Write a Python program that verifies the formula with the help of the Python Math module. Note that the trigonometric functions in the module act on the angles in radians. Your program should perform the following steps 3 times:_____. 1. Pick a random number between 0 and 180 degrees representing an angle in degrees, say Dangle 2. Convert the angle from degrees to radians, say Rangle 3. Use the Math module to find and print the values of sin(Rangle) and cos(Rangle), and 4. Compute and print the value of the above expression: sin^2(Rangle) + cos^2(Rangle).You can then visually verify if the result printed is 1 (or close to it). Hint: angle_in_radians = (angle_in_degrees * Pi)/180

Your school is hosting a diving contest, and they need a programmer to work on the scoreboard! Your job is to calculate each diver's total after the three judges hold up their individual scores. Write the function calculate_score which takes a tuple of three numbers from 0 to 10 and calculates the sum. A perfect dive is worth 30 points, a belly flop is worth 0. For example: calculate_score((10, 10, 10)) # => 30 calculate_score((9, 9, 6)) # => 24

Write a program Gas.java that computes and displays the price a person will pay for gas at the gas station. The program takes three command-line arguments: two double arguments referring to the price per gallon, and the number of gallons of gas, and one boolean argument referring to whether the person pays cash or credit (true for cash, false for credit). If the person pays with a credit card, there is an extra charge of 10% of the total price. Gas is never free. A person stopping to buy gas will always buy some amount of gas. Print the error message "Illegal input" if any of the double inputs is zero or negative, and end the program.

The Goal: Similar to the first project, this project also uses the random module in Python. The program will first randomly generate a number unknown to the user. The user needs to guess what that number is. (In other words, the user needs to be able to input information.) If the users guess is wrong, the program should return some sort of indication as to how wrong (e.g. The number is too high or too low). If the user guesses correctly, a positive indication should appear. Youll need functions to check if the user input is an actual number, to see the difference between the inputted number and the randomly generated numbers, and to then compare the numbers. Concepts to keep in mind: Random function Variables Integers Input/Output Print While loops If/Else statements

Assume that at time 5 no system resources are being used except for the processor and memory. Now consider the following events:At time 5: P1 executes a command to read from disk unit 3.At time 15: P5s time slice expires.At time 18: P7 executes a command to write to disk unit 3.At time 20: P3 executes a command to read from disk unit 2.At time 24: P5 executes a command to write to disk unit 3.At time 28: P5 is swapped out.At time 33: An interrupt occurs from disk unit 2: P3s read is complete.At time 36: An interrupt occurs from disk unit 3: P1s read is complete.At time 38: P8 terminates.At time 40: An interrupt occurs from disk unit 3: P5s write is complete.At time 44: P5 is swapped back in.At time 48: An interrupt occurs from disk unit 3: P7s write is complete.For time 37, identify which state each process is in. If a process is blocked, further identify the event on which it is blocked.

I need to know how to input this into python on zybooks. I've been stuck on this for days and I keep running into "invalid syntax" or "unknown word red" Summary: Given integer values for red, green, and blue, subtract the gray from each value. Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray). Given values for red, green, and blue, remove the gray part. Ex: If the input is 130 50 130, the output is: 80 0 80 Find the smallest value, and then subtract it from all three values, thus removing the gray.

Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles. Ex: If the input is 20.0 3.1599, the output is: 1.57995 7.89975 63.198 Note: Small expression differences can yield small floating-point output differences due to computer rounding. Ex: (a + b)/3.0 is the same as a/3.0 + b/3.0 but output may differ slightly. Because our system tests programs by comparing output, please obey the following when writing your expression for this problem. First use the dollars/gallon and miles/gallon values to calculate the dollars/mile. Then use the dollars/mile value to determine the cost per 10, 50, and 400 miles. Note: Real per-mile cost would also include maintenance and depreciation.

1. Add an import statement above the class declaration to make the Scanner class available to your program.2. In the main method, create a Scanner object and connect it to the System.in object.3. Prompt the user to enter his/her first name.4. Read the name from the keyboard using the nextLine method, and store it into a variable called firstName (you will need to declare any variables you use).5. Prompt the user to enter his/her last name.6. Read the name from the keyboard and store it in a variable called lastName.7. Concatenate the firstName and lastName with a space between them and store the result in a variable called fullName.8. Print out the fullName.9. Compile, debug, and run, using your name as test data.10. Since we are adding on to the same program, each time we run the program we will get the output from the previous tasks before the output of the current task.

The algorithm S(A, n, i) selects all the j-th smallest elements (with j i) from an array A of n elements, by using linearselect to select each of the j-th smallest elements (with j i). Clearly, one could also implement S alternatively as T(A, n, i), which first sort A (on average-case and on worstcase, the sorting takes time O(n log n) using mergesort) and then select the first i elements. Please compare the average-case complexities of the two algorithms; i.e., For the average-case complexities, under what conditions (on the choices for i), S is better than T or vice versa
