A 0.4627 g sample of pewter, containing tin, lead, copper, and zinc, was dissolved in acid. Tin was precipitated as SnO2·4H2O and removed by filtration. The resulting filtrate and washings were diluted to a total volume of 200.0 mL. A 20.00 mL aliquot of this solution was buffered, and titration of the lead, copper, and zinc in solution required 34.11 mL of 0.001500 M EDTA. Thiosulfate was used to mask the copper in a second 25.00 mL aliquot. Titration of the lead and zinc in this aliquot required 34.45 mL of the EDTA solution. Finally, cyanide was used to mask the copper and the zinc in a third 30.00 mL aliquot. Titration of the lead in this aliquot required 24.39 mL of the EDTA solution. Determine the percent composition by mass of each metal in the pewter sample.

Simone works for a group that wants to register more people to vote. She knows her team can only ask a
certain number of people at any given time since they have other obligations. She has asked you to create a
program for her team that allows the user to type in how many people they want to ask at one time (the
duration of the current program run). The program will then ask that many people (see sample run). If a
person answers y, his or her name is added to a registration list (a file) and the current registration list is
output to screen. If they answer n, Ok is output to screen and the program continues. Once at least 10 people
have been registered, whenever the program is opened the phrase Target Reached! Exiting… should be
output to screen.
Step 1: You will be defining the following two functions (DO NOT MODIFY THE DECLARATIONS):
/*This function takes a file pointer, goes through the file and prints the file contents to screen. It returns the
number of lines in the file*/
int registered(FILE *fp)
/*This function takes a file pointer and adds a new line to the file*/
void new_register(FILE *fp)
Step 2: Use the functions you defined to make a working program.
Sample Run:

1. Star with Newton's third law: dp/dt = ΣF where p is the momentum. In space, the sum of the external forces ΣF = 0. For a rocket in space, the mass and velocity change with time as the rocket expends its fuel. Show from Newton's third law that ΔV = v ln(m/M) where m is the initial mass of the rocket, M is the final mass of the rocket after the fuel is expended, v is the rocket's exhaust velocity and ΔV is the change in the velocity for the rocket

2. Now, the rocket needs to get to escape velocity to get to the moon. Use conservation of energy to derive an expression for the escape velocity. If we start at 200km above the surface of earth, calculate the ΔV we need to escape from Earth and get to the moon.

3. Finally, use the earlier Rocket Equation calculate the fraction of the initial rocket's mass that is dedicated to fuel to make the journey from the Earth to the Moon. In this case, v is 4500 m/s.

A cubical box, open at the top, with edge length 81.0 cm, is constructed from metal plate of uniform density and negligible thickness. One of the bottom corners of the box is at 0,0,0, the base of the box is in the x-y plane and the box is the positive quadrant. What is the x coordinate of the center of mass of the box (in cm.)?

What is the y coordinate of the center of mass of the box (in cm.)?

What is the z coordinate of the center of mass of the box (in cm.)?

The programming language has to be C

The user is going to provide you with a map of rivers and grassland. Each cell on the map will be either grassland or river. Your job is to decorate this map with forks, 4 way forks, and river bends when a river bends. You will process the user's map and modify the river cells if they depict a river bend.

You will use enums to model the river, its bends, and forks. You will pattern match to replace parts of the river with bends and forks. Out of bounds regions will be considered grasslands for pattern matching simplicity.

You will use enums in this program.

You will print the integers with 1 space padding and rows will be terminated by new lines:

10 10 10
 1  2  3
 4  5  6
 7  8  9
10 10 10

Input and Output

The tiles that we use in the map are:

• 0 Grassland
• 1 River
• 2 NorthWestRiverBend
• 3 SouthWestRiverBend
• 4 NorthEastRiverBend
• 5 SouthEastRiverBend
• 6 NorthEastSouthFork
• 7 NorthWestSouthFork
• 8 WestNorthEastFork
• 9 WestSouthEastFork
• 10 FourWayFork

The user will input maps usually of 0 and 1 but they can include other tiles as well. Typically it will 0 and 1.

The user will input a map of

 0  0  0  0  0  0 
 0  1  1  1  1  0
 0  1  0  0  1  0

 0  1  0  0  1  0
 0  1  1  1  1  0
 0  0  0  0  1  0

Where 0 is grassland and 1 is river

The program will look for corners and replace them with the RiverBend pieces.

 0  4  1  1  7  0 
 0  0  0  0  1  0 

The header format is described below. $WIDTH is the number of cells wide and $HEIGHT is the number of cells tall.

P2
$WIDTH $HEIGHT

The individual cells are whitespace seperated for input. Ignore whitespace and newlines for the cells.

The output format is strict, each row ends in a newline and there is 1 space padding for all integers cells printed.

Please review the q1a-test?-input.txt files for more examples

Patterns

• Examples of No change

 0  0  0         0  0  0
 0  0  0    ->   0  0  0
 0  0  0         0  0  0
 
 0  0  0         0  0  0

 0  0  0    ->   0  0  0
 1  1  1         1  1  1
 

These examples are in cross form, this means that the corners can be anything (river or grassland). This is only 1 cell being changed, you are expected to apply these patterns to all cells.

• 2 NorthWestRiverBend

 1  1  0    ->   1  2  0
    0               0   

For example:

 0  1  0         0  1  0

Maximum supported dimension in width or height is 16000

The format you input and output is called plain PGM. PGM is portable grey map format so you can use some image programs to view it.

Invalid input (including unexpected EOF) should be aborted immediately with the message:

Invalid input!

Hints

• Initialize your memory when you malloc it
• Remember to check the bounds of the array.
• You should make/extract a cursor so you can pattern match.
• You should consider writing unit tests for the patterns
• You should consider creating new arrays dynamically where need be.
• Return appropriate values from the functions to avoid segmentation faults.
• If you find any task repetitive, make it a function.
• You should read from 1 2D array and write to another.
• You can visualize your output better if you pipe your program through utfdraw.sh (you need GNU sed)

a. Determine the direct materials price variance, direct materials quantity variance, and total direct materials cost variance. Enter a favorable variance as a negative number using a minus sign and an unfavorable variance as a positive number.

b. Determine the direct labor rate variance, direct labor time variance, and total direct labor cost variance. Enter a favorable variance as a negative number using a minus sign and an unfavorable variance as a positive number.

c. Determine variable factory overhead controllable variance, the fixed factory overhead volume variance, and total factory overhead cost variance. Enter a favorable variance as a negative number using a minus sign and an unfavorable variance as a positive number.

take the role of mentor to a new project manager within your organization. This assignment focuses on guidance the mentor provides the new project manager regarding cost.

Cost serves several purposes for an organization: (1) planning and budgeting, (2) assisting in decision making, (3) comparing actual to budget (control), and (4) calculating income generated from operations and projects (score-keeping). Select one these areas and prepare a short document outlining the following items:

• Identify one of the cost purposes listed above.
• Select two of the five cost classifications described in the text: financial statement presentation (cost function): cost behavior, assigning costs to products and services, costs for decision making, and cost of quality (see page 75).
• Describe how knowledge of cost, as described within its classification, is needed to effectively manage costs and improve the success of a project for the stated purpose.
