An argument is expressed in English below. The domain is the set of people attending a party. Every person who was late to the party left the party early. There is a person who was late to the party and was not happy. . There is a person who left the party early and was not happy. The form of the argument is: vx (P(x) → Q(x)) 3X (P(x) ^ -R(x)) .: 3X (Q(x) ^ ¬R(x)) Select the definitions for predicates P, Q, and R. P(x): Pick Q(x): Pick R(x): Pick

Cone is a three-dimensional structure having a circular base where a set of line segments, connect all of the points on the base to a common point called apex. A cone can be seen as a set of non-congruent circular discs that are stacked on one another such that ratio of the radius of adjacent discs remains constant. The area is a cone is computed as A = (s sin(x))? where, "s" is the slant and "x" is the angle in radian. Write a C++ program that computes the area A of Cone by reading its parameter from a text file "input.txt". Each line of the file represents the Cone name, the slant "s" and the angle "x" of a Cone, respectively. The program should read each line to compute the area A of each Cone. It should also display the minimum computed area. Your program should implement the following functions: Area(): This function receives the values of "s", and "x" then computes and ng9 returns the value of area A. Print(): This function receives the name of Cone and the computed area A then…

Transcribed Image Text Elon Musk is running the graph construction business. A client has asked for a special graph. A graph is called special if it satisfies the following properties: • It has <105 vertices. It is a simple, undirected, connected 3-regular graph. It has exactly k bridge edges, (k given as input). For a graph G, define f(G) to be the minimum number of edges to be removed from it to make it bipartite. The client doesn't like graphs with a high value of f, so you have to minimize it. If there doesn't exist any special graph, print –1. Otherwise, find a special graph G with the minimum possible value of f(G) and also find a subset of its edges of size f(G) whose removal makes it bipartite. In case there are multiple such graphs, you can output any of those. Elon has assigned this task to you, now vou have to develon a C++ code that takes bridge edges as innut and print all the possible granhs
Code in C++ only. Correct answer will upvoted else downvoted. framework of size n×m, with the end goal that every cell of it contains either 0 or 1, is considered lovely if the total in each adjoining submatrix of size 2×2 is actually 2, i. e. each "square" of size 2×2 contains precisely two 1's and precisely two 0's. You are given a network of size n×m. At first every cell of this network is unfilled. How about we indicate the cell on the crossing point of the x-th line and the y-th segment as (x,y). You need to handle the inquiries of three sorts: x y −1 — clear the cell (x,y), in case there was a number in it; x y 0 — compose the number 0 in the cell (x,y), overwriting the number that was there already (assuming any); x y 1 — compose the number 1 in the cell (x,y), overwriting the number that was there beforehand (assuming any). After each question, print the number of ways of filling the unfilled cells of the grid so the subsequent network is delightful. Since the appropriate…
Programming homework1) Simulated waiting queue in an Indian post office: In an Indian post office that not only distributes mail but also performs some financial activities like a savings bank, a lone postal worker attends to a single lineup of clients. As soon as a consumer enters the line, they are given a token # (serial number). After receiving assistance, the consumer exits the queue while the postal worker receives the token back. The employee could inquire as to how many consumers are still unattended at any one time.i) Put the system into practise using a suitable queue data structure, simulating the arrival and departure of consumers at random when the service is finished.

∑ = {C,A,G,T}, L = { w : w = CAjGnTmC, m = j + n }. For example, CAGTTC ∈ L; CTAGTC ∉ L because the symbols are not in the order specified by the characteristic function; CAGTT ∉ L because it does not end with C; and CAGGTTC ∉ L because the number of T's do not equal the number of A's plus the number of G's. Prove that L ∉ RLs using the RL pumping theorem.
