Answer:
True.
Explanation:
Software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications.
Some of the models used in the software development life cycle (SDLC) are; waterfall model, incremental model, spiral model, agile model, big bang model, and V-shaped model.
The five (5) standard stages of development in software development are;
I. Analysis.
II. Design.
III. Implementation (coding).
IV. Testing.
V. Maintenance.
The SDLC is cyclical in nature, meaning that any of the five stages can be revisited at any time during a project. This is possible because the stages of development are not performed only once but recurring at regular intervals.

Answer:
Option A, initiative
Explanation:
Initiation is an art of performing an act or task by self motivation rather on command or instruction from anyone.
Insubordination is incorrect as here there is no mentioning of disobeying seniors or authority
Also, courage and power means having strength to perform any task. Here action is performed without any instruction and it in no sense signifies a brave deed.
Hence, option A is correct

Complete Question:
A teacher is writing a code segment that will use variables to represent a student's name and whether or not the student is currently absent. Which of the following variables are most appropriate for the code Segment?
Group of answer choices.
А. A string variable named s and a Boolean variable named a.
B. A string variable named s and a numeric variable named A.
С. A string Variable named studentName and a Boolean variable named isAbsent.
D. A string Variable named studentName and a numeric variable named absences.
Answer:
C. A string variable named studentName and a Boolean variable named isAbsent.
Explanation:
In Computer programming, a variable stores information which is passed from the location of the method call directly to the method that is called by the program.
In this scenario, teacher is writing a code segment that will use variables to represent a student's name and whether or not the student is currently absent.
Hence, the variables which are most appropriate for the code segment are a string variable named studentName and a Boolean variable named isAbsent.
Basically, the string variable named studentName would only accept or hold values that are alphabetic but not numerical value. Thus, the variable studentName would represent the name of a specific student.
Also, the Boolean variable named isAbsent would accept values that are either "True" or "False" because it works on the principle of Boolean logic (0 for false and 1 for true).

A pointer is nothing but a memory location where data is stored. A pointer is used to access the memory location. There are various types of pointers such as a null pointer, wild pointer, void pointer and other types of pointers. When you want to deal different variable data type, you can use a typecast void pointer.
Write a method that takes two circles, and returns the sum of the areas of the circles.
This method must be named areaSum() and it must have two Circle parameters. This method must return a double.
For example suppose two Circle objects were initialized as shown:
Circle circ1 = new Circle(6.0);
Circle circ2 = new Circle(8.0);
The method call areaSum(circ1, circ2) should then return the value 314.1592653589793.
You can call your method in the program's main method so you can test whether it works, but you must remove or comment out the main method before checking your code for a score.
Answer:
public static double areaSum(Circle c1, Circle c2){
double c1Radius = c1.getRadius();
double c2Radius = c2.getRadius();
return Math.PI * (Math.pow(c1Radius, 2) + Math.pow(c2Radius, 2));
public static void main(String[] args){
Circle c1 = new Circle(6.0);
Circle c2 = new Circle(8.0);
areaSum(c1,c2);
}
Explanation:
The function calculates the sum of the area of two circles with their radius given. The program written in python 3 goes thus :
import math
#import the math module
def areaSum(c1, c2):
#initialize the areaSum function which takes in two parameters
c1 = math.pi * (c1**2)
# calculate the area of the first circle
c2 = math.pi * (c2**2)
#Calculate the area of the second circle
return c1+c2
#return the sum of the areas
print(areaSum(6.0, 8.0))
A sample run of the program is attached

2. Read the following scenarios about how three different programmera approach
programming a computer game. Identify which type of programming design
approach each represents (3 points):
a) Yolanda first breaks down the whole game she needs to program into modules.
She then breaks these modules into smaller modules until the individual parts are
manageable for programming. She writes the smallest modules, and then
recombines them into larger parts.
b) Isabella takes the game process and groups together sets of related data involved
in the process. She then identifies the messages the data should respond to. After
writing the code for each set of data, Isabella then combines, tests, and refines the
subsets until the software runs properly
a.) Structured programming
b.) Object-oriented programming
c.) Top-down programming
The programming design approach represented in this scenario is modular programming. The programming design approach represented in this scenario is object-oriented programming.
What is programming?The process of creating a set of instructions that tells a computer how to perform a task is known as programming.
Computer programming languages such as JavaScript, Python, and C++ can be used to create programs.
Modular programming is the programming design approach represented in this scenario.
Yolanda divides the entire game into modules, which are then subdivided further into smaller modules until the individual parts are manageable for programming.
Object-oriented programming is the programming design approach represented in this scenario. Isabella organizes sets of related data and determines which messages the data should respond to.
Thus, this method entails representing data and functions as objects and employing inheritance and polymorphism to generate flexible and reusable code.
