Interest Rates Savings accounts state an interest rate and a compounding period. If theamount deposited is P, the stated interest rate is r, and interest is compounded m timesper year, then the balance in the account after one year is P⋅(1+rm)m. For instance, if$1000 is deposited at 3% interest compounded quarterly (that is, 4 times per year), thenthe balance after one year is1000⋅(1+.034)4=1000⋅1.00754=$1,030.34.Interest rates with different compounding periods cannot be compared directly.The concept of APY (annual percentage yield) must be used to make the comparison. TheAPY for a stated interest rate r compounded m times per year is defined byAPY=(1+rm)m−1.(The APY is the simple interest rate that yields the same amount of interest after oneyear as the compounded annual rate of interest.) Write a program to compare interestrates offered by two different banks and determine the most favorable interest rate. SeeFig. 4.24.
Periodic compounding
The total accumulated value, including the principal sum P, is given by the formula:
where:
nt
A = P(1 + 1) "²
n
A is the final amount Accumulated Value
P is the original principal sum
r is the nominal annual interest rate
n is the compounding frequency
t is the overall length of time the interest is applied (expressed using the same time units as r, usually years).
Using the above formula write a program that will display the following table.
Principal-Value | Times-Interest-Compunded | Annual-Int-Rate | Term | Accumulated-Value

Golf scores record the number of strokes used to get the ball in the hole. The expected number of strokes varies from hole to hole and is called par (i.e. 3, 4, or 5). Each score's name is based on the actual strokes taken compared to par:
"Eagle": number of strokes is two less than par
"Birdie": number of strokes is one less than par
"Par": number of strokes equals par
"Bogey": number of strokes is one more than par
Given two integers that represent par and the number of strokes used, write a program that prints the appropriate score name. Print "Error" if par is not 3, 4, or 5.
Ex: If the input is:
4 3
the output is:
Birdie (in java please)

- Introduction Some number of teams are participating in a race. You are not told how many teams are participating but you do know that: Each team has a name, which is one of the uppercase letters A-Z. No two teams have the same name, so there are a maximum number of 26 teams. Each team has the same number of members. No two runners cross the finish line at the same time – i.e. there are no ties. At the end of the race we can write the results as a string of characters indicating the order in which runners crossed the finish line. For example: ZZAZAA We can see there were two teams: A and Z. Team A’s runners finished in 3rd, 5th and 6th place. Team Z’s runners finished in 1st, 2nd and 4th place. Scoring the race Each runner is assigned a score equal to their finishing place. In the example above team Z’s runners achieved scores of 1, 2 and 4. Team A’s runners scores were 3, 5, and 6 respectively. The team’s score is the sum of the members score divided by the number of people on…arrow_forwardGolf scores record the number of strokes used to get the ball in the hole.

While spacecraft A doubles its speed every day, spacecraft B triples its speed in the same period. Given their initial speeds, your task is to determine how many days spacecraft B will take to travel faster than spacecraft A. If the initial speed of spacecraft A is 7, it will be 14 after 1 day, 28 after 2 days, and so on. If the initial speed of spacecraft B is 4, it will be 12 after 1 day, 36 after 2 days, and so on. If the initial speed of spacecrafts A and B are 7 and 4, respectively, B will be faster than A after 2 days, as the speed of A will be 28 and the speed of B will be 36.

- METHODOLOGY A bookstore owner wants you to write a program that calculates the gross pay of an employee. The input to the program is the number of hours the employee works in one week and the employee’s hourly pay rate. The program is to calculate the employee’s gross pay including the possibility of overtime pay. Regular pay is the number of hours the employee worked (up to 40 hours) times the hourly rate. The program is to compute an overtime pay if the employee worked more than 40 hours. All hours beyond 40 should be multiplied to 1.5 for the OT differential pay The program should output the worker’s regular pay, overtime time, and the gross pay (sum of the regular pay and overtime pay).

With each stock number, there is associated a style number in the range of 0 to 50, the number of pairs in each size (sizes range from 3 to 14) and a price. A program is to be written to keep track of the inventory. The user is given the following choices: enter a new record, display a record, change the price of the stock item, or change the number on hand. When specifying a record the user may give either the stock number, or the style number. The array index can be used as a stock number. If the user decides to change the stock on hand, the program should ask which sizes will have their stock on hand changed. The program should be designed to run indefinitely, keeping track of changed in stock.arrow_forwarduse visual basic Depreciation to a Salvage Value of 0 .
