Implement the quadratic_formula() function. The function takes 3 arguments, a, b, and c, and computes the two results of the quadratic formula: x1=−b+b2−4ac2a x2=−b−b2−4ac2a The quadratic_formula() function returns the tuple (x1, x2). Ex: When a = 1, b = -5, and c = 6, quadratic_formula() returns (3, 2). Code provided in main.py reads a single input line containing values for a, b, and c, separated by spaces. Each input is converted to a float and passed to the quadratic_formula() function. Ex: If the input is: 2 -3 -77 the output is: Solutions to 2x^2 + -3x + -77 = 0 x1 = 7 x2 = -5.50 code: # TODO: Import math module def quadratic_formula(a, b, c):# TODO: Compute the quadratic formula results in variables x1 and x2return (x1, x2) def print_number(number, prefix_str):if float(int(number)) == number:print("{}{:.0f}".format(prefix_str, number))else:print("{}{:.2f}".format(prefix_str, number)) if __name__ == "__main__":input_line = input()split_line = input_line.split(" ")a =…
C++ Programming Language: Enhance the code given by outputting: The largest number of the sequence a0 ,a1 ,a2 , ..., ak. The position of the largest number Test your program for the following values of x: 75, 111, 678, 732, 873, 2048, and 65535. Example: "For example, for the input sequence: 75, 226, 113, 340, 170, 85, 256, 128, 64, 32, 16, 8, 4, 2, 1, the program output should contain the following: The largest number of the sequence is 340 The position of the largest number is 4" Code Given: #include <iostream> #include <iomanip> using namespace std; int main() { long x; int count; long a_n; cout << "Enter a nonnegative integer: "; cin >> x; cout << endl; count = 0; a_n = x; cout << a_n << ", "; while (a_n !=1) { if (a_n %2==0) a_n = a_n / 2; else a_n = 3 * a_n + 1; count++; cout << a_n <<", "; } cout << endl; cout << "The integer k such that a_k = 1 is " << count << endl; return0; }
Write a C++ program called Fibonacci to display the first 20 Fibonacci numbers F(n),where F(n)=F(n–1)+F(n–2) and F(1)=F(2)=1. Also compute their average. The output shall looklike:The first 20 Fibonacci numbers are:1 1 2 3 5 8 13 21 34 55 89 144 233 377 610 987 1597 2584 4181 6765The average is 885.5
Knowing that (x + 1)2 = x2 + 2x + 1,and that multiplication is more time consuming than addition, write an efficientprogram that displays the first ten natural numbers and their squares. Knowingthat (x + 1)3 = x3 + 3x2 + 3x + 1, the same process can be followed to displaythe cubes of these numbers.Here is a sample run: 0^2 = 01^2 = 12^2 = 4...8^2 = 649^2 = 8110^2 = 100
Write a program to determine the possible location(s) of a missing symbol of enclosure given a mathematical representation of a string. Although spaces are used between characters for readability, the input string will have no spaces. All operands will be integers less than 1000, and the order of evaluation for the symbols is parentheses, brackets and then braces. For example: {[(2 + 3) * 6 / 10} - One bracket is missing. It could be correctly placed in several locations: {[(2 + 3)] * 6 / 10} -Location 8 {[(2 + 3) * 6] / 10} -Location 10 {[(2 + 3) * 6 / 10]} -Location 13 Input from the keyboard a string of characters with no spaces representing a mathematical expression. The first position of the string will start at number 1. Each type of symbol of enclosure will be used at most once, and each expression will have at least one missing symbol of enclosure. The operators used will be: +, −, * and /. Single integers will never be enclosed. For each line of input list output to the screen…
Write a code in C++: Write a program to factor a polynomial of the form x² + bx + c, where b and c are integers AND also modify the program so that it can also factor polynomials of the form ax2 + bx + c , where a, b, and c are integers. For example, the polynomial "- 2x² - 3x + 2" can be factored as: "- 2x² - 3x + 2 = (-2x + 1)(x + 2) = - (2x - 1)(x + 2)". The output at the end should be this exact quote: "- 2x² - 3x + 2 = (-2x + 1)(x + 2) = - (2x - 1)(x + 2)"
Write a C++ program: to iteratively compute Fibonacci numbers (named after an Italian mathematician). Some Fibonacci numbers are 1,1,2,3,5,8,... where the next number is found by summing the preceding two numbers. Your program is not assured of recieving good data, thus if -2 is recieved as the number of numbers, then an error should be reported. Try n = 5, 7, 10, -3

In each of the following code snippets, data is copied from x to y. How many bytes of data arecopied? The answer should be a C expression.Example: int x[10], y[10];...for (int i=0; i<10; i++)x[i] = y[i];Answer: 10*sizeof(int)Example: int *x, *y; ...; y = x;Answer: sizeof(int*) (e) int x=10, y=x;(f) int x[10]; int *y = x;(g) int x[10] = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9};void f(int y[5]) { ... }int main() { f(x); }(h) int x[10], y[10];...memcpy(y, x, 5*sizeof(int));
A robot is placed at the origin of a 2D coordinate plane (i.e. position (0, 0)). The robot is given a string Scontaining N characters in {N, E, S, W} as its instructions. For each character from the beginning of the string,the robot has to move 1 unit to the following direction:• If the character is N, the robot has to move 1 unit to the positive y-axis direction.• If the character is E, the robot has to move 1 unit to the positive x-axis direction.• If the character is S, the robot has to move 1 unit to the negative y-axis direction.• If the character is W, the robot has to move 1 unit to the negative x-axis direction.You do not know the string S. However, you know another string P that is an anagram of S (i.e. P has thesame number of N, E, S, W characters as S). You also have M data points: T1...M, X1...M, and Y1...M. For alli, you know that the robot is at position (Xi, Yi) after moving exactly Ti units.You want to know the number of possible string S that satisfies all the…
Write a program in Python that asks the user to input an integer and print two integers, root and power, such that 1 < power < 6 and root ** power is equal to the integer entered by the user. If no such pair of integers exists, it should print a message to that effect.
On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of f0 * rn, where n is the distance (number of keys) from that key, and r is 2(1/12). Given an initial key frequency, output that frequency and the next 4 higher key frequencies. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print('%0.2f %0.2f %0.2f %0.2f %0.2f' % (your_value1, your_value2, your_value3, your_value4, your_value5))
