Let (x1, y1) and (x2, y2) be the geographicallatitude and longitude of two points. The great circle distance between the twopoints can be computed using the following formula:d = radius X arccos(sin (x1) X sin(x2) + cos(x1) X cos(x2) X cos(y1 - y2))Write a program that prompts the user to enter the latitude and longitude of twopoints on the earth in degrees and displays its great circle distance.

- The two roots of a quadratic equationax2 + bx + c = 0 can be obtained using the following formula:b2 - 4ac is called the discriminant of the quadratic equation. If it is positive, theequation has two real roots. If it is zero, the equation has one root. If it is negative,the equation has no real roots.Write a program that prompts the user to enter values for a, b, and c and displaysthe result based on the discriminant. If the discriminant is positive, display tworoots. If the discriminant is 0, display one root. Otherwise, display “The equationhas no real roots.”Note you can use Math.pow(x, 0.5) to compute √x.

Odd numbers (like the 5 or 95) go north/south, and evens (like the 10 or 90) go east/west. Auxiliary highways are numbered 100-999, and service the primary highway indicated by the rightmost two digits. Thus, the 405 services the 5, and the 290 services the 90. Your program will prompt the user to type a highway number ("Please enter a highway number, Ex: 65: "), read in the number typed by the user, and print out whether it is a primary or auxiliary highway. If auxiliary, indicate what primary highway it serves. Also your program must indicate if the (primary) highway runs north/south or east/west, that it is an invalid number if not between 0 and 999. Ex: If the input is: 90 the output is: The 90 is primary, going east/west. Ex: If the input is: 290 the output is: The 290 is auxiliary, serving the 90, going east/west. Ex: If the input is: 0 the output is: 0 is not a valid interstate highway number. #include <iostream>using…arrow_forwardA complex number is a number in the form a+bi, where a and b are real numbers and i is √(-1) The numbers a and b are known as the real part and imaginary part of the complex number, respectively. You can perform addition, subtraction, multiplication, and division for complex numbers using the following formulas: a + bi + c + di = (a+c) + (b+d)i (addition) a + bi − (c + di) = (a−c) + (b−d)i (subtraction) (a + bi) * (c + di) = (ac−bd) + (bc+ad)i (multiplication) (a + bi) / (c + di) = (ac+bd) / (c2+d2) + (bc−ad)i / (c2+d2) (division) You can obtain the Absolute Value for a complex number using the following formula: |a + bi| = √(a2 + b2) A Complex number can be interpreted as a point on a plane by identifying the (a,b) values as the coordinates of the point. The absolute value of the complex number corresponds to the distance of the point to the origin, as shown in the example below.
