The coordinates of centres of these squares are (x1, a/2), (x2, a/2) and (x3, a/2) respectively. All of them are placed with one of their sides resting on the x-axis. You are allowed to move the centres of each of these squares along the x-axis (either to the left or to the right) by a distance of at most K. Find the maximum possible area of intersections of all these three squares that you can achieve. That is, the maximum area of the region which is part of all the three squares in the final configuration. Note: Please Answer in python only Input 1 10 123 Output 0.00000
Suppose that you want to calculate 1434661 · 3785648743 − 100020304 · 54300201. You are told thatthe answer is a positive integer less than 90. Compute the answer mod 10 and mod 9, then combineto get the answer. Show all the necessary work to obtain your answers. Note: This technique hasoften been employed to do calculations with large integers because most of the computations use smallintegers, with only the Chinese Remainder Theorem step requiring large integers. For example, if theanswer is known to be less than 1036, the calculations can be done mod p for each prime less than100. Since the product of the primes less than 100 is approximately 2.3 × 1036, the Chinese RemainderTheorem gives the answer exactly
