Step-by-step explanation:

The iota is a complex notation represented by the letter i in complex number.

iota power 2 can also be written as;

i^2

In complex number, the square root of -1 is iota. This can be expressed as;

\(\sqrt{-1} = i\)

Take the square of both sides

\((\sqrt{-1})^2 = i^2\\-1 = i^2\\Rearrange\\i^2 = -1\)

Hence the iota power 2 is equal to ​-1

The approximate total cost of manufacturing 900 yards of ribbon using left endpoints of 5 subintervals is $485.88.

To approximate the total cost, we'll use the left endpoint Riemann sum. First, we divide the interval [0,900] into 5 equal subintervals of width Δx = 900/5 = 180. Next, we evaluate the marginal cost function C'(x) at the left endpoints of each subinterval.

Using the left endpoint of the first subinterval (x = 0), C'(0) = -0.00002(0)^2 - 0.04(0) + 55 = 55 cents. Similarly, we compute C'(180) = 51.80, C'(360) = 48.20, C'(540) = 44.40, and C'(720) = 40.40 cents.

Now we can calculate the approximate total cost using the left Riemann sum formula: Δx * [C'(0) + C'(180) + C'(360) + C'(540) + C'(720)]. Plugging in the values, we get 180 * (55 + 51.80 + 48.20 + 44.40 + 40.40) = 180 * 240.80 = 43,344 cents.

Finally, we convert the total cost to dollars by dividing by 100: 43,344 / 100 = $433.44. Rounded to the nearest cent, the approximate total cost of manufacturing 900 yards of ribbon is $485.88.

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.

The percent increase in the interstate highway system from 1960 to now is 381%.

option A.

The percent increase from 16,000 km to 77,000 km is difference between the old value and new value divided by the old value expressed in 100%.

percent increase =  100% x (new value - old value) / old value

percent increase = 100% x  (77,000 - 16,000) / 16,000

percent increase = 100% x 61,000 / 16,000

percent increase = 381.25%

Step-by-step explanation:

The unknown biomolecule is a protein.

The unknown biomolecule is a protein. Benedict's test is commonly used to detect reducing sugars such as glucose, which produce a blue color. Since the color remained blue in the test, it suggests that the unknown biomolecule does not contain reducing sugars. On the other hand, the biuret test is used to detect the presence of peptide bonds, which are characteristic of proteins. When the unknown biomolecule was subjected to the biuret test, the color changed to purple, indicating the presence of peptide bonds and thus confirming that the unknown biomolecule is a protein.

Proteins are complex macromolecules composed of amino acids linked together by peptide bonds. They play crucial roles in various biological processes, serving as structural components, enzymes, antibodies, and signaling molecules, among others. Benedict's test, which relies on the reduction of copper ions by reducing sugars, is not specific for proteins. Therefore, the lack of color change indicates the absence of reducing sugars in the unknown biomolecule. However, the biuret test specifically detects peptide bonds, which are unique to proteins. The formation of a purple color in the biuret test confirms the presence of proteins in the unknown biomolecule.

The average rate of change of the function f(x)=x^3 - 9x + 8 over the interval from -6 to -4 is (a) -8. The average rate of change from -1 to 5 is (b) -2. The average rate of change from 5 to 7 is (c) 34.

To find the average rate of change, we need to calculate the difference in the function values at the endpoints of each interval and divide it by the difference in the x-values.

(a) From -6 to -4:

\(f(-6) = (-6)^3 - 9(-6) + 8 = -144 + 54 + 8 = -82 \\f(-4) = (-4)^3 - 9(-4) + 8 = -64 + 36 + 8 = -20\)

The average rate of change is (-20 - (-82))/(-4 - (-6)) = -8.

(b) From -1 to 5:

\(f(-1) = (-1)^3 - 9(-1) + 8 = -1 + 9 + 8 = 16\\f(5) = (5)^3 - 9(5) + 8 = 125 - 45 + 8 = 88\)

The average rate of change is (88 - 16)/(5 - (-1)) = -2.

(c) From 5 to 7:

\(f(5) = (5)^3 - 9(5) + 8 = 125 - 45 + 8 = 88\\f(7) = (7)^3 - 9(7) + 8 = 343 - 63 + 8 = 288\)

The average rate of change is (288 - 88)/(7 - 5) = 34.

Therefore, the average rate of change from -6 to -4 is -8, from -1 to 5 is -2, and from 5 to 7 is 34.

The vertical velocity of the string at the origin at time t would be zero, as the origin is a fixed point.

The origin is a fixed point, so it does not move. This means that the vertical velocity of the string at the origin at time t would be zero.

The origin of the string is a fixed point, meaning that it does not move. This implies that the vertical velocity of the string at the origin at time t would be zero, as the origin does not move or change its position. Since the origin is a fixed point, the vertical velocity of the string at the origin at time t would remain constant, and would be equal to zero. Thus, the vertical velocity of the string at the origin at time t would be zero.

To sustain the vector (5,5) as a subgame perfect equilibrium payoff in the repeated game G using Nash reversion, we need to determine the values of the discount factor d for which this is possible.

In the repeated game Go(8), the players have a common discount factor d ∈ (0,1). For a subgame perfect equilibrium, the players must play a Nash equilibrium strategy in every subgame.

In the given normal form game G, the Nash equilibria are (L, T) and (R, B). To sustain the vector (5,5) as a subgame perfect equilibrium payoff, the players would need to play the strategy (L, T) infinitely in every repetition of the game G.

The strategy (L, T) yields a payoff of (5,5) in the first stage of the game, but in subsequent stages, the players would have incentives to deviate from this strategy due to the possibility of higher payoffs. Therefore, it is not possible to sustain the vector (5,5) as a subgame perfect equilibrium payoff using Nash reversion, regardless of the value of the discount factor d.

Answer:

x = 18/25, y = -198/25

Step-by-step explanation:

Given the system of equations:

2x – y = 13x

-3x + 2y= -18

You can combine these two equations effectively by multiplying the first equation by 2, and adding because -2y and 2y will cancel out when added. So you will be left with only x terms

( 2x - y = 13x ) × 2

+ -3x + 2y = -18

________________

2(2x) - 3x + 2(-y) + 2y = 2(13x) - 18

4x - 3x - 2y + 2y = 26x - 18

x + 0 = 26x - 18

x = 26x - 18

________________

[Then use the properties of equality to simplify the expressions in the equation to derive the value of x]

x - x = 26x - 18 - x (subtraction property of equality)

0 = 25x - 18

0 + 18 = 25x - 18 + 18 (addition property of equality)

18 = 25x

18 / 25 = 25x / 25 (division property of equality)

18 / 25 = x

x = 18 / 25 (symmetric property of equality)

_______________

Now with the value of x, we can find the value of y by substituting the value of x into the variables of the top equation {2x – y = 13x} because this involves the simpliest steps.

Given x = 18 / 25.

2x – y = 13x → 2x – y + y = 13x + y → 2x = 13x + y → 2x – 13x = 13x + y – 13x → -11x = y → y = -11x.

Now that we know y = -11x, y = -11(18/25) which is - (11 × 18) / 25 = -198/25
