- True or False? The result of a logical expression cannot be assigned to an int variable.arrow_forward?Which of the following assignment statements is not correct x = ++x; x++ = y + 2; x += ++y; X = x++ + 2;arrow_forward• FormulaEvaluator.java Requirements: Evaluate the following expression for any value of the variable x, and save the result in a variable of the type double. You must use the abs(), pow(), and sqrt() methods of the Math class to perform the calculation. You may use a single assignment statement with a somewhat large expression, or you may break the expression into multiple assignment statements. The latter may be easier to debug if you are not getting the correct result. 5x +3} ( √8x* — 6x²³ + 4x² + |20x+1) (9x³+7x² +5x+3) Next, determine the number of digits to the left and to the right of the decimal point in the result. [Hint: You can convert the double variable into a String variable using the static method Double.toString(result). Then, on this String variable use the indexOf() method from the String class to find the position of the decimal point (".") and use the length() method to find the length. Knowing the location of the decimal point and the length of the String, you…arrow_forward
- -s is optional and means that the mortgage will be a 15 year mortgage instead of the standard 30 year mortgage you would use as a default. -r is required and the argument is the yearly interest rate for the loan. The interest rate should be between 3% and 10% inclusive. -d is optional and the argument is the downpayment that will be made on the loan. It cannot be larger than the price of the home. You will print out the resulting payment amount as follows. Use rounding to keep money to two decimals and percentages to three decimals. "The payment on a loan of $###,###.## with an interest rate of #.###% for a term of ## years will be $##,###.##" There should be no other output at all to the screen.  1. 0.004166667 2. 1.004166667 3. 360 4. 0.2238265956 5. 0.7762 6. 0.00536822 7. 536.82 Add PMI since there is no down payment: 1. 1% * 100000 = 1000 2. 1000 / 12 = 83.33 3. 536.82 + 83.33 = 620.15arrow_forward-s is optional and means that the mortgage will be a 15 year mortgage instead of the standard 30 year mortgage you would use as a default. -r is required and the argument is the yearly interest rate for the loan.

- OBJECT:      To compute the net pay of an employee, given his/her pay rate, number of hours, and tax rate.  INPUT:         his/her name, pay rate, and number of hours. You will prompt the user with a friendly message to enter the employee’s name, pay rate and number of hours. Note that you must use the dash (-) to connect the first name to the last name so that the name can be read using the cin statement. For example, John-Doe  OUTPUT:     the employee’s gross pay, tax deduction, and net pay. For example:  Name:                                     John-Doe Your gross pay is:                 900.00 Your tax deduction is:            90.00 Your net pay is:                     810.00   METHOD:    the gross pay is the pay rate times the number of hours. The tax deduction is computed as follows: If the gross pay is less than 1000.00, it is 10% of the total pay; otherwise, it is 15% of the gross pay. The net pay is the gross pay minus the tax deduction.   TOPICS:…arrow_forwardAssume x is 10, y is 7, and z; x and y are int, z is bool.

- Primitive-type local variables are initialized by default. State whether the statement is true or false. If false, explain why.arrow_forwardIn Python Text-based adventure game: Pretend you are creating a text-based adventure game. At different points in the game, you want the user to select to fight, run, or hide from certain enemies. The selection variable must be sent as an argument into the choice() function. The user should enter 1 to fight, 2 to run, or 3 to hide in the main(). The choice() function should print one of the three options. Add an if statement in the choice() function to make the correct selection.arrow_forwardC++ Programming Exercise: A real estate office handles, say, 50 apartment units. When the rent is, say, $600 per month, all the units are occupied. However, for each, say, $40 increase in rent, one unit becomes vacant. Moreover, each occupied unit requires an average of $27 per month for maintenance. How many units should be rented to maximize the profit? Write a program that prompts the user to enter: a. The total number of of units. b. The rent to occupy all the units. c. The increase in rent that results in a vacant unit. d. Amount to maintain a rented unit. The program then outputs the number of units to be rented to maximize the profit.arrow_forward
