Let r be a robotic arm with a fixed base and seven links. the last joint of r is a prismatic joint, the other ones are revolute joints. give a set of parameters that determines a placement of r. what is the dimension of the configuration space resulting from your choice of parameters?

Design a class tictactoe that: holds the following information about the game: two-dimensional array (3 by 3), and winner. add additional variables as needed. includes the functions to perform the various operations on objects. for example, function to print the board, getting the move, checking if move is valid, determining if there is a winner after each move. add additional operations as needed. includes constructor(s). write the functions of the class, and write a program that uses the class. the program should declare an object of type tictactoe. the program will create the board and store it in the array. the program will allow two players to play the tic-tac-toe game. after every valid move update the array, check if there is a winner. if there is no winner and no tie, then print the board again to continue.

4.9: population write a program that will predict the size of a population of organisms. the program should ask the user for the starting number of organisms, their average daily population increase (as a percentage, expressed as a fraction in decimal form: for example 0.052 would mean a 5.2% increase each day), and the number of days they will multiply. a loop should display the size of the population for each day. prompts, output labels and messages.the three input data should be prompted for with the following prompts: "enter the starting number organisms: ", "enter the daily increase: ", and "enter the number of days the organisms will multiply: " respectively. after the input has been read in successfully, a table is produced, for example: 2 300.0 4 675.0 under the heading is a line of 29 dashes followed by one line for each day, showing the day number and the population at the beginning of that day. input validation.do not accept a number less than 2 for the starting size of the population. if the user fails to satisfy this print a line with this message "invalid. must be at least 2. re-enter: " and try to read the value. similarly, do not accept a negative number for average daily population increase, using the message "invalid. enter a non-negative number: " and retrying. finally, do not accept a number less than 1 for the number of days they will multiply and use the message "invalid. enter 1 or more: ".
