A four-pole induction motor drives a load at 2549 rpm. This is to be accomplished by using an electronic converter to convert a 400-V dc source into a set of three-phase ac voltages. Part A Find the frequency required for the ac voltages assuming that the slip is 4 percent. Part B If the dc-to-ac converter has a power efficiency of 93 percent and the motor has a power efficiency of 80 percent, estimate the current taken from the dc source.

1. Dr. Gulakowicz is an orthodontist. She estimates that adding two new chairs will increase fixed costs by $150,000, including the annual equivalent cost of the capital investment and the salary of one more technician. Each new patient is expected to bring in $3,000 per year in additional revenue, with variable costs estimated at $1,000 per patient. The two new chairs will allow Dr. Gulakowicz to expand her practice by as many as 200 patients annually. How many patients would have to be added for the new process to break even?

3. Boring Array Array operations are boring and fun! You are given two arrays of integers a 1 ,a 2 ,,a n a and b 1 ,b 2 ,,b n . Let's define a transformation of the array a : Choose any non-negative integer k such that 0kn . Choose k distinct array indices Add 1 to each of a i1 ,a i2 ,,a ik , all other elements of array a 1 remain unchanged. Permute the elements of array a in any order. Is it possible to perform some transformation of the array a exactly once, so that the resulting array is equal to b? Function Description Complete the function trans formArray in the editor below. trans formArray should return True if array a can be transformed into array b by the operation mentioned above, otherwise, return me formarray has the following parameter(s): a: a string representing array, each element is separated by space b: a string representing array, each element is separated by space Constraints - n(1n10 6 ) - a 1 ,a 2 ,,a n (10 6 a i 10 6 ) - b 1 ,b 2 ,,b n (10 6 b i 10 6 ) Input Format For Custom Testing - Sample case 0 Sample input 42340 12345 1>101/b in/python 3 13 * Complete the 'transionmarray' funct 14 The function is expected to return. 16 * The runction 17 2.
