Suppose two line segments intersect. The two endpoints for the first line segment are (x1, y1) and (x2, y2) and for the second line segment are (x3, y3) and (x4, y4). Write a program that prompts the user to enter these four endpoints and displays the intersecting point. As discussed in Programming Exercise 3.250, the intersecting point can be found by solving a linear equation. Use the LinearEquation class in Programming Exercise 9.11 to solve this equation.
You can approximate e using the following summation: Write a program that displays the e value for i = 10000, 20000, …, and 100000.
A-Write a program to compute the drag force F, (in Newton) When a body swims through fluid, the drag force is given by 1 F₁ =pV²ACD Take: p= 1000 kg/m3 is the density of fluid, V 1.25 (m/s) is the swimming speed, A=0.25 m² is the frontal area of the body, Cp=0.09 is the coefficient of drag. Matlap
discrete math programing python or c++ the range of values is from 0 to 5 Let Q(x, y) denote “x + y = 5” The domain of x and y is from range 0 to 5 . Implement the code that outputs the truth values of the following quantifications: 1. ∀x ∀y Q(x, y) 2. ∀x ∃y Q(x, y) **Display values of variables x and y if the quantification is true.
Please use C Program In order to discourage excess electric consumption, an electrical company charges its customers a lower rate of P75 for the first 250 kilowatt-hours and a higher rate of P8.5 for each additional kilowatt-hour. In addition, a 10% surtax is added to the final bill. Write a program that calculates the electrical bill given the number of kilowatt-hours consumed as input. At the end, print the number of kilowatt-hours consumed and the computed bill.
Task 9 Write Python code of a program that reads an integer, and prints the integer if it is a multiple of NEITHER 2 NOR 5. For example, 1, 3, 7, 9, 11, 13, 17, 19, 21, 23, 27, 29, 31, 33, 37, 39 ... hint(1): use the modulus (%) operator for checking the divisibility hint(2): You can consider the number to be an integer !%3%===== Example01: Input: 3 Output: 3
8. Write program to check whether a number is Armstrong or not. [Hint] :A positive integer is called an Armstrong number if the sum of cubes of individual digit is equal to that number itself. For examples: 1. 153 = 1*1*1 + 5*5*5 + 3*3*3 // 153 is an Armstrong number. 2. 12 is not equal to 1*1*1+2*2*2 // 12 is not an Armstrong number.
An integer n is divisible by 9 if the sum of its digits is divisible by 9. Develop a program to display each digit, starting with the rightmost digit. Your program should also determine whether or not the number is divisible by 9.
3. Write a Program to find all Roots of a Quadratic Equation
You are conducting a linguistic study and are interested in finding words that contain the letter 't' or 'T' in the first half of the word (including the middle letter if there is one). Specifically, if the first half of the word does contain a 't' or a 'T', your program should output a 1. If the first half does not contain the letter 't' or 'T', but the second half does, then your program should output a 2. Otherwise, if there is no 't' or 'T' in the word at all, your program's output should be -1. You may assume that the word entered does not have more than 50 letters.
4. Write a program to calculate a from the equation a=((5+x)/z)+(y/2.7*w).
Write a program that displays every integer between 1 and 100 that is divisible by 5 or 7, but not both. Write it using While and for.
