let f be a function with third derivative (4x 1)^3/2 what is the coeffecient of (x-2)^4 in the fourth degree taylor polynomial

Answers

Answer 1

The fourth-degree Taylor polynomial of f(x) is  \(27/(160 * 5^{(5/2)}).\)

How can we determine the coefficient of \((x - 2)^4\) in the fourth-degree Taylor polynomial of f(x)?

To find the coefficient of\((x - 2)^4\)in the fourth-degree Taylor polynomial of the function f(x), we need to compute the derivatives of f(x) up to the fourth derivative and evaluate them at x = 2.

Given that f(x) has the third derivative \((4x + 1)^{(3/2)}\), we can start by calculating the first four derivatives:

\(f'(x) = 3(4x + 1)^{(1/2)}\\f''(x) = 6(4x + 1)^{(-1/2)}\\f'''(x) = -12(4x + 1)^{(-3/2)}\\f''''(x) = 36(4x + 1)^{(-5/2)}\\\)

Next, we evaluate each derivative at x = 2:

\(f'(2) = 3(4(2) + 1)^{(1/2)} = 15^({1/2)} = \sqrt15\\f''(2) = 6(4(2) + 1)^{(-1/2)} = 6/\sqrt15\\f'''(2) = -12(4(2) + 1)^{(-3/2)} = -12/(15^{(3/2)})\\f''''(2) = 36(4(2) + 1)^{(-5/2)} = 36/(15^{(5/2)})\\\)

Finally, we use these values to calculate the coefficient of \((x - 2)^4\) in the fourth-degree Taylor polynomial, which corresponds to the fourth derivative:

coefficient =\(f''''(2) * (4!) / (4)^4\)

Simplifying the expression:

coefficient =\((36/(15^{(5/2)})) * 24 / 256\)

coefficient =\((9/(5^{(5/2)})) * 3 / 32\)

coefficient \(= 27/(160 * 5^{(5/2)})\)

Therefore, the coefficient of \((x - 2)^4\) in the fourth-degree Taylor polynomial of f(x) is  \(27/(160 * 5^{(5/2)}).\)

in the function below, c and d are constants. If the function contains the ordered pairs (5/4, 10/3) and (3/4, 1/3) what are the values of c and d

Answers

To find the values of c and d in the function, we need to use the two given ordered pairs. The function can be written in the form y = c(x) + d. Substituting (5/4, 10/3) and (3/4, 1/3) in the equation, we get two equations: 10/3 = c(5/4) + d and 1/3 = c(3/4) + d. Solving these two equations simultaneously, we get c = 8 and d = -7.

Therefore, the function is y = 8x - 7.
Given the function with constants c and d, and the ordered pairs (5/4, 10/3) and (3/4, 1/3), we can find the values of c and d. Since the ordered pairs are part of the function, we have two equations:
1) (5/4)c + d = 10/3
2) (3/4)c + d = 1/3
Solving these equations simultaneously, we find that c = 8 and d = -5/3. Therefore, the values of the constants c and d in the function are 8 and -5/3, respectively.

Find the 50th term of 12, 19, 26, 33,...

Answers

Answer:

355

Step-by-step explanation:

We have the sequence:

12, 19, 26, 33...

And we want to find the 50th term.

First, notice that this is an arithmetic sequence. This is because each subsequent term is 7 more than the previous term. So, this is increasing linearly.

Therefore, we can write an explicit formula for our sequence. The standard form for the explicit formula for an arithmetic sequence is:

\(x_n=a+d(n-1)\)

Where a is the initial term, d is the common difference, and n is the nth term.

We can see from our sequence that our initial term a is 12.

We also know that d is +7 because each term is 7 more than the previous term.

So, substitute 12 for a and 7 for d. This yields:

\(x_n=12+7(n-1)\)

To find the 50th term, let's substitute 50 for n:

\(x_{50}=12+7(50-1)\)

Evaluate. Subtract within the parentheses:

\(x_{50}=12+7(49)\)

Multiply:

\(x_{50}=12+343\)

Add:

\(x_{50}=355\)

So, the 50th term is 355.

And we're done!

Answer:

The pattern goes by adding 7 to the previous number to get the result.

12+7 = 19

19+7 = 26

26+7 = 33

The  

Use the formula  \(a_{n} = a_{1}+d(n-1)\)

The sequence = 7n-2

Therefore the 50th term

= 7(50)-2

= 350-2

= 348

A step change of magnitude 4 is introduced into a system having the following transfer function: X(s) / Y(s) = 10/s²+1.6s+4
Find: a) Y(t); b) Percent overshoot; c) Ultimate value of Y(t); d) Maximum value of Y(t) and e) Period of oscillation.

Answers

Transfer function of the system is:X(s)/Y(s) = 10/(s^2+1.6s+4)We need to find the following:

a) Y(t); b) Percent overshoot; c) Ultimate value of Y(t); d) Maximum value of Y(t) and e) Period of oscillation.

(a) Calculation of Y(t):The transfer function of the system isX(s)/Y(s) = 10/(s^2+1.6s+4)Now, applying the Laplace inverse on both sides,Y(s) = 10/(s^2+1.6s+4) × X(s)Taking the inverse Laplace of Y(s),y(t) = L^-1 {10/(s^2+1.6s+4) × X(s)}Using partial fraction decomposition to find the inverse Laplace of Y(s), we get:y(t) = 1.2508{ 2.22 e^(-0.8t) - 0.22 e^(-3.2t)}Therefore, the value of Y(t) is 1.2508{ 2.22 e^(-0.8t) - 0.22 e^(-3.2t)}.

(b) Calculation of percent overshoot:The transfer function of the system isX(s)/Y(s) = 10/(s^2+1.6s+4)The damping ratio (ζ) can be given asζ = 1/2 √(ζ²-4)ζ = 1/2 √(1.6²-4)ζ = 0.6For a second-order system with a damping ratio of 0.6, the percent overshoot is given as:%OS = e^(-ζπ/√(1-ζ²)) × 100%OS = e^(-0.6π/√(1-0.6²)) × 100OS = 26.12%Hence, the percent overshoot is 26.12%.

(c) Calculation of the ultimate value of Y(t):The transfer function of the system isX(s)/Y(s) = 10/(s^2+1.6s+4)For the ultimate value of Y(t), we take the limit of sY(s) as s tends to 0.The value of Y(s) is given as:Y(s) = 10/(s^2+1.6s+4) × X(s)On simplifying the above equation, we get:sY(s) + 1.6 Y(s) + 4 Y(s) = 10 X(s)Now, taking the limit of sY(s) as s approaches 0,sY(s) = lim s→0 sY(s) = 0Therefore, 1.6 Y(s) + 4 Y(s) = 10 X(s)Taking the limit of Y(s) as s approaches 0,0 = 10 X(0)Y(0) = 2.5Hence, the ultimate value of Y(t) is 2.5.

(d) Calculation of the maximum value of Y(t):The maximum value of Y(t) is given as:Ymax = 2.5 + (1+ζ²)^0.5 e^(-ζπ/√(1-ζ²)) / (ζ√(1-ζ²))The value of ζ is 0.6Hence, substituting the value of ζ in the above equation, we get:Ymax = 2.5 + (1+0.6²)^0.5 e^(-0.6π/√(1-0.6²)) / (0.6√(1-0.6²))Ymax = 3.129

(e) Calculation of the period of oscillation: The period of oscillation is given as:T = 2π / ωnWhere,ωn = √(1-ζ²) / (2ζ)Therefore,ωn = √(1-0.6²) / (2 × 0.6)ωn = 1.302Therefore,T = 2π / ωnT = 4.830sHence, the period of oscillation is 4.830s.

Suppose Anil won £100 in the lottery and can choose to split it with his friend Bala. If Anil’s preferences are u(A,B) = min{2A, B} (where A = lottery money that Anil keeps, B = lottery money that Anil gives to Bala), then it is optimal for Anil to give Bala one-third of the lottery money T/F

Answers

False. It is not optimal for Anil to give Bala one-third of the lottery money (£33.33). According to Anil's preferences, his utility function is given by u(A,B) = min{2A, B}.

This function implies that Anil values his own money (A) more than the money he gives to Bala (B). By giving Bala one-third of the money, Anil would keep only £66.67 for himself, which is less than what he could potentially keep if he gave Bala a smaller amount. To maximize his own utility, Anil should give Bala the minimum amount possible, which in this case would be zero.

Anil's utility function indicates that he values his own money (A) twice as much as the money he gives to Bala (B). By maximizing his utility, Anil would want to keep as much money for himself as possible, while still giving Bala some amount of money. In this case, Anil can keep £100 for himself, which is the maximum amount possible, while giving Bala £0.

This division of money maximizes Anil's utility according to his preferences. Therefore, it is not optimal for Anil to give Bala one-third of the lottery money; instead, he should give Bala the minimum amount of £0 to maximize his own utility.

Answers

The cost of walking this guest is $190.

The cost of walking the guest can be calculated by adding up the expenses incurred by the hotel.

The guest was walked to another hotel that charged a room rate of $150. Therefore, the hotel incurred a cost of $150 for the room.

In addition to the room cost, the hotel also paid for the guest's Uber ride to the new hotel, which was $15.

Furthermore, the overbooked hotel gave the guest a gift card worth $25. Although the gift card does not directly represent an expense, it can be considered as an opportunity cost for the hotel, as they could have used that money to cover other costs.

Therefore, the total cost incurred by the hotel for walking the guest is:

$150 (room cost) + $15 (Uber cost) + $25 (gift card cost) = $190

The adjustments may involve balancing the nutrient composition, addressing amino acid imbalances, increasing calcium and phosphorus levels, ensuring adequate sodium content, and considering different feed forms.

Based on the given information, the poultry layer ration contains the following ingredients:

- Maize: 612 g/kg

- Barley: 158 g/kg

- Molasses: 20 g/kg

- Cottonseed Meal: 100 g/kg

- Fish Meal: 100 g/kg

- Dicalcium Phosphate: 10 g/kg

The ration also provides the total requirements for various nutrients, such as metabolizable energy (ME), crude protein (CP), lysine (LYS), methionine (MET), phenylalanine (PHE), tryptophan (TRP), calcium (Ca), phosphorus (P), and sodium (Na).

The complaints regarding funny-looking and terrible-tasting eggs, along with a slight decrease in feed intake, suggest that there may be issues with the ration that are impacting egg quality and palatability. Based on this information, here are some possible explanations and recommendations:

1. Imbalanced Nutrient Composition: The nutrient content of the ration may be imbalanced, leading to poor egg quality and taste. It's important to ensure that the nutrient levels are appropriate for poultry layer production. A consultation with a poultry nutritionist or veterinarian would be beneficial to determine the correct nutrient ratios for the ration.

2. Inadequate Amino Acid Balance: The amino acid balance in the ration is crucial for egg production and quality. The levels of lysine (LYS), methionine (MET), phenylalanine (PHE), and tryptophan (TRP) should be carefully evaluated. Supplementing the ration with specific amino acids or adjusting the protein sources may help improve egg quality.

3. Insufficient Calcium and Phosphorus: Calcium and phosphorus are essential for eggshell formation. The provided ration appears to have low levels of calcium (Ca) and phosphorus (P), which can lead to weak or abnormal eggshells. Increasing the levels of these minerals, either by adjusting the ratio of existing ingredients or incorporating additional calcium and phosphorus sources, may help address this issue.

4. Sodium Imbalance: Sodium (Na) is required for various physiological functions, including egg production. However, the ration seems to have a low sodium content. Ensuring adequate sodium levels in the diet might help stimulate feed intake and improve overall performance.

5. Texture and Processing: The ration is described as a coarsely ground mash. The texture and processing of the feed can influence how well the birds consume and utilize the ration. It might be worth exploring different feed forms (e.g., pellets or crumbles) to improve intake and digestion.

Overall, to alleviate the reported issues with egg quality and palatability, it is recommended to consult with a poultry nutritionist or veterinarian to reformulate the ration. The adjustments may involve balancing the nutrient composition, addressing amino acid imbalances, increasing calcium and phosphorus levels, ensuring adequate sodium content, and considering different feed forms.

you have 12 marbles and a scale. one marble is heavier than the others. you can only use the scale three times. how can you find the heavier marble? (you cannot feel them in your hands that is cheating)

Answers

You can weigh 4 marbles against each other first, then if none are heavier, weigh 3 of the remaining marbles against each other, and if none of those are heavier, weigh the last two marbles against each other to find the heavier one.

What is weight of an object?

An object's power of attraction toward the Earth is measured by its weight. It is the result of multiplying the object's mass by the acceleration caused by gravity.

What instrument is used  to weigh an objects?

A scale or balance is a tool used to determine mass or weight. These are also referred to as weight scales, mass scales, weight balances, and mass balances.

To weigh the 12 marbles and find out the heavier one,

Take 4 marbles and weigh them against each other. If one of them is heavier, you have found the heavier marble. If they all weigh the same, go to step 2.Take 3 of the remaining marbles and weigh them against each other. If one of them is heavier, you have found the heavier marble. If they all weigh the same, go to step 3.Take the remaining 2 marbles and weigh them against each other. The heavier one is the heavier marble.

This solution will always work because at each step, you are halving the number of marbles you need to check, so you will always be able to find the heavier marble in 3 weighings or less.

George is required to produce 500 frames for an art gallery. He spent $100 on the wood required for all these frames. He also spent $50 in polishing all the final frames. He rented two floors of an art gallery for about $700. What selling price should George charge the art gallery if he wants to break even?

Answers

Answer:

George should charge 1.70$ for each frame to break-even.

Step-by-step explanation:

Variable cost for the frames:

Wood + polishing = $100 + $50 = $150

Variable cost per frame would be:

$150/ 500 = $0.30

The fixed cost of the operation is $700.

George has to make 500 frames.

Fixed cost / (Selling price per unit – variable cost per unit) = 500

$700 / (Selling price per unit - $0.30) = 500

700 = 500 (Selling price per unit – 0.30)

700 = 500 * Selling price – 500 * 0.3

700 = 500 * Selling price – 150

(700 + 150) / 500 = Selling price

850 / 500 = 1.7

a) Contribution (objective value) = $132.14

b) The firm earns $132.14 at the optimal solution.

c) An additional hour of time available for the third machine is worth $0.14 to the firm.

Samuel made 31 out of 40 field goals during football practice. What percent of the field goals did Samuel make?

Answers

The percent of the field goals did Samuel make will be 77.5%.

How to calculate the percentage?

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100. The percentage therefore refers to a component per hundred. Per 100 is what the word percent means. It is represented by %.

Samuel made 31 out of 40 field goals during football practice. The percent of the field goals did Samuel make will be:

= 31 / 40 × 100

= 77.5%

The percentage is 77.5%.
