Write three static comparators for the any Point2D data type , one that compares points by their x coordinate, one that compares them by their y coordinate, and one that compares them by their distance from the origin. Write two non-static comparators for the Point2D data type, one that compares them by their distance to a specified point and one that compares them by their polar angle with respect to a specified point.

Ball at the wallcontext In a ball-at-the-wall game, children in the schoolyard must throw balls at the school wall to reach lines placed at certain heights. You want to predict how high the ball will hit the wall based on the parameters of the throw. Constraints and information The children are all placed behind a line drawn on the floor, at a known horizontal distance ? from the wall;The initial height at which the ball leaves the child's hand is known;The speed and angle of the throw are known; Modelization Creates a model to determine how high the ball will hit the wall based on the children's distance from the wall and the height, speed and angle of the ball as it leaves the child's hand . Then test your model with the following parameters Distance between the wall and the child: 3.9?; Height of the ball when it leaves the child's hand: 1.05?; Throw Speed: 14.1?/?; Throw angle: 51∘

Ql: The Collatz conjecture function is defined for a positive integer m as follows. (COO1) g(m) = 3m+1 if m is odd = m/2 if m is even =1 if m=1 The repeated application of the Collatz conjecture function, as follows: g(n), g(g(n)), g(g(g(n))), ... e.g. If m=17, the sequence is 1. g(17) = 52 2. g(52) = 26 3. g(26) = 13 4. g(13) = 40 5. g(40) = 20 6. g(20) = 10 7. g(10) = 5 8. g(5) = 16 9. g(16) = 8 10. g(8) = 4 11. g(4) = 2 12. g(2) = 1 Thus if m=17, apply the function 12 times in order to reach m=1. Use Recursive Function.

Tyger Valley Pet Shelter (TVPS) receives food donations from a group of pet food manufacturers. TPS relies on each manufacturing company for a particular need. For example, Veggie Land supplies all the vegetables and Premier Seed Suppliers supplies all the seeds. The different food types are allocated to the animals according to their category. For example, food type 'seeds' is allocated to category 'Birds', while food type 'vegetables' is allocated to the categories 'Mammals' and 'Birds'. Each animal category is subdivided into different pet types. For example, the mammal record could relate to pet types 'Dog' and 'Cat'. TPS has recruited you to be their database designer. The database will store information on their suppliers, food types, animal categories and pet types: Record a unique ID, company name, contact number and possibly an e-mail address for each manufacturer. When recording information about the different food types, ensure that the expiry date is also stored. When…
Correct answer will be upvoted else downvoted. Computer science. example of a chainword is the accompanying triple: a line of m lowercase Latin letters; the main clue: an arrangement of fragments with the end goal that the letters that compare to each portion spell a word from the word reference; the subsequent clue: one more succession of portions with the end goal that the letters that relate to each section spell a word from the word reference. Note that the successions of portions don't really need to be unmistakable. Two occasions of chainwords are considered unique on the off chance that they have various strings, diverse first clues or distinctive second clues. Count the number of various examples of chainwords. Since the number may be really huge, output it modulo 998244353. Input The primary line contains two integers n and m (1≤n≤8, 1≤m≤109) — the number of words in the word reference and the number of letter cells. Every one of the following n…
