Classes for each of the 50 U. S. states, including California, NewYork, and Texas have a parent class named State. The State class needs to declare a method called getAbbreviation() that returns the U. S. Postal Service abbreviation (CA, IL, NY, etc.) for a represented state. The State class itself, however, represents a concept that does not have an abbreviation and should not provide its own implementation of the method. The child classes of State will inherit and be forced to implement getAbbreviation(). It is important that the State class provides some sort of method declaration so that the following code works. State s = new Florida(); System. out. println(s. getAbbreviation()); State t = new Alaska(); System. out. println(t. getAbbreviation()); Which of the following code fragments for the State class provides the best declaration of the getAbbreviation() method for this situation?

Acomputer is a multipurpose device that accepts input, processes data, stores data, and produces output, all according to a series of stored . the processing unit of most modern computers is a(n) . the instructions that tell a computer how to carry out a task are referred to as computer , which are distributed as software. computers run three main types of software: software, system software, and development tools. an example of system software is a computer system, which is essentially the master controller for all the activities that a digital device performs. digital devices are constructed using tiny electronic components that represent data bits as electrical signals. the system unit houses the system board, which contains several circuits made from semiconducting materials. computers come in three popular form factors: component, , and slate. many of today's digital devices operate on battery power supplied by ion batteries. battery life and lifespan can be extended by following good battery management practices.

Write a function named printfloatrepresentation(float number) that will print the floating point representation of a number using the format given below. (sign bit) exponent in binary (assumed bit).significandfor example if the number passed an argument is 71 yourprogram should print (0) 10000101 (1).00011100000000000000000similarl y if the number passed to the function as argument is -71 the program should print (1) 10000101 (1).00011100000000000000000

The volume v and paper surface area a of a conical paper cup are given by where r is the radius of the base of the cone and h is the height of the cone. a. by eliminating h, obtain the expression for a as a function of r and v. b. create a user-de ned function that accepts r as the only argument and computes a for a given value of v. declare v to be global within the function. c. for v ! 10 in.3 , use the function with the fminbnd function to compute the value of r that minimizes the area a. what is the corresponding value of the height h? investigate the sensitivity of the solution by plotting v versus r. how much can r vary about its optimal value before the area increases 10 percent above its minimum value?
