Component 3 must be started on day 197 to meet the delivery date of day 200.

To illustrate the backward schedule, we need to start from the delivery date (day 200) and work our way backward, taking into account the lead times and dependencies of each operation.

(a) Backward schedule:

Operation    |  Work Center  |  Time (hours)  |  Start Day

--------------------------------------------------------

Final Assembly |   Work Center 1  |        1       |     200

Sub-assembly 1 |   Work Center 2  |        2       |     199

Component 4     |   Work Center 3  |        3       |     197

Component 2     |   Work Center 4  |        4       |     196

Component 3     |   Work Center 5  |        3       |     ????

(b) To identify when component 3 must be started to meet the delivery date, we need to consider its dependencies and lead times.

From the backward schedule, we see that component 3 is required for sub-assembly 1, which is scheduled to start on day 199. The time required for sub-assembly 1 is 2 hours, which means it should be completed by the end of day 199.

Since component 3 is needed for sub-assembly 1, we can conclude that component 3 must be started at least 2 hours before the start of sub-assembly 1. Therefore, component 3 should be started on day 199 - 2 = 197 to ensure it is completed and ready for sub-assembly 1.

Hence, component 3 must be started on day 197 to meet the delivery date of day 200.

Step-by-step explanation:

The x-values between 0≤x<2π where the tangent line of f(x) = 2sinx - x is horizontal are π/3 and 5π/3.

The tangent line of a function is horizontal when the derivative of the function is equal to zero. To find the x-values where the tangent line of the function f(x) = 2sinx - x is horizontal, we need to find the critical points of the function.

1: Find the derivative of f(x) using the chain rule.
f'(x) = 2cosx - 1

2: Set the derivative equal to zero and solve for x.
2cosx - 1 = 0
2cosx = 1
cosx = 1/2

3: Find the values of x between 0 and 2π that satisfy the equation cos x = 1/2. These values are where the tangent line of the function is horizontal.

The cosine function has a value of 1/2 at two points within 0 to 2π: x = π/3 and x = 5π/3.

Therefore, the x-values between 0≤x<2π where the tangent line of f(x) = 2sinx - x is horizontal are π/3 and 5π/3

Answer: C. 00:00 $927; Vince wrote the wrong number to represent the interest rate.

Step-by-step explanation:

Given that:

Amount borrowed (p) = 900

Simple interest (r) = 1.5% = 0.015

Time (t) = 2 years

Amount he'll pay back (A) :

A = P(1 + rt)

A = 900(1 + 0.015(2))

A = 900(1 + 0.03)

A = 900(1.03)

A = $927

Answer:

-95

Step-by-step explanation:

(4 - m) / 9 = 11

Multiply both sides by 9:

4 - m = 99

Subtract both sides by 4:

-m = 95

Multiply both sides by -1:

m = -95

Answer:

-63

Step-by-step explanation:

4 - M = 11

---

9

Bring the 4 to the opposite side of the variable ( bring the 4 to the other side of the = sign where it shows 11 or a different number with no variable. basically if you get a question problem for math like this, and when you see a variable aka a letter, move it to the other side where it doesn't have a letter, move it with the = sign then add or subtract. if the number that your moving away from the variable is positive, you subtract making it negative... but if you have a negative number, do adding instead. )

4 - 11 = -7

subtract and then you muliply

M

--- = -7

9

once you mulipled -7 x 9

your answer should be

M = -63

Let's calculate the total cost of all the items purchased by the computer club:

Cost of 14 portfolios = 14 * $24.59

Cost of 14 binders = 14 * $12.92

Cost of 14 school sweatshirts = 14 * $14.00

Cost of 14 music cases = 14 * $1.25

Cost of 14 phone cases = 14 * $1.99

Cost of 14 mouse pads = 14 * $2.14

Total cost of all items = Cost of 14 portfolios + Cost of 14 binders + Cost of 14 school sweatshirts + Cost of 14 music cases + Cost of 14 phone cases + Cost of 14 mouse pads

Plugging in the given values:

Total cost of all items = (14 * $24.59) + (14 * $12.92) + (14 * $14.00) + (14 * $1.25) + (14 * $1.99) + (14 * $2.14)

Now, the computer club will pay for 40% of the total cost. To calculate this, we can multiply the total cost by 40% (or 0.40):

Club's payment = 0.40 * Total cost of all items

The remaining cost will be divided equally among the 14 members:

Remaining cost per member = (Total cost of all items - Club's payment) / 14

Plugging in the values and calculating:

Club's payment = 0.40 * ((14 * $24.59) + (14 * $12.92) + (14 * $14.00) + (14 * $1.25) + (14 * $1.99) + (14 * $2.14))

Remaining cost per member = ((14 * $24.59) + (14 * $12.92) + (14 * $14.00) + (14 * $1.25) + (14 * $1.99) + (14 * $2.14) - Club's payment) / 14

So, each member of the computer club will owe the calculated value for "Remaining cost per member".

The specific details of the reaction mechanism and rate constants will vary depending on the actual methane-air reaction being studied. Make sure to consult relevant literature or resources to obtain accurate and up-to-date information for your specific case.

To create a species concentration plot as a function of inlet temperature for a well-stirred reactor with an equivalence ratio of 0.5, we will focus on the methane-air reaction at a pressure of 10 atm.

1. Start by gathering the necessary information and data related to the methane-air reaction at the given conditions. This includes the reaction mechanism and rate constants, as well as the initial concentrations of the species involved.

2. Determine the range of inlet temperatures for which you want to create the concentration plot. Let's assume a range from 100°C to 500°C.

3. Divide this temperature range into several points or intervals at which you will calculate the species concentrations. For example, you can choose intervals of 50°C, resulting in 9 points (100°C, 150°C, 200°C, ..., 500°C).

4. For each temperature point, set up a system of coupled ordinary differential equations (ODEs) to describe the reaction kinetics. These ODEs will involve the rate of change of each species' concentration with respect to time.

5. Solve the system of ODEs using appropriate numerical methods, such as the Runge-Kutta method or the Euler method. This will give you the species concentrations as a function of time for each temperature point.

6. Plot the concentration of each species against the inlet temperature. The x-axis represents the temperature, and the y-axis represents the concentration. You can choose to plot all the species on a single graph or create separate graphs for each species.

7. Label the axes and provide a clear legend or key to identify the different species.

8. Analyze the resulting concentration plot to understand the effect of temperature on the species concentrations. You can look for trends, such as the formation or depletion of certain species at specific temperatures.

Remember, the specific details of the reaction mechanism and rate constants will vary depending on the actual methane-air reaction being studied. Make sure to consult relevant literature or resources to obtain accurate and up-to-date information for your specific case.

Please note that this answer provides a general guideline for creating a species concentration plot as a function of inlet temperature. The actual implementation may require more detailed considerations and calculations based on the specific reaction system and conditions involved.

To create a species concentration plot as a function of inlet temperature for the well-stirred reactor with an equivalence ratio of 0.5 in the Methane-Air reaction at 10 atm, you would calculate the stoichiometric ratio, determine the initial concentrations, vary the temperature while keeping the ratio constant, and plot the concentrations of methane, oxygen, carbon dioxide, and water.

To create a species concentration plot as a function of inlet temperature for the well-stirred reactor with an equivalence ratio of 0.5 in the Methane-Air reaction at 10 atm, you would follow these steps:

1. Start by determining the species involved in the reaction. In this case, we have methane (CH4) and air, which mainly consists of oxygen (O2) and nitrogen (N2).

2. Calculate the stoichiometric ratio of methane to oxygen in the reaction. The reaction equation for methane combustion is:
  CH4 + 2O2 -> CO2 + 2H2O

  Since the equivalence ratio is 0.5, the ratio of methane to oxygen will be half of the stoichiometric ratio. Therefore, the stoichiometric ratio is 1:2, and the ratio for this reaction will be 1:1.

3. Determine the initial concentration of methane and oxygen. The concentration of methane can be given in units like mol/L or ppm (parts per million), while the concentration of oxygen is typically given in mole fraction or volume fraction.

4. Vary the inlet temperature while keeping the equivalence ratio constant at 0.5. Start with a low temperature and gradually increase it. For each temperature, calculate the species concentrations using a suitable software or model, considering the reaction kinetics and the pressure of 10 atm.

5. Plot the species concentration of methane, oxygen, carbon dioxide, and water as a function of inlet temperature. The x-axis represents the inlet temperature, while the y-axis represents the concentration of each species.

Remember to label the axes and provide a legend for the species in the plot. This plot will provide insights into how the species concentrations change with varying temperatures in the well-stirred reactor under the given conditions.

The perimeter of the rectangle is_52cm___ centimeters.

To find the perimeter of the rectangle, we need to know the lengths of its sides.

However, we only have information about the area and one side length. Without additional information, we cannot determine the lengths of the other sides or calculate the perimeter.

If we assume that the rectangle is a square, with one side length of 13 centimeters, then we can calculate the perimeter.

In this case, all sides of the square would be equal.

\(Perimeter $ of a square = 4 \times side length\)

So, the perimeter of the square (rectangle) would be:

\(Perimeter = 4 \times 13 cm = 52 cm\).

If we assume that the rectangle is a square, then the perimeter would be 52 centimeters.

However, if the rectangle is not a square and has different side lengths, we would need additional information to calculate the perimeter.

The only correct option about the domain and range given is;

Option A: g(-13) = 20

We are told that a function, g, has;

Domain of -20 ≤ x ≤ 5

Range of -5 ≤ g(x) ≤ 45

g(0) = -2 and g(-9) = 6

Lets look at each option to see whether it fits into the given domain and range;

a) g(-13) = 20

x = -13 is in our domain  and 20 is also in our range. Thus, g(-13) = 20 is true for g.

b) g(7) = -1

7 is not in our domain . Thus, g(7) is not possible.

c) g(-4) = -11

-11 does is not in the given range and as such, g(-4) = -11 is not true.

d) g(0) = 2

This is not true because we are told that g(0)=-2

To find the radius of the crystal ball, we can use the formula for the volume of a sphere: V = (4/3) * π * r^3, where V is the volume and r is the radius.

Given that the volume of the crystal ball is 113.14 cm³, we can solve for r:

113.14 = (4/3) * π * r^3

To find the radius, we can rearrange the equation:

r^3 = (3/4) * (113.14 / π)

r = (3/4) * (113.14 / π)^(1/3)

Using a calculator, we can evaluate the expression to find the approximate value of the radius.
