1 Write a program that returns the count of the occurences of 8 as a digit within an integer.The input to the program should be an integer, not a string.For example 848 yields 2 .You are expected to solve this using a recursive function (no loops)
Hint:Note that mod (%) by 10 yields the rightmost digit (787 % 10 is 7 ) while division by 10 removes the rightmost digit (787/10 is 78)

Imperial Jewelers is considering a special order for 19 handcrafted gold bracelets to be given as gifts to members of a wedding party. The normal selling price of a gold bracelet is $407.00 and its unit product cost is $269.00 as shown below:

Most of the manufacturing overhead is fixed and unaffected by variations in how much jewelry is produced in any given period. However, $8 of the overhead is variable with respect to the number of bracelets produced. The customer who is interested in the special bracelet order would like special filigree applied to the bracelets. This filigree would require additional materials costing $7 per bracelet and would also require acquisition of a special tool costing $453 that would have no other use once the special order is completed. This order would have no effect on the company’s regular sales and the order could be fulfilled using the company’s existing capacity without affecting any other order.

Required:

What effect would accepting this order have on the company’s net operating income if a special price of $362.00 per bracelet is offered for this order? (Enter all amounts as positive values.)

Per Unit Total 19 Bracelets

Incremental costs:

Variable costs:

A curve of radius 73 m is banked for a design speed of 75 km/h . If the coefficient of static friction is 0.39 (wet pavement), at what range of speeds can a car safely make the curve?  [Hint: Consider the direction of the friction force when the car goes too slow or too fast.] Express your answers using two significant figures separated by a comma. (v min, v max in km/h)

1) a. consider a ball of m= 0.50kg. does it take the same amount of additional energy to vertically lift it from 25cm to 30cm as it does to lift from 30cm to 35 cm? if not, which takes more. Why?

b. does it take the same amount of additional energy to speed your car (mass m=1000 kg) up from 25m/s to 30m/s as it does to speed it up from 30m/s to 35m/s? if not which takes more? Why?

c. consider a spring with k=10N/m. Does it take the same amount of additional energy to stretch the spring from 25cm to 30 cm as it does to stretch it from 30cm to 35 cm? If not, Which takes more? why?

Please explain each part thanks!.

For this assignment you will write a C++ program to read a list of words and sort them in alphabetical order.

Requirements:

• You must use a bubble sort OR selection sort algorithm - your choice. You do NOT need to do both.
• You must print the sorted list of words to the console standard out (cout).
• You must use a vector object to store the list of words and you must sort the list "in-place" (meaning, do not create a new list.)
• When reading the data, your program must ignore blank lines and any line that begins with the # symbol.

NOTES:

• Part of the grade will be based on comments according to the style guide.
• You can implement a class if you want to. Writing a class is not required for this assignment.
• Don't make any assumptions about the input data. I may grade using a completely separate list of words. (if so, the format will be the same - no more then one word per line. But assume that blank lines and comments can occur anywhere in the file.)

A company issues a 25-year $6500 bond, redeemable at 95 with bond interest at j1= 6%. The bond is callable at the end of 15 years for $5425 or at the end of 20 years for $6870. Determine the price to guarantee the investor a yield of j1 = 10%.

define with details the income statement and the balance sheet, highlighting the purpose, benefits, and differences between the two.

Shelly's Boutiques and Crafts had revenue of $5,700,000 this year on sales of 575,000 units. Variable costs were 35% and fixed costs totaled $3,150,000. Although the first five years were relatively profitable, increases in competition have led to a negative trend in profitability that has led them to the point where they have to make some changes to stay afloat. The company is evaluating two options to stay afloat.

Option 1:Purchase machinery to automate their operations. This machinery costs $625,000, but will decrease variable costs by 9%.

Option 2:Outsource the production of one of their main components that requires a substantial amount of machinery and skilled labor. This will reduce fixed costs by $425,000, but increases variable costs from their current 35% of sales to 40% of sales.

d.) Calculate the break even point in units after applying Option 1: What is the new fixed cost in total? What is the new contribution margin per unit? What is the new break even point in units?
