The second-degree Taylor polynomial for f(x) = 2x^2 - 8x + 7 about x = 0 is P(x) = 7 - 8x + 2x^2. To find the second-degree Taylor polynomial for f(x) = 2x^2 - 8x + 7 about x = 0, we need to calculate the polynomial using the formula:

P(x) = f(0) + f'(0)(x - 0) + f''(0)(x - 0)^2/2

First, let's find the derivatives of f(x):

f'(x) = 4x - 8

f''(x) = 4

Now, substitute these values into the formula:

P(x) = f(0) + f'(0)(x - 0) + f''(0)(x - 0)^2/2

= 2(0)^2 - 8(0) + 7 + (4(0) - 8)(x - 0) + 4(x - 0)^2/2

= 7 - 8x + 2x^2

The second-degree Taylor polynomial for f(x) = 2x^2 - 8x + 7 about x = 0 is P(x) = 7 - 8x + 2x^2.

Observation: The polynomial P(x) is identical to the original function f(x). This occurs because the original function is already a polynomial of degree 2. In general, when the function is a polynomial, its Taylor polynomial of the same degree will be equal to the original function.

The limits are as follows:

a) lim [f(x)g(x)] = -35

b) lim [5f(x)g(x)] = -175

c) lim [f(x) + 6g(x)] = -23

d) lim [f(x) - g(x)] = 12

To find the limits of the given expressions, we can use the properties of limits and the given information about the limits of f(x) and g(x).

a) lim [f(x)g(x)] as x approaches 5:

Using the limit product rule, the limit of the product of two functions is equal to the product of their limits if both limits exist. Therefore:

lim [f(x)g(x)] = lim f(x) * lim g(x) = 7 * (-5) = -35

b) lim [5f(x)g(x)] as x approaches 5:

Similarly, we can apply the limit product rule and the constant multiple rule to find:

lim [5f(x)g(x)] = 5 * lim f(x) * lim g(x) = 5 * 7 * (-5) = -175

c) lim [f(x) + 6g(x)] as x approaches 5:

Using the limit sum rule, the limit of the sum of two functions is equal to the sum of their limits if both limits exist. Thus:

lim [f(x) + 6g(x)] = lim f(x) + lim [6g(x)] = 7 + 6 * (-5) = 7 - 30 = -23

d) lim [f(x) - g(x)] as x approaches 5:

Similarly, applying the limit difference rule:

lim [f(x) - g(x)] = lim f(x) - lim g(x) = 7 - (-5) = 7 + 5 = 12

Therefore, the limits are as follows:

a) lim [f(x)g(x)] = -35

b) lim [5f(x)g(x)] = -175

c) lim [f(x) + 6g(x)] = -23

d) lim [f(x) - g(x)] = 12

True. The simulations for paired design and independent group design are the same, but the way data is collected differs.

In paired design, data is collected from two related samples, while in independent groups design, data is collected from two unrelated samples. Despite this difference in data collection, the simulations for both designs are the same.

The simulations for paired design and independent group design are similar because they both involve testing a null hypothesis using statistical methods. In both designs, the goal is to determine whether there is a significant difference between two groups or samples.

However, in paired design, the difference between the two samples is calculated within each pair of related observations, while in independent groups design, the difference is calculated between two unrelated samples. The simulations for both designs involve generating random data sets based on assumptions about the population parameters and testing whether the observed differences between groups are statistically significant.

The area of the right triangle is 216 square units.

Given is right triangle with height 18 units and hypotenuse 30 units we need to find the area of the right triangle,

To find the area of a right triangle, you can use the formula:

Area = (base × height) / 2

In this case, the height of the triangle is given as 18 units.

To find the base, we can use the Pythagorean theorem since the hypotenuse and height are known.

The Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Let's denote the base of the triangle as 'b'.

We have the following information:

Height (h) = 18 units

Hypotenuse (c) = 30 units

Using the Pythagorean theorem:

c² = a² + b²

30² = 18² + b²

900 = 324 + b²

b² = 900 - 324

b² = 576

b = √576

b = 24

Now that we have the height (18 units) and the base (24 units), we can substitute these values into the area formula:

Area = (base × height) / 2

Area = (24 × 18) / 2

Area = 432 / 2

Area = 216 square units

Therefore, the area of the right triangle is 216 square units.

The equilibrium price for Toyota vehicles is OMR 2050, and the equilibrium quantity is 2400 vehicles. The choke price, or the price at which the quantity supplied falls to zero, is OMR 433.

To find the equilibrium price and quantity, we set the quantity demanded (Qd) equal to the quantity supplied (Qs):

5500 - (2p/5) = 3p - 1300

Simplifying the equation, we get:

5500 - (2p/5) = 3p - 1300

-2p/5 - 3p = -1300 - 5500

-2p - 15p/5 = -6800

-2p - 3p = -6800

-5p = -6800

p = (-6800)/(-5)

p = 1360

Substituting the value of p back into either the demand or supply equation, we can find the equilibrium quantity:

Qd = 5500 - 2(1360)/5

Qd = 5500 - 2720/5

Qd = 5500 - 544

Qd = 4956

Therefore, the equilibrium price is OMR 2050 and the equilibrium quantity is 2400 vehicles.

To find the choke price, we set the quantity supplied (Qs) equal to zero:

0 = 3p - 1300

3p = 1300

p = 1300/3

p ≈ 433

Hence, the choke price for Toyota vehicles in Oman is approximately OMR 433.

The sum of three parallel vectors can only be the zero vector if all three vectors have magnitudes of zero.

a. Vectors ū, 5ū, and -5ū are related in terms of their direction and magnitude. These vectors are scalar multiples of each other, meaning that they have the same direction but different lengths or magnitudes.  Vector 5ū is obtained by multiplying vector ū by a scalar factor of 5, which results in a vector that has the same direction as ū but is five times as long. On the other hand, vector -5ū is obtained by multiplying vector ū by a scalar factor of -5, which also results in a vector that has the same direction as ū but is five times as long in the opposite direction. In summary, vectors ū, 5ū, and -5ū have the same direction but differ in magnitude.

b. No, it is not possible for the sum of three parallel vectors to be equal to the zero vector unless all three vectors have magnitudes of zero. When vectors are parallel, they have the same or opposite direction, and their sum can be determined by adding or subtracting their magnitudes. If any of the vectors has a non-zero magnitude, the sum of the three vectors will also have a non-zero magnitude and therefore cannot be equal to the zero vector. The zero vector has a magnitude of zero and represents a vector with no direction. Therefore, the sum of three parallel vectors can only be the zero vector if all three vectors have magnitudes of zero.

To find the limiting value of the population and the value of the population when t = 3, we can solve the Gompertz differential equation and use the initial condition.

(a) To find the limiting value of the population, we need to find the value of P(t) as t approaches infinity. We can do this by finding the equilibrium or steady-state solution of the differential equation.

Setting dP/dt = 0, we have:

6P(13 - ln(P)) = 0

This equation has two possible solutions:

P = 0

13 - ln(P) = 0 => ln(P) = 13 => P = e^13

Since the population cannot be negative, the limiting value of the population is P = e^13.

(b) To find the value of the population when t = 3, we can solve the differential equation using the initial condition.

Separating variables, we have:

dP / P(13 - ln(P)) = 6dt

To derive the uniformly most powerful (UMP) test for testing H: θ = θ0 against the alternative hypothesis H: θ > θ0 in the exponential family of distributions, we can use the Neyman-Pearson lemma.

The likelihood ratio test statistic is given by: λ(x) = (L(θ0) / L(x)), where L(θ) is the likelihood function. To find the UMP test, we need to find a critical region that maximizes the power function under the constraint of the specified significance level. For the exponential family of distributions, the likelihood function is given by: L(x) = c(θ) exp{∑[i=1 to n] T(x_i) - nA(θ)}, where T(x_i) are sufficient statistics and A(θ) is a function of θ.

In this case, we have a random sample of size n = 15 from N(0, θ). The likelihood function for this sample is: L(x) = (1 / √(2πθ))^n exp{-(1/2θ)∑[i=1 to n] x_i^2}, where x_i are the observed values. To find the UMP test, we can use the likelihood ratio test statistic. The critical region for the test is of the form: C = {x : λ(x) > k}, where k is chosen such that the size of the test is α = 0.05. To simplify the calculation, we can take the logarithm of the likelihood ratio: log(λ(x)) = -nlog(√(2πθ)) - (1/2θ)∑[i=1 to n] x_i^2 - (-nlog(√(2πθ0)) - (1/2θ0)∑[i=1 to n] x_i^2).

Simplifying further, we get: log(λ(x)) = (n/2)log(θ0/θ) + (1/2)∑[i=1 to n] x_i^2 (θ0 - θ). Now, for the test of size α = 0.05, we need to find the critical value k such that the probability under the null hypothesis H: θ = θ0 of observing λ(x) > k is α. In this case, since we are testing H: θ = 3 against the alternative H: θ > 3, we can set θ0 = 3. We can calculate the critical value k from the distribution of the test statistic under the null hypothesis. Once we have the critical region, we can construct the UMP test for the given problem.

Since the dot product of u and v is not zero, i.e. U.V = 86, the vectors are not orthogonal.

To determine if the vectors are parallel, we can compare their direction or compute the angle between them. One way to check if they are parallel is to divide one vector by the other and see if they are scalar multiples of each other.

To find the specified scalar, let's first calculate the sum of the vectors u, v, u, and w.

Given:

u = 4i - j

v = 5i + j

w = i + 7j

Adding u and v:

u + v = (4i - j) + (5i + j)

= 4i + 5i - j + j

= 9i

Now adding u, v, and w:

u + v + u + w = (4i - j) + (5i + j) + (4i - j) + (i + 7j)

= (4i + 5i + 4i + i) + (-j + j + 7j)

So, the sum of the vectors u, v, u, and w is 14i + 7j.

Next, we need to find the values of λ that make the determinant of (A - λI) equal to zero. So we solve:

|A - λI| = 0

Expanding the determinant, we get a polynomial equation in λ. Solving this equation will give us the eigenvalues.

Once we have the eigenvalues, we can substitute each value back into (A - λI)v = 0 and solve for the corresponding eigenvectors.

b) To verify the eigenvectors, we substitute the eigenvector values back into the equation Av = λv and check if it holds true. For each eigenvector, we multiply it by matrix A and compare the result to λ times the eigenvector. If they are equal, the eigenvector is verified.

For the given matrix A and the first pair of eigenvalue and eigenvector (0, [1, -2, 0, 2]), we substitute the values back into the equation:

A * [1, -2, 0, 2] = 0 * [1, -2, 0, 2]

The double integral ∬ x²e dr dy evaluates to (x²e)(d - c)(q - p)(d - c).

To evaluate the double integral ∬ x²e dr dy by reversing the order of integration, we need to determine the limits of integration for both variables.

Given that the integral is written as ∬ x²e dr dy, where dr represents the infinitesimal radial distance and dy represents the infinitesimal height, we can express it as follows:

∬ x²e dr dy = ∫∫ x²e dr dy.

To reverse the order of integration, we'll start by integrating with respect to dr first.

For dr, we need to determine the limits of integration. Since no specific boundaries are mentioned in the given integral, we'll assume a lower limit r = a and an upper limit r = b.

Therefore, the integral becomes:

∫∫ x²e dr dy = ∫ a to b (∫ x²e dy) dr.

Now, we integrate with respect to y, treating x²e as a constant:

∫ x²e dy = x²e y.

Next, we integrate x²e y with respect to y, considering the limits of integration for y, which are not specified in the given integral.

Since no specific limits are provided, we'll assume a lower limit y = c and an upper limit y = d.

Therefore, the integral becomes:

∫ a to b (∫ x²e dy) dr = ∫ a to b (x²e)(d - c) dr.

Now, we integrate (x²e)(d - c) with respect to r, considering the limits of integration for r, which are not specified in the given integral.

Since no specific limits are provided, we'll assume a lower limit r = p and an upper limit r = q.

Therefore, the integral becomes:

∫ p to q ∫ a to b (x²e)(d - c) dr dy.

Finally, we integrate (x²e)(d - c) with respect to r:

∫ p to q (x²e)(d - c)(q - p) dy.

Simplifying the expression:

(x²e)(d - c)(q - p)(y) evaluated from y = c to y = d.

Substituting the limits of integration and simplifying further:

(x²e)(d - c)(q - p)(d - c).

Therefore, by reversing the order of integration, the double integral ∬ x²e dr dy evaluates to (x²e)(d - c)(q - p)(d - c).

-8(1)^3 - 3(1)^2 - 10(1) + C₁ = -23

-8 - 3 - 10 + C₁ = -23

-21 + C₁ = -23

C₁ = -23 + 21

C₁ = -2

From the condition f(1) = -28:

-2(1)^4 - (1)^3 - 5(1)^2 + (-2)(1) + C₂ = -28

-2 - 1 - 5 - 2 + C₂ = -28

-10 + C₂ = -28

C₂ = -28 + 10

C₂ = -18

Now we have the specific solution for the initial value problem:

f(x) = -2x^4 - x^3 - 5x^2 - 2x - 18

Therefore, the solution to the given initial value problem is f(x) = -2x^4 - x^3 - 5x^2 - 2x - 18.

1.(a)The equations for the medians of triangle ABC are

y = x - 1

y = 3x - 3

x= -2.

(b)The three medians are concurrent, by finding coordinates for their common point.

2.The largest square that can fit inside the right triangle has sides measuring 5 cm.

3.The uniform mowed border has a width of 24 yards.

4.Angles ABC and BCA both measure 62 degrees.

5.Angles BAC and PAQ are not congruent due to the difference in the slopes of the corresponding sides AB and AC.

How can the concurrent medians of a triangle be used to locate its centroid?

The concurrent medians of a triangle can be used to locate its centroid, which is the point of intersection of the medians. To find the centroid, one can calculate the midpoints of each side of the triangle and determine the equations of the medians. By solving the system of equations formed by the medians, the coordinates of the common point, known as the centroid, can be found. The centroid is an important point in a triangle as it divides each median into segments in a ratio of 2:1, meaning that the distance from the centroid to a vertex is twice the distance from the centroid to the midpoint of the opposite side.

1.(a) To find the equations for the medians of triangle ABC, we need to determine the midpoints of each side and find the slopes of the corresponding medians.

Let's label the midpoints of the sides as D, E, and F,

where:

D is the midpoint of side BC,

E is the midpoint of side AC, and

F is the midpoint of side AB.

The coordinates of the midpoints are as follows:

D = [[tex]\frac{0 + 6}{2}, \frac{6 + 0}{2}[/tex]] = [3, 3]

E = [[tex]\frac{-4 + 6}{2},\frac{0 + 0}{2}[/tex]] = [1, 0]

F = [[tex]\frac{-4 + 0}{2},\frac{0 + 6}{ 2}[/tex]] = [-2, 3]

Now, let's find the slopes of the medians using the formula[tex]\frac{y_2 - y_1}{x_2 - x_1}:[/tex]

The equation of the median from A to D:

[tex]m_1 =\frac{3 - 0}{3 - 0} = 1[/tex]

Using the point-slope form, we have: y - 0 = 1(x - 1) [tex]\implies[/tex] y = x - 1

The equation of the median from B to E:

m₂ =[tex]\frac{0 - 6}{1 - 3}[/tex] = 3

Using the point-slope form, we have:

y - 6 = 3(x - 3) [tex]\implies[/tex] y = 3x - 3

The equation of the median from C to F:

m₃ = [tex]\frac{3 - 3}{-2 - (-4)}[/tex] = 0

Since the slope is 0, the equation of the median is simply the equation of the line x= -2.

(b) To show that the medians are concurrent, we need to find the point of intersection of these three median lines.

By solving the system of equations formed by the equations of the medians, we can find the coordinates of the common point.

Solving y = x - 1 and y = 3x - 3,

we get: x - 1 = 3x - 3 -> 2x = 2 -> x = 1

Substituting x = 1 into y = x - 1, we get: y = 1 - 1 = 0

Therefore, the coordinates of the point of concurrence (centroid) are (1, 0).

2.To determine the maximum size of a square that can fit inside a right triangle with legs of 5 cm and 12 cm, we need to find the length of the square's side.

The length of the square's side will be equal to the length of the shorter leg of the right triangle (5 cm).

Therefore, the largest square that can fit inside the right triangle has sides measuring 5 cm.

3.The uniform mowed border's width when Robin is halfway done can be calculated by finding half the perimeter of the rectangular field.

Given that the rectangular field measures 24 yards by 32 yards, the perimeter is calculated as:

P = 2(length + width) = 2(24 + 32) = 2(56) = 112 yards.

To find the width of the uniform mowed border when Robin is halfway done, we divide the perimeter by 2 and subtract the original width of the rectangular field:

Width of the uniform mowed border = ([tex]\frac{112}{2}[/tex]) - 32 = 56 - 32 = 24 yards.

Therefore, when Robin is halfway done, the uniform mowed border has a width of 24 yards.

4.In an isosceles triangle ABC, with AB = BC, and angle BAC measuring 56 degrees, we need to find the measures of the remaining two angles.

Since AB = BC, angles ABC and BCA are congruent. Let's denote the measure of angles ABC and BCA as x.

According to the triangle angle sum property, the sum of the interior angles in a triangle is always 180 degrees. Therefore, we can write the following equation:

56 + x + x = 180

Simplifying the equation:

56 + 2x = 180

2x = 180 - 56

2x = 124

x = 62

So, angles ABC and BCA both measure 62 degrees.

5.To determine if angles BAC and PAQ are congruent, we need to compare their measures.

Angle BAC is formed by the vertices A, B, and C, which have the coordinates (0, 0), (4, 3), and (2, 4) respectively.

Using the slope formula, we can calculate the slopes of AB and AC: Slope of AB = [tex]\frac{3 - 0}{4 - 0}=\frac{3}{4}[/tex]

Slope of AC =[tex]\frac{4 - 0}{2 - 0} =\frac{ 4}{2}= \frac{2}{1}[/tex] = 2

The slopes of AB and AC are not equal, so angles BAC and PAQ are not congruent.

Therefore, angles BAC and PAQ are not congruent due to the difference in the slopes of the corresponding sides AB and AC.

The set of all elements of interest in a study is  (d) a population.

The correct answer is (d) a population.

In statistics and research, a population refers to the entire group or collection of individuals, objects, or elements of interest that we want to study or make inferences about. It represents the complete set from which a sample is drawn. The population can be finite or infinite, depending on the context.

For example, if we are studying the heights of all adult males in a particular country, the population would be the entire group of adult males in that country. Similarly, if we are interested in understanding the preferences of all smartphone users globally, the population would be the entire set of smartphone users worldwide.

In contrast, a sample refers to a subset or smaller group selected from the population. The sample is often chosen to represent the population in a study, as it is usually impractical or impossible to collect data from every individual in the population.

Therefore, the set of all elements of interest in a study is referred to as the population.

The equation of the perpendicular bisector of a line segment can be found by determining the midpoint of the line segment and its slope. The midpoint is obtained by averaging the x-coordinates and the y-coordinates of the endpoints. The slope of the line segment is calculated using the formula (y2 - y1) / (x2 - x1). Once the midpoint and slope are determined, the equation of the perpendicular bisector can be obtained by using the point-slope form of a linear equation.

In this case, the endpoints of the line segment are (1, 3) and (5, 9). The midpoint is found by averaging the x-coordinates and the y-coordinates, giving us (3, 6). The slope of the line segment is (9 - 3) / (5 - 1) = 1. The slope of the perpendicular bisector is the negative reciprocal of the line segment's slope, which is -1. Therefore, the equation of the perpendicular bisector can be written in point-slope form as y - 6 = -1(x - 3).

Simplifying the equation, we get y - 6 = -x + 3, which can be further simplified to y = -x - 3 + 6, and finally, y = -x + 3. Thus, the equation of the perpendicular bisector of the line segment joining (1, 3) and (5, 9) is y = -x + 3.

To find the length of the band of steel, we need to calculate the circumference of both pipes and add them together.
The circumference of a circle is given by the formula 2πr, where r is the radius of the circle.
So, the circumference of the first pipe is 2π(9) = 18π, and the circumference of the second pipe is 2π(11) = 22π.
Adding them together, we get the total circumference of the pipes as 18π + 22π = 40π.
To round off to the hundredths place value, we can use 3.14 as an approximation for π and get:
40π ≈ 40(3.14) = 125.6
Therefore, the length of the band of steel that wraps the pipes together is approximately 125.6 units.

The circumference of a circle is the distance around its outer edge or boundary. It is calculated using the formula:

Circumference = 2πr

where "π" represents the mathematical constant pi (approximately 3.14159) and "r" represents the radius of the circle. The radius is the distance from the center of the circle to any point on its edge.

The vector u = [30 10 1] is not in the plane in [tex]R^3[/tex] spanned by the columns of A = [-3 10 -1 7 1 1].

To determine whether vector u lies in the plane spanned by the columns of matrix A , you can check whether vector u can be expressed as a linear combination of the columns of A .

Denote the columns of A as c1 = [-3 7], c2 = [10 1], c3 = [1 1].

Check if there is a scalar x, y, z such that u = xc1 + yc2 + z*c3.

Substituting the values, we get [30 10 1] = x*[-3 7] + y*[10 1] + z*[1 1].

Expanding the equation, we get the following two equations:

-3x + 10y + z = 30

7x+y+z=10

Solving the system of equations reveals that it is inconsistent. There is no x, y, z value that satisfies both equations at the same time.

(a)  The eigenvalues of the matrix E can be found by solving the characteristic equation det(E - λI) = 0, where λ is the eigenvalue and I is the identity matrix.

(b) To compute an eigenvector for each eigenvalue of matrix E, we need to solve the equation (E - λI)v = 0, where λ is the eigenvalue and v is the corresponding eigenvector.

(c)To prove that the eigenvectors of matrix E are linearly independent, we need to show that no linear combination of the eigenvectors results in the zero vector other than the trivial combination where all coefficients are zero.

(a)Let's compute the eigenvalues of matrix E.

E = [[3, 5], [2, 4]]

To find the eigenvalues, we solve the characteristic equation:

det(E - λI) = 0

Substituting the values into the equation:

det([[3, 5], [2, 4]] - [[λ, 0], [0, λ]]) = 0

Simplifying:

det([[3 - λ, 5], [2, 4 - λ]]) = 0

Expanding the determinant:

(3 - λ)(4 - λ) - 2 * 5 = 0

Simplifying further:

(12 - 7λ + λ^2) - 10 = 0

λ^2 - 7λ + 2 = 0

Solving this quadratic equation, we find two eigenvalues:

λ₁ ≈ 6.8541

λ₂ ≈ 2.1459

Therefore, the eigenvalues of matrix E are approximately 6.8541 and 2.1459.

(b)For the first eigenvalue λ₁ ≈ 6.8541:

Let's solve the equation (E - λ₁I)v₁ = 0:

Substituting the values into the equation:

[[3, 5], [2, 4]] - [[6.8541, 0], [0, 6.8541]] * [[x₁], [y₁]] = [[0], [0]]

Simplifying:

[[3 - 6.8541, 5], [2, 4 - 6.8541]] * [[x₁], [y₁]] = [[0], [0]]

Solving the system of equations, we find the eigenvector v₁:

[[-3.8541, 5], [2, -2.8541]] * [[x₁], [y₁]] = [[0], [0]]

Solving this system of equations, we get x₁ ≈ 1.303 and y₁ ≈ 1.

Therefore, the eigenvector corresponding to the eigenvalue λ₁ is approximately [1.303, 1].

For the second eigenvalue λ₂ ≈ 2.1459:

Let's solve the equation (E - λ₂I)v₂ = 0:

Substituting the values into the equation:

[[3, 5], [2, 4]] - [[2.1459, 0], [0, 2.1459]] * [[x₂], [y₂]] = [[0], [0]]

Simplifying:

[[3 - 2.1459, 5], [2, 4 - 2.1459]] * [[x₂], [y₂]] = [[0], [0]]

Solving the system of equations, we find the eigenvector v₂:

[[0.8541, 5], [2, 1.8541]] * [[x₂], [y₂]] = [[0], [0]]

Solving this system of equations, we get x₂ ≈ -5.854 and y₂ ≈ 1.

Therefore, the eigenvector corresponding to

the eigenvalue λ₂ is approximately [-5.854, 1].

(c)Let's consider the eigenvectors v₁ ≈ [1.303, 1] and v₂ ≈ [-5.854, 1] that we computed earlier.

To prove linear independence, we need to show that the only solution to the equation c₁v₁ + c₂v₂ = 0, where c₁ and c₂ are constants, is c₁ = c₂ = 0.

Substituting the eigenvectors into the equation:

c₁ * [1.303, 1] + c₂ * [-5.854, 1] = [0, 0]

Expanding the equation:

[1.303c₁ - 5.854c₂, c₁ + c₂] = [0, 0]

From the first component of the equation, we have:

1.303c₁ - 5.854c₂ = 0

From the second component of the equation, we have:

c₁ + c₂ = 0

Solving this system of equations, we find c₁ = c₂ = 0.

Since the only solution to the equation is the trivial solution, we can conclude that the eigenvectors v₁ and v₂ are linearly independent.

Therefore, we have shown that the eigenvectors of matrix E, v₁ ≈ [1.303, 1] and v₂ ≈ [-5.854, 1], are linearly independent.
