The total time for all the jobs is 19 + 13 + 13 + 21 + 24 = 90 hours.
Johnson's Rule is a sequencing method used to determine the order in which jobs should be processed in a two-step system. It is based on the processing times of each job in the two steps. In this case, the processing times for each job in operation 2 at Job Process 1 and Process 2 are given as follows:
Job A: Process 1 - 12 hours, Process 2 - 9 hours
Job B: Process 1 - 8 hours, Process 2 - 11 hours
Job C: Process 1 - 7 hours, Process 2 - 6 hours
Job D: Process 1 - 10 hours, Process 2 - 14 hours
Job E: Process 1 - 5 hours, Process 2 - 8 hours
To determine the order, we first need to calculate the total time for each job by adding the processing times of both steps. Then, we select the job with the shortest total time and schedule it first. Continuing this process, we schedule the jobs in the order of their total times.
Calculating the total times for each job:
Job A: 12 + 9 = 21 hours
Job B: 8 + 11 = 19 hours
Job C: 7 + 6 = 13 hours
Job D: 10 + 14 = 24 hours
Job E: 5 + 8 = 13 hours
The job with the shortest total time is Job B (19 hours), so it is scheduled first. Then, we schedule Job C (13 hours) since it has the next shortest total time. After that, we schedule Job E (13 hours) and Job A (21 hours). Finally, we schedule Job D (24 hours).
Therefore, the order in which the jobs would complete processing on operation 2 at Job Process 1 and Process 2, when using Johnson's Rule, is:
Job B, Job C, Job E, Job A, Job D
The total time for all the jobs is 19 + 13 + 13 + 21 + 24 = 90 hours.
Therefore, the correct answer is not provided in the options given.

Obtain a differential equation by eliminating the arbitrary constant. y = cx + c² + 1
A y=xy' + (y')²+1
B y=xy' + (y') 2
©y'= y' = cx
D y' =xy" + (y') 2
Obtain a differential equation by eliminating the arbitrary constant. y = cx + c² + 1. the correct option is A) y = xy' + (y')^2 + 1.
To eliminate the arbitrary constant c and obtain a differential equation for y = cx + c^2 + 1, we need to differentiate both sides of the equation with respect to x:
dy/dx = c + 2c(dc/dx) ...(1)
Now, differentiating again with respect to x, we get:
d^2y/dx^2 = 2c(d^2c/dx^2) + 2(dc/dx)^2
Substituting dc/dx = (dy/dx - c)/2c from equation (1), we get:
d^2y/dx^2 = (dy/dx - c)(d/dx)[(dy/dx - c)/c]
Simplifying, we get:
d^2y/dx^2 = (dy/dx)^2/c - (d/dx)(dy/dx)/c
Multiplying both sides of the equation by c^2, we get:
c^2(d^2y/dx^2) = c(dy/dx)^2 - c(d/dx)(dy/dx)
Substituting y = cx + c^2 + 1, we get:
c^2(d^2/dx^2)(cx + c^2 + 1) = c(dy/dx)^2 - c(d/dx)(dy/dx)
Simplifying, we get:
c^3x'' + c^2 = c(dy/dx)^2 - c(d/dx)(dy/dx)
Dividing both sides by c, we get:
c^2x'' + c = (dy/dx)^2 - (d/dx)(dy/dx)
Substituting dc/dx = (dy/dx - c)/2c from equation (1), we get:
c^2x'' + c = (dy/dx)^2 - (1/2)(dy/dx)^2 + (c/2)(d/dx)(dy/dx)
Simplifying, we get:
c^2x'' + c = (1/2)(dy/dx)^2 + (c/2)(d/dx)(dy/dx)
Finally, substituting dc/dx = (dy/dx - c)/2c and simplifying, we arrive at the differential equation:
y' = xy'' + (y')^2 + 1
Therefore, the correct option is A) y = xy' + (y')^2 + 1.

Part C2 - Oxidation with Benedict's Solution Which of the two substances can be oxidized? What is the functional group for that substance? Write a balanced equation for the oxidation reaction with chr
Benedict's solution is commonly used to test for the presence of reducing sugars, such as glucose and fructose. In this test, Benedict's solution is mixed with the substance to be tested and heated. If a reducing sugar is present, it will undergo oxidation and reduce the copper(II) ions in Benedict's solution to copper(I) oxide, which precipitates as a red or orange precipitate.
To determine which of the two substances can be oxidized with Benedict's solution, we need to know the nature of the functional group present in each substance. Without this information, it is difficult to determine the substance's reactivity with Benedict's solution.
However, if we assume that both substances are monosaccharides, such as glucose and fructose, then they both contain an aldehyde functional group (CHO). In this case, both substances can be oxidized by Benedict's solution. The aldehyde group is oxidized to a carboxylic acid, resulting in the reduction of copper(II) ions to copper(I) oxide.
The balanced equation for the oxidation reaction of a monosaccharide with Benedict's solution can be represented as follows:
C₆H₁₂O₆ (monosaccharide) + 2Cu₂+ (Benedict's solution) + 5OH- (Benedict's solution) → Cu₂O (copper(I) oxide, precipitate) + C₆H₁₂O₇ (carboxylic acid) + H₂O
It is important to note that without specific information about the substances involved, this is a generalized explanation assuming they are monosaccharides. The reactivity with Benedict's solution may vary depending on the functional groups present in the actual substances.

The Flemings secured a bank Ioan of $320,000 to help finance the purchase of a house. The bank charges interest at a rate of 3%/year on the unpaid balance, and interest computations are made at the end of each month. The Flemings have agreed to repay the in equal monthly installments over 25 years. What should be the size of each repayment if the loan is to be amortized at the end of the term? (Round your answer to the nearest cent.)
The size of each repayment should be $1,746.38 if the loan is to be amortized at the end of the term.
Given: Loan amount = $320,000
Annual interest rate = 3%
Tenure = 25 years = 25 × 12 = 300 months
Annuity pay = Monthly payment amount to repay the loan each month
Formula used: The formula to calculate the monthly payment amount (Annuity pay) to repay a loan amount with interest over a period of time is given below.
P = (Pr) / [1 – (1 + r)-n]
where P is the monthly payment,
r is the monthly interest rate (annual interest rate / 12),
n is the total number of payments (number of years × 12), and
P is the principal or the loan amount.
The interest rate of 3% per year is charged on the unpaid balance. So, the monthly interest rate, r is given by;
r = (3 / 100) / 12 = 0.0025 And the total number of payments, n is given by n = 25 × 12 = 300
Substituting the given values of P, r, and n in the formula to calculate the monthly payment amount to repay the loan each month.
320000 = (P * (0.0025 * (1 + 0.0025)^300)) / ((1 + 0.0025)^300 - 1)
320000 = (P * 0.0025 * 1.0025^300) / (1.0025^300 - 1)
(320000 * (1.0025^300 - 1)) / (0.0025 * 1.0025^300) = P
Monthly payment amount to repay the loan each month = $1,746.38

For the given function, find (a) the equation of the secant line through the points where x has the given values and (b) the equation of the tangent line when x has the first value. y=f(x)=x^2+x;x=−4,x=−1
The equation of the tangent line passing through the point (-4, 12) with slope -7: y = -7x - 16.
We are given the function: y = f(x) = x² + x and two values of x:
x₁ = -4 and x₂ = -1.
We are required to find:(a) the equation of the secant line through the points where x has the given values (b) the equation of the tangent line when x has the first value (i.e., x = -4).
a) Equation of secant line passing through points (-4, f(-4)) and (-1, f(-1))
Let's first find the values of y at these two points:
When x = -4,
y = f(-4) = (-4)² + (-4)
= 16 - 4
= 12
When x = -1,
y = f(-1) = (-1)² + (-1)
= 1 - 1
= 0
Therefore, the two points are (-4, 12) and (-1, 0).
Now, we can use the slope formula to find the slope of the secant line through these points:
m = (y₂ - y₁) / (x₂ - x₁)
= (0 - 12) / (-1 - (-4))
= -4
The slope of the secant line is -4.
Let's use the point-slope form of the line to write the equation of the secant line passing through these two points:
y - y₁ = m(x - x₁)
y - 12 = -4(x + 4)
y - 12 = -4x - 16
y = -4x - 4
b) Equation of the tangent line when x = -4
To find the equation of the tangent line when x = -4, we need to find the slope of the tangent line at x = -4 and a point on the tangent line.
Let's first find the slope of the tangent line at x = -4.
To do that, we need to find the derivative of the function:
y = f(x) = x² + x
(dy/dx) = 2x + 1
At x = -4, the slope of the tangent line is:
dy/dx|_(x=-4)
= 2(-4) + 1
= -7
The slope of the tangent line is -7.
To find a point on the tangent line, we need to use the point (-4, f(-4)) = (-4, 12) that we found earlier.
Let's use the point-slope form of the line to find the equation of the tangent line passing through the point (-4, 12) with slope -7:
y - y₁ = m(x - x₁)
y - 12 = -7(x + 4)
y - 12 = -7x - 28

Producers of a certain brand of refrigerator will make 1000 refrigerators available when the unit price is $ 410 . At a unit price of $ 450,5000 refrigerators will be marketed. Find the e
The following is the given data for the brand of refrigerator.
Let "x" be the unit price of the refrigerator in dollars, and "y" be the number of refrigerators produced.
Suppose that the producers of a certain brand of the refrigerator make 1000 refrigerators available when the unit price is $410.
This implies that:
y = 1000x = 410
When the unit price of the refrigerator is $450, 5000 refrigerators will be marketed.
This implies that:
y = 5000x = 450
To find the equation of the line that represents the relationship between price and quantity, we need to solve the system of equations for x and y:
1000x = 410
5000x = 450
We can solve the first equation for x as follows:
x = 410/1000 = 0.41
For the second equation, we can solve for x as follows:
x = 450/5000 = 0.09
The slope of the line that represents the relationship between price and quantity is given by:
m = (y2 - y1)/(x2 - x1)
Where (x1, y1) = (0.41, 1000) and (x2, y2) = (0.09, 5000)
m = (5000 - 1000)/(0.09 - 0.41) = -10000
Therefore, the equation of the line that represents the relationship between price and quantity is:
y - y1 = m(x - x1)
Substituting m, x1, and y1 into the equation, we get:
y - 1000 = -10000(x - 0.41)
Simplifying the equation:
y - 1000 = -10000x + 4100
y = -10000x + 5100
This is the equation of the line that represents the relationship between price and quantity.
