7. Write a function that evaluates the area of a pentagon. Use "math.pi", for pi, and "math.sqrt" for square root. Write the solution on the space provided below. You do not need to run the code. DII 3.2 (Geometry: area of a pentagon) Write a program that prompts the user to enter the length from the center of a pentagon to a vertex and computes the area of the pen- tagon, as shown in the following figure. 3√3 2 The formula for computing the area of a pentagon is Area -s², where s is TT the length of a side. The side can be computed using the formula s = 2r sin 5 = where r is the length from the center of a pentagon to a vertex. Here is a sample run:
6.14 Lab: Reversing an Integer. In this problem, your task is to complete the reverseNumber(num) function. The input of the function is an integer number num. The function should return a number where all the digits are reversed from the original number. You can assume that the input will be a non-negative integer. Example 1: If the input is: 123 The output is: 321 Example 2: If the input is: 321 The output is: 123 Example 3: If the input is: 1000 The output is: 1 Brainstorming. Oftentimes, a problem as formulated can be made easier when you change the way the data is represented. In this case, this problem can be solved in a clever way using strings. If you first convert the number into a string, you can then reverse the string and convert the number back to an integer. def reverseNumberUsingString(num): numInStringFormat = str(num) #converts the number into a string reversedNumberInStringFormat = numInStringFormat[::-1] #reverses the string reversedNumber =…

2.13 LAB: Driving costs Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 20 miles, 75 miles, and 500 miles. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print('{:.2f} {:.2f} {:.2f}'.format(your_value1, your_value2, your_value3)) Ex: If the input is: 20.0 3.1599 Then the output is: 3.16 11.85 79.00 Note: Real per-mile cost would also include maintenance and depreciation. 318650.2047284.qx3zqy7 LAB 2.13.1: LAB: Driving costs 0/10 ACTIVITY main.py Load default template...
***Microsoft Visual Studios (C++)*** Write a program that given two coordinate pairs and a third single coordinate will linearly interpolate or extrapolate the third second coordinate. For example, let's say at 50 degrees Celsius the length of a metal rod is 5.4 cm and at 60 degrees Celsius the length is 5.5cm. I can interpolate the length at 53 degrees Celsius by doing 5.4cm + 3*(.1/10)=5.43cm. Your program does not need to continuously run, but should prompt the user for two coordinate pairs, the third first coordinate and return the extrapolated or interpolated third second coordinate.
Q1) Write a program that • Asks for a natural number (Assume that number is n) • Draws the following triangular shape with n lines of numbers. Example: (n = 5) 1. 2 1 3 21 4 3 2 1 5 4 3 21 (n = 3) 1. 21 3 21 In the triangular shape, There is a space character between each neighboring numbers on the same line. • The rightmost number is supposed to be 1. • The numbers are ordered in a descending order. The ith line should contain i numbers. The numbers are aligned right.
3.6 LAB: Number pattern Write a recursive function called print_num_pattern() to output the following number pattern. Given a positive integer as input (Ex: 12), subtract another positive integer (Ex: 3) continually until 0 or a negative value is reached, and then continually add the second integer until the first integer is again reached. For coding simplicity, output a space after every integer, including the last. Do not end output with a newline. Ex. If the input is: 12 3 the output is: 12 9 6 3 0 3 6 9 12

Let(x1,y1)and(x2,y2)be the geographical latitude and longitude of two points. The great circle distance between the two points can be computed using the following formula: \[ d=\operatorname{radius} \times \arccos \left(\sin \left(x_{1}\right) \times \sin \left(x_{2}\right)+\cos \left(x_{1}\right) \times \cos \left(x_{2}\right) \times \cos \left(y_{1}-y_{2}\right)\right) \] Write a program that prompts the user to enter the latitude and longitode of two points on the earth in degrees and displays its great circle distance. The average radius of the earth is6,371.01 km. Note you need to convert the degrees into radians using the Math, toRadi ans method since the Java trigonometric methods use radians. The latitude and longitude degrees in the formula are for north and west. Use negative to indicate south and…
4.7: Time Machine Your time machine is capable of going forward in time up to 24 hours. The machine is configured to jump ahead in minutes. To enter the proper number of minutes into your machine, you would like a program that can take a start time (in hours, minutes, and a Boolean indicating AM or PM) and a future time (in hours, minutes, and a Boolean indicating AM or PM) and calculate the difference in minutes between the start and future time. A time is specified in your program with three variables: int hours, minutes; bool isAM; for example, to represent 11:50 PM, you would store: hours = 11,minutes = 50,isAM = false This means that you need six variables to store a start and future time. Write a program that allows the user to enter a start time and a future time. Include a function named computeDifference that takes the six variables as parameters that represent the start time and future time. Your function should return, as an int, the time difference in minutes. for example,…
