Express the following Boolean expressions in simpler form; that is, use fewer operators. x is an in (d) !(x <= y)Show the value of x after each of the statements is performed: x = fabs(-6.4);C++ 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.

TEST CASES: If the user inputs a character: Computing for the equivalent resistance A. Series CombinationB. Parallel Combination Enter Choice: B Enter R1: 1 Enter R2: 2 Enter R3: A The value of R3 is not a number. If the user selects “Series Combination” and inputs numbers: Computing for the equivalent resistance A. Series Combination B. Parallel Combination Enter Choice: A Enter R1: 1 Enter R2: 2 Enter R3: 3 The total resistance in series is 6 Ohms.Problem Statement: A 4th grader is having trouble with Permutation and Combination problem in Mathematics, so a friend offered help to create a program they can use. The program contains 3 options, 1st option is for Permutation, 2nd option is Combination and 3rd is for terminating the system. For option 1, Permutation, they uses the following formula: nPr = ; where r must not be greater than n. It should not proceed if this condition is not met. For 2nd option, Combination, they uses the formula : nCr = ; where r must not be greater than n as well. For the 3rd option, the program owner’s information shall be displayed, like name, subject code and account number, before the program terminates. Requirements: Develop the required system and use cpp for the file name Remember that both n and r are variables, their values shall only be entered at run time. The program requires the use of any looping The program requires the use of any conditional Introduce at least 2…
