JS Write a function named "distance" that takes two floating point numbers as parameters representing the (x, y) coordinates of a point in a 2d space. Define your distance method to return the Euclidean distance between the input point and the point (-2.2, -7.7). (For those who may not remember, the Euclidean distance between a point (p, P2) and a point (91, 92) is equal to: d(p, q) = V(41 - P1)² + (42 – P2)².)

Write a function called acronym that takes as a parameter a string containing a phrase and that returns a string that has the acronym for the phrase.  For example, the following call:         acronym("self-contained underwater breathing apparatus") should return "SCUBA".  The acronym is formed by combining the capitalized first letters of each word in the phrase.  Words in the phrase will be separated by some combination of dashes and spaces.  There might be extra spaces or dashes at the beginning or end of the phrase.  The string passed as a parameter will not contain any characters other than dashes, spaces, and letters, and is guaranteed to contain at least one word.  Below are several sample calls. Function call Value returned acronym("   automatic   teller   machine  ")        "ATM" acronym("personal identification number") "PIN" acronym("computer science")                         "CS" acronym("merry-go-round") "MGR" acronym("All my Children")…

Use Python for this question. Also, could you please comment/explain what each line of code represents in this question.   Write a function piggyBank that accepts a sequence of "coins" and returns counts of the coins and the total value of the bank. the coins will be given by a list of single characters, each one of 'Q','D','N',P' , representing quarter, dime, nickel, penny the function returns a tuple with two items: a dictionary with counts of each denomination. They should always be listed in the order 'Q','D','N',P' the total value in whole cents of the amount in the bank   Output for this question is shown in the attached image

Write a function called isValidLength that takes an integer number and returns true if the number has a valid length and false otherwise. Valid- length is determined by finding number length. If the length is at least 3 digits and at most 5 digits, then the number has a valid length. For example, the number 324 is valid because it's 3 digits long and the number 22 is invalid because it’s 2 digits long.
