A firm faces the following costs: total cost of capital = $2,000; price paid for labor = $12 per labor unit; and price paid for raw materials = $4 per raw-material unit.

Instructions: In parts a and b, round your answers to 2 decimal places. In part c, enter your answer as a whole number.

a. Suppose the firm can produce 6,000 units of output this year by combining its fixed capital with 100 units of labor and 450 units of raw materials. What are the total cost and average total cost of producing the 6,000 units of output?

TC=

ATC=

b. Now assume the firm improves its production process so that it can produce 7,000 units of output this year by combining its fixed capital with 100 units of labor and 450 units of raw materials. What are the total cost and average total cost of producing the 7,000 units of output?

TC=

ATC=

c. If units of output can always be sold for $1 each, then by how much does the firm’s profit increase after it improves its production process?

2-Give recipe example for electroplating Cu, Au, and Ni. Explain how to prepare the electroplating solution.

Discuss the importance of having comparable populations underlying comparisons of experimental and non-experimental estimates.

A simple generator has a square armature 7.0cm on a side. The armature has 95 turns of 0.59-mm-diameter copper wire and rotates in a 0.800-T magnetic field. The generator is used to power a lightbulb rated at 12.0 V and 25.0 W. At what rate should the generator rotate to provide 12.0 V to the bulb? Consider the resistance of the wire on the armature.

Find the critical value of t for each of the following:

Please show work and explain.

a. 1-α = 0.95, n=21

b. 1-α = 0.99, n=21

c. 1-α = 0.90, n=32

d. 1-α = 0.99, n=65

Consider the work-energy theorem relating work done on an object and its change in kinetic energy. What is the formula? Explain in your own words what this formula gives you. Create an example. Include a graphical or picture representation that illustrates what all the variables are. Then exemplify the use of the formula with a simple problem of your own creation. The problem should be stated in words first. Every variable should have a well defined value with appropriate units. Finally, solve your problem.

A person walks into a room and switches on the ceiling fan. The fan accelerates with constant angular acceleration for 18s until it reaches its operating angular speed of 2.0rotations/s - after that its speed remains constant as long as the switch is "on". The person stays in the room for a short time; then, 5.5 minutes after turning the fan on, she switches it off again and leaves the room. The fan now decelerates with constant angular acceleration, taking 2.4 minutes to come to rest.

What is the total number of revolutions made by the fan, from the time it was turned on until the time it stopped?

Express your answer using two significant figures.

How did the geography and environment of New England influence British settlement and commercial patterns? In what ways did the New England colonies differ from their middle and southern colonial neighbors?

Write a program using MARIE’s assembly language. The program consists of a main program and a subroutine. It uses the subroutine to process a given number. If the value of the number is negative, the value will be replaced with zero and returned. Otherwise, the value is doubled and returned. Then, in the main program, it calls the subroutine to process for X = -3 and saves the value after the processing.

Write a fragment of code that uses two existing arrays of doubles, a and b, creates a third array c, and assigns each element of c to the average of the corresponding elements of a and b. You may assume that the arrays a and b are the same length. (java)
