- The expression intNum * intNum * intNum is equivalent to which of the following expressions? intNum ^ 3 intNum * 3 intNum ^ 2 * intNum Both a and c.arrow_forwardFy F= 40N 75 mm Fx 325 mm Figure 1 F = (4/5)F and F, = /5)F Total Moment at B = F,dy + (-F,)d, Where d, and dy, are the perpendicular distance in meter. In this example it is given that d, = 175mm and dy = 325 mm. As a programmer it is your responsibility to write a code to solve for the total moment at B. The requirement to find the total moment is as follows: 1) Please write a code using object-oriented programming to solve for the total moment. (You can test your code using the data given above.) 2) Declare a class, Moment. 3) The user needs to enter the information for the d, and d,. Write a statement to ask the user on the number of data that the user want to calculate the moment with different n values of d, and dy. 4) Declare a constructor to initialize the input, decide which one of the inputs that you want to use constructor for the initialization. 5) Print the output to the screen and a datafile name TotalMoment.txtarrow_forwardTranslate the statement into equation: When three is multiplied by one less than a number x, the result is 10 less than 5 times the number x.arrow_forward
- Q6: The volume of oil stored in an underground 200-foot deep eylindrical tank is determined by measuring the distance from the top of the tank to the surface of the oil. Knowing this distance and the radius of the tank, the volume of oil in the tank can be determined by using this formula: volume = 7 radius (200- distance) Using this information, write a program that uses a function called volume to calculate the volume of oil in the tank.arrow_forwardCalculating Truth Value of Formulas If A, B, and C are true statements and X, Y, and Z are false statements, calculate the truth value of the following formulas. ~(((~A & B) & (~X & Z)) & ~((A & ~B) v ~(~Y & ~Z))) X is False; H, G are unknown. Can you calculate the value of the following formulas? Yes, or No. Show and explain. (G -> (H -> G)) -> X Yes, or No. Show and explain.arrow_forward31. If originally x=4, what is the value of x after the evaluation of the expression: x++arrow_forward

Assume the following: int a = 3, b = 7; float x = 6.0, y = 3.1 z = 2.0 (int)y * 10 + barrow_forwardAfter the following statements, what are the values of x and y? * x = 15 y = x x = 22 x is 15 and y is 15 x is 22 and y is 22 O x is 15 and y is 22 x is 22 and y is 15arrow_forward7128 LAB: Variables/Assignments: Using math functions Given three flgating-point numbers xy and z outputx to the power of y x to the power off (v to the power of z the absolute value of x, and the squareroot of *y to the power of z) Output all results with five digits atter the decimal point, which can be achieved as followS Put result to output with 5 decinal places Ex If the input is 5.0 2.5 1.5 the output is 55.90170 579.32402 5.00000 6.64787 Hint Coral has built-in math functions (disoussed elsewnere) that may be used 128 1 LAB Variables/Assignments Using math functions LAB 0/10 ACTIVITY Load default template...arrow_forward
- If you divide an integer by 11 what are the possible values of the remainder?arrow_forwardSuppose you want to deposit a certain amount of money into a savings account, and thenleave it alone to draw interest for the next 10 years. At the end of 10 years, you would like tohave $10,000 in the account. How much do you need to deposit today to make that happen?You can use the following formula, which is known as the present value formula, to find out:The terms in the formula are as follows: [5 marks]• P is the present value, or the amount that you need to deposit today.• F is the future value that you want in the account. (In this case, F is $10,000.)• r is the annual interest rate.• n is the number of years that you plan to let the money sit in the account.Write a method named presentValue that performs this calculation. The method should accept the future value, annual interest rate, and number of years asarguments. It should return the present value, which is the amount that you need to deposit today.Demonstrate the method in a program that lets the user experiment with…arrow_forwardWhich of the following statements is false? * A. The value of the following expression is 3: 17 % 5 B. The value of the following expression is 0.5: 7.5 % 3.5 C. You can use the remainder operator for applications such as determining whether one number is a multiple of another. D. You can use the remainder operator to determine whether a number is odd or even.arrow_forward
