To solve the initial value problem [tex](IVP) \(y' = \lambda y\), \(y(0) = 0\),[/tex] where [tex]\(\lambda = 1.1\)[/tex], we can use separation of variables.

1.1 Two explicit solutions of the IVP:

Let's solve the differential equation [tex]\(y' = \lambda y\)[/tex] first. We separate the variables and integrate:

[tex]\(\frac{dy}{y} = \lambda dx\)[/tex]

Integrating both sides:

[tex]\(\ln|y| = \lambda x + C_1\)[/tex]

Taking the exponential of both sides:

[tex]\(|y| = e^{\lambda x + C_1}\)[/tex]

Since, [tex]\(y(0) = 0\)[/tex] we have [tex]\(|0| = e^{0 + C_1}\)[/tex], which implies [tex]\(C_1 = 0\).[/tex]

Thus, the general solution is:

[tex]\(y = \pm e^{\lambda x}\)[/tex]

Substituting [tex]\(\lambda = 1.1\)[/tex], we have two explicit solutions:

[tex]\(y_1 = e^{1.1x}\) and \(y_2 = -e^{1.1x}\)[/tex]

1.2 Existence and uniqueness analysis:

To analyze the existence and uniqueness of the IVP on the open rectangle [tex]\(R = (-5,2) \times (-1,3)\)[/tex], we need to check if the function [tex]\(f(x,y) = \lambda y\)[/tex] satisfies the Lipschitz condition on this rectangle.

The partial derivative of [tex]\(f(x,y)\)[/tex] with respect to [tex]\(y\) is \(\frac{\partial f}{\partial y} = \lambda\),[/tex] which is continuous on [tex]\(R\)[/tex]. Since \(\lambda = 1.1\) is a constant, it is bounded on [tex]\(R\)[/tex] as well.

Therefore, [tex]\(f(x,y) = \lambda y\)[/tex] satisfies the Lipschitz condition on [tex]\(R\),[/tex] and by the Existence and Uniqueness Theorem, there exists a unique solution to the IVP on the interval [tex]\((-5,2)\)[/tex] that satisfies the initial condition [tex]\(y(0) = 0\).[/tex]

This analysis agrees with the solutions we obtained in question 1.1, where we found two explicit solutions [tex]\(y_1 = e^{1.1x}\)[/tex] and [tex]\(y_2 = -e^{1.1x}\)[/tex]. These solutions are unique and exist on the interval [tex]\((-5,2)\)[/tex] based on the existence and uniqueness analysis. Additionally, when [tex]\(x = 0\),[/tex] both solutions satisfy the initial condition [tex]\(y(0) = 0\).[/tex]

Oppositely charged objects do indeed attract each other, and this attraction is responsible for holding atoms together in many compounds. However, Ernest Rutherford's model of the atom, known as the planetary model, failed to explain why electrons were not pulled into the atomic nucleus by this attractive force.

Rutherford's planetary model proposed that electrons orbited the nucleus much like planets orbiting the sun, held in place by the electrostatic attraction between the positively charged nucleus and negatively charged electrons.

According to classical physics, accelerating charged particles should emit electromagnetic radiation and lose energy, ultimately causing them to spiral into the nucleus. This phenomenon is known as the "radiation problem."

To address this issue, a new understanding of atomic structure emerged with the development of quantum mechanics. Quantum mechanics introduced the concept of energy levels and quantized electron orbits.

Electrons are now described as existing in specific energy levels or electron shells, where they have stable orbits without continuously emitting radiation. These energy levels and their corresponding electron configurations determine the chemical properties of elements and the formation of chemical bonds.

In summary, while oppositely charged objects do attract each other, Rutherford's model failed to explain why electrons did not collapse into the nucleus.

The development of quantum mechanics provided a more accurate understanding of the atomic structure, introducing the concept of quantized energy levels and stable electron orbits that prevent the collapse of electrons into the nucleus.

I, II, and III only are the correct options for statements about the coefficient of variation (CV).

Coefficient of variation (CV) is a measure of the degree of variation of a set of data points relative to the mean of the same data points. It is calculated as the ratio of the standard deviation of a data set to its mean, and then multiplied by 100% to get the percentage value. The CV is used to compare the variation of the risks of two or more assets that have different expected returns.

Therefore, it is particularly useful when dealing with datasets that have varying means, such as in finance. A lower CV implies that the data points in the dataset are closely clustered around the mean, while a higher CV implies that the data points are widely spread out from the mean. Thus, the higher the CV, the higher the risk, and the lower the CV, the lower the risk. Therefore, the correct option is I, II, and III only.

The positive value of producer surplus indicates that the producers are willing to sell the good at the given price of $26, and they are making $16 from the sale of the good.

a) The given demand function and supply function are:

P = -QD2 – 2QD + 64 and P = QS2 – 2QS + 14 respectively. When assuming pure competition, the equilibrium price can be found by equating the demand function and supply function to each other. Equating,

-QD2 – 2QD + 64 = QS2 – 2QS + 14.

QD2 + 2QD + QS2 – 2QS = 50.

QD2 + 2QD + QS2 – 2QS – 50 = 0.

Now we can solve for equilibrium quantity:

QS2 + QD2 = 50 – 2(QD – QS)

2.QS2 + QD2 = 50.

Now solving further, QS = 4 and QD = 6.

Now, substituting these equilibrium values into the demand function and supply function, we can calculate the equilibrium price:

P = -QD2 – 2QD + 64 = -6(6) – 2(6) + 64 = 26.P = QS2 – 2QS + 14 = 4(4) – 2(4) + 14 = 18.

As a result, consumer surplus is:

CS = 1/2 (6-26) (6) = $-60

Producer surplus is:

PS = 1/2 (26-18) (4) = $16

b) Consumer surplus is defined as the benefit received by the consumers from purchasing a good at a price lower than what they are willing to pay. It measures the difference between the actual price paid by the consumers and the maximum price they are willing to pay for a good. In this case, the negative value of consumer surplus indicates that the consumers are not willing to pay the given price of $26. They are losing $60 to purchase the good.Producer surplus is the difference between the price at which a producer sells a good and the minimum price that the producer is willing to accept for the good. In this case, the positive value of producer surplus indicates that the producers are willing to sell the good at the given price of $26, and they are making $16 from the sale of the good.

The complex number 6 + 6√3i can be converted to polar form as r(cosθ + isinθ), where r is the magnitude of the complex number and θ is the argument or angle.

1. To convert the complex number 6 + 6√3i to polar form, we first calculate the magnitude or modulus (r) using the formula r = √(a² + b²), where a = 6 and b = 6√3. So, r = √(6² + (6√3)²) = 12. Then, we determine the argument (θ) using the formula θ = tan⁻¹(b/a), where a = 6 and b = 6√3. So, θ = tan⁻¹((6√3)/6) = π/3. Therefore, the polar form of the complex number is 12(cos(π/3) + isin(π/3)).

Part 1:

SNT represents the intersection of sets S and T, i.e., the numbers that are divisible by both 3 and 4. To find SNT, we need to identify the common multiples of 3 and 4 within the range from 1 to 1000. Since the least common multiple of 3 and 4 is 12, we can determine SNT by finding all the multiples of 12 within the given range.

The multiples of 12 from 1 to 1000 are 12, 24, 36, 48, ..., 996. So, SNT = {12, 24, 36, 48, ..., 996}.

The cardinality of SNT, denoted as |SNT|, represents the number of elements in the set SNT. In this case, |SNT| is the count of multiples of 12 within the range from 1 to 1000.

To calculate |SNT|, we can use the formula for the count of multiples:

|SNT| = (last multiple - first multiple) / common difference + 1

In this case, the first multiple is 12, the last multiple is 996, and the common difference is 12.

|SNT| = (996 - 12) / 12 + 1 = 83

Therefore, |SNT| = 83.

Part 2:

SUT represents the union of sets S and T, i.e., the numbers that are divisible by either 3 or 4 or both. To find SUT, we need to identify all the numbers in the range from 1 to 1000 that are divisible by 3 or 4.

To calculate SUT, we can merge the elements of sets S and T, ensuring that there are no duplicates. We can start by listing the multiples of 3 and then add the multiples of 4, excluding the common multiples already accounted for in S.

Multiples of 3: 3, 6, 9, ..., 999

Multiples of 4: 4, 8, 12, ..., 996

Combining these lists, we have:

SUT = {3, 4, 6, 8, 9, 12, ..., 996, 999}

To determine |SUT|, we count the number of elements in the set SUT. In this case, we have to consider all the multiples of 3 and 4 up to 1000.

To calculate |SUT|, we count the multiples of 3 and 4 separately and subtract the count of common multiples (multiples of 12) to avoid double counting.

Multiples of 3: 3, 6, 9, ..., 999

Count of multiples of 3 = (last multiple - first multiple) / common difference + 1 = (999 - 3) / 3 + 1 = 333

Multiples of 4: 4, 8, 12, ..., 996

Count of multiples of 4 = (last multiple - first multiple) / common difference + 1 = (996 - 4) / 4 + 1 = 249

Count of common multiples (multiples of 12): |SNT| = 83

|SUT| = Count of multiples of 3 + Count of multiples of 4 - Count of common multiples

      = 333 + 249 - 83

      = 499

Therefore, |SUT| = 499.

For the first system:

7x + 7y - z = 0

2x + 5z = 0

3x + 3y = 0

We can write the system in matrix form as AX = B, where A is the coefficient matrix, X is the variable matrix, and B is the constant matrix.

Calculating the inverse of matrix A, we find:

A⁻¹ = [tex]\left[\begin{array}{ccc}1/3\\0\\-1/3\end{array}\right][/tex]

Multiplying A⁻¹ by B, we get:

The dispersion of the position of the electron in this state < (r- )² > is 27ao²/10.

a) The normalization constant A:

Normalization is the process of ensuring that the wave function squared is equal to one over all space.

The square of the wave function defines the probability density of finding the particle at a given location.

The wave function R(E) = A2 exp(-r/3),

So, ∫|R(E)|² dv = 1

where dv = r² sin θ dr dθ dφ is the volume element.

(Here, θ and φ are the usual spherical coordinates.)

Now, using the above wave function,

∫|R(E)|² dv = ∫0∞ r² exp(-2r/3) dr ∫0π sin θ dθ ∫0²π dφ

= 4πA² ∫0∞ r² exp(-2r/3) dr= 4πA² [(-9/4)(exp(-2r/3)) {0,∞}]

= 4πA² [9/4]

= A² ∫0∞ r² exp(-2r/3)

dr= (3/2)A² ∫0∞ (2/3)r² exp(-2r/3) (3/2)

dr= (3/2)A² Γ(5/2)(2/3)³

= A² [3(4/3) (2/3)³ π^(1/2)/2]

= A² π^(1/2) [(2/3)^(5/2)]

= A² (2/3) π^(1/2)

The factor of r² in the integrand produces an extra factor of the radius cubed in the volume element, which is why we get a factor of 4πA² instead of just A².

Thus, normalization implies, 4πA² (2/3) π^(1/2) = 1,

A = (3/2π)^(1/4) (2/3)^(1/2).

b) The most probable distance of an electron from the nucleus:

The most probable distance of an electron from the nucleus is the radius of the maximum of the probability density function |R(E)|².

So, |R(E)|²= A² exp(-2r/3) r⁴.

The derivative of |R(E)|² with respect to r is,

(d/dr) |R(E)|² = A² exp(-2r/3) r² (2r/3-5)

Therefore, the maximum of the probability density function occurs at r = 5/2 (ao) (which is the most probable distance of an electron from the nucleus).

c) The average distance of an electron from the nucleus:

The average distance of an electron from the nucleus is given by, ⟨r⟩

= ∫|R(E)|² r dv / ∫|R(E)|² dv.⟨r⟩

= ∫0∞ r³ exp(-2r/3) dr / ∫0∞ r² exp(-2r/3) dr

Substituting x = 2r/3, dx = 2/3 dr in the numerator gives,⟨r⟩

= (3/2) ∫0∞ (2/3 x)^(3/2) exp(-x) dx / ∫0∞ (2/3 x)^(1/2) exp(-x)

dx= (3/2) ∫0∞ x^(3/2) exp(-x)

dx / ∫0∞ x^(1/2) exp(-x)

dx= (3/2) Γ(5/2) / Γ(3/2)

= (3/2)(3/2)(1/2) Γ(1/2) / Γ(3/2)

= 3/4 (π/2) / (3/4) π^(1/2)

= 2ao/3.

d) The dispersion of the position of the electron in this state < (r- )² >:

The variance of the position, (Δr)² = < (r- ⟨r⟩)² >,< (r- ⟨r⟩)² >

= ∫|R(E)|² (r- ⟨r⟩)² dv / ∫|R(E)|²

dv= ∫0∞ r² exp(-2r/3) (r- ⟨r⟩)² dr / ∫0∞ r² exp(-2r/3) dr

Again, substituting x = 2r/3, dx = 2/3 dr in the numerator gives,< (r- ⟨r⟩)² >

= (3/2)² ∫0∞ (2/3 x)² (x - 2ao/3)² (2/3)² x exp(-x) dx / ∫0∞ (2/3 x)² exp(-x)

dx= (9/4) ∫0∞ x^4 exp(-2x/3) dx / ∫0∞ x² exp(-2x/3) dx

Substituting y = 2x/3, dy = 2/3 dx in both the numerator and denominator,< (r- ⟨r⟩)² >

= (9/4) (3/2)² ∫0∞ y^4 exp(-y) dy / ∫0∞ y² exp(-y) dy

= 27/4 ∫0∞ y^4 exp(-y) dy / ∫0∞ y² exp(-y) dy

= 27/4 Γ(5) / Γ(3)= 27/4 (4!)/(2!)²

= (27ao²)/10.

The measure of the central angle POQ is 2π/3 radians.

To find the measure of the central angle POQ in radians, we can use the formula:

θ = s/r,

where θ is the angle in radians, s is the arc length, and r is the radius.

Given that the arc length PQ measures 6π inches and the radius OQ measures 9 inches, we can substitute these values into the formula:

θ = (6π) / 9

Now, simplify the expression:

θ = 2π / 3

To understand this, consider that the circumference of a circle is given by the formula C = 2πr. In this case, the arc PQ measures 6π inches, which is one-third of the total circumference of the circle (since it's measured in radians). The central angle POQ is formed by this arc and the radius OQ, creating a sector of the circle. As the arc PQ measures one-third of the circumference, the angle POQ also covers one-third of the full circle, resulting in 2π/3 radians.

The percentage decrease in latency once 5G is available is approximately 97.96%, rounded to the nearest tenth of a percent.

To calculate the percentage decrease in latency, we can use the following formula:

Percentage Decrease = (Initial Latency - New Latency) / Initial Latency × 100

In this case, the initial latency of the 4G network is 49 ms, and the new latency requirement for 5G is 1 ms. We can substitute these values into the formula:

Percentage Decrease = (49 ms - 1 ms) / 49 ms × 100

Simplifying this equation, we have:

Percentage Decrease = 48 ms / 49 ms × 100

To calculate the area under the standard normal curve to the right of z = -2.3, we need to find the probability that a standard normal random variable Z is greater than -2.3. This can be done by converting -2.3 to a z-score and finding the area under the standard normal curve to the right of this z-score.We can use a standard normal distribution table to find the area to the left of z = -2.3, which is 0.0107. To find the area to the right of z = -2.3, we subtract this value from 1.P(Z > -2.3) = 1 - P(Z < -2.3) = 1 - 0.0107 = 0.9893

Therefore, the area under the standard normal curve to the right of z = -2.3 is 0.9893. This means that the probability of getting a z-score greater than -2.3 is 0.9893 or 98.93%. This can be interpreted as the percentage of values that lie to the right of -2.3 on a standard normal distribution curve.This result can be useful in many statistical applications.

To solve the given wave equation using the D'Alembert solution, we first need to determine the wave speed. From the given equation, we have Ut^2 = 25Uxx, which implies that the wave speed is 5.

The D'Alembert solution for the wave equation is given by:

u(x,t) = 1/2[f(x+ct) + f(x-ct)] + 1/(2c) * ∫[x-ct, x+ct] g(s) ds,

where f(x) represents the initial position of the string and g(s) represents the initial velocity.

In this case, we have f(x) = x(7 - x) and g(x) = 0.

Substituting these values into the D'Alembert solution, we have:

u(x,t) = 1/2[(x+ct)(7-(x+ct)) + (x-ct)(7-(x-ct))].

Now, let's evaluate the specific values requested:

  u(1, 100) = 1/2[(1+100)(7-(1+100)) + (1-100)(7-(1-100))].

  Evaluating the expression gives u(1, 100) = 359994.

3. u(0.5, 10):

  Substituting x = 0.5 and t = 10 into the equation, we have:

  u(0.5, 10) = 1/2[(0.5+10)(7-(0.5+10)) + (0.5-10)(7-(0.5-10))].

  Evaluating the expression gives u(0.5, 10) ≈ 3596.75.

4. u(3.5, 10):

  Substituting x = 3.5 and t = 10 into the equation, we have:

  u(3.5, 10) = 1/2[(3.5+10)(7-(3.5+10)) + (3.5-10)(7-(3.5-10))].

To evaluate the integral ∬ fex dxdy, we need to determine the limits of integration and then perform the integration.

Regarding the second question, to find the volume of the solid bounded by the surface z = 1 - x² - y² and the xy-plane, we need to set up a triple integral over the region that the surface bounds. In this case, the surface is a downward-facing paraboloid opening towards the z-axis.

Let's denote the region bounded by the surface as D. To find the volume, we can set up the triple integral using the following equation:

V = ∭D dV

Here, dV represents the volume element.

The limits of integration for the triple integral will be determined by the boundaries of the region D. Since the surface z = 1 - x² - y² is symmetric about the x and y axes, we can integrate over a single quadrant and then multiply the result by 4 to account for the other quadrants.

Let's assume we integrate over the first quadrant where x ≥ 0 and y ≥ 0. The limits of integration for x and y will be determined by the boundary of the region D in the first quadrant.

Since the surface is z = 1 - x² - y², we need to find the values of x and y where z = 0 (the xy-plane) intersects the surface.

Setting z = 0 in the equation, we have:

0 = 1 - x² - y²

Rearranging the equation, we get:

x² + y² = 1

This represents the equation of a circle centered at the origin with a radius of 1.

In polar coordinates, the limits for the integration of x and y will be:

0 ≤ r ≤ 1

0 ≤ θ ≤ π/2

Therefore, the triple integral to find the volume will be:

V = 4 * ∬D dz dy dx

V = 4 * ∫[0,π/2]∫[0,1]∫[0,√(1-x²-y²)] dz dy dx

Evaluating this triple integral will give us the volume of the solid bounded by the surface z = 1 - x² - y² and the xy-plane.

The problem states that there are four complex numbers, Z₁, Z₂, Z₃, and Z₄, represented as points on the complex plane. It asks to show that the triangles formed by ZᵢZ₂ and DOZ₃₁ are similar to the triangle

To show that the triangles are similar, we need to demonstrate that their corresponding angles are equal and their sides are proportional.

1. Angle Equality:

  - Triangle ZᵢZ₂ and triangle DOZ₃₁: The angle between ZᵢZ₂ and DOZ₃₁ at Z₂ is the same as the angle between Z and AOZ₁ at Z.

  - Triangle ZᵢZ₂ and triangle DOZ₃₁: The angle between ZᵢZ₂ and DOZ₃₁ at Zᵢ is the same as the angle between Z and AOZ₁ at Z₁.

2. Side Proportions:

  - Triangle ZᵢZ₂ and triangle DOZ₃₁: The ratio of the lengths ZᵢZ₂ to DOZ₃₁ is the same as the ratio of the lengths Z to AOZ₁.

By proving angle equality and side proportionality for both triangles, we can conclude that ZᵢZ₂ and DOZ₃₁ are similar to AOZ₁. This similarity can be understood geometrically as the triangles having corresponding angles and proportional sides, indicating their similarity in shape and structure.

(a) Continuity of f at x=0 is to be determined.  

Definition: A function is said to be continuous at a point c in its domain if its limit at that point exists and is equal to the value of the function at that point.  

Let's evaluate the limit of f(x) as x approaches 0 from the right side:

limf(x) as x → 0+ = limsinc(x) as x → 0+

= lim sin(x) / x as x → 0+

= 1.  

Now, let's evaluate the limit of f(x) as x approaches 0 from the left side:

limf(x) as x → 0-

= limsinc(x) as x → 0-

= lim sin(x) / x as x → 0-

= 1.  

Since the limits of f(x) as x approaches 0 from both sides exist and are equal to f(0), therefore f is continuous at x=0.  

Answer: Yes, f is continuous at x=0.

(b) Differentiability of f at x=0 is to be determined.  

Definition: A function is said to be differentiable at a point c in its domain if its limit at that point exists and is finite.

 Let's evaluate the limit of f'(x) as x approaches 0:

[tex]limf'(x) as x → 0 = lim (d/dx[sinc(x)]) as x → 0[/tex]

= limcos(x)/x - sin(x)/(x^2) as x → 0

= 0 - 1/0^2 = -∞.  

Since the limit of f'(x) as x approaches 0 is not finite, therefore f is not differentiable at x=0.

 Answer: No, f is not differentiable at x=0.

[tex]limcos(x)/x - sin(x)/(x^2) as x → 0[/tex]

(c) Roots of f are to be determined.  

Definition: A root of a function is any point c in its domain at which f(c)=0.

 f(x)=sinc(x)=sin(x)/x=0 when sin(x)=0.  sin(x)=0 for x=nπ

where n is an integer.

Therefore, f has roots at x=nπ,

where n is an integer.

Each root has a multiplicity of 1 because the derivative of sinc(x) is never equal to 0.

Answer: f has roots at x=nπ,

where n is an integer, and each root has a multiplicity of 1.

(d) The supremum and maximum of f and the number of relative extrema are to be determined.

Definition: The supremum of a function f is the least upper bound of the range of f.

The maximum of a function f is the largest value of f on its domain.

The range of f is [-1,1].  

Therefore, sup f=1 and max f=1.  

The function sinc(x) is continuous, symmetric about the y-axis, and has zeros at the odd multiples of π.  

The relative maxima occur at the even multiples of π, and the relative minima occur at the odd multiples of π.  

The value of the function at each relative extremum is -1.  

Let c be an even integer, so that x=cπ is a relative extremum.

Then f(cπ)=sinc(cπ)=(-1)^c/(cπ).

By the definition of absolute value,

[tex]f(cπ)|=|-1^c/(cπ)|=1/(cπ)=√(1/(c^2π^2))[/tex].  

Therefore, [tex]f(cπ)|=-1√(1+c^2π^2).[/tex]

Answer: sup f=1, max f=1, there are infinite relative extrema, and f(cπ)|=-1√(1+c^2π^2) for any even integer c.

(e) An infinite product is to be evaluated.

Formula:

p[tex]i(n=1 to ∞) (1+(z/n))^-1[/tex] =[tex]e^(γz)/z pi(n=1 to ∞) (1+(n^2/a^2))^-1[/tex]

= [tex]a/π pi(n=1 to ∞) (1+(na)^-2[/tex])  = a/π sin(πa).  

Let a=1/√2 and z=1.  

Then,

11 1 1 1 11 1 1 11 + + 22 2 2 2 2 2 22  = [tex](1+(1/1))^-1(1+(1/2))^-1(1+(1/3))^-1(1+(1/4))^-1[/tex]...  = 1/(1+1/2) * 2/(2+1/3) * 3/(3+1/4) * 4/(4+1/5)...  

= 2/3 * 3/4 * 4/5 * 5/6 *...  

= [3/(2+1)] * [4/(3+1)] * [5/(4+1)] * [6/(5+1)] *...

= [3/2 * 4/3 * 5/4 * 6/5 *...] / [1+1/2+1/3+1/4+...]  

= 3/2 * πsin(π/2) / [tex]e^γ[/tex]

the correct answers are:

(a) x = (1, -2) is not an eigenvector.

(b) x = (1, 2) is an eigenvector.

(c) x = (2, 1) is an eigenvector.

(d) x = (-1, 0) is not an eigenvector.

To determine whether a given vector x is an eigenvector of matrix A, we need to check if there exists a scalar λ (called eigenvalue) such that Ax = λx.

Let's evaluate each case:

(a) x = (1, -2)

To check if x = (1, -2) is an eigenvector, we compute Ax:

A * x = [[6, 2], [2, 3]] * [1, -2]

      = [6 * 1 + 2 * (-2), 2 * 1 + 3 * (-2)]

      = [6 - 4, 2 - 6]

      = [2, -4]

Since Ax = [2, -4] is not a scalar multiple of x = [1, -2], x is not an eigenvector.

(b) x = (1, 2)

Again, we compute Ax:

A * x = [[6, 2], [2, 3]] * [1, 2]

      = [6 * 1 + 2 * 2, 2 * 1 + 3 * 2]

      = [6 + 4, 2 + 6]

      = [10, 8]

Since Ax = [10, 8] is a scalar multiple of x = [1, 2] (10/1 = 10, 8/2 = 4), x is an eigenvector.

(c) x = (2, 1)

Once again, compute Ax:

A * x = [[6, 2], [2, 3]] * [2, 1]

      = [6 * 2 + 2 * 1, 2 * 2 + 3 * 1]

      = [12 + 2, 4 + 3]

      = [14, 7]

Since Ax = [14, 7] is a scalar multiple of x = [2, 1] (14/2 = 7, 7/1 = 7), x is an eigenvector.

(d) x = (-1, 0)

Compute Ax:

A * x = [[6, 2], [2, 3]] * [-1, 0]

      = [6 * (-1) + 2 * 0, 2 * (-1) + 3 * 0]

      = [-6, -2]

Since Ax = [-6, -2] is not a scalar multiple of x = [-1, 0], x is not an eigenvector.

Based on these calculations, the correct answers are:

(a) x = (1, -2) is not an eigenvector.

(b) x = (1, 2) is an eigenvector.

(c) x = (2, 1) is an eigenvector.

(d) x = (-1, 0) is not an eigenvector.

The area of the surface generated by rotating the curve x = √(a^2 - y^2) about the y-axis is 2π a^2.

To find the area of the surface generated by rotating the given curve x = √(a^2 - y^2), where 0 < y < a, about the y-axis, we can use the formula for the surface area of a solid of revolution.

The surface area formula for rotating a curve about the y-axis is given by:

A = 2π ∫[a, b] x(y) √(1 + (dx/dy)^2) dy,

where x(y) represents the equation of the curve and dx/dy is the derivative of x with respect to y.

In this case, the equation of the curve is x = √(a^2 - y^2). Taking the derivative of x with respect to y, we have dx/dy = -y/√(a^2 - y^2).

Substituting these values into the surface area formula, we get:

A = 2π ∫[0, a] √(a^2 - y^2) √(1 + (y^2/(a^2 - y^2))) dy.

Simplifying the expression under the square root, we have:

A = 2π ∫[0, a] √(a^2 - y^2) √(a^2/(a^2 - y^2)) dy.

Canceling out the common terms, we get:

A = 2π ∫[0, a] a dy.

Integrating with respect to y, we have:

A = 2π a[y] evaluated from 0 to a.

The singular points of the given differential equation are 0 and 1/3. The singularity is irregular.

Given differential equation is x(3x)²y" + (x + 1)y' - 2y = 0.

To find the singular points of the given differential equation, we will use the following formula:

x²p(x) = A(x)y'' + B(x)y' + C(x)y

Here, p(x) = 3x, A(x) = x³, B(x) = x + 1 and C(x) = -2

Now, x²p(x) = x².3x = 3x³, A(x) = x³

Therefore, we can write the given differential equation as:

3x³y'' + (x + 1)y' - 2y = 0

On comparing the coefficients with the general form of the Euler-Cauchy equation (A(x)y'' + B(x)y' + C(x)y = 0), we have p1 = 0, p2 = 1/3, therefore, the singular points are x = 0 and x = 1/3.

To find whether the singularity is regular or irregular, we use the following formula:

q(x) = p(x)[p(x)-1]A(x)B(x)

Let's calculate the value of q(x) for x = 0:

q(0) = 3x²(x²p(x)-1)A(x)B(x)

Substitute the given values in the above formula to get

q(0) = 0

Here, q(0) = 0. Therefore, the singularity at x = 0 is regular.

For x = 1/3: q(1/3) = 3x²(x²p(x)-1)A(x)B(x)

Substitute the given values in the above formula to get

q(1/3) = -16/27

Here, q(1/3) ≠ 0. Therefore, the singularity at x = 1/3 is irregular.

Thus, the singular points of the given differential equation are 0 and 1/3. The singularity at x = 0 is regular, while the singularity at x = 1/3 is irregular.

To build the wall in 10 days, we would need 40 workers.

To solve this problem, we can use the concept of man-days, which represents the total amount of work done by a worker in a day. Let's denote the number of workers needed to build the wall in 10 days as N.

Given that 16 workers can build the wall in 25 days, we can calculate the total man-days required to build the wall using the formula:

Total man-days = Number of workers × Number of days

For the first case, with 16 workers and 25 days:

Total man-days = 16 workers × 25 days = 400 man-days

Now, let's consider the second case, where we need to determine the number of workers required to build the wall in 10 days:

Total man-days = N workers × 10 days

Since the amount of work to be done (total man-days) remains the same, we can equate the two equations:

400 man-days = N workers × 10 days

To find the value of N, we rearrange the equation:

N workers = 400 man-days / 10 days

N workers = 40 workers

Therefore, to build the wall in 10 days, we would need 40 workers.

The position vector for the particle is:

r(t) = ((1/2)t^3, -4sin(t), -(1/25)cos(5t)) + (0, 4t, t/5) + (-4, -2, 0)

To find the position vector, we need to integrate the given acceleration function twice.

Given:

a(t) = (3t, 4sin(t), cos(5t))

v(0) = (0, 0, 5)

r(0) = (-4, -2, 0)

First, let's find the velocity function v(t) by integrating a(t):

v(t) = ∫(a(t)) dt = ∫(3t, 4sin(t), cos(5t)) dt

= (3/2)t^2, -4cos(t), (1/5)sin(5t) + C1

Using the initial velocity condition v(0) = (0, 0, 5):

(0, 0, 5) = (3/2)(0)^2, -4cos(0), (1/5)sin(5(0)) + C1

C1 = (0, 4, 1/5)

Next, let's find the position function r(t) by integrating v(t):

r(t) = ∫(v(t)) dt = ∫((3/2)t^2, -4cos(t), (1/5)sin(5t) + C1) dt

= (1/2)t^3, -4sin(t), -(1/25)cos(5t) + C1t + C2

Using the initial position condition r(0) = (-4, -2, 0):

(-4, -2, 0) = (1/2)(0)^3, -4sin(0), -(1/25)cos(5(0)) + C1(0) + C2

C2 = (-4, -2, 0)

Finally, substituting the values of C1 and C2 into the position function, we get:

r(t) = (1/2)t^3, -4sin(t), -(1/25)cos(5t) + (0, 4, 1/5)t + (-4, -2, 0)

Therefore, the position vector for the particle is:

The solution of the given equation is calculated as `-2 + i`.Given: `cosh(z) + 2 sinh(z) = -2i`. We know that `cosh² (z) - sinh² (z) = 1`

Substituting the value of cosh(z) and sinh(z) we get:

x²  - y²  = 1

⇒ x²  = y²  + 1

We are given the equation: `cosh(z) + 2 sinh(z) = -2i`

Substituting the values of cosh(z) and sinh(z) we get:

x + 2y = -2i

⇒ x = -2y - 2i

Using the value of x in the equation obtained from

cosh² (z) - sinh² (z) = 1,

we get:`(-2y - 2i)^2 = y^2 + 1`

⇒ `4y²  + 8iy - 3 = 0`

Solving the quadratic equation we get: `

y = 1/2 + √(2)/2 i

and y = 1/2 - √(2)/2 i`

Using these values we get:

x = -2y - 2i

= -1 - √(2) i

and x = -1 + √(2) i

Therefore, the solutions are:`

z = ln[-1 + √(2) i + √(3)]] + 2nπi` and

`z = ln[-1 - √(2) i + √(3)]] + 2nπi`

Where `n` is any integer.

∴ `i² = -1`

Now, `i¹+2i` = `i(1 + 2i)`

= `-2 + i`

Thus, the solution is `-2 + i`.

f(x + h) = 3(x + h) - 4 = 3x + 3h - 4
(B) f(x + h) - f(x):
Substituting f(x + h) and f(x) into the expression, we get:
f(x + h) - f(x) = (3x + 3h - 4) - (3x - 4) = 3h
(C) (f(x + h) - f(x))/h:
Substituting the expressions from parts (A) and (B) into the expression, we have:
(f(x + h) - f(x))/h = (3h)/h = 3

Therefore, (A) f(x + h) simplifies to 3x + 3h - 4, (B) f(x + h) - f(x) simplifies to 3h, and (C) (f(x + h) - f(x))/h simplifies to 3.

Therefore, the Laplace transform of √cos(2√t) is F(s) = s / (s²+ 4t).

To find the Laplace transform of √cos(2√t), we can use the properties of Laplace transforms and the known transforms of elementary functions.

Let's denote the Laplace transform of √cos(2√t) as F(s). We'll apply the property of the Laplace transform for a time shift, which states that:

Lf(t-a) = [tex]e^{(-as)[/tex] * F(s)

In this case, we have a time shift of √t, so we can rewrite the function as:

√cos(2√t) = cos(2√t - π/2)

Using the Laplace transform of cos(at), which is s / (s² + a²), we can express the Laplace transform of √cos(2√t) as:

F(s) = Lcos(2√t - π/2) = Lcos(2√t) = s / (s² + (2√t)²) = s / (s² + 4t)

So, the Laplace transform of √cos(2√t) is F(s) = s / (s² + 4t).
