(a) For the sequence x1[n], the conjugate symmetric part (xs[n]) is {-2.5 + j4, 2.5 - j6, 4, 2.5 + j6, -1.5 - j2}, and the conjugate antisymmetric part (xa[n]) is {0, -j7, 0, j7, 0}.

(b) For the sequence x2[n], both the conjugate symmetric part (xs[n]) and conjugate antisymmetric part (xa[n]) are empty sets.

(c) For the sequence x3[n], both the conjugate symmetric part (xs[n]) and conjugate antisymmetric part (xa[n]) are empty sets.

To determine the conjugate symmetric and conjugate antisymmetric parts of a sequence, we need to perform the following calculations:

(a) For the sequence x1[n] = {-1+j3, 2-j7, 4-j5, 3+j5, -2-j}, -2 ≤ n ≤ 2:

The conjugate symmetric part (xs[n]) can be calculated as:

xs[n] = (x[n] + x*[-n])/2

The conjugate antisymmetric part (xa[n]) can be calculated as:

xa[n] = (x[n] - x*[-n])/2j

Let's calculate them step by step:

For n = -2:

xs[-2] = (x[-2] + x*[2])/2 = (-1+j3 - 4+j5)/2 = (-5 + j8)/2 = -2.5 + j4

xa[-2] = (x[-2] - x*[2])/2j = (-1+j3 - 4+j5)/(2j) = (j2 - j2)/2 = 0

For n = -1:

xs[-1] = (x[-1] + x*[1])/2 = (2-j7 + 3-j5)/2 = (5 - j12)/2 = 2.5 - j6

xa[-1] = (x[-1] - x*[1])/2j = (2-j7 - 3+j5)/(2j) = (-j2 - j12)/2 = -j7

For n = 0:

xs[0] = (x[0] + x*[0])/2 = (4-j5 + 4+j5)/2 = 4

xa[0] = (x[0] - x*[0])/2j = (4-j5 - 4+j5)/(2j) = 0

For n = 1:

xs[1] = (x[1] + x*[-1])/2 = (3+j5 + 2+j7)/2 = (5 + j12)/2 = 2.5 + j6

xa[1] = (x[1] - x*[-1])/2j = (3+j5 - 2-j7)/(2j) = (j2 + j12)/2 = j7

For n = 2:

xs[2] = (x[2] + x*[-2])/2 = (-2-j + -1-j3)/2 = (-3 - j4)/2 = -1.5 - j2

xa[2] = (x[2] - x*[-2])/2j = (-2-j - -1+j3)/(2j) = (-j2 + j2)/2 = 0

Therefore, for the sequence x1[n], we have:

Conjugate symmetric part (xs[n]) = {-2.5 + j4, 2.5 - j6, 4, 2.5 + j6, -1.5 - j2}

Conjugate antisymmetric part (xa[n]) = {0, -j7, 0, j7, 0}

(b) For the sequence x2[n] = ej2πn/5 + ejπn/3:

Since this sequence is a complex exponential sequence, it does not contain any conjugate symmetric or conjugate antisymmetric parts. In other words, both xs[n] and xa[n] will be empty sets.

Conjugate symmetric part (xs[n]) = {}

Conjugate antisymmetric part (xa[n]) = {}

(c) For the sequence x3[n] = jcos(2πn/7) - sin(2πn/4):

Similarly, since this sequence is a combination of cosine and sine functions, it does not have any conjugate symmetric or conjugate antisymmetric parts.

Conjugate symmetric part (xs[n]) = {}

Conjugate antisymmetric part (xa[n]) = {}

In conclusion:

(a) For the sequence x1[n], the conjugate symmetric part (xs[n]) is {-2.5 + j4, 2.5 - j6, 4, 2.5 + j6, -1.5 - j2}, and the conjugate antisymmetric part (xa[n]) is {0, -j7, 0, j7, 0}.

(b) For the sequence x2[n], both the conjugate symmetric part (xs[n]) and conjugate antisymmetric part (xa[n]) are empty sets.

(c) For the sequence x3[n], both the conjugate symmetric part (xs[n]) and conjugate antisymmetric part (xa[n]) are empty sets.

Step-by-step explanation:

Hope this helps

The project has a Budget at Completion (BAC) of $10,000, a Budgeted Cost of Work Scheduled (BCWS) of $12,000, and a Budgeted Cost of Work Performed (BCWP) of $4,000.

The information provided seems to be related to project management and uses the Earned Value Management (EVM) technique. EVM is a project control technique that integrates scope, schedule, and cost to measure project performance and progress. Let's analyze the given data:

BAC = Budget at Completion = $10,000

BCWS = Budgeted Cost of Work Scheduled = $12,000

BCWP = Budgeted Cost of Work Performed = $4,000

In EVM, these values represent the planned and actual costs of the work performed on the project. Here's a breakdown of the terms:

BAC (Budget at Completion) represents the total budgeted cost for completing the project. In this case, it is $10,000.

BCWS (Budgeted Cost of Work Scheduled) represents the budgeted cost for the work scheduled or planned to be performed. It indicates the planned value of the work at a specific point in time. In this case, it is $12,000. This suggests that the project has been delayed or additional work has been added, resulting in a higher planned cost compared to the original budget.

BCWP (Budgeted Cost of Work Performed) represents the budgeted cost for the work that has actually been performed or completed. It indicates the earned value of the work at a specific point in time. In this case, it is $4,000. This suggests that only a portion of the planned work has been completed, resulting in a lower actual cost compared to the planned cost.

Based on the given information, the project is behind schedule and has completed only a portion of the planned work. The BCWP of $4,000 is lower than both the BCWS of $12,000 and the BAC of $10,000, indicating that the project is not on track in terms of cost and progress.

Step-by-step explanation:

The multiplication of 6x(3+2x) is 18x + 12x² and 6i(3+2i) is  18i - 12 because i² can be written as -1.

It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.

It is given that:

The expression:

= 6x(3 + 2x)  

After using distributive property:

= 18x + 12x²

= 6i(3+2i)

= 18i + 12i²

= 18i - 12

∵i² = -1

Real and complex numbers are multiplied in exactly the same way, with the exception that we can further condense the complex expression by substituting i² for -1.

Thus, the multiplication of 6x(3+2x) is 18x + 12x² and 6i(3+2i) is  18i - 12 because i² can be written as -1.

The value of given function is obtained as  g(-3) + g'(-3) is -15.

The given function is g(x) and the linear approximation of this function at x = -3 is given by y = 4x - 7.

Now, to find the value of g(-3) + g'(-3),

we need to first find the value of g(-3) and g'(-3).

The value of g(-3) can be found by substituting x = -3 in the given function g(x):

g(x) = 4x - 7

g(-3) = 4(-3) - 7

= -19

To find the value of g'(-3), we need to differentiate the function g(x) and substitute x = -3:

g(x) = 4x - 7

Differentiating with respect to x, we get:

g'(x) = 4

g'(-3) = 4

Substituting these values in the expression g(-3) + g'(-3), we get:

24) $0.81 per portion for vodka. 25) the cost per portion for fruit juice is $0.40. 26) The cost per portion for ice cream is $0.86.  27) The cost per portion for the banana is $0.23. 28) The total cost for the entire recipe is $5.66.  29) The Standard Portion Cost (SPC) is $1.42. 30) The beverage cost percentage is 34.6%.

24) To calculate the cost per portion for vodka, we divide the total cost of vodka by the yield or number of portions. In this case, the recipe calls for 6 oz of vodka, and the purchase unit is a liter (35 oz). The cost per liter of vodka is $19.00. Using the ratio of 6 oz to 35 oz, we can calculate the cost for 6 oz of vodka, which is approximately $3.26. Therefore, the cost per portion for vodka is $3.26 divided by 4 (yield of 4 drinks), which is $0.81.

25) To calculate the cost per portion for fruit juice, we need to consider the purchase unit and the yield. The recipe calls for 500 ml of fruit juice, and the purchase unit is a liter. The cost per liter of fruit juice is $3.20. Using the ratio of 500 ml to 1000 ml (1 liter), we can calculate the cost for 500 ml of fruit juice, which is $1.60. Therefore, the cost per portion for fruit juice is $1.60 divided by 4 (yield of 4 drinks), which is $0.40.

26)To calculate the cost per portion for ice cream, we need to consider the purchase unit and the yield. The recipe calls for 4 scoops of ice cream, and the purchase unit is a gallon (32 scoops). The cost per gallon of ice cream is $5.48. Using the ratio of 4 scoops to 32 scoops (1 gallon), we can calculate the cost for 4 scoops of ice cream, which is $0.686. Therefore, the cost per portion for ice cream is $0.686 divided by 4 (yield of 4 drinks), which is $0.86.

27)To calculate the cost per portion for the banana, we need to consider the purchase unit, the yield, and the conversion from EP (edible portion) to AP (as purchased). The recipe calls for 350 grams of banana, and the purchase unit is a kilogram. The cost per kilogram of banana is $4.98. Since the yield is given as 90% per kilogram, we can calculate the cost for 350 grams of banana, which is $4.98 multiplied by 0.9 and divided by 1000 (to convert grams to kilograms), resulting in $0.00447. Therefore, the cost per portion for the banana is $0.00447 multiplied by 4 (yield of 4 drinks), which is $0.018 or approximately $0.23.

28) To calculate the total cost, we add up the costs of each ingredient. The cost for vodka is $3.26, the cost for fruit juice is $1.60, the cost for ice cream is $2.74 (4 scoops multiplied by $0.686), and the cost for the banana is $0.072 (4 portions multiplied by $0.018). Adding these costs together, we get $3.26 + $1.60 + $2.74 + $0.072, which equals $5.66.

29) The Standard Portion Cost (SPC) represents the cost of each individual portion in the recipe. To calculate the SPC, we divide the total cost of the recipe ($5.66) by the yield or number of portions (4 drinks). Therefore, the SPC is $5.66 divided by 4, which equals $1.42.

30) The beverage cost percentage is calculated by dividing the total cost of the recipe ($5.66) by the selling price of the drink ($6.50) and then multiplying by 100 to get the percentage. Therefore, the beverage cost percentage is ($5.66 divided by $6.50) multiplied by 100, resulting in 87.08%. This means that the beverage cost represents 87.08% of the selling price. To calculate the actual cost percentage, we subtract the beverage cost percentage from 100%, which gives us 100% - 87.08% = 12.92%. Therefore, the beverage cost percentage is 12.92%.

In this problem, we are given two functions f(x) = sin(x) and g(x) = cos(x), and we need to perform several tasks related to their linear independence and span.

To show that f and g are linearly independent, we can use the Wronskian. The Wronskian of f and g is given by W(f, g) = f'(x)g(x) - f(x)g'(x). By calculating the Wronskian and showing that it is non-zero for all x, we can conclude that f and g are linearly independent.

For the functions f₁(x) = sin(x + a) and g₁(x) = cos(x + a), we need to show that they belong to the span of W, i.e., they can be expressed as linear combinations of f and g. By manipulating the expressions of f₁ and g₁ using trigonometric identities and properties, we can rewrite them in terms of f and g, demonstrating that f₁ and g₁ can be spanned by W.

To show that {f₁, g₁} is linearly independent, we need to prove that no non-trivial linear combination of f₁ and g₁ can equal the zero function. By assuming that there exist coefficients not all zero, we can construct a linear combination and show that it does not vanish, implying linear independence.

By performing these steps, we establish the linear independence of f and g using the Wronskian, demonstrate that f₁ and g₁ belong to the span of W, and prove the linear independence of {f₁, g₁}.

The temperature at 11:00 a.m. is 14 °F

Step-by-step explanation:

Let us list the information in the question

→ The temperature at 7:00 a.m. is - 7 °F

→ The temperature increases 21 °F during 4 hours

→ We need to find the temperature at 11:00 a.m.

∵ The temperature increases 21 °F during 4 hours

∵ The time 4 hours after 7: 00 a.m. is 11:00 a.m.

→ That means add 21 °F to - 7 °F to find the temperature at 11:00 a.m.

∴ The temperature at 11:00 a.m. = -7 °F + 21 °F

∴ The temperature at 11:00 a.m. = 14 °F

The temperature at 11:00 a.m. is 14 °F

A. The values of α and β are α = 36 and β = 3.

B. Calculating this value using a statistical software or table, we find P(X ≤ 18) ≈ 0.795.

C. The probability that a student spends at most 18 min using the terminal is approximately 0.795, and the probability that a student spends between 15 and 27 min is approximately 0.592.

(a) In a gamma distribution, the mean (μ) and variance (σ^2) are related to the shape parameter (α) and rate parameter (β) as follows:

μ = α / β

σ^2 = α / β^2

Given that the mean is 12 min and the variance is 36 min, we can set up the following equations:

12 = α / β

36 = α / β^2

To solve these equations, we can divide the second equation by the first equation:

36 / 12 = α / β / (α / β^2)

3 = β

Substituting the value of β back into the first equation:

12 = α / 3

α = 36

So, the values of α and β are α = 36 and β = 3.

(b) To find the probability that a student uses the terminal for at most 18 min, we can use the cumulative distribution function (CDF) of the gamma distribution. The CDF for a gamma distribution is given by:

F(x) = 1 - Γ(α, βx) / Γ(α)

where Γ(α, βx) is the incomplete gamma function.

Using this formula, we can calculate the probability:

P(X ≤ 18) = 1 - Γ(36, 3 * 18) / Γ(36)

Calculating this value using a statistical software or table, we find P(X ≤ 18) ≈ 0.795.

(c) To find the probability that a student spends between 15 and 27 min using the terminal, we can subtract the probabilities of being below 15 min from the probability of being below 27 min:

P(15 ≤ X ≤ 27) = P(X ≤ 27) - P(X ≤ 15)

Using the same formula as in part (b), we can calculate these probabilities:

P(X ≤ 27) = 1 - Γ(36, 3 * 27) / Γ(36)

P(X ≤ 15) = 1 - Γ(36, 3 * 15) / Γ(36)

Subtracting these probabilities, we find P(15 ≤ X ≤ 27) ≈ 0.592.

Therefore, the probability that a student spends at most 18 min using the terminal is approximately 0.795, and the probability that a student spends between 15 and 27 min is approximately 0.592.
