- Interest on a credit card’s unpaid balance is calculated using the average daily balance. Suppose that netBalance is the balance shown in the bill, payment is the payment made, d1 is the number of days in the billing cycle, and d2 is the number of days payment is made before billing cycle. Then, the average daily balance is: averageDailyBalance = (netBalance * d1 – payment * d2) / d1 If the interest rate per month is, say, 0.0152, then the interest on the unpaid balance is: interest = averageDailyBalance * 0.0152 Instructions Write a program that accepts as input netBalance, d1, payment, d2, and interest rate per month (interestRate). The program outputs the interest. Format your output to two decimal places. Input: 100 30 50 7 9.7 Output: 856.83 Test case 2: Input: 255.76 31 55 3 12.3 output: 3080.38Question text Determine whether the ff hypotheses about a computer program • There is an undeclared variable or there is a syntax error in the first five lines. • If there is a syntax error in the first five lines, then there is a missing semicolon or a variable name is misspelled. • There is not a missing semicolon. • There is not a misspelled variable name. lead to the conclusion • There is an undeclared variable. Let the following symbols represent the corresponding statements: uv - There is an undeclared variable. se - There is a syntax error in the first five lines. ms - There is a missing semicolon. vm - There is a misspelled variable name. Thus, in symbolic form, we have to show whether the argument below is valid: uv V se se → (ms V vm) ~ ms ~ VM ... uvGiven a pH value, return whether that value is 'alkaline', 'acidic', or 'neutral'. Return 'invalid'if the value given is less than 0 or greater than 14. Example: pHname(9) → alkaline WRITE IN PYTHON PLEASE

Write TRUE if the statement is true, otherwise, writeFALSE.If P and Q are true statements and R is a false statement, then the statement (P ∧ Q) ∨ R ⇒ (¬Q) is true.Interest on a credit card’s unpaid balance is calculated using the average daily balance. Suppose that netBalanceis the balance shown in the bill, paymentis the payment made, d1is the number of days in the billing cycle, and d2is the number of days payment is made before the billing cycle. Then the average daily balance is: averageDailyBalance = (netBalance * d1 –payment * d2) / d1 if the interest rate per month is say, 0.0152, then the interest on the unpaid balanceis: interest = averageDailyBalance * 0.0152 Design a program that accepts as input netBalance, payment, d1, d2, and interest rate per month. The program outputs the interest charged. Format your output to two decimal places. C++
- Serendipity Booksellers has a book club that awards points to its customers based on the number of books purchased each month. The points are awareded as follows: If a customer purchases 0 books, he or she earns 0 points. If a customer purchases 1 book, he or she earns 5 points. If a customer purchases 2 books, he or she earns 15 points. If a customer purchases 3 books, he or she earns 30 points. If a customer purchases 4 or more books, he or she earns 60 points. Creat an application in C# that lets the user enter the number of books that he or she has purchased this month and displays the number of points awarded.Suppose p: 'You get a speeding ticket' and q: 'Your insurance rate goes up.' Select the correct symbolization for the statement 'If your insurance rate doesn't go up then you don't get a speeding ticket'. Choices:a)~p→~q b)cannot be determined c)~q→~p d)~q∧~pWhen you borrow money to buy a house, a car, or for some other purpose, you repay the loan by making periodic payments over a certain period of time. Of course, the lending company will charge interest on the loan. Every periodic payment consists of the interest on the loan and the payment toward the principal amount. To be specific, suppose that you borrow $1,000 at an interest rate of 7.2% per year and the payments are monthly. Suppose that your monthly payment is $25. Now, the interest is 7.2% per year and the payments are monthly, so the interest rate per month is 7.2/12 = 0.6%. The first months interest on $1,000 is 1000 0.006 = 6. Because the payment is $25 and the interest for the first month is $6, the payment toward the principal amount is 25 6 = 19. This means after making the first payment, the loan amount is 1,000 19 = 981. For the second payment, the interest is calculated on $981. So the interest for the second month is 981 0.006 = 5.886, that is, approximately $5.89. This implies that the payment toward the principal is 25 5.89 = 19.11 and the remaining balance after the second payment is 981 19.11 = 961.89. This process is repeated until the loan is paid. Write a program that accepts as input the loan amount, the interest rate per year, and the monthly payment. (Enter the interest rate as a percentage. For example, if the interest rate is 7.2% per year, then enter 7.2.) The program then outputs the number of months it would take to repay the loan. (Note that if the monthly payment is less than the first months interest, then after each payment, the loan amount will increase. In this case, the program must warn the borrower that the monthly payment is too low, and with this monthly payment, the loan amount could not be repaid.)
- Write this statement in words: ? = {? ∈ ? +| − 1 ≤ ? ≤ 1}The interest paid on a savings account is compounded daily. This means that if you start with startbal dollars in the bank, at the end of the first day you’ll have a balance ofstartbal * (1 + rate/365)dollars, where rate is the annual interest rate (0.10 if the annual rate is 10 percent). At the end of the second day, you’ll havestartbal * (1 + rate/365) * (1 + rate/365)dollars, and at the end of n days you’ll havestartbal * (1 + rate/365)ndollars. Write a program that processes a set of data records, each of which contains values for rate, startbal, and n and computes the final account balance.Explain the multiple meanings of the operators << and >>.
