To prove that xmin is a minimizer of g as well, we need to show that g(xmin) is the minimum value of g for all x.

Let's assume that there exists some x1 such that g(x1) < g(xmin). We can then write:

g(x1) = c·f(x1) + d
g(xmin) = c·f(xmin) + d

Since xmin is a minimizer of f, we know that f(x1) ≥ f(xmin) for all x. Thus:

c·f(x1) + d ≥ c·f(xmin) + d

But we assumed that g(x1) < g(xmin), so:

c·f(x1) + d < c·f(xmin) + d

This is a contradiction, so our assumption that g(x1) < g(xmin) must be false. Therefore, xmin is a minimizer of g as well.
Hi! To prove that if xmin is a minimizer of f, then it is also a minimizer of g, we need to show that g(xmin) is the smallest value of g(x) for any real number x.

Since xmin is a minimizer of f, we have:
f(xmin) ≤ f(x) for all x in the domain of real numbers.

Now, consider g(x) = c·f(x) + d, where c and d are positive constants. We can write g(xmin) and g(x) as follows:
g(xmin) = c·f(xmin) + d
g(x) = c·f(x) + d

Since c > 0, we can multiply both sides of the inequality f(xmin) ≤ f(x) by c without changing the direction of the inequality:
c·f(xmin) ≤ c·f(x)

Now, add d to both sides of the inequality:
c·f(xmin) + d ≤ c·f(x) + d

This can be written as:
g(xmin) ≤ g(x) for all x in the domain of real numbers.

Hence, we have shown that xmin is also a minimizer of g.

A.The nearest tenth of an inch, we have:

Ground covered per rotation ≈ 39.3 inches

b. the wheel made approximately 24 rotations while measuring a distance of 78.6 feet.

c. The radius of the wheel is approximately 15.9 centimeters

How to find nearest tenth:

A. To determine how much ground is covered with every rotation of the wheel, we need to find the circumference of the wheel.

Circumference = π × diameter

= 3.14 × 12.5 inches

≈ 39.25 inches

Rounding to the nearest tenth of an inch, we have:

Ground covered per rotation ≈ 39.3 inches

B. If the trundle wheel measures a distance of 78.6 feet, we need to convert this distance to inches and divide by the ground covered per rotation in inches to find the number of rotations:

78.6 feet × 12 inches/foot = 943.2 inches

Number of rotations = 943.2 inches ÷ 39.25 inches/rotation

≈ 24 rotations

Therefore, the wheel made approximately 24 rotations while measuring a distance of 78.6 feet.

C. If one revolution of the wheel measures 1 meter, then the circumference of the wheel is equal to 1 meter.

Circumference = 1 meter

We can use the formula for circumference to solve for the radius:

Circumference = 2π × radius

1 meter = 2π × radius

radius = 1 meter ÷ 2π

radius ≈ 0.159 meters

To convert to centimeters, we multiply by 100:

radius ≈ 15.9 centimeters (rounded to the nearest centimeter)

Therefore, the radius of the wheel is approximately 15.9 centimeters.

The function f(x) = x⁴ − 3x² satisfies the criteria of Rolle's Theorem over [−1, 1], and there are two values of c (0 and -1) where f ′ (c) = 0.

To apply Rolle's theorem, we need to check if the following two conditions are met:

In this case, we have:

f(x) = x⁴ - 3x²

f'(x) = 4x³ - 6x

  1.  f(x) is continuous on [-1, 1]:

   The function f(x) is a polynomial, which is continuous on its domain of definition.

    Therefore, f(x) is continuous on [-1, 1].

  2. f(x) is differentiable on (-1, 1):

   The function f(x) is a polynomial, which is differentiable on its domain of definition. Therefore, f(x) is differentiable on (-1, 1).

Since both conditions are met, we can apply Rolle's theorem to find all values of c in the interval [-1, 1] where f'(c) = 0.

By Rolle's theorem, there exists at least one point c in (-1, 1) such that f'(c) = 0 if and only if f(-1) = f(1), which means that the function has the same value at the endpoints of the interval.

We have:

f(-1) = (-1)⁴ - 3(-1)² = 4

f(1) = 1⁴ - 3(1)² = -2

Since f(-1) ≠ f(1), we cannot apply Rolle's theorem to conclude that there exists a point c in (-1, 1) such that f'(c) = 0.

However, we can still find the values of c in (-1, 1) where f'(c) = 0 by solving the equation f'(c) = 0.

f'(c) = 4c³- 6c = 0

c(4c² - 6) = 0

c = 0 or c = ± √(3/2)

Therefore, the values of c in (-1, 1) where f'(c) = 0 are c = 0 and c = ±√(3/2).

The value of the given definite integral, evaluated from 2 to 11, is approximately -1.112 × 10¹⁶ j - 9.516 k - 1.333.

We are given the definite integral to evaluate:

∫₂¹¹ [(sec²(t) i) + (t(t² + 1)⁵ j) + (6 ln(t) k)] dt + 2 ∫₂¹¹ [(-1/2) sec²(t) dt] - 1/12 ∫₂¹¹ [12/t²] dt

We first integrate each component of the integral separately with respect to t:

∫ sec²(t) dt = tan(t) + C₁

∫ t(t² + 1)⁵ dt = 1/6 (t² + 1)⁶ + C₂

∫ 6 ln(t) dt = 6 ln(t) - 6 t + C₃

∫ (-1/2) sec²(t) dt = (-1/2) tan(t) + C₄

∫ (12/t²) dt = -12/t + C₅

where C₁, C₂, C₃, C₄, and C₅ are constants of integration.

We substitute the limits of integration (2 and 11) into the respective expressions and compute the differences:

∫₂¹¹ [(sec²(t) i) + (t(t² + 1)⁵ j) + (6 ln(t) k)] dt = [(tan(11) - tan(2)) i + (1/6)(11² + 1)⁶ - (1/6)(2² + 1)⁶ j + (6 ln(11) - 6 ln(2) - 66) k]

2 ∫₂¹¹ [(-1/2) sec²(t) dt] = 2[(-1/2) tan(11) + (1/2) tan(2)]

1/12 ∫₂¹¹ [12/t²] dt = 1/12 [(-12/11) + 12/2]

Substituting the values obtained from Separating the values of integral into the original expression, we obtain:

[(tan(11) - tan(2)) i + (1/6)(11² + 1)⁶ - (1/6)(2² + 1)⁶ j + (6 ln(11) - 6 ln(2) - 66) k] + 2[(-1/2) tan(11) + (1/2) tan(2)] - 1/12 [(-12/11) + 12/2]

[(1/6)(11² + 1)⁶ - (1/6)(2² + 1)⁶ j + (6 ln(11) - 6 ln(2) - 66) k] - (11/6) + 1

Finally, we approximate the value of the expression as:

Unit normal: N= 2i+3j + 1/√73k

The standard form of the equation of the tangent plane at (1,1,3) is x - 4y + z - 3 = 0.

To find the normal vector, we first need to find the partial derivatives of the surface equation with respect to x and y. Using the chain rule, we get:

∂z/∂x = 2xe^(x²−y²) ∂z/∂y = -2ye^(x²−y²)

At the given point (1,1,3), these partial derivatives evaluate to:

∂z/∂x = 2e^0 = 2 ∂z/∂y = -2e^0 = -2

So the gradient vector of the surface at (1,1,3) is:

grad(z) = <2, -2, ze^(x²−y²)> = <2, -2, 3>

To find a unit normal vector, we need to divide the gradient vector by its magnitude:

|grad(z)| = √(2² + (-2)² + 3²) = √(17 + 9 + 4) = √(30)

So the unit normal vector is:

N = (1/√(30)) <2, -2, 3> = (1/√(30)) <2, -2, 3>

Note that there are two possible unit normal vectors, since we could also multiply this vector by -1.

Now we need to find the equation of the tangent plane. We know that the tangent plane has the form:

ax + by + cz + d = 0

where (a, b, c) is the normal vector we just found, and (x, y, z) is any point on the plane. We also know that the plane passes through the point (1,1,3), so we can substitute these values into the equation to get:

a(1) + b(1) + c(3) + d = 0

Simplifying this equation, we get:

a + b + 3c + d = 0

To fix a unique solution, we are given the coefficient of the z component, which is 1. So we can set c = 1 and solve for the other coefficients:

a + b + 3 = 0 a + b = -3

We can choose any values for a and b that satisfy this equation, as long as they are not both zero. For example, we can choose a = 1 and b = -4, or a = -3 and b = 0. Either way, we get:

The regression line can also be used to assess the strength and direction of the relationship between the two variables. If the slope is positive, it indicates that there is a positive relationship between the number of lamb's and corn yield and vice versa.

To find the equation for the least-squares regression line for predicting corn yield from the number of lamb's, you would first need to gather data on the number of lamb's and the resulting corn yield for several observations. Once you have this data, you can use statistical software or a calculator to calculate the regression line.
The equation for the least-squares regression line can be represented as:
y = a + bx
Where y represents the predicted corn yield, x represents the number of lamb's, a is the y-intercept, and b is the slope of the line. The slope of the line tells us the rate at which corn yield changes with respect to the number of lamb's.
To calculate the values of a and b, we need to use the least-squares method. This involves finding the values of a and b that minimize the sum of the squared differences between the actual and predicted corn yield for each observation. The least-squares method provides the best-fitting line that represents the relationship between the two variables.
Once you have calculated the values of a and b, you can plug them into the equation for the regression line and use it to predict the corn yield for a given number of lamb's. The regression line can also be used to assess the strength and direction of the relationship between the two variables. If the slope is positive, it indicates that there is a positive relationship between the number of lamb's and corn yield. If the slope is negative, it indicates that there is a negative relationship between the two variables.

To find the equation of the tangent plane to the surface z = y ln(x) at the point (1, 7, 0), we first need to find the partial derivatives of z with respect to x and y:

∂z/∂x = y/x
∂z/∂y = ln(x)

To find the volume of the pyramid bounded by the plane x + 2y + 6z = 12 in the first octant (x ≥ 0, y ≥ 0, z ≥ 0), we first need to determine the vertices where the plane intersects the coordinate axes.

For x-axis (y = 0, z = 0):
x + 2(0) + 6(0) = 12
x = 12

For y-axis (x = 0, z = 0):
0 + 2y + 6(0) = 12
2y = 12
y = 6

For z-axis (x = 0, y = 0):
0 + 2(0) + 6z = 12
6z = 12
z = 2

So, the vertices of the pyramid are A(12, 0, 0), B(0, 6, 0), and C(0, 0, 2).

Now, to calculate the volume of the pyramid, we use the formula:

Volume = (1/3) × Base Area × Height

Since the base of the pyramid is a right-angled triangle with sides 12 and 6, the base area is:

Base Area = (1/2) × Base × Height = (1/2) × 12 × 6 = 36 square units

The height of the pyramid is equal to the z-coordinate of vertex C, which is 2.

Now, we can calculate the volume:

Let's assume the length of the vegetable patch is L and the width is W.

Given, the perimeter of the rectangular vegetable patch = 40 meters.

Perimeter = 2(L+W) = 40

Simplifying the above equation, we get

L+W = 20 (Equation 1)

Also, given that the area of the vegetable patch = 64 square meters.

Area = L*W = 64

From Equation 1, we can write W = 20-L

Substituting W in terms of L in the area equation, we get

L*(20-L) = 64

Expanding the above equation, we get

-L^2 + 20L - 64 = 0

Solving the quadratic equation, we get two possible values for L.

L = 8 or L = 12

If L = 8, then W = 20 - L = 12

To find the average value of a function f(x) over an interval [a, b], we use the formula:

avg(f) = (1 / (b - a)) * ∫[a, b] f(x) dx

where ∫[a, b] f(x) dx represents the definite integral of f(x) over the interval [a, b].

a) For the function f(t) = 5 sin(3t), the interval is [0, 2π/3] because one period of sin(3t) is 2π/3.

avg(f) = (1 / (2π/3 - 0)) * ∫[0, 2π/3] 5 sin(3t) dt

Using integration by substitution, we get:

avg(f) = (1 / (2π/3)) * [-5/3 cos(3t)] |[0, 2π/3]

avg(f) = (1 / (2π/3)) * [-5/3 cos(2π) + 5/3 cos(0)]

avg(f) = (1 / (2π/3)) * (5/3 - (-5/3))

avg(f) = 5/2π

Therefore, the average value of f(t) = 5 sin(3t) over the interval [0, 2π/3] is 5/2π.

b) For the function g(t) = 4 cos(8t), the interval is [0, π/4] because one period of cos(8t) is π/4.

avg(g) = (1 / (π/4 - 0)) * ∫[0, π/4] 4 cos(8t) dt

Using integration by substitution, we get:

avg(g) = (1 / (π/4)) * [1/2 sin(8t)] |[0, π/4]

avg(g) = (1 / (π/4)) * [1/2 sin(2π) - 1/2 sin(0)]

avg(g) = (1 / (π/4)) * (0 - 0)

avg(g) = 0

Therefore, the average value of g(t) = 4 cos(8t) over the interval [0, π/4] is 0.

c) For the function h(t) = cos^2(2t), the interval is [0, π/4] because one period of cos^2(2t) is π/4.

avg(h) = (1 / (π/4 - 0)) * ∫[0, π/4] cos^2(2t) dt

Using the identity cos^2(x) = (1/2) + (1/2)cos(2x), we can write:

cos^2(2t) = (1/2) + (1/2)cos(4t)

Substituting this into the integral, we get:

avg(h) = (1 / (π/4)) * ∫[0, π/4] [(1/2) + (1/2)cos(4t)] dt

avg(h) = (1 / (π/4)) * [(1/2)t + (1/8) sin(4t)] |[0, π/4]

avg(h) = (1 / (π/4)) * [(1/2)(π/4) + (1/8) sin(π)]

avg(h) = (1 / (π/4)) * [(π/8) + 0]

avg(h) = 2/π

To determine the values of p for which the integral ∫[1 to ∞] (1/(x(ln(x))^p)) dx converges, we need to evaluate the improper integral using limits. The integral converges if and only if the limit of the integral exists and is a finite number.

Integral(1/(x(ln(x))^p), x) from x = 1 to infinity.

Step 1: Set up the integral
∫[1 to ∞] (1/(x(ln(x))^p)) dx

Step 2: Use a limit to handle the infinity in the integral
lim (b→∞) ∫[1 to b] (1/(x(ln(x))^p)) dx

Step 3: Evaluate the integral using the substitution method
Let u = ln(x), so du = (1/x) dx.
The limits of integration will change: u(1) = ln(1) = 0, and u(b) = ln(b) as b→∞.

So, our integral becomes:
lim (b→∞) ∫[0 to ln(b)] (1/u^p) du

Step 4: Evaluate the new integral
∫(1/u^p) du = (u^(1-p))/(1-p), since p ≠ 1

Step 5: Plug in the limits of integration
lim (b→∞) [(ln(b)^(1-p))/(1-p) - (0^(1-p))/(1-p)]

Step 6: Determine the values of p for which the limit converges
If p < 1, ln(b)^(1-p) goes to infinity as b→∞, so the limit does not converge.
If p > 1, ln(b)^(1-p) goes to 0 as b→∞, so the limit converges.

Therefore, the integral converges for values of p > 1.

According to the given function, the value of ∂Q / ∂x is 1, and the value of ∂P / ∂y is -1

In the given equation, Q = x + y and P = x − y, we can think of Q and P as functions of x and y. That is, for every combination of x and y, we get a corresponding value of Q and P.

Now, the partial derivative of Q with respect to x (denoted as ∂Q/∂x) tells us how Q changes when we vary x while keeping y constant. Similarly, the partial derivative of P with respect to y (denoted as ∂P/∂y) tells us how P changes when we vary y while keeping x constant.

In this case, ∂Q/∂x = 1, which means that if we increase x by a small amount, Q will also increase by the same amount. The value of y does not affect this relationship. Similarly, ∂P/∂y = -1, which means that if we increase y by a small amount, P will decrease by the same amount. The value of x does not affect this relationship.

The average rates of change for f(x)=0.1x squared, g(x)=0.3x squared is 0.5 and 1.3 over the interval [1,4].

In order to calculate the average rate of change of a function f(x) over an interval [a,b] we need to implement the formula

A(x) = {f(b) - f(a)] / (b – a)}

Here,

A(x)= average rate of change,

f(a) = value of function,

f(b) = value of function

given, from the question

f(x) = 0.1x^2

g(x) = 0.3x^2

The calculated interval is 1 ≤ x ≤ 4.

Therefore,

for f(x), we have staged the values as

A(x) = {f(4) - f(1)] / (4 - 1)}

= {(0.1 * 4^2) - (0.1 * 1^2)] / (4 - 1)}

= (1.6 - 0.1) / 3

= 0.5

for g(x), we have staged the values as

A(x) = {g(4) - g(1)] / (4 - 1)}

= {(0.3 * 4^2) - (0.3 * 1^2)] / (4 - 1)}

= (4.2 - 0.3) / 3

= 1.3

The average rates of change for f(x)=0. 1x squared, g(x)=0. 3x squared is 0.5 and 1.3 over the interval [1,4].

The  value of the line integral along C is 178/3.

Here, we have,

To evaluate the line integral, we need to compute the integral of the given function along each segment of the curve separately and then sum them up.

First, let's consider the line segment from (0, 0) to (5, 1). Parameterizing this segment as x = t and y = t/5 (where t ranges from 0 to 5), we can rewrite the line integral as ∫₀⁵(t + 5(t/5)) dt + ∫₀⁵(t²)(1/5) dt. Simplifying, we get the value of the integral over this segment as (25/2) + (25/3) = 175/6.

Next, for the line segment from (5, 1) to (6, 0), we parameterize it as x = 5 + t and y = 1 - t (where t ranges from 0 to 1). Substituting these values into the line integral expression, we get ∫₀¹((5 + t) + 5(1 - t)) dt + ∫₀¹((5 + t)²)(-dt). Evaluating this integral gives us the value (69/2) - (32/3) = 181/6.

Finally, we add the values obtained from each segment: 175/6 + 181/6 = 356/6 = 178/3.

Therefore, the value of the line integral along C is 178/3.

The derivative of the position-time relationship with respect to time (dt) is 2.5m/s.

The position-time relationship for the bowling ball is given by x(t) = vot + xo, where vo = 2.5m/s and xo = -5.0m.

To find the derivative with respect to time (dt), we need to perform the operation of differentiation:

x(t) = (2.5m/s)t - 5.0m

Now, differentiate with respect to time (t):

dx/dt = d(2.5m/s*t)/dt - d(5.0m)/dt

Using the differentiation rules for a polynomial (sum of terms) and a constant:

dx/dt = 2.5m/s * d(t)/dt - 0

Since d(t)/dt = 1:

dx/dt = 2.5m/s * 1 - 0 = 2.5m/s

Thus, the derivative of the position-time relationship with respect to time (dt) is 2.5m/s.

A score of 81 is not considered unusual as its Z-score of 1.74 is less than 2, although it is above the class mean and higher than most of the scores in the class.

What is the Z-score for a score of 81 with a class mean of 77 and standard deviation of 2.3, and is a score of 81 considered unusual?

To calculate the Z-score for a person who received a score of 81 on the recent quiz with a class mean of 77 and standard deviation of 2.3, we can use the formula:

Z-score = (score - class mean) / standard deviation

Substituting the given values, we get:

Z-score = (81 - 77) / 2.3
Z-score = 1.74

Rounding to 2 decimal places, the Z-score for the person who received a score of 81 is 1.74.

To determine if a quiz score of 81 is considered unusual, we need to compare the Z-score to a standard value. Generally, a Z-score greater than 2 or less than -2 is considered unusual.

In this case, the Z-score of 1.74 is less than 2, so a score of 81 is not considered unusual. It is above the class mean and higher than most of the scores in the class, but it is not so far from the mean that it is considered unusual.

The integral ∫₀^∞ 8sin²(x) dx is divergent.

To determine whether the integral is convergent or divergent, and evaluate it if it's convergent, let's analyze the given integral ∫₀^∞ 8sin²(x) dx. Your answer will include the terms "convergent" or "divergent."
1: Rewrite the integral
First, rewrite the integral using the double-angle identity: sin²(x) = (1 - cos(2x))/2. Thus, the integral becomes:
∫₀^∞ 8(1 - cos(2x))/2 dx
2: Simplify the integral
Simplify the expression to obtain:
∫₀^∞ 4 - 4cos(2x) dx
3: Split the integral into two parts
Separate the integral into two parts:
∫₀^∞ 4 dx - ∫₀^∞ 4cos(2x) dx
4: Evaluate the two integrals
Evaluate each integral separately:
For the first integral:
∫₀^∞ 4 dx = 4x | evaluated from 0 to ∞ = ∞
For the second integral, use integration by substitution:
Let u = 2x, so du = 2 dx
The limits of integration also change: when x = 0, u = 0; when x → ∞, u → ∞
The integral becomes:
-2 ∫₀^∞ cos(u) du
Now, evaluate the integral:
-2 (sin(u) | evaluated from 0 to ∞)
However, sin(u) oscillates between -1 and 1 as u goes from 0 to ∞, so this integral is undefined.
5: Determine convergence or divergence
Since the first integral evaluates to ∞ and the second integral is undefined, their sum is also undefined. Thus, the original integral is divergent.

The system of equations 6x + 5y = 9 and −11x − 10y = −20 has exactly one solution.

Given that

6x + 5y = 9

−11x − 10y = −20

To determine if the system of equations has no solutions, infinitely many solutions, or exactly one solution, we can use a common method called elimination.

First, we can multiply the first equation by 2 to eliminate y:

12x + 10y = 18

Next, we can add the second equation to the modified first equation to eliminate x:

12x + 10y -11x -10y = 18 - 20

Simplifying both sides:

x = -2

Therefore, the system has exactly one solution

If the two numbers are negative it gives only negative number.

It is always not true.

If we subtract a smaller negative integer from the larger one, the answer will be a positive integer.

But when we subtract larger negative integer with smaller one, the answer will be a negative integer.

Let us take two examples:

Let -1 and -2 be two integers, then the difference between them will be

-1 - (-2)

= -1 + 2

= 1[Positive integer]

But when we subtract -2 from -1, then

-2 - (-1)

= -2 + 1

= -1 [negative integer]

The results are not reliable because the sample is not random, describes the validity of the results from this poll that the screen capture is from an online polling organization. Therefore, the option is (a) is correct.

To obtain reliable results, it is important to have a random sample, which means that each person in the population being studied has an equal chance of being selected to participate in the poll. However, in this case, the sample is not random since the people who respond to online polls may not be representative of the entire population.

For example, those who are more likely to participate in an online poll may have certain demographic characteristics or opinions that differ from the general population. Additionally, without information on the sample size, it is difficult to assess the precision of the results.

Regarding option C, it is not necessarily true that online polls are more reliable than telephone polls. Both types of polls have their advantages and limitations, and the reliability depends on various factors such as the quality of the sample, the wording of the questions, and the methods used to analyze the data.

Regarding option D, while the organization conducting the poll may have biases, it does not necessarily mean that the results are invalid.It is important to consider the potential biases and methodology of the organization to assess the reliability of the results.

The base case for the set S is the empty string λ.

The recursive definition for S is as follows:
1. For any n ≥ 0, the string aabb can be in S.
2. If w is a string in S, then adding an a to the beginning of w yields another string in S.
3. If w is a string in S, then adding two b's to the end of w yields another string in S.

In other words, S is the smallest set of strings that satisfies the base case and can be obtained by applying the above three rules recursively.
For example, starting with the empty string λ:
- applying rule 1, we get abb
- applying rule 2, we get aabb
- applying rule 3 to aabb, we get aaabbb
- applying rule 2 to aaabbb, we get aaaabbbb
- applying rule 3 to aaaabbbb, we get aaaaabbbbb

And so on for any n ≥ 0.
This recursive definition ensures that every string in S has n a's followed by 2n b's, where n is a non-negative integer.
A recursive definition for the set S of all strings with n a's followed by 2n b's is as follows:
Base case: When n = 0, the string is an empty string (λ).
Recursive step: For n > 0, the string s ∈ S can be defined as s = a * s' * bb, where s' ∈ S is a string with n-1 a's followed by 2(n-1) b's.

Thus, S consists of strings {λ, abb, aabbbb, aaabbbbbb, ...}.

The solution of the differential equation [tex]y^5 x \frac{d y}{d x}=1+x[/tex] is [tex]y^6=6 \log x+6 x+723[/tex].

In mathematics, a differential equation is an equation that relates one or more unknown functions and their derivatives.

A differential equation is an equation that contains one or more terms and the derivatives of one variable (i.e., dependent variable) with respect to the other variable (i.e., independent variable).

To solve the differential equation [tex]y^5 x \frac{d y}{d x}=1+x[/tex], firstly, separate the variables as follows:

[tex]\begin{aligned}& y^5 d y=\left(\frac{1+x}{x}\right) d x \\& y^5 d y=\left(\frac{1}{x}+1\right) d x\end{aligned}[/tex]

Integrating both sides, we get the following:

[tex]\begin{aligned}& \int y^5 d y=\int\left(\frac{1}{x}+1\right) d x \\& \frac{y^6}{6}=\log x+x+c\end{aligned}[/tex]

We are given the initial condition as y(1) = 3.

Substitute x=1 and y=3, we get the following:

[tex]\begin{aligned}\frac{3^6}{6} & =\log 1+1+c \\c & =\frac{3^5}{2}-1 \\c & =\frac{243-2}{2}=\frac{241}{2}\end{aligned}[/tex]

Substitute c=241/2 in the equation [tex]\frac{y^6}{6}=\log x+x+c[/tex], we get the following:

[tex]\begin{aligned}& \frac{y^6}{6}=\log (x)+x+\frac{241}{2} \\& y^6=6 \log (x)+6 x+3(241) \\& y^6=6 \log x+6 x+723\end{aligned}[/tex]
