Is the net work done on an object at rest or moving at a constant velocity?

2 answers:

“If an object is moving with a constant velocity, then by definition it has zero acceleration. So there is no net force acting on the object. The total work done on the object is thus 0 (that's not to say that there isn't work done by individual forces on the object, but the sum is 0 ).”

a bond has a face value of $1,000, an annual coupon rate of 7 percent, yield to maturity of 10 percent, and 20 years to maturity

rewona [7]

The bond that has a face value of $1,000 has a duration of 10 years.

A bond is a type of security in the financial world where the issuer (debtor) owes the holder (creditor) a debt and is required, depending on the terms, to repay the bond's principal (i.e., the amount borrowed) at the bond's maturity date as well as interest (referred to as the coupon) over a predetermined period of time. The interest is typically due at regular intervals, such as every six months, once a year, and less frequently at other times. To finance long-term investments or, in the case of government bonds, to finance immediate expenses, the borrower can obtain external funds through the sale of bonds. Both bonds and stocks are considered to be forms of security, but the main distinction between the two is that (capital) stockholders have an equity stake in a company, whereas bondholders have a creditor stake.

Bubba's Custom Shrimp Catering uses activity-based costing to determine the cost of its catering events. The firm has two activi

Svetach [21]

Answer:

The best option would be option d since it provides the least cost and therefor a higher possibility of being the most profitable.

a. Total cost for option a=$37,000

b. Total cost for option b=$36,250

c. Total cost for option c=$33,750

d. Total cost for option d=$30,625

Explanation:

Step 1: Determine the formula total cost

Total cost=direct costs+cooking cost+serving cost+improvement costs

Consider option a

where;

direct costs=$400×25=$10,000

cooking costs=cooking cost per catering event×number of catering events

cooking costs per year=500×25=$12,500

serving cost=serving cost per plate×number of events×number of plates per event

serving cost per plate=$12

number of events=25

number of plates per event=(80/100)×50=40

serving cost=12×25×40=$12,000

Improvement costs=$2,500

replacing;

Total cost=10,000+12,500+12,000+2,500=$37,000

Consider option b

where;

direct costs=$10,000

cooking costs=cooking cost per catering event×number of catering events

cooking costs per year=500×25=$12,500

serving cost=serving cost per plate×number of events×number of plates per event

serving cost per plate=$12×0.75=$9

number of events=25

number of plates per event=50

serving cost=9×25×50=$11,250

Improvement costs=$2,500

replacing;

Total cost=10,000+12,500+11,250+2,500=$36,250

Consider option c

where;

direct costs=$10,000×0.75=$7,500

cooking costs=cooking cost per catering event×number of catering events

cooking costs per year=500×25=$12,500

serving cost=serving cost per plate×number of events×number of plates per event

serving cost per plate=$12×0.75=$9

number of events=25

number of plates per event=50

serving cost=9×25×50=$11,250

Improvement costs=$2,500

replacing;

Total cost=7,500+12,500+11,250+2,500=$33,750

Consider option d

where;

direct costs=$10,000×0.75=$7,500

cooking costs=cooking cost per catering event×number of catering events

cooking costs per year=500×25×0.75=$9,375

serving cost=serving cost per plate×number of events×number of plates per event

serving cost per plate=$12×0.75=$9

number of events=25

number of plates per event=50

serving cost=9×25×50=$11,250

Improvement costs=$2,500

replacing;

Total cost=7,500+9,375+11,250+2,500=$30,625

Use the following statement to answer parts a) and b). Five hundred raffle tickets are sold for $3 each. One prize of $200 i

vazorg [7]

Answer:

A.) - 2.6

B.) 0.4

Explanation:

Ticket price = $3

Winning price = $200

Probability of winning(Pwin) = (1/500)

Probability of not winning (Ploss) = [ 1 - (1/500)] = 499/500

Net income if Raul wins (Nwin) = $200 - $3 = $197(no refund)

Net loss if Raul does not win(Nloss) = - $3

A.) Expected value is calculated by;

(Pwin × Nwin) + (Ploss × Nloss)

((1/500) × 197) + ((499/500) × - 3)

0.394 - 2.994 = - 2.6

B.) Fair Value is calculated by;

Cost of ticket + Expected value

3 - 2.6 = 0.4
