- Interesting, intersecting def squares_intersect(s1, s2): A square on the two-dimensional plane can be defined as a tuple (x, y, r) where (x, y) are the coordinates of its bottom left corner and r is the length of the side of the square. Given two squares as tuples (x1, y1, r1) and (x2, y2, r2), this function should determine whether these two squares intersect, that is, their areas have at least one point in common, even if that one point is merely the shared corner point when these two squares are placed kitty corner. This function should not contain any loops or list comprehensions of any kind, but should compute the result using only integer comparisons and conditional statements. This problem showcases an idea that comes up with some problems of this nature; it is actually far easier to determine that the two squares do not intersect, and negate that answer. Two squares do not intersect if one of them ends in the horizontal direction before the other one begins, or if the same…Write a function in C programming language that gets two ints x and y, and returns the sum of all ints between x and y, including them. int sum_interval(int x, int y); For example: - sum_interval(1, 4)returns 1+2+3+4=10. - sum_interval(10, 3)returns 3+4+5+6+7+8+9+10=52. - sum_interval(2, -1)returns (-1)+0+1+2=2. - sum_interval(-1, -1)returns -1. Note that we may have x>=y or x<=y. You may assume that the sum will be within the range of int.Write a function that receives 3 assignment grades, a1, a2, a3, and a final grade, f, for a student and returns the corresponding letter grade of the student. The weights for the assignments and the final are 0.2, 0.2, 0.2, and 0.4, respectively. You can use the following table for matching grades to letters: 95-100 -> A1 90-94 -> A2 85-89 -> A3 80-84 -> B1 75-79 -> B2 70-74 -> B3 65-69 -> C1 60-64 -> C2 55-59 -> C3 40-54 -> D 0-39 -> F For example, compute_letter(80, 60, 40, 70) returns "C2" because 80 * 0.2 + 50 * 0.2 + 40 * 0.2 + 70 * 0.4 = 62 and 62 corresponds to C2. Note that, you are expected to do rounding. For example, 39.4 is F, whereas 39.5 is D. You can use the builtin round() function for this. Please google this function and learn how to use it. """

- It is good practice to plot the integrand function to check whether it is “well behaved” before you attempt to integrate. Singularities (i.e. x values where the f(x) tends towards minus or plus infinity) or other irregular behaviour (such as f(x) = sin( 1 x ) close to x = 0 are difficult to handle numerically. 1. Write a function with name plotquad which takes the same arguments as the quad command (i.e. f , a and b) and which • (i) creates a plot of the integrand f(x) and • (ii) computes the integral numerically using the quad function. The return values should be as for the quad function.Write a function called number_matrix(r,c) that takes two parameters r and c and PRINTS ON THE SCREEN a matrix of numbers as follows: 1 2 3 4 5 .... 2 3 4 5 6 .... 3 4 5 6 7 .... ... In this pattern, each row contains c numbers and there are r rows. For example, number_matrix(4,3) results in: 1 2 3 2 3 4 3 4 5 4 5 6Pb#1: For several values of x, confirm that eix = cos x + i sin x Pb#2: An object thrown vertically with a speed vo reaches a height h at time t, where h= vo*t - gt2 Write and test a function that computes the time t required to reach a specified height h, for a given value of vo. The function's inputs should be h, vo, and g. Test your function for the case where h=100 m, vo=50 m/s. and g=9.81 m/s2. Interpret both answers. (MATLAB)
- An arcade game player wants to climb to the top of the leaderboard and track their ranking. The game uses Dense Ranking, so its leaderboard works like this: The player with the highest score is ranked number on the leaderboard. Players who have equal scores receive the same ranking number, and the next player(s) receive the immediately following ranking number. Example The ranked players will have ranks , , , and , respectively. If the player's scores are , and , their rankings after each game are , and . Return . Function Description Complete the climbingLeaderboard function in the editor below. climbingLeaderboard has the following parameter(s): int ranked[n]: the leaderboard scores int player[m]: the player's scores Returns int[m]: the player's rank after each new score Input Format The first line contains an integer , the number of players on the leaderboard.The next line contains space-separated integers , the leaderboard scores in decreasing order.The next…Using R: Write a function simulatePlanes() that takes in as input a number of days and a logical value determining whether you want tothe plot or not.
