Textbook Question

Chapter 4, Problem 4.5PE

(Geometry: area of a regular polygon) A regular polygon is an n-sided polygon in which all sides are of the same length and all angles have the same degree (i.e., the polygon is both equilateral and equiangular). The formula for computing the area of a regular polygon is

A r e a = n × s 2 4 × tan ( π n )

Here, s is the length of a side. Write a program that prompts the user to enter the number of sides and their length of a regular polygon and displays its area. Here is a sample run:

When the FCC added Color Television to the Industry Standards, they went with the system developed in the 1940s by Peter Goldman for CBS. Question 15 options: True False Part of the reason that many critics disliked 1950s gameshows was the fact that gameshows offered one of the few opportunities to see unscripted interactions with "real" (average/non-famous) people on television. Question 16 options: True False The Andy Griffith Show is an example of the "rural revival" shows that become enormously popular on 1960s American television. Question 19 options: True False During the Network Era, the hours before primetime each day were exclusively devoted to locally-produced programming, not programming dictated by an affiliate station's parent network. Question 20 options: True False

Although color television was not added to the industry standard until 1956, CBS had been broadcasting selected special events in color as early as 1950. Question 1 options: True False Two key factors in creating the Network Era of American television were the FCC licensing freeze and ______________. Question 4 options: The Quiz Show Scandals Habitual Viewing Operation Frontal Lobes Drop-In Viewing Least Objectionable Programming was designed to embrace the public service-oriented vision of using television to elevate mass culture and enrich viewers. Question 6 options: True False By the end of the 1950s, all three remaining networks (NBC, CBS, & ABC) were broadcasting their entire nightly programming schedule in full color. Question 9 options: True False

7. See the code below and solve the following. public class Test { public static void main(String[] args) { int result = 0; } result = fn(2,3); System.out.println("The result is: + result); // fn(x, 1) = x // fn(x, y) = fn(x, y-1) + 2, when y>1 public static int fn(int x, int y) { if (x <= 1) return x; else return fn(x, y-1) + 2; } } 7-1. This program has a bug that leads to infinite recursion. Modify fn(int x, int y) method to fix the problem. (2 point) 7-2. Manually trace the recursive call, fn(2,3) and show the output (step by step). (2 point) 7-3. Can you identify the Base Case in recursive method fn(int x, int y)? (1 point)
