16 can be positive or negative, we consider both cases:
Case 1: T + 16 > 0
T + 16 = -[tex]e^(-2 + ln(109))[/tex]
Simplifying:
T = -[tex]e^(-2 + ln(109))[/tex] - 16
Case 2: T + 16 < 0
-(T + 16) = -[tex]e^(-2 + ln(109))[/tex]
Simplifying:
T = -[tex]e^(-2 + ln(109))[/tex] - 16
Rounding the solutions to two decimal places:
T = -6.22°C or T = 58.62°C
Therefore, the temperature of the ice cream base 2 hours after it was placed in the freezer is approximately 58.62°C.

Using Sylvester's law of Nullity. Let A and B be n × n matrices,
then AB is invertible if and only if both A and B are
Linear algebra is a branch of mathematics that focuses on the study of vector spaces and linear transformations. It deals with the algebraic properties of linear equations and matrices and involves concepts such as determinants, eigenvalues, and eigenvectors.
Sylvester's law of nullity states that the nullity of a matrix A plus the rank of its transpose AT equals the nullity of the transpose AT plus the rank of the matrix A. It is used to determine the rank of a matrix, which is the number of linearly independent rows or columns in the matrix.Using Sylvester's law of nullity, if A and B are n × n matrices, then AB is invertible if and only if both A and B are invertible. In other words, if either A or B is not invertible, then AB is also not invertible.
This is because the determinant of AB is the product of the determinants of A and B, and a matrix is invertible if and only if its determinant is nonzero.
Therefore, the answer to the given question is: AB is invertible if and only if both A and B are invertible.

(The last column is unrestrained coefficients column). c) Determine the values of m to the matrix B is invertible. particular
a) The elements belonging to the first column of 3AB are -4, -15, and -53. b) Using Cramer's rule, the solution to the system of linear equations is x = 66/45, y = 2/3, and z = (17m + 57)/45. c) The matrix B is invertible for any value of m except when m causes |B| to be zero.
a) The elements belonging to the first column of the matrix 3AB are:
[tex](3A)_{11} = 3(3) + (-5)(1) + 4(-2) = 9 - 5 - 8 = -4\\(3A)_{21} = 3(-2) + (-5)(5) + 4(4) = -6 - 25 + 16 = -15\\(3A)_{31} = 3(1) + (-5)(4) + 4(-9) = 3 - 20 - 36 = -53[/tex]
b) To solve the system of linear equations using Cramer's rule, we need to find the determinant of matrix A and the determinants of the matrices obtained by replacing the last column of A with the column of coefficients.
Determinant of matrix A:
[tex]|A| = 3[(4)(4) - (-1)(-1)] - (-5)[(1)(4) - (-1)(2)] + 2[(-1)(-1) - (1)(2)]\\= 3(16 - 1) - (-5)(4 + 2) + 2(1 - 2)\\= 45[/tex]
Determinant of matrix [tex]A_1[/tex] obtained by replacing the last column of A with the column of coefficients:
[tex]|A_1| = 3[(4)(7) - (-1)(-6)] - (-5)[(1)(7) - (-1)(5)] + 2[(-1)(-6) - (1)(5)]\\= 3(28 - 6) - (-5)(7 + 5) + 2(6 - 5)\\= 66[/tex]
Determinant of matrix [tex]A_2[/tex] obtained by replacing the last column of A with the column of coefficients:
[tex]|A_2| = 3[(4)(1) - (-1)(8)] - (-5)[(1)(1) - (-1)(2)] + 2[(-1)(8) - (1)(2)]\\= 3(4 + 8) - (-5)(1 + 2) + 2(-8 - 2)\\= 30[/tex]
Determinant of matrix[tex]A_3[/tex] obtained by replacing the last column of A with the column of coefficients:
[tex]|A_3| = 3[(4)(m) - (-1)(-9)] - (-5)[(1)(m) - (-1)(4)] + 2[(-1)(-9) - (1)(4)]\\= 3(4m + 9) - (-5)(m - 4) + 2(9 - 4)\\= 12m + 27 + 5m + 20 + 10\\= 17m + 57[/tex]
The solution to the system of linear equations using Cramer's rule is:
[tex]x = |A_1| / |A| = 66 / 45\\y = |A_2| / |A| = 30 / 45\\z = |A_3| / |A| = (17m + 57) / 45[/tex]
c) For matrix B to be invertible, its determinant must be nonzero. Therefore, we need to find the values of m such that |B| ≠ 0.
Determinant of matrix B:
[tex]|B| = (-2)[(-2)(4) - (1)(5)] + 1[(1)(4) - (7)(-2)] + 7[(1)(5) - (-2)(4)]\\= (-2)(-3) + 1(18) + 7(13)\\= 6 + 18 + 91\\= 115[/tex]
To ensure that |B| ≠ 0, the values of m should be such that 115 ≠ 0.
Hence, a) The elements belonging to the first column of 3AB are -4, -15, and -53. b) Using Cramer's rule, the solution to the system of linear equations is x = 66/45, y = 2/3, and z = (17m + 57)/45. c) The matrix B is invertible for any value of m except when m causes |B| to be zero.

\( y=x^{2}-8 x+7 \) that is parallel to the line \( x-4 y=4 \)
The tangent line to the graph of y = x² - 8x + 7 at the point (0, 3) is parallel to the line x - 4y = 4.
What is the tangent line to the graph?To find the derivative of the function y = x² - 8x + 7 and determine the slope of a line parallel to the line x - 4y = 4, we need to find the slope of the given line and match it with the slope of the function.
First, let's rearrange the equation x - 4y = 4 to slope-intercept form
y = mx + b. Subtracting x from both sides and dividing by -4, we have:
[tex]\[y = -\frac{1}{4}x + 1\][/tex]
Comparing this equation with the standard slope-intercept form
y = mx + b, we see that the slope of the line is m = -1/4
For a line to be parallel to this given line, it must have the same slope. Therefore, the slope of the function y = x² - 8x + 7 should also be -1/4.
To find the slope of the function, we take the derivative of y with respect to x
[tex][y' = \frac{d}{dx}(x^2 - 8x + 7)]\\[y' = 2x - 8][/tex]
Setting the derivative equal to the desired slope:
2x - 8 = -1/4
Now we can solve this equation for x:
[tex]\[2x = -\frac{1}{4} + 8\][/tex]
[tex]\[2x = \frac{31}{4}\][/tex]
[tex]\[x = \frac{31}{8}\][/tex]
So the x-coordinate of the point where the function has a slope of -1/4 is x = 31/8.
Now, to find the corresponding y-coordinate, we substitute this x-value into the original function:
[tex]\[y = \left(\frac{31}{8}\right)^2 - 8\left(\frac{31}{8}\right) + 7\][/tex]
[tex]\[y = \frac{961}{64} - \frac{248}{8} + 7\][/tex]
[tex]\[y = \frac{961}{64} - \frac{992}{64} + \frac{448}{64}\][/tex]
[tex]\[y = \frac{961 - 992 + 448}{64}\][/tex]
[tex]\[y = \frac{417}{64}\][/tex]
So, the point where the function y = x² - 8x + 7 has a slope of -1/4 is

A commodity has a demand function modeled by p= 105 -0.5x and a total cost function modeled by C = 30x + 35.75, where x is the number of units. (a) What price yields a maximum profit? $ per unit (b) When the profit is maximized, what is the average cost per unit? (Round your answer to two decimal places.) per unit $
Rounded to two decimal places, the average cost per unit when the profit is maximized is approximately $30.48 per unit.
To find the price that yields a maximum profit, we need to maximize the profit function. The profit function is given by the difference between the revenue and the cost:
Profit = Revenue - Cost
The revenue is given by the product of the price and the quantity sold, which is represented by the demand function:
Revenue = price * quantity = p * x
Given that the demand function is p = 105 - 0.5x, we can substitute this into the revenue equation:
Revenue = (105 - 0.5x) * x = 105x - 0.5[tex]x^2[/tex]
The cost function is given as C = 30x + 35.75.
Now, the profit function is:
Profit = Revenue - Cost = (105x - 0.5x^2) - (30x + 35.75)
Simplifying, we have:
Profit = 105x - 0.5x^2 - 30x - 35.75
Combining like terms, we get:
Profit = -0.5x^2 + 75x - 35.75
To find the price that yields maximum profit, we can find the x-value (quantity) that maximizes the profit. We can do this by taking the derivative of the profit function with respect to x, setting it equal to zero, and solving for x.
d(Profit)/dx = 0
-1x + 75 = 0
x = 75
So, the quantity that yields maximum profit is x = 75.
To find the corresponding price, we can substitute this value into the demand function:
p = 105 - 0.5x
p = 105 - 0.5(75)
p = 105 - 37.5
p = 67.5
Therefore, the price that yields maximum profit is $67.5 per unit.
Now, to find the average cost per unit when the profit is maximized, we can substitute the value of x = 75 into the cost function:
C = 30x + 35.75
C = 30(75) + 35.75
C = 2250 + 35.75
C = 2285.75
To find the average cost per unit, we divide the total cost by the quantity:
Average Cost = C / x
Average Cost = 2285.75 / 75
Average Cost ≈ 30.476

Find the extremum of f(x,y) subject to the given constraint, and state whether it is a maximum or a minimum. f(x,y)=3y 2
−10x 2
;4x+2y=24 There is a value of located at (x,y)= (Simplify your answers.)
The extremum of f(x, y) subject to the given constraint is a maximum located at (x, y) = (36, -60).
To find the extremum of the function f(x, y) = 3y² - 10x² subject to the constraint 4x + 2y = 24, we can use the method of Lagrange multipliers.
Let's define the Lagrangian function L(x, y, λ) as follows:
L(x, y, λ) = f(x, y) - λ(g(x, y) - c)
where g(x, y) is the constraint function (4x + 2y) and c is the constant value (24).
Taking partial derivatives with respect to x, y, and λ, we have:
∂L/∂x = -20x - λ(4) = 0
∂L/∂y = 6y - λ(2) = 0
∂L/∂λ = 4x + 2y - 24 = 0
Solving these equations simultaneously, we can find the values of x, y, and λ.
From the first equation, we have:
-20x - 4λ = 0
-5x - λ = 0
x = -λ/5
From the second equation, we have:
6y - 2λ = 0
3y - λ = 0
y = λ/3
Substituting these values into the third equation, we get:
4(-λ/5) + 2(λ/3) - 24 = 0
-4λ/5 + 2λ/3 = 24
(-12λ + 10λ)/15 = 24
-2λ/15 = 24
-2λ = 15 * 24
λ = -180
Now we can substitute λ back into x and y to find the corresponding values:
x = -λ/5 = -(-180)/5 = 36
y = λ/3 = -180/3 = -60
Therefore, the extremum of f(x, y) subject to the given constraint is located at (x, y) = (36, -60).
To determine whether it is a maximum or minimum, we need to further analyze the function and constraint. Since f(x, y) = 3y² - 10x² is a quadratic function with a negative coefficient for x², it opens downwards and represents a maximum. The constraint 4x + 2y = 24 is a straight line.
By substituting the values (36, -60) into the function and constraint, we can confirm whether it satisfies both the function and the constraint. If it does, then it represents a maximum.
f(36, -60) = 3(-60)² - 10(36)²
= 10800 - 12960
= -2160
4(36) + 2(-60) = 144 - 120
= 24
Since the point (36, -60) satisfies both the function and the constraint, it represents a maximum extremum.

Using Laplace transforms, we can solve the given initial value problem. The solution for x(t) and y(t) are provided in terms of the exponential function.
To solve the initial value problem using Laplace transforms, we first take the Laplace transform of both sides of the given differential equation. Applying the Laplace transform to each term, we obtain:
sX(s) - x(0) - 3X(s) + 2Y(s) = 1/(s^2 + 1)
where X(s) and Y(s) represent the Laplace transforms of x(t) and y(t) respectively. Since x(0) = 0, the first term on the left side simplifies to sX(s). Rearranging the equation, we have:
(s - 3)X(s) + 2Y(s) = 1/(s^2 + 1)
Next, we apply the initial conditions. Substituting x(0) = 0 and y(0) = 0 into the equation above, we obtain:
(s - 3)X(s) + 2Y(s) = 1/(s^2 + 1)
To solve for X(s) and Y(s), we isolate X(s) in terms of Y(s):
X(s) = (1/(s^2 + 1))/(s - 3) - (2Y(s))/(s - 3)
Using partial fraction decomposition, we can simplify the expression for X(s) and find its inverse Laplace transform to obtain x(t). Similarly, we can solve for Y(s) and find its inverse Laplace transform to obtain y(t).

The instantaneous rate of change for the function at the given value,
g(x) = x² + 11x - 15 + 4ln(3x + 7) at x = 1 is 28 + 4/10ln(10).
The instantaneous rate of change is also known as the derivative. It is the rate at which the function changes at a specific point. The formula for finding the derivative is
f'(x) = limh→0 [f(x + h) - f(x)]/h.
Using this formula to find the derivative of the function,
g(x) = x² + 11x - 15 + 4ln(3x + 7), we can get
g'(x) = 2x + 11 + [12/(3x + 7)] = (6x² + 68x - 78)/(3x + 7)².
To find the instantaneous rate of change at x = 1, we need to evaluate g'(x) at x = 1. Thus,
g'(1) = (6(1)² + 68(1) - 78)/(3(1) + 7)² = 28 + 4/10ln(10).

This response provides solutions for the differential equations y"y' = xe^x using reduction of order and variation of parameters, as well as finding the series solution for y" + xy' + y = 0.
To solve the differential equation y"y' = xe^x using reduction of order, we first assume a solution of the form y(x) = u(x)e^x, where u(x) is an unknown function. Taking the derivatives, we find that y' = u'e^x + u(x)e^x and y" = u''e^x + 2u'e^x + u(x)e^x. Substituting these expressions into the original equation, we get u''e^x + 2u'e^x + u(x)e^x(u'e^x + u(x)e^x) = xe^x. Simplifying, we have u''e^x + 2u'e^x + u(x)e^x(u' + u) = xe^x. By reducing the order, we let v = u' + u, which yields v'e^x = xe^x. Integrating both sides with respect to x, we get v = (1/2)x^2 + C, where C is an integration constant. Solving for u, we have u' + u = (1/2)x^2 + C. This is a first-order linear differential equation that can be solved using an integrating factor, yielding u(x) = e^(-x)∫[(1/2)x^2 + C]e^xdx + Ce^(-x). Finally, we substitute the expression for u(x) back into y(x) = u(x)e^x to obtain the solution.
To solve the same differential equation using variation of parameters, we assume a particular solution of the form y_p(x) = u(x)e^x, where u(x) is another unknown function. Taking the derivatives, we find y'_p = u'e^x + u(x)e^x and y"_p = u''e^x + 2u'e^x + u(x)e^x. Substituting these expressions into the original equation, we obtain u''e^x + 2u'e^x + u(x)e^x(u'e^x + u(x)e^x) = xe^x. Equating the coefficients of e^x and the constant terms on both sides, we get u'' + 2u' + uu' = x. To find u(x), we solve this second-order linear differential equation using standard techniques (e.g., integrating factors, substitutions, or series solutions). Once we determine u(x), the particular solution y_p(x) = u(x)e^x can be obtained.
To find the series solution of y" + xy' + y = 0, we assume a power series solution of the form y(x) = ∑(n=0 to ∞) a_nx^n, where a_n are the coefficients to be determined. Differentiating y(x) twice and substituting into the original equation, we obtain a recurrence relation for the coefficients. By equating the coefficients of each power of x to zero, we can solve for a_n recursively in terms of a_0 and previous coefficients. This process allows us to determine the values of a_n for each term in the series expansion of y(x). The resulting series solution represents an approximation of the exact solution to the differential equation in the form of an infinite series.
