Why are multiple NAND gates used to replace other single function gates? Select one: a. NAND gates are packaged more densely on IC's than other types of gates. b. It is easier to design logic circuits with a single gate type, since you only have to fully understand how one type of gate works. c. NAND gates are cheaper than any other type of gate. d. It makes it possible to use spare portions of NAND IC packages to implement other logic functions, perhaps reducing the total IC package count.

Anul 2017 tocmai s-a încheiat, suntem trişti deoarece era număr prim, însă avem şi o veste bună, anul 2018 este produs de două numere prime, 2 şi 1009. dorel, un adevărat colecţionar de numere prime, şi-a pus întrebarea: “câte numere dintr-un interval [a,b] se pot scrie ca produs de două numere prime? “.

8. create an abstract student class for parker university. the class contains fields for student id number, last name, and annual tuition. include a constructor that requires parameters for the id number and name. include get and set methods for each field; the settuition() method is abstract. create three student subclasses named undergraduatestudent, graduatestudent, and studentatlarge, each with a unique settuition() method. tuition for an undergraduatestudent is $4,000 per semester, tuition for a graduatestudent is $6,000 per semester, and tuition for a studentatlarge is $2,000 per semester. write an application that creates an array of at least six objects to demonstrate how the methods work for objects for each student type. save the files as student.java, undergraduatestudent.java, graduatestudent.java, studentatlarge.java, and studentdemo.java.
