Question 31 A survey on pollution has been conducted on four cities. The degree of pollution is classified as not polluted, moderately polluted, and heavily polluted. The results of the survey are illustrated in the table below: City city1 city2 city3 city4 Xi1: not polluted 0.3 0.2 0.1 0.7 X12: moderately polluted 0.4 0.2 0.4 0.2 Xi3: heavily polluted 0.3 0.6 0.5 0.1 Use the cosine amplitude method to develop the fuzzy relation R that relates the pollution degree to the city.

Ten members of Math Club are driving to a math conference in a neighboring state. However, some of these students have dated in the past, and things are still a little awkward. Each student lists which other students they refuse to share a car with; these conflicts are recorded in the table below. What is the fewest number of cars the club needs to make the trip? Do not worry about running out of seats, just avoid the conflicts. Student: A B C D Conflicts: BEJ ADG HJ BF E AI F DJ G H B CI I EHJ J ACFI

QUADRATIC PRIMES This question is adopted from Project Euler Question 27. (https://projecteuler.net/problem=27) The quadratic formula n^2 + n + 41 will produce 40 primes for consecutive integer values 0 <= n <= 39. However, when n = 40, this formula will not generate a prime number. Another interesting quadratic formula n^2 – 79n + 1601 produces 80 prime numbers for consecutive values 0 <= n <= 79. The Question: find a and b such that when -999 <= a <= 999 and -1000 <= b <= 1000, the quadratic form ?^2 + ? × ? + ? produces the maximum number of primes for consecutive values of n, starting with n = 0. Requirement: MUST BE WRITTEN IN C++ - Print the 40 primes generated by formula n 2 + n + 41 - Print the 80 primes generated by formula n 2 – 79n + 1601 - Write a function that takes in an integer and returns whether the given number is prime or not. - Output the value of a, b and how many consecutive values of n (count the starting zero!) can be generated. - Submit…

Question-2: A pyramids are discovered, each has a triangular base with equal sides. An n meters high pyramid is constructed by forming n layers of triangles using Im cubical stones. Then layers are stacked on top of each other. The first layer is the triangle with n meters base, on top, n-1 meters base, until the top level which has only 1 stone. You are asked to calculate the number of stones needed to build a pyramid with the height n. WAIT! We just discovered that some pyramids have a secret room inside. This room is also of the same shape and structure as the pyramid with m layers of stones removed. In order for the room to be secret, m

A6. Suppose a farmer decided to keep individual records for the new cattle. His records show 4 bred heifers valued at $900; 5 cows valued at $1,000, and 1 bull valued at $2,000. Using the chart below, setup the individual records for each animal for year 1. Make sure that your animal ID for each type of animal is different, for example, bred heifers can start at 22-1, etc.; cows can start at 22- 01, and the bull can be 22-001.
