using the taylor remainder estimation theorem, what is the maximum possible error of using the first three nonzero terms from the maclaurin series for cos x to approximate cos 2?

The required answer is , the given series converges to cos h(31), which is approximately equal to 1.0686 x 10^13

To determine the value to which the series converges, we can use the Maclaurin series. The Maclaurin series is a special case of the Taylor series, where the center point is 0. It allows us to represent a function as an infinite sum of powers of x, multiplied by coefficients derived from the function's derivatives evaluated at the center point.
Determine the value the series converges to Since the series converges to the cosine function, we can determine the value the series converges
In this case, we have the series (31) 2n (-1)" (2n)! n=0. To find the Maclaurin series for this function, we first need to recognize that it is the series for cos h(x), which is defined as:
cos h(x) = (e^ x + e^(-x))/2
The given series expansion  of the function and we notice that the given series match of the Maclaurin series. The Maclaurin series expansion of the cosine function.
Using the Maclaurin series for e ^x and e^(-x), we can write:
cos h(x) = (1 + x^2/2! + x^4/4! + x^6/6! +...) + (1 - x^2/2! + x^4/4! - x^6/6! +...))/2

Simplifying this expression, we get:
cos h(x) = 1 + x^2/2! + x^4/4! + x^6/6! +...

Therefore, the given series converges to cos h(31), which is approximately equal to 1.0686 x 10^13

If an investigator reports that main effects exist for both factors, it implies nothing whatsoever about the presence or absence of an interaction.

The presence of main effects for both factors indicates that each factor individually has a significant impact on the outcome variable. A main effect refers to the effect of a single independent variable while ignoring the other independent variables.

However, the presence of main effects does not provide any information about how the factors interact with each other.

An interaction occurs when the effect of one independent variable on the outcome variable depends on the level of another independent variable.

In other words, the combined effect of the factors is different from the sum of their individual effects.

To determine if an interaction is present, it is necessary to analyze the data and specifically test for the interaction effect.

This can be done through various statistical techniques, such as conducting an analysis of variance (ANOVA) with interaction terms or fitting a regression model with interaction terms and examining their significance.

Therefore, reporting main effects for both factors does not imply anything about the presence or absence of an interaction. Additional analysis and testing are required to draw conclusions about the existence of an interaction effect.

For a binomial distribution involving 3000 marriages with a probability of 0.45 for divorce within 10 years, the mean is 1350 and the standard deviation is approximately 25.12.

To calculate the mean and standard deviation for a binomial distribution involving 3000 marriages and a divorce probability of 0.45 within 10 years, we use the formulas:

The mean (μ) is found by multiplying the number of trials (n) by the probability of success (p), giving μ = 3000 * 0.45 = 1350.

The standard deviation (σ) is calculated using the formula σ = sqrt(n * p * (1 - p)). Plugging in the values, we get σ = sqrt(3000 * 0.45 * (1 - 0.45)) ≈ 25.12.

The mean represents the expected number of marriages that will end in divorce within 10 years, which in this case is approximately 1350.

The standard deviation measures the spread or variability in the number of marriages that may end in divorce within 10 years, with a value of approximately 25.12.

Answer:

Step-by-step explanation:

The Blue Ridge Hot Tubs example involves Howie Jones, who is considering how much of two hot tub models to produce: Aqua-Spas and Hydro-Luxes.

The production of these hot tubs requires different amounts of labor and materials, and Howie has limited resources available for production. The goal is to determine the optimal production quantities that maximize Howie's profit.

a. If Howie Jones has to purchase a single piece of equipment for $1,000 in order to produce any Aqua-Spas or Hydro-Luxes, this will affect the formulation of the model of his decision problem in the following ways:

The fixed cost of production will increase by $1,000, since Howie has to purchase the equipment regardless of how many hot tubs he produces.

The cost per unit of production will decrease, since the fixed cost is now spread over a larger number of units produced. This means that the objective function (i.e., the profit) will change, and the optimal production quantities may also change.

The new formulation of the model will need to account for the additional fixed cost of the equipment purchase, and the optimal solution will need to be recalculated.

b. If Howie Jones must buy one piece of equipment that costs $900 in order to produce any Aqua-Spas and a different piece of equipment that costs $800 in order to produce any Hydro-Luxes, this will affect the formulation of the model for his problem in the following ways:

The fixed cost of production will increase by $1,700, since Howie has to purchase both pieces of equipment regardless of how many hot tubs he produces.

The cost per unit of production will still decrease, but the decrease will be different for each hot tub model.

This means that the objective function and the constraints will change, and the optimal production quantities may also change.

The new formulation of the model will need to account for the additional fixed costs of the equipment purchases, and the production constraints will need to reflect the fact that different equipment is required for each hot tub model.

The optimal solution will need to be recalculated to determine the optimal production quantities for each hot tub model, taking into account the cost of the equipment purchases.

So the equations for the normal line are: x = 4, y = 12.5 - (11/8)t, z = t.

First, we need to find the partial derivatives of the given surface:

f(x, y, z) = −7cos(πx) + 3x^2y + 2e^xz + 6yz

∂f/∂x = 7πsin(πx) + 6xye^xz

∂f/∂y = 3x^2 + 6z

∂f/∂z = 2xe^xz + 6y

Now, we can evaluate the partial derivatives at the given point P(4, 3, 0):

∂f/∂x(P) = 7πsin(4π) + 6(4)(3)e^0 = 0

∂f/∂y(P) = 3(4)^2 + 6(0) = 48

∂f/∂z(P) = 2(4)e^0 + 6(3) = 22

So the equation of the tangent plane is:

0(x - 4) + 48(y - 3) + 22(z - 0) = 0

Simplifying, we get:

8y + 11z = 132

This is the equation of the tangent plane using a coefficient of 8 for x.

To find the equation of the normal line, we need a vector normal to the tangent plane. The coefficients of the variables in the equation of the tangent plane give us the components of the normal vector, which is:

N = <0, 8, 11>

So a parametric equation for the normal line passing through P is:

x = 4 + 0t = 4

y = 3 + 8t

z = 0 + 11t

We can substitute x = 4 into the equation of the tangent plane to get:

8y + 11z = 100

Solving for y in terms of z, we get:

y = (100 - 11z)/8

Substituting this expression for y into the parametric equation for the normal line, we get:

x = 4

y = (100 - 11z)/8

z = t

Simplifying, we get:

x = 4

y = 12.5 - (11/8)t

Chords and tangents of a circleA chord of a circle is a line segment that joins any two points on the circle. It is important to note that a chord always stays inside the circle. Moreover, if a chord passes through the center of the circle, it is called a diameter. This is because it joins two points on the circle and passes through its center.A tangent to a circle is a line that touches the circle in exactly one point. Tangent lines are perpendicular to the radius of the circle at the point of contact. They are always outside the circle and never cross into the circle.

Note that the point of contact between the circle and the tangent line is called the point of tangency. The tangent line provides a flat surface or a platform for the circle to rest on and it also helps to support the circle.If you were to construct a tangent at a given point on a circle, you would first draw a radius of the circle through that point.

The set of voltages given by va = 180cos(377t) V, vb = 180cos(377t-120°) V, and vc = 180cos(377t-240°) V is a balanced three-phase set with a positive phase sequence.

The voltages given in this set are va = 180cos(377t) V, vb = 180cos(377t-120°) V, and vc = 180cos(377t-240°) V. To determine whether this set of voltages is balanced or not, we need to calculate the line-to-line voltages and compare them.

Line-to-line voltages are calculated by taking the difference between two phase voltages. For this set, the line-to-line voltages are as follows:

Vab = va - vb = 180cos(377t) - 180cos(377t-120°) = 311.13 sin(377t + 30°) V
Vbc = vb - vc = 180cos(377t-120°) - 180cos(377t-240°) = 311.13 sin(377t + 150°) V
Vca = vc - va = 180cos(377t-240°) - 180cos(377t) = 311.13 sin(377t - 90°) V

To check whether the set is balanced or not, we need to compare the magnitudes of these three line-to-line voltages. If they are equal, then the set is balanced, and if they are not equal, then the set is unbalanced.

In this case, we can see that the magnitudes of the three line-to-line voltages are equal to 311.13 V, which means that this set of voltages is balanced.

To determine the phase sequence, we can observe the time-varying components of the line-to-line voltages.

For this set, we can see that the time-varying components of the three line-to-line voltages are sin(377t + 30°), sin(377t + 150°), and sin(377t - 90°).

The phase sequence can be determined by observing the order in which these time-varying components appear.

If they appear in a positive sequence (i.e., 30°, 150°, -90°), then the phase sequence is positive, and if they appear in a negative sequence (i.e., 30°, -90°, 150°), then the phase sequence is negative.

In this case, we can see that the time-varying components of the three line-to-line voltages appear in a positive sequence, which means that the phase sequence is positive.

In conclusion, the set of voltages given by va = 180cos(377t) V, vb = 180cos(377t-120°) V, and vc = 180cos(377t-240°) V is a balanced three-phase set with a positive phase sequence.

The energy of a photon is given by the equation E = hf, where h is Planck's constant (6.626x10⁻³⁴ J·s) and f is the frequency of the light. Therefore, the energy of a photon with a frequency of 8.7x10¹⁴ Hz is:

E = hf = (6.626x10⁻³⁴ J·s)(8.7x10¹⁴ Hz) = 5.77x10⁻¹⁹ J

Now, the work function of the metal is 2.8 eV. We need to convert this to joules to be able to use it in our calculations. 1 eV is equal to 1.602x10⁻¹⁹ J. Therefore, the work function in joules is:

Φ = 2.8 eV × (1.602x10⁻¹⁹ J/eV) = 4.49x10⁻¹⁹ J

The maximum kinetic energy of the ejected photoelectron can be found by subtracting the work function from the energy of the incident photon:

KEmax = E - Φ = 5.77x10⁻¹⁹ J - 4.49x10⁻¹⁹ J = 2.41x10⁻¹⁹ J

The quotient rule can be proved by considering two functions, u(x) and v(x) such that their differential dy/dx = [v(x)du(x)/dx - u(x)dv(x)/dx] / [v(x)]^2.

Hence quotient rule is proved using differentials.

The derivative of a function y with respect to x:

dy/dx = lim(h->0) [f(x+h) - f(x)] / h

Now consider two functions, u(x) and v(x), and their ratio, y = u(x) / v(x).

Taking differentials of both sides:

dy = d(u/v)

Using quotient rule, we know that d(u/v) is:

d(u/v) = [v(x)du(x) - u(x)dv(x)] / [v(x)]^2

Substituting this into equation for dy:

dy = [v(x)du(x) - u(x)dv(x)] / [v(x)]^2

Dividing both sides by dx to get:

dy/dx = [v(x)du(x)/dx - u(x)dv(x)/dx] / [v(x)]^2

Next, we can substitute the definition of the derivative into this equation, giving:

dy/dx = lim(h->0) [v(x+h)du(x)/dx - u(x+h)dv(x)/dx] / [v(x+h)]^2

Now we can simplify the expression inside the limit by multiplying the numerator and denominator by v(x) + h*v'(x):

dy/dx = lim(h->0) [(v(x)+hv'(x))du(x)/dx - (u(x)+hu'(x))dv(x)/dx] / [v(x)+h*v'(x)]^2

Expanding the numerator and simplifying, we get:

dy/dx = lim(h->0) [(v(x)du(x)/dx - u(x)dv(x)/dx)/h + (v'(x)u(x) - u'(x)v(x))/[v(x)(v(x)+h*v'(x))]]

As h approaches zero, the first term in the numerator approaches the derivative of u/v, and the second term approaches zero. So we have:

dy/dx = [v(x)du(x)/dx - u(x)dv(x)/dx] / [v(x)]^2

which is the same as the expression we obtained using the quotient rule with differentials.

Therefore, we have proven the quotient rule using differentials.

To determine whether the series 1 + 12√2 + 13√3 + 14√4 + 15√5 + ... is convergent or divergent, we can use the comparison test.

Note that for n ≥ 2, we have: n√n > n√(n-1)

This is because n√n - (n-1)√(n-1) = n(√n - √(n-1)) > 0. Therefore, we can write: n√n > (n-1)√n

Multiplying both sides by n and simplifying, we get:

n^2√n > (n-1)n√n

n^2√n > n^2√(n-1)

Taking the square root of both sides, we get: n√n > √(n-1)n

Using this inequality, we can compare the given series to the series:

1 + 12√2 + 13√3 + 14√4 + 15√5 + ...

Every stage of the HRM process plays a critical role in achieving the organization's goals, and HRM managers must ensure that every stage is executed correctly.

Human Resource Management (HRM) is the process of selecting, hiring, training, developing, compensating, and evaluating employees in an organization. HRM is the backbone of an organization, as it is responsible for finding and keeping talented workers. The HRM process is an essential function for the success of an organization. Below are the stages in the HRM process:

Stage 1: Planning HRM process: The HRM process begins with the planning stage. In this stage, an organization decides how many workers they require, the kind of jobs to be filled, and the skills necessary for the job. The HRM process needs to analyze and predict future workforce needs to ensure there is a balanced workforce.

Stage 2: Recruiting: After the organization has developed a staffing plan, the next stage is to start recruiting and selecting candidates for the jobs. HRM managers should be able to attract the right candidates by promoting job postings, reviewing resumes, and conducting job interviews. The objective is to find the best person for the job.

Stage 3: Hiring: Once the recruitment process is over, HRM managers proceed to hire the best candidates. The hiring process must be done in a timely and efficient manner.

Stage 4: Developing and Training: Once hired, employees need to be trained and developed to perform their duties successfully. Employee development and training programs can help employees improve their knowledge and skills. It is essential to create a training program that aligns with the organization's goals.

Stage 5: Performance Appraisal: HRM managers must ensure that employees are performing well and meeting their targets. Regular performance appraisals help in identifying the areas that need improvement.

Stage 6: Compensation: HRM is responsible for determining the appropriate compensation packages for employees. The HRM process needs to provide equitable and fair compensation for employees.

When any part of the HRM process is neglected, it can lead to the organization's failure. For instance, if HRM managers fail to develop a staffing plan, the organization may not have the required workforce, leading to poor productivity. Similarly, if the recruitment process is not done correctly, it may lead to the hiring of the wrong employees. If there is no employee training program, employees may not have the necessary skills to perform their duties, leading to poor performance and decreased productivity.

When the HRM process works well, it can lead to increased productivity, employee satisfaction, and lower employee turnover. HRM managers can attract and retain talented employees, resulting in the organization's growth and success. A well-planned HRM process can align with the organization's goals, mission, and values, ensuring that employees are working towards the same objectives. In conclusion, the HRM process is essential to the success of an organization. Every stage of the HRM process plays a critical role in achieving the organization's goals, and HRM managers must ensure that every stage is executed correctly.

We can start by finding the percentage of Alonzo's current friends who chose the Costume Party theme:

Costume Party percentage = (5/30) x 100% = 16.67%

We can then use this percentage to predict how many of the additional 40 friends will choose the Costume Party theme:

Number of new friends who choose Costume Party = (16.67/100) x 40 = 6.67

Since we cannot have a fraction of a person, we can round up to predict that 7 of the additional 40 friends will choose the Costume Party theme.

The value of the triple integral is π/4.

The given function is f(x,y,z) = z(x^2 + y^2 + z^2)^(-3/2).

We need to evaluate the triple integral over the part of the ball x^2 + y^2 + z^2 ≤ 1 defined by z ≥ 0.5.

Converting to spherical coordinates, we have x = ρsinφcosθ, y = ρsinφsinθ, and z = ρcosφ. The limits of integration are ρ = 0 to 1, φ = 0 to π/3, and θ = 0 to 2π.

Then we draw a circle with radius 4 centered at the projection and extend a vertical line downwards by 3 units to find the point in space.

To find the rectangular coordinates, we use the formulas x = r cos θ and y = r sin θ, where r is the radius and θ is the angle in the xy-plane measured counterclockwise from the positive x-axis. Thus, x = 4 cos(π/3) = 2 and y = 4 sin(π/3) = 2√3. The z-coordinate is already given as -3, so the rectangular coordinates of the point are (2, 2√3, -3).

The analysis of variance (ANOVA) is a procedure that allows statisticians to compare two or more population means.

ANOVA is a statistical technique used to determine if there is a significant difference between the means of two or more groups. It works by analyzing the variation between groups compared to the variation within groups. If the variation between groups is significantly larger than the variation within groups, then it suggests that there is a significant difference between the means of the groups. ANOVA is commonly used in many fields, including social sciences, engineering, and biology, to name a few. While ANOVA can be used to compare other statistical measures such as variances and standard deviations, its primary purpose is to compare means. For example, if we want to determine if there is a significant difference in the mean heights of students in different grades, we could use ANOVA to compare the means of each grade level.

The given limit can be expressed as the definite integral:

∫[0 to 1] 3x^8 dx

To express the limit as a definite integral, we can use the definition of a Riemann sum. Let's consider the function f(x) = x^8.

The given limit can be rewritten as:

lim(n→∞) Σ[i=1 to n] (3i^8 / n^9)

Now, let's express this limit as a definite integral. We can approximate the sum using equal subintervals of width Δx = 1/n. The value of i can be replaced with x = iΔx = i/n. The summation then becomes:

lim(n→∞) Σ[i=1 to n] (3(i/n)^8 / n^9)

This can be further simplified as:

lim(n→∞) (1/n) Σ[i=1 to n] (3(i/n)^8 / n)

Taking the limit as n approaches infinity, the sum can be written as:

lim(n→∞) (1/n) ∑[i=1 to n] (3(i/n)^8 / n) ≈ ∫[0 to 1] 3x^8 dx

The Maclaurin series for f(x) is f(x) = 16x^2 - 914.6667x^3 + O(x^4).

To find the Maclaurin series for the function f(x) = 8x^2sin(7x), we need to compute its derivatives and evaluate them at x=0:

f(x) = 8x^2sin(7x)

f'(x) = 16xsin(7x) + 56x^2cos(7x)

f''(x) = 16(2cos(7x) - 49xsin(7x)) + 112xcos(7x)

f'''(x) = 16(-98sin(7x) - 343xcos(7x)) + 112(-sin(7x) + 7xcos(7x))

f''''(x) = 16(-2401cos(7x) + 2401xsin(7x)) + 784xsin(7x)

At x=0, all the terms with sin(7x) vanish, and we are left with:

f(0) = 0

f'(0) = 0

f''(0) = 32

f'''(0) = -5488

f''''(0) = 0

Thus, the Maclaurin series for f(x) is:

f(x) = 32x^2 - 2744x^3 + O(x^4)

We can also find the coefficients directly by using the formula:

cn = f^(n)(0) / n!

where f^(n)(0) is the nth derivative of f(x) evaluated at x=0. Using this formula, we get:

c0 = f(0) / 0! = 0

c1 = f'(0) / 1! = 0

c2 = f''(0) / 2! = 32 / 2 = 16

c3 = f'''(0) / 3! = -5488 / 6 = -914.6667

c4 = f''''(0) / 4! = 0 / 24 = 0

Therefore, the Maclaurin series for f(x) is:

f(x) = 16x^2 - 914.6667x^3 + O(x^4)

The associated right triangle has one angle θ whose tangent is x/6, and the adjacent side has length 6 while the opposite side has length x.

To evaluate the integral, we use the trigonometric substitution x = 6 tan(θ). Then, dx = 6 sec2(θ) dθ, and substituting in the integral we get:

∫(x^2)/(36+x^2) dx = ∫(36 tan^2(θ))/(36 + 36 tan^2(θ)) (6 sec^2(θ) dθ)

= ∫tan^2(θ) dθ

To solve this integral, we use the trigonometric identity tan^2(θ) = sec^2(θ) - 1, so we get:

∫tan^2(θ) dθ = ∫(sec^2(θ) - 1) dθ

= tan(θ) - θ + C

Substituting back x = 6 tan(θ) and simplifying, we get the final result:

∫(x^2)/(36+x^2) dx = 6(x/6 * √(1 + x^2/36) - atan(x/6) + C)

(a) To show a bijection between the set of strings in T6 that are balanced and TS, we define the function f: T6 → TS as follows:For each string x = x1x2x3x4x5x6 in T6, we compute its balance b = (x1 + x2 + x3) - (x4 + x5 + x6). Note that b is a multiple of 3 if and only if x is balanced.

We then represent b as a ternary string y = y1y2...yk in TS, where k is the smallest nonnegative integer such that 3^k > |b|. We pad y with leading zeros if necessary. Finally, we concatenate x and y to form the string f(x) = x1x2x3x4x5x6y1y2...yk in TS.

To show that f is a bijection, we need to show that it is both injective and surjective.

Injectivity: Suppose f(x) = f(x') for two strings x = x1x2x3x4x5x6 and x' = x'1x'2x'3x'4x'5x'6 in T6. Then, we have x1x2x3x4x5x6y1y2...yk = x'1x'2x'3x'4x'5x'6y'1y'2...y'k for some ternary strings y and y'. In particular, this implies that x1 + x2 + x3 - x'1 - x'2 - x'3 = 3(y'1 - y1) + 9z for some integer z, since the sum of the digits in x and x' must differ by a multiple of 3. But since each xi and x'i is either 0, 1, or 2, we have |x1 + x2 + x3 - x'1 - x'2 - x'3| ≤ 6, which implies that y'1 = y1 and z = 0. By repeating this argument for the other digits, we conclude that x = x', and hence f is injective. Surjectivity: Given any string y = y1y2...yk in TS, where k ≥ 1, we can construct a balanced string x in T6 as follows:Let b = 3(y1 + 2y2 + 4y3 + ... + 3^(k-1)yk-1) + 2yk, which is the decimal representation of y as a signed ternary number. Note that b is a multiple of 3, since the sum of the powers of 3 in the expansion of b is a multiple of 3. We then choose any three integers a, b, and c such that a + b + c = b/3, and let x1 = a, x2 = b, x3 = c. Note that such integers a, b, and c exist by the integer solution to a linear equation with three variables. Finally, we choose x4, x5, and x6 arbitrarily from T to complete the string x. It is easy to verify that x is balanced, and that f(x) = y. Therefore, f is surjective.Since f is both injective and surjective, it is a bijection.

(b) To count the number of strings in T6 that are balanced, we can use the bijection rule to count the number of strings in TS, which is 3^4 =

The general solution of the system of differential equations is:

x1 = X1t + X2t + C1

x2 = [tex](1/5)Ce^t - (4/5)X1[/tex]

X1, X2, C1, and C are arbitrary constants.

System of differential equations:

x1' = X1 + X2

x2 = 4x1 + x2

To decouple this system, we first solve for x1' in terms of X1 and X2:

x1' = X1 + X2

Next, we differentiate the second equation with respect to time t:

x2' = 4x1' + x2'

Substituting x1' = X1 + X2, we get:

x2' = 4(X1 + X2) + x2'

Rearranging this equation, we get:

x2' - x2 = 4X1 + 4X2

This is a first-order linear differential equation.

To solve for x2, we first find the integrating factor:

μ(t) = [tex]e^{(-t)[/tex]

Multiplying both sides of the equation by μ(t), we get:

[tex]e^{(-t)}x2' - e^{(-t)}x2 = 4e^{(-t)}X1 + 4e^{(-t)}X2[/tex]

Applying the product rule of differentiation to the left side, we get:

[tex](d/dt)(e^{(-t)}x2) = 4e^{(-t)}X1 + 4e^{(-t)}X2[/tex]

Integrating both sides with respect to t, we get:

[tex]e^{(-t)}x2 = -4X1e^{(-t)} - 4X2e^{(-t)} + C[/tex]

where C is an arbitrary constant of integration.

Solving for x2, we get:

[tex]x2 = Ce^t - 4X1 - 4X2[/tex]

Now, we have two decoupled differential equations:

x1' = X1 + X2

[tex]x2 = Ce^t - 4X1 - 4X2[/tex]

To find the general solution, we first solve for x1:

x1' = X1 + X2

=> x1 = ∫(X1 + X2)dt

=> x1 = X1t + X2t + C1

where C1 is an arbitrary constant of integration.

Substituting x1 into the equation for x2, we get:

x2 = [tex]Ce^t[/tex]- 4X1 - 4X2

=> x2 + 4x2 = [tex]Ce^t[/tex]- 4X1

=> 5x2 = [tex]Ce^t - 4X1[/tex]

x2 = (3/2)c1sin((sqrt(23)/8)t) - (3/2)c2cos((sqrt(23)/8)t) + 4c3

The given system of differential equations is:

x;' = X1 + X2

x2 = 4x1 + x2

To decouple the system, we need to eliminate one of the variables from the first equation. We can do this by rearranging the second equation as:

x1 = (x2 - x2)/4

Substituting this in the first equation, we get:

x;' = X1 + X2

= (x2 - x1)/4 + x2

= (3/4)x2 - (1/4)x1

Now, we can write the system as:

x;' = (3/4)x2 - (1/4)x1

x2 = 4x1 + x2

To solve this system, we can use the standard method of finding the characteristic equation:

| λ - (3/4) 1/4 |

| -4 1 |

Expanding along the first row, we get:

λ(λ-3/4) - 1/4(-4) = 0

λ^2 - (3/4)λ + 1 = 0

Solving for λ using the quadratic formula, we get:

λ = (3/8) ± (sqrt(9/64 - 1))/8

λ = (3/8) ± (sqrt(23)/8)i

Therefore, the general solution of the system is:

x1 = c1cos((sqrt(23)/8)t) + c2sin((sqrt(23)/8)t) + (3/4)c3

x2 = (3/2)c1sin((sqrt(23)/8)t) - (3/2)c2cos((sqrt(23)/8)t) + 4c3
