The angle ∠CEA in the circle is 26 degrees.

If two chords intersect inside a circle, then the measure of the angle formed is one half the sum of the measure of the arcs intercepted by the angle and its vertical angle.

Therefore, using the chord intersection theorem let's find the angle ∠CEA.

Therefore,

∠CEA = 1 / 2 (87 - 35)

∠CEA = 1 / 2 (52)

∠CEA = 52 / 2

Consider the second-order differential equation with initial conditions u(1) = 1, u'(1) = 0, v(1) = 0, v'(1) = -1.The given equation is:u'' + 2u' + 5u = 0 and the characteristic equation of this second-order differential equation is λ² + 2λ + 5 = 0.

Now, we have two complex roots for the characteristic equation which is given asλ₁ = -1 + 2i and λ₂ = -1 - 2i.Hence, the general solution for this equation is u(x) = e⁻x (c₁ cos 2x + c₂ sin 2x) and the general solution for v(x) is v(x) = e⁻x (-c₁ sin 2x + c₂ cos 2x)

Using the initial conditions, we can determine the values of c₁ and c₂ as follows;u(1) = e⁻¹ (c₁ cos 2 + c₂ sin 2) = 1u'(1) = e⁻¹ [-c₁ sin 2 + c₂ cos 2] = 0v(1) = e⁻¹ [-c₁ sin 2 + c₂ cos 2] = 0v'(1) = e⁻¹ [-c₁ cos 2 - c₂ sin 2] = -1Using the first equation we can solve for c₁ which is given asc₁ = e¹ [(1-c₂ sin 2)/cos 2]Using the second and third equations, we have the relationship sin 2c₂ = 0 and c₂ = ±1.Then the values of c₁ are given by c₁ = 2e¹/3, and c₁ = -2e¹/3.So, the solutions for the initial value problem are:u(x) = e⁻x (2e¹/3 cos 2x - 2e¹/3 sin 2x) and v(x) = e⁻x (-2e¹/3 sin 2x - 2e¹/3 cos 2x)Therefore, the solution for the given second-order differential equation is u(x) = e⁻x (2/3e cos 2x - 2/3e sin 2x) - e⁻x (2/3e cos 2x + 2/3e sin 2x) = -2e⁻x/3 sin 2x.The answer is -2e⁻x/3 sin 2x.

The Chi-Squared DistributionIn probability theory and statistics, the Chi-Squared distribution is one of the distributions. This distribution arises when the sum of the squares of the independent random variables is distributed. The distribution is given by the positive square root of the random variable z. We usually call the distribution as a chi-squared distribution with degrees of freedom denoted by ν. The distribution has a wide range of applications in various fields, including bioinformatics, physics, finance, and many others. 

(a). The 95th percentile of the chi-squared distribution with ν = 10The Chi-squared distribution with degrees of freedom ν=10 has a 95th percentile of approximately 18.3. The formula for determining the 95th percentile of the Chi-squared distribution with degrees of freedom ν is as follows:P(χ² ≤ p0.95) = 1 - αwhere α is the significance level. The value of α for 95% confidence is 0.05. Using the inverse Chi-Square distribution function in Microsoft Excel, we can find that the 95th percentile of the Chi-squared distribution with degrees of freedom ν=10 is approximately 18.3.

(b). The 5th percentile of the chi-squared distribution with ν = 10The Chi-squared distribution with degrees of freedom ν=10 has a 5th percentile of approximately 3.2. The formula for determining the 5th percentile of the Chi-squared distribution with degrees of freedom ν is as follows:

P(χ² ≤ p0.05) = αwhere α is the significance level. The value of α for 95% confidence is 0.05.

Using the inverse Chi-Square distribution function in Microsoft Excel, we can find that the 5th percentile of the Chi-squared distribution with degrees of freedom ν=10 is approximately 3.2.

(c). P(10.98 ≤ Χ² ≤ 36.78), where Χ² is a chi-squared rv with ν = 22

The probability of 10.98 ≤ Χ² ≤ 36.78 is the same as the probability of Χ² ≤ 36.78 - Χ² ≤ 10.98.

Using the cumulative distribution function for the Chi-Squared distribution with degrees of freedom ν=22 in Microsoft Excel, we get P(10.98 ≤ Χ² ≤ 36.78) = P(Χ² ≤ 36.78) - P(Χ² ≤ 10.98)= CHISQ.DIST.RT(36.78, 22) - CHISQ.DIST.RT(10.98, 22)= 0.9572 - 0.0351= 0.9221

(d). P(Χ² < 14.611 or Χ² > 37.652), where Χ² is a chi-squared rv with ν = 25The probability of Χ² < 14.611 or Χ² > 37.652 is the same as the probability of Χ² ≤ 14.611 - Χ² ≥ 37.652. Using the cumulative distribution function for the Chi-Squared distribution with degrees of freedom ν=25 in Microsoft Excel, we get P(Χ² < 14.611 or Χ² > 37.652) = P(Χ² ≤ 14.611) + (1 - P(Χ² ≤ 37.652))= CHISQ.DIST.RT(14.611, 25) + (1 - CHISQ.DIST.RT(37.652, 25))= 0.025 - 0.0449= -0.0199However, the probability cannot be negative. Thus, we can say that the probability of Χ² < 14.611 or Χ² > 37.652 is zero. Therefore,P(Χ² < 14.611 or Χ² > 37.652) = 0

The takt time for the given system, where the total time per shift is 430 minutes, there is one shift, workers have two 18-minute breaks, and 40 minutes for lunch, and the daily demand is 356 units, is 1.21 minutes per cycle.

Takt time is calculated by dividing the available production time by the customer demand. In this case, the available production time is the total time per shift minus the break and lunch times.

Total time per shift = 430 minutes

Break time = 2 breaks * 18 minutes = 36 minutes

Lunch time = 40 minutes

Available production time = Total time per shift - Break time - Lunch time

= 430 minutes - 36 minutes - 40 minutes

= 354 minutes

To calculate the takt time, we divide the available production time by the daily demand:

Takt time = Available production time / Daily demand

= 354 minutes / 356 units

≈ 0.9944 minutes per unit

Answer:

x1 = s

x2 = t

x3 = -2s - 2t

x4 = 2s + t

Step-by-step explanation:

We can arrive at this solution by the following steps:

We are given two equations:

x1 + 2x2 + 2x3 + x4 = 0

2x1 + 4x2 + 2x3 - x4 = 1

To solve for x1 and x2 in terms of s and t, we choose two of the variables to be the parameters s and t. Let's choose:

x1 = s

x2 = t

Now, we can substitute x1 = s and x2 = t into the first equation:

s + 2t + 2x3 + x4 = 0

Solving for x3:

2x3 = -s - 2t

x3 = -2s - 2t

Substitute into the second equation:

2s + 4t + 2(-2s - 2t) - x4 = 1

2s + 4t - 4s - 4t - x4 = 1

-2s - x4 = 1

x4 = 2s + 1

So the general solution can be written as the 4 equations:

x1 = s

x2 = t

x3 = -2s - 2t

x4 = 2s + t

The Laplace transform of the solution is Y(s) = (5 + e^(-5s)) / (s + 1).

To find the Laplace transform of the solution, we first take the Laplace transform of the given differential equation. Applying the Laplace transform to both sides of the equation and using the properties of the Laplace transform, we obtain:

sY(s) - y(0) + Y(s) = 5 + e^(-5s)

Substituting y(0) = 0, we simplify the equation to:

(s + 1)Y(s) = 5 + e^(-5s)

Dividing both sides by (s + 1), we get:

Y(s) = (5 + e^(-5s)) / (s + 1)

Therefore, the Laplace transform of the solution is Y(s) = (5 + e^(-5s)) / (s + 1).

The solution y(t) is y(t) = 5e^(-t) + h(t-5), where h(t) is the Heaviside step function.

To obtain the solution in the time domain, we need to take the inverse Laplace transform of Y(s). Using the properties and inverse Laplace transform table, we find:

L^(-1) [Y(s)] = L^(-1) [(5 + e^(-5s)) / (s + 1)] = 5e^(-t) + L^(-1) [1 / (s + 1)]

The inverse Laplace transform of 1 / (s + 1) is the Heaviside step function, h(t), which is defined as 1 for t ≥ 0 and 0 for t < 0. Therefore, the solution y(t) is given by:

y(t) = 5e^(-t) + h(t-5)

The solution can be expressed as a piecewise defined function:

y(t) = 5e^(-t) for 0 ≤ t < 5

y(t) = 5e^(-t) + 1 for t ≥ 5

If t = 5, the value of y(t) is given by the second piece of the piecewise function, which is 5e^(-5) + 1. At t = 5, the graph of the solution experiences a sudden jump or discontinuity, increasing by a value of 1.

- Functions 1, 2, 3, and 4 are homomorphisms, and their respective kernels are the set of real numbers, positive real numbers, real numbers except 0, and positive rational numbers.

- Function 5 is a homomorphism, and its kernel is the set of pairs (x, 0).

- Function 6 is not a homomorphism.

To verify if a given function is a homomorphism and find its kernel, we need to check two conditions:

1. The function preserves the operation: If the function is between two algebraic structures with an operation (e.g., addition or multiplication), it should satisfy f(x * y) = f(x) * f(y).

2. The function preserves the identity: If there is an identity element in the algebraic structures, the function should map the identity element to the identity element.

Let's go through each of the given functions:

1. f: C → R, where f(a + bi) = b.

  - To verify if it is a homomorphism, we check f((a + bi) * (c + di)) = f(a + bi) * f(c + di).

  - (a + bi) * (c + di) = (ac - bd) + (ad + bc)i

  - f((a + bi) * (c + di)) = f((ac - bd) + (ad + bc)i) = ad + bc = f(a + bi) * f(c + di)

  - The function preserves the operation, so it is a homomorphism.

  - The kernel of f is the set of complex numbers where f(a + bi) = 0. In this case, it is the set of complex numbers with zero imaginary part, i.e., the set of real numbers.

2. g: R* → Z₂, where g(x) = 0 if x > 0 and g(x) = 1 if x < 0.

  - To verify if it is a homomorphism, we check g(x * y) = g(x) * g(y).

  - For positive x and y, g(x * y) = 0 and g(x) * g(y) = 0 * 0 = 0.

  - For negative x and y, g(x * y) = 1 and g(x) * g(y) = 1 * 1 = 1.

  - The function preserves the operation, so it is a homomorphism.

  - The kernel of g is the set of real numbers mapped to the identity element of Z₂, which is 0. So, the kernel is the set of positive real numbers.

3. h: R* → R*, where h(x) = x³.

  - To verify if it is a homomorphism, we check h(x * y) = h(x) * h(y).

  - h(x * y) = (xy)³ = x³ * y³ = h(x) * h(y)

  - The function preserves the operation, so it is a homomorphism.

  - The kernel of h is the set of real numbers mapped to the identity element of R*, which is 1. So, the kernel is the set of real numbers except 0.

4. f: Q* → Q**, where f(x) = |x|.

  - To verify if it is a homomorphism, we check f(x * y) = f(x) * f(y).

  - f(x * y) = |xy| = |x| * |y| = f(x) * f(y)

  - The function preserves the operation, so it is a homomorphism.

  - The kernel of f is the set of rational numbers mapped to the identity element of Q**, which is 1. So, the kernel is the set of positive rational numbers.

5. g: QxZ → Z, where g((x, y)) = y.

  - To verify if it is a homomorphism, we check g((x

₁, y₁) + (x₂, y₂)) = g((x₁, y₁)) + g((x₂, y₂)).

  - g((x₁, y₁) + (x₂, y₂)) = g((x₁ + x₂, y₁ + y₂)) = y₁ + y₂

  - g((x₁, y₁)) + g((x₂, y₂)) = y₁ + y₂

  - The function preserves the operation, so it is a homomorphism.

  - The kernel of g is the set of pairs (x, y) mapped to the identity element of Z, which is 0. So, the kernel is the set of pairs (x, 0).

6. h: C → C, where h(x) = x⁴.

  - To verify if it is a homomorphism, we check h(x + y) = h(x) + h(y).

  - h(x + y) = (x + y)⁴ = x⁴ + 4x³y + 6x²y² + 4xy³ + y⁴

  - h(x) + h(y) = x⁴ + y⁴

  - The function does not preserve the operation, so it is not a homomorphism.

The resolved shear stress for the (1 1 01 1 1] slip system in a BCC iron single crystal under a stress of 92 MPa in the [0 0 1] direction is 39.63 MPa.

The resolved shear stress is calculated using the formula: resolved shear stress = applied stress * cos(theta),

where theta is the angle between the applied stress direction and the slip direction.

In this case, the slip direction is [1 1 0] and the applied stress direction is [0 0 1]. The angle between these two directions can be calculated using the dot product:

cos(theta) = ([1 1 0] • [0 0 1]) / (| [1 1 0] | * | [0 0 1] |) = 0

Since the angle between the slip direction and the applied stress direction is 0, the resolved shear stress is equal to the applied stress: resolved shear stress = 92 MPa.

Therefore, the resolved shear stress for the (1 1 01 1 1] slip system is 92 MPa.

sin θ = 7/25

cos θ = -24/25

tan θ = -7/24

b. the point (-3, -6), the exact values of the six trigonometric functions are:

sin θ = -2/√5

cos θ = -1/√5

tan θ = 2

To find the exact values of the six trigonometric functions of an angle θ, we can use the given coordinates of a point on the terminal side of the angle in standard position.

(a) For the point (-24, 7):

To determine the trigonometric functions, we first need to find the values of the adjacent side, opposite side, and hypotenuse of the right triangle formed by the given coordinates.

The adjacent side is the x-coordinate: adjacent = -24

The opposite side is the y-coordinate: opposite = 7

Using the Pythagorean theorem, we can calculate the hypotenuse:

hypotenuse = √((-24)^2 + 7^2) = √(576 + 49) = √625 = 25

Now we can find the trigonometric functions:

sin θ = opposite / hypotenuse = 7 / 25

cos θ = adjacent / hypotenuse = -24 / 25

tan θ = opposite / adjacent = 7 / -24 (or -7/24)

Since we have only found the values for sine, cosine, and tangent, we leave the values for cosecant, secant, and cotangent blank as they are the reciprocals of the corresponding trigonometric functions.

Therefore, for the point (-24, 7), the exact values of the six trigonometric functions are:

sin θ = 7/25

cos θ = -24/25

tan θ = -7/24

(b) For the point (-3, -6):

Using the same method as above, we can find the values of the trigonometric functions for this point.

adjacent = -3

opposite = -6

hypotenuse = √((-3)^2 + (-6)^2) = √(9 + 36) = √45 = 3√5

sin θ = opposite / hypotenuse = -6 / (3√5) = -2/√5

cos θ = adjacent / hypotenuse = -3 / (3√5) = -1/√5

tan θ = opposite / adjacent = -6 / -3 = 2

Again, we leave the values for cosecant, secant, and cotangent blank as they are the reciprocals of the corresponding trigonometric functions.

Therefore, for the point (-3, -6), the exact values of the six trigonometric functions are:

sin θ = -2/√5

Based on the given information, the test statistic for the hypothesis test is 1.16, and the critical value is 1.282. In hypothesis testing. Therefore, the correct answer is c.

Since the test statistic of 1.16 does not exceed the critical value of 1.282, we fail to reject the null hypothesis.

Interpreting the results, there is not enough evidence to support the claim that the proportion of accurate scans of the bar coding system is greater than 95%. This means that based on the sample data, we do not have sufficient evidence to conclude that the store owner's claim is true. However, it is important to note that failing to reject the null hypothesis does not necessarily mean that the claim is false; it simply means that we do not have enough evidence to support the claim based on the sample data and the chosen level of significance.

Without specific information about the number of cards and red fives, the probability cannot be determined.

To calculate the probability of drawing a red five from a group of cards, we need to know the total number of cards and the number of red fives. Let's assume the total number of cards is 52 in a standard deck, with 26 red cards (diamonds and hearts) and 4 fives (regardless of color). If all cards are equally likely to be drawn, the probability of selecting a red five would be the number of red fives (4) divided by the total number of cards (52), resulting in a probability of 4/52, which simplifies to 1/13. Therefore, the probability of drawing a red five in this case would be approximately 0.0769 or 7.69%.

The most appropriate completion is (c) ... is not a solution to this problem because it does not depend on θ.

In Laplace's equation, the function u satisfies the equation Δu = 0, where Δ is the Laplacian operator. When considering the boundary condition u(r, 0) = −1 + log(r), it is important to note that Laplace's equation is a partial differential equation in terms of both r and θ. The given function u(r, 0) = −1 + log(r) depends only on r and does not have any dependence on the angular variable θ.

Therefore, the function does not satisfy Laplace's equation since it does not depend on one of the variables involved. The solution to Laplace's equation on the disc must involve both r and θ variables to satisfy the equation and boundary conditions appropriately.

The statement "If U is invariant under every linear operator on V, then U = {0} or U = V" is false.

To prove or disprove the statement: "If U is invariant under every linear operator on V, then U = {0} or U = V," we need to examine the properties of invariant subspaces.

Let's consider the two cases:

Case 1: U = {0}

If U is the zero subspace, then it is trivially true that U = {0}.

Case 2: U = V

If U is the entire vector space V, then it is also true that U = V.

Now we need to consider whether there can be any other nontrivial invariant subspaces besides {0} and V.

To disprove the statement, we need to find a counterexample where U is a nontrivial invariant subspace of V.

Consider the following counterexample:

Let V be a two-dimensional vector space spanned by the basis vectors {v₁, v₂}. Let U be a subspace of V spanned by only one of the basis vectors, say U = span{v₁}.

Now, let's define a linear operator T on V such that T(v₁) = v₁ and T(v₂) = 0.

It is clear that U is invariant under the linear operator T since T(v₁) ∈ U for any v₁ ∈ U.

However, U ≠ {0} and U ≠ V in this case. Therefore, the statement "If U is invariant under every linear operator on V, then U = {0} or U = V" is false.

Hence, we have disproven the statement by providing a counterexample.

The cost of carpeting the entrance hall is $3103. To compute the cost of carpeting the entrance hall, we need to find the area of the sector and then calculate the cost based on the given price per square yard.

Convert the radius from feet to yards:

The radius is given as 22' 6", which is equal to 22 + 6/12 = 22.5 feet.

Since 1 yard is equal to 3 feet, the radius in yards is 22.5 ft / 3 = 7.5 yards.

Calculate the area of the sector:

The formula for the area of a sector is A = (θ/360) * π * r^2, where θ is the central angle and r is the radius.

In this case, the central angle is 118.5° and the radius is 7.5 yards.

A = (118.5° / 360°) * π * (7.5 yards)^2

A = (0.3292) * 3.1416 * (7.5 yards)^2

A = 0.3292 * 3.1416 * 56.25 square yards

A = 55.557 square yards (rounded to 3 decimal places)

Calculate the carpeting cost:

The cost of carpeting per square yard is $46.50. However, we need to account for an additional 20% for waste.

Total area including waste = Area + (20% of Area)

Total area including waste = 55.557 square yards + (0.20 * 55.557 square yards)

Total area including waste = 55.557 square yards + 11.1114 square yards

Total area including waste = 66.6684 square yards (rounded to 4 decimal places)

Cost = Total area including waste * Price per square yard

Cost = 66.6684 square yards * $46.50 per square yard

Cost = $3102.7628 (rounded to 4 decimal places)

Rounding the cost to the nearest dollar, the final answer is $3103.

Therefore, the cost of carpeting the entrance hall is $3103.

(a) To show that |f(x) - f(y)| ≤ M |x - y| for all x,y ∈ (a,b), we can use the Mean Value Theorem (MVT).

Let c be a point between x and y, such that x < c < y. Then, by MVT, we have:

f(x) - f(y) = f'(c)(x-y)

Since |f'(c)| ≤ M for all c ∈ (a,b), we have:

|f(x) - f(y)| = |f'(c)||x-y| ≤ M|x-y|

Thus, we have shown that |f(x) - f(y)| ≤ M |x - y| for all x,y ∈ (a,b).

(b) An example of such a function is the absolute value function on the interval (-1, 1):

f(x) = |x|

It is not differentiable at x = 0. However, for any x,y ∈ (-1,1), we have:

|f(x) - f(y)| = ||x| - |y|| ≤ |x - y| ≤ 1|x - y|

So, we have |f(x) - f(y)| ≤ M|x - y| with M = 1.

a)  The correct answer is "Reject H0."

b)"There is sufficient evidence to reject the Null Hypothesis and accept the alternative

a) Should H0 be rejected?:

In hypothesis testing, the decision to reject or fail to reject the null hypothesis (H0) is based on the comparison of the p-value to the predetermined significance level (alpha). In this case, the significance level is 0.1, and the obtained p-value is 0.044.

Since the p-value (0.044) is smaller than the significance level (0.1), we have enough evidence to reject the null hypothesis. Thus, the correct answer is "Reject H0."

b) What is the correct conclusion?

When we reject the null hypothesis, it means that the observed data provides sufficient evidence to support the alternative hypothesis. The alternative hypothesis typically represents the researcher's claim or the hypothesis they are trying to prove.

Therefore, the correct conclusion is "There is sufficient evidence to reject the Null Hypothesis and accept the alternative." This means that the data suggests a significant relationship, effect, or difference, depending on the context of the hypothesis test.

It's important to note that rejecting the null hypothesis does not prove the alternative hypothesis to be true. It indicates that the data supports the alternative hypothesis more than the null hypothesis. The conclusion should be interpreted within the specific context of the hypothesis being tested and the chosen significance level.

The correct answer is option c: 2 or 0. The function y = x² - 6x³ - 10x² + 14x - 8 has either 2 positive real roots or 0 positive real roots.

To determine the number of positive real roots, we can analyze the behavior of the function and its derivatives. The given function is a polynomial of degree 3, so it can have at most 3 real roots. However, the question specifically asks for positive real roots.

By examining the coefficients of the polynomial, we can see that the highest power of x is -6x³, indicating that the function has a negative leading coefficient. This means that the graph of the function opens downward.

To find the number of positive real roots, we need to consider the sign changes in the function. By analyzing the signs of the coefficients and evaluating the function at different points, we can observe that there can be at most 2 sign changes in the function. This implies that there can be either 2 positive real roots or 0 positive real roots.

Therefore, the correct answer is option c: 2 or 0.

3. There are 444 integers from 1 through 1,000 that are neither multiples of 2 nor multiples of 9.

According to the inclusion/exclusion principle, the number of integers from 1 through 1,000 that are multiples of 2 or 9 can be calculated as follows:

N(A ∪ B) = N(A) + N(B) - N(A ∩ B)

N(A ∪ B) = 500 + 111 - 55

N(A ∪ B) = 556

The probability that an integer chosen from 1 through 1,000 will be:

P(multiple of 2 or 9) = N(A ∪ B) / N(S)

where N(S) is the total number of integers from 1 to 1,000.

P(multiple of 2 or 9) = 556 / 1,000

P(multiple of 2 or 9) = 139 : 250

The number of integers from 1 through 1,000 that are neither multiples of 2 nor multiples of 9:

N(neither multiples of 2 nor 9) = N(S) - N(A ∪ B)

The value of x that satisfies the equation is 6.

We have,

To solve for M in equation 1 x M x 22! x 33! ... = 6, we need to simplify the factorial terms.

First, let's simplify 22! and 33!.

The factorial of a number n is the product of all positive integers from 1 to n.

22! = 22 x 21 x 20 x ... x 2 x 1

33! = 33 x 32 x 31 x ... x 2 x 1

Now, let's rewrite the equation:

1 x (x) x 22! x 33! ... = 6

Substituting the simplified factorial terms:

1 x (x) x (22 x 21 x 20 x ... x 2 x 1) x (33 x 32 x 31 x ... x 2 x 1) ... = 6

We can see that the product of the factorial terms will cancel out, as we have terms for both 22! and 33! in the equation.

1 x (x) = 6

To solve for x, we simply divide both sides of the equation by 1:

M = 6

To plot the first 30 terms of the sequence given by an = 1/2(an−1 + an−2) with a1 = 1 and a2 = 2, we can use a loop to calculate the values of each term and store them in a list. Starting with the initial values a1 and a2, we iterate from n = 3 to n = 30, calculating each term using the recurrence relation. Here's the Python code to accomplish this:

import matplotlib.pyplot as plt

# Initialize the first two terms

a = [1, 2]

# Calculate the remaining terms

for n in range(3, 31):

   an = 1/2 * (a[n-2] + a[n-3])

   a.append(an)

# Plot the sequence

plt.plot(range(1, 31), a, marker='o')

plt.xlabel('n')

plt.ylabel('an')

plt.title('Plot of the Sequence')

plt.show()

The resulting plot will show the values of the sequence for n = 1 to n = 30. The sequence starts with the initial values 1 and 2, and each subsequent term is calculated as the average of the previous two terms multiplied by 1/2. As n increases, the values of the sequence fluctuate and may converge or diverge depending on the initial values.

Plotting the sequence helps visualize the pattern and behavior of the terms. It allows us to observe any trends, periodicity, or convergence that may exist in the sequence. In this case, we can see the pattern of alternating values as the sequence progresses.
