In geometry, an octagon is an eight-sided polygon. Each internal angle is 135 degrees. Based on what you have learned in this course and using the appropriate commands, you are asked to implement a python program that draws the below diagram using the turtle. You should consider the following points in your solution: 1. Each octagon side has a length of 40 units. 2. Each octagon has a different color. 3. The border lines should be thick enough. 4. The final shape of the output should be as shown above. 5. You might place the desired colors in a list to access them by index in the drawing loop. 6. Make sure to set properly the starting position (x & y) of your drawing, to maintain the above diagram. - Tip: You can use the below colors and fills colors=['red', 'blue', 'brown', 'green', 'orange', 'purple', 'cyan', 'yellow'] fill= ['yellow', 'grey', 'orange', 'pink', 'black', 'cyan', 'purple', 'red']

write a program in python language: You are given a rectangular board of Mx N squares. Also you are given an unlimited number of standard domino pieces of 2 x1 squares. You are allowed to rotate the pieces. You are asked to place as many dominoes as possible on the board so as to meet the following conditions: 1. Each domino completely covers two squares. 2. No two dominoes overlap. 3. Each domino lies entirely inside the board. It is allowed to touch the edges of the board. Find the maximum number of dominoes, which can be placed under these restrictions. ex: 24 4
You are working as a software developer on NASA's Mars Explorer robotic rover project. You need to implement some code to compute the surface area of the 3D, tube-shaped part shown below: a cylinder of radius r and height h (in units centimeters) with a hollowed-out center also in the shape of a cylinder with radius n and height h (also in cm). Both the outside and the inside of the tube will need to be coated in a thin layer of gold, which is why we need to know its surface area. Write code that will compute and print the total surface area of the shape. n esc r Examples: Inputs r = 10, n = 8.5, h = 22.5 r = 9.25, n = 6.8, h r = 4.15, n = 3.9, h = 11.7 = 12.16 X h Output Value 2789.7342763877364 1473.347264273195 604.4267185874082 2 3 80 F3 000 DO F4 ✓0 F5 完成时间:18:42 PNEUE MacBook Air F6 F7 DII F8 tv 8 F9 F10 F
Create Python programming in Physics and Materials Science. In physics, chemistry, and materials science, percolation refers to the movement and filtering of fluids through porous materials. (Wikipedia.org). Consider a simplified model below. Imagine, this is a filter or maybe some layers of stones such that when a certain amount of fluid is put on top, it will reach the bottom only if there is a direct passage. In this case, the blue squares serve as the porous materials or the holes where fluid may pass. Your task is to simulate this simple percolation by representing them in a 2-dimensional array. The input would be in a string, while the output would either be yes or no to indicate whether the fluid can pass through the filter or not. Examples: Input: “1,0,0,0,0;0,1,0,0,0;0,1,0,0,0;0,0,1,0,0;0,0,0,1,0”Output: Yes Input: “0,0,0,1,0;0,1,0,0,0;0,1,0,0,0;0,0,1,0,0;0,0,0,1,0”Output: No Input: “1,0,0;0,1,0;0,0,0;0,0,1”Output: No Note: It should also work with these two inputs:1. “1”…

THIS NEEDS TO BE DONE IN C#!! The Tourtise and The Hair In this lab, we will be simulating the classic race of the tourtise and the hare. The race will take place on two paths of 70 tiles, which spans from left to right. The path will have two lanes, one for each animal. The path will be represented as an array of 70 characters, where each character will be the following: · A dash(i.e, “-“), which represents an empty tile. · An “h”, which represents the hare on the hare lane. · A “t”, which represents the tourtise on the tortise lane. All tiles will be “empty” (i.e. set to the dash) with the exception of the tiles that are occupied by the animals. As the animals move, the previous tile the animal was on will be set to empty, and the new tile will be changed to either “h” or “t”. Tile 70 will be the finishing tile, and the first animal to that tile will be declared the winner of the race. We will use randomization to determine how far each animal will move. Since this race will be…
this code should be in python: you will be implementing a simple Tic-Tac-Toe game without the graphics.Here is how it works: • First, it is randomly determined if the user starts the game or the computer and thisinformation is shown to the user. The player who starts always starts as “X”.• The players (computer and the user) will then take turns in playing. The computer willchoose a random empty spot on its turn. The user enters its choice in the console.• Each of the empty spots have a corresponding number that the players choose on theirturn. If the user enters anything other than the number of an empty spot (not yet filledwith “X” or “O”), it will not be accepted, and they will be prompted to enter a correctnumber. • After each turn, two things need to be done: 1) displaying the updated board 2) checkingif anyone has…
Please do this in Python Programming Scenario As you probably know, Sudoku is a number-placing puzzle played on a 9x9 board. The player has to fill the board in a very specific way: each row of the board must contain all digits from 0 to 9 (the order doesn't matter) each column of the board must contain all digits from 0 to 9 (again, the order doesn't matter) each of the nine 3x3 "tiles" (we will name them "sub-squares") of the table must contain all digits from 0 to 9. If you need more details, you can find them here. Your task is to write a program which: reads 9 rows of the Sudoku, each containing 9 digits (check carefully if the data entered are valid) outputs Yes if the Sudoku is valid, and No otherwise. Test your code using the data we've provided. Test data Sample input: 295743861 431865927 876192543 387459216 612387495 549216738 763524189 928671354 154938672 Sample output: Yes Sample input: 195743862 431865927 876192543 387459216 612387495 549216738 763524189 928671354…
Write a program to calculate the surface area and volume of a square pyramid. A square pyramid has a base that is square and all triangle faces are congruent isosceles triangles. (An isosceles triangle is a triangle in which two of the sides are equal. Length of the base: a Height of the pyramid: h Volume = a2h/3 Slant height, s = sqrt(h2 + (a/2)2) This is the Pythagorean Theorem part. Area of one pyramid side = s*a/2 Here are my calculations: Test Case #1 Height(h): 5.0’ Base(a): 2.5’ Volume = (2.5**2) * (5/3) (6.25) * (1.66) = 10.375 cubic feet Slant Height = math.sqrt(5**2) + (2.5/2)**2) Sqrt(25+1.5625) Sqrt(26.5625) = 5.154 feet Pyramid (not including base) = (5.154) * (2.5/2) * 4 (5.154) * (1.25) * (4) = 25.769 sq. Ft. I have attached a screenshot of my program I have so far. When I run the program, the output doesn't match what I have for the surface area and volume, am I missing something?

Length of the base: a Height of the pyramid: h Volume = a2h/3 Slant height, s = sqrt(h2 + (a/2)2) This is the Pythagorean Theorem part. Area of one pyramid side = s*a/2 For this program you are to determine two things about a square pyramid. 1) the surface area of the four sides. 2) the volume. Do not include surface area of the base. Test case 1: Height: 5.0' Base: 2.5' Test case 2: Height 2.5 Base: 4.3' The program asks the user to enter the pyramid height (in feet) and length of the base (in feet). Your program will need to determine surface area, and volume by using pythagorean theorem. Your output should neatly show the height, base, total surface area, and volume of the pyramid using 33 decimal place of…
