Show all work on your piece of paper. Find the height of the isosceles triangle using the Pythagorean Theorem. The drawing is not to scale. 

The following diagram represents an ATM class that’s used to represent ATM devices that are part of a bank’s ATM system.  The attributes are data items the ATM must store about its own state and are needed to support the usual operation of withdrawing cash.  The methods are the ATM’s behaviors, or operations, needed to support the withdrawal operation.  Which of the following methods must be added to fully support that operation?  Select the one best choice.    

A class definition called Property is given below.  Create code for a method that displays a brief description of the property when the Python print function prints the object id of the property.  The “__size” and “__value” attributes are integer values, the other attributes are strings.  class Property ( ):        def __init__(self, name, propID, loc, size, value, owner): self.__name = name                self.__propID = propID                self.__loc = loc                self.__size = size self.__value = value                self.__owner = ownerFor example, when this code is executed: p1 = Property(‘Private Res.’, ‘FX0042’, ‘9900 University Dr’, 9500, 765000, ‘Maria Muellerl’) ……the code print(p1) displays this: Name: Private Res. Property ID: FX0042 Location: 9900 University Dr Size: 9500 sq ft Value: $765000 Owner: Maria Mueller

Which of the lines below will be in the display output of the following global code if executed after the above class definitions have already been executed?  Check all that will be displayed. Ed = Horse (‘Mr. Ed’, ‘land’) Moby = Whale (‘Moby Dick’, ‘ocean’) Monty = Snake (‘Python’, ‘ground’) Angie = Eagle (‘Angeline’, ‘air’) Orca = Whale (‘Killer’, ‘ocean’) for animal in (Ed, Monty, Angie, Orca):           animal.moves( )

Create a new class called ContactList that is a sublcass of the built-in ‘list’ class, but ensures items added to the class fit the pattern of an email address.  Assume that items can only be added to the subclass via the append and insert methods, and not when the constructor creates objects.  Specifically, the data parameter provided to the methods must be (1) a type string, (2) at least 15 characters long, (3) not already appear in the list, (4) include the string “@”, and (5) end with the string “.com” (dot-com) in the usual place of an email address.  Use the string method “endswith()” to detect number (5).  That method matches the ending of a string with the given parameter and returns True if they match.  Write the code for the ContactList subclass to be consistent with the above definition.  Return True when an item is successfully added, otherwise return False.
