Chapter 3, Problem 2PP
(This Project requires that you know some basic facts about complex numbers, so it is only appropriate if you have studied complex numbers in some mathematics class.)
Write a C++
| ax2 + bx + c = 0 |
(where a is not zero) are given by the formula
| (−b ± sqrt(b2 − 4ac)) / 2a |
The value of the discriminant (b2 − 4ac) determines the nature of roots. If the value of the discriminant is zero, then the equation has a single real root. If the value of the discriminant is positive then the equation has two real roots. If the value of the discriminant is negative, then the equation has two complex roots.
The program takes values of a, b, and c as input and outputs the roots. Be creative in how you output complex roots. Include a loop that allows the user to repeat this calculation for new input values until the user says she or he wants to end the program.

CODE USING C++
We've already tried comparing 3 numbers to see the largest among all, so let's try a more complicated mission where we locate where among the 5-digit integer is the largest one. There are only 4 possible cases for this mission:
if the largest digit is the first digit, print "Leftmost"
if the largest digit is the third digit, print "Middle"
if the largest digit is the last digit, print "Rightmost"
if none of the above is correct, print "Unknown"
Now, show me how far you've understood your lessons!
Input
A line containing a five-digit integer.
14632
Output
A line containing a string.
Middle

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_forward
- PYTHON PROGRAMMING (practice review for final) (please see attached)arrow_forwardIn Python A soup company is interested in finding out how much of their soup will go into various sized cans. The user will input the diameter of the can end, and the height of the can. The volume of a cylinder is the well known formula: volume = area of the ends * height of cylinder. The twist is that a can of soup can not be completely filled to the top; only 95% of the volume can be filled with soup; the remaining 5% must remain empty to allow for expansion. NOTE: when computing the area, use pi to at least 5 significant digits (eg, 3.14159) or use the constant math.pi. You should define a function named soup_volume which takes two parameters, the diameter of the can in cm, and the height of the can in cm, in that order. The function should return a float value, which is the volume of soup that the can is able to hold. The function should not round the value, but when printing the value in the main program, format it to show only 2 decimal places.

- [Python Language] A common back-of-the-envelope technique for estimating a runner’s marathon time is to take their best half-marathon time, multiply by two and add ten minutes. This works pretty well unless the marathon course is hilly.If it is hilly, we add an extra 20 minutes to the estimate. Write a program that takes two lines of input: a float giving the half- marathon time in minutes and an integer indicating whether the marathon course is hilly(1) or not (0). It prints a float giving the estimated number of minutes the runner will take to run the full marathon. Write your pro- gram in a file named marathon.py.arrow_forwardCode the follow.arrow_forwardplease do it in python language first picture is problem and second one is just hint for you. thanksarrow_forward

Note that the result won't be exact due to computer limitations of storing all decimal values. Use the round() function (e.g. round(12.4) results in 12 and round(12.5) results in 13) Note 1 Import math package inside the function and use math.sqrt() function. Note 2 There is no need to ask for input or print the output. Just submit the function with the following format: Соpy def fib(int1): # Your code here where int1) is a nonnegative integer.
