Power amplifier stages in a real circuit. Circuit diagram of a three stage practical audio power amplifier is shown in the figure below. Small signal transistor Q1 and its associated components form the voltage amplification stage.
Answer:
Generally you should pick an amplifier that can deliver power equal to twice the speaker's program/continuous power rating. This means that a speaker with a “nominal impedance” of 8 ohms and a program rating of 350 watts will require an amplifier that can produce 700 watts into an 8 ohm load.
The function leap n, which takes an integer n as input, and returns True if the year n is a leap year, and False otherwise. NOTE: Please provide function declaration [2 marks]. Leap years are those that are evenly divisible by 4, except any year that is also evenly divisible by 100 unless that year is also evenly divisible by 400. So, for example, 1996, 2012, and 2020 are all leap years, but 2100, 2200, and 2300 are not leap years, because although they are all evenly divisible by 4, they are also evenly divisible by 100. However, 1600, 2000, and 2400 are leap years, because although they are divisible by 100, they are also divisible by 400. The Haskell interaction may look like: > leap 1996 True > leap 2000 True > leap 2100 False
Answer:
Explanation:
The following code snippet is a leap year checker written in Haskell which checks to see if the year is a leap year and then outputs a boolean value.
isDivisibleBy :: Integral n => n -> n -> Bool
isDivisibleBy x n = x `rem` n == 0
leap_n :: Integer -> Bool
leap_n year
| divBy 400 = True
| divBy 100 = False
| divBy 4 = True
| otherwise = False
where
divBy n = year `isDivisibleBy` n
When the function below is called with 1 dependent and $400 as grossPay, what value is returned?
double computeWithholding (int dependents, double grossPay)
{
double withheldAmount;
if (dependents > 2)
withheldAmount = 0.15;
else if (dependents == 2)
withheldAmount = 0.18;
else if (dependnets == 1)
withheldAmount = 0.2;
else // no dependents
withheldAmount = 0.28;
withheldAmount = grossPay * withheldAmount;
return (withheldAmount);
}
a. 60.0
b. 80.0
c. 720.0
d. None of these
Answer:
b. 80.0
Explanation:
Given
[tex]dependent = 1[/tex]
[tex]grossPay = \$400[/tex]
Required
Determine the returned value
The following condition is true for: dependent = 1
else if (dependnets == 1)
withheldAmount = 0.2;
The returned value is calculated as:
[tex]withheldAmount = grossPay * withheldAmount;[/tex]
This gives:
[tex]withheldAmount = 400 * 0.2[/tex]
[tex]withheldAmount = 80.0[/tex]
Hence, the returned value is 80.0

Write the simulate method, which simulates the frog attempting to hop in a straight line to a goal from the frog's starting position of 0 within a maximum number of hops. The method returns true if the frog successfully reached the goal within the maximum number of hops; otherwise, the method returns false. TheFrogSimulationclass provides a method calledhopDistancethat returns an integer representing the distance (positive or negative) to be moved when the frog hops. A positive distance represents a move toward the goal. A negative distance represents a move away from the goal. The returned distance may vary from call to call. Each time the frog hops, its position is adjusted by the value returned by a call to thehopDistance method. g
Answer:
Explanation:
The following code is written in Python. It creates the simulate method which takes in an argument for the max number of hops and the goal distance. Then it loops the number for the max number of hops and asks the user for a hop input using the hopDistance() method (which was not included so it was made, this can be removed if wanted). Then it updates position. If after the max hops goal was reached it returns True, otherwise it returns False.
def simulate(max, goal):
position = 0
print("Goal is " + str(goal))
for x in range(max):
hop = hopDistance()
position += int(hop)
if position >= goal:
return True
else:
return False
def hopDistance():
return input("Frog Hop Distance this hop: ")
print(simulate(4, 20))
Create a class called Dot for storing information about a colored dot that appears on a flat grid. The class Dot will need to store information about its position (an x-coordinate and a y-coordinate, which should both be integers) and its color (which should be a string for now). You can choose what to call your attributes, but be sure to document them properly in the class's docstring.
Don't forget that every function definition, including method definitions, must have a docstring with a purpose statement and signature.
Answer:
Explanation:
The following class is written in Python, it has the three instance variables that were requested. It also contains a constructor that takes in those variables as arguments. Then it has functions to update the positions of the Dot and change its color. The class also has functions to output current position and color.
class Dot:
"""Class Dot"""
x_coordinate = 0
y_coordinate = 0
color = ""
def __init__(self, x_coordinate, y_coordinate, color):
"""Constructor that takes x and y coordinates as integers and a string for color. It ouputs nothing but saves these argument values into the corresponding instance variables."""
self.x_coordinate = x_coordinate
self.y_coordinate = y_coordinate
self.color = color
def moveUp(self, number_of_spaces):
"""Moves the Dot up a specific number of spaces that is passed as a parameter. Updates y_position"""
self.y_coordinate += number_of_spaces
return ""
def moveDown(self, number_of_spaces):
"""Moves the Dot down a specific number of spaces that is passed as a parameter. Updates y_position"""
self.y_coordinate -= number_of_spaces
return ""
def moveLeft(self, number_of_spaces):
"""Moves the Dot left a specific number of spaces that is passed as a parameter. Updates x_position"""
self.x_coordinate -= number_of_spaces
return ""
def moveRight(self, number_of_spaces):
"""Moves the Dot right a specific number of spaces that is passed as a parameter. Updates x_position"""
self.x_coordinate += number_of_spaces
return ""
def dot_position(self):
"""Print Dot Position"""
print("Dot is in position: " + str(self.x_coordinate) + ", " + str(self.y_coordinate))

Because filling a pool/pond with water requires much more water than normal usage, your local city charges a special rate of $0.77 per cubic foot of water to fill a pool/pond. In addition, it charges a one-time fee of $100.00 for filling. This water department has requested you, as a programmer, write a C program that allows the user to enter a pool's length, width, and depth, in feet measurement. The program will then calculate the pool's volume, the volume of water needed to fill the pool with the water level 3 inches below the top, and the final cost of filling the pool, including the one-time fee. And then, all the entered sizes of the pool (in feet) and the three calculated values will be displayed on the screen. Finally, your full name as the programmer who wrote the program must be displayed at the end. To find the volume of the pool in cubic feet, use the formula: volume
Answer:
In C:
#include <stdio.h>
int main(){
float length, width, depth,poolvolume,watervolume,charges;
printf("Length (feet) : "); scanf("%f",&length);
printf("Width (feet) : "); scanf("%f",&width);
printf("Depth (feet) : "); scanf("%f",&depth);
poolvolume = length * width* depth;
watervolume = length * width* (12 * depth - 3)/12;
charges = 100 + 0.77 * watervolume;
printf("Invoice");
printf("\nVolume of the pool: %.2f",poolvolume);
printf("\nAmount of the water needed: %.2f",watervolume);
printf("\nCost: $%.2f",charges);
printf("\nLength: %.2f",length);
printf("\nWidth: %.2f",width);
printf("\nDepth: %.2f",depth);
printf("\nMr. Royal [Replace with your name] ");
return 0;}
Explanation:
This declares the pool dimensions, the pool volume, the water volume and the charges as float
float length, width, depth,poolvolume,watervolume,charges;
This gets input for length
printf("Length (feet) : "); scanf("%f",&length);
This gets input for width
printf("Width (feet) : "); scanf("%f",&width);
This gets input for depth
printf("Depth (feet) : "); scanf("%f",&depth);
This calculates the pool volume
poolvolume = length * width* depth;
This calculates the amount of water needed
watervolume = length * width* (12 * depth - 3)/12;
This calculates the charges
charges = 100 + 0.77 * watervolume;
This prints the heading Invoice
printf("Invoice");
This prints the volume of the pool
printf("\nVolume of the pool: %.2f",poolvolume);
This prints the amount of water needed
printf("\nAmount of the water needed: %.2f",watervolume);
This prints the total charges
printf("\nCost: $%.2f",charges);
This prints the inputted length
printf("\nLength: %.2f",length);
This prints the inputted width
printf("\nWidth: %.2f",width);
This prints the inputted depth
printf("\nDepth: %.2f",depth);
This prints the name of the programmer
printf("\nMr. Royal [Replace with your name] ");
return 0;}

Which describes the third step in visual character development?
Write a program which simulates the result of a person choosing 3 objects in a random order out of a box containing 3 objects in total. The box contains the following 3 objects: apple, ball, cat. A single selection pass of your program describes the random selection of 3 objects out of the box, without replacement. This means that a particular object can only be selected from the box once. At the beginning of a pass, the box is full, so it contains all 3 objects. After an object is selected from the box, your program will print the name of the object and then choose another object without replacing the previous object. The selection process repeats 3 times until the box is empty
Answer:
Explanation:
The following code is written in Python, it loops through a list (box) of the objects and randomly choosing one of the objects. Prints that object out and removes it from the list. Then repeats the process until the box is empty.
import random
box = ['apple', 'ball', 'cat']
print(box)
for x in range(len(box)):
pick = random.randint(0,len(box)-1)
print("Pick " + str(x+1) + ": " + box[pick])
box.remove(box[pick])
print(box)

Explanation:
StreamPal is an audio-streaming application for mobile devices that allows users to listen to streaming music and connect with other users who have similar taste in music. After downloading the application, each user creates a username, personal profile, and contact list of friends who also use the application.
The application uses the device’s GPS unit to track a user’s location. Each time a user listens to a song, the user can give it a rating from 0 to 5 stars. The user can access the following features for each song that the user has rated.
A list of users on the contact list who have given the song the same rating, with links to those users’ profiles
A map showing all other users in the area who have given the song the same rating, with links to those users’ profiles
A basic StreamPal account is free, but it displays advertisements that are based on data collected by the application. For example, if a user listens to a particular artist, the application may display an advertisement for concert tickets the next time the artist comes to the user’s city. Users have the ability to pay a monthly fee for a premium account, which removes advertisements from the application.
Which of the following statements is most likely true about the differences between the basic version and the premium version of StreamPal?
Group of answer choices
a. Users of the basic version of StreamPal use less data storage space on their devices than do users of the premium version of StreamPal.
b. Users of the basic version of StreamPal are more likely to give songs higher ratings than are users of the premium version of StreamPal.
c. Users of the basic version of StreamPal indirectly support StreamPal by allowing themselves to receive advertisements.
d. Users of the basic version of StreamPal spend more on monthly fees than do users of the premium version of StreamPal.
Answer:
Users of the application may have the ability to determine information about the locations of users that are not on their contact list.

Choose a problem that lends to an implementation that uses dynamic programming. Clearly state the problem and then provide high-level pseudocode for the algorithm. Explain why this algorithm can benefit from dynamic programming. Try to choose an algorithm different from any already posted by one of your classmates.
Answer:
Explanation:
The maximum weighted independent collection of vertices in a linear chain graph is a straightforward algorithm whereby dynamic programming comes in handy.
Provided a linear chain graph G = (V, E, W), where V is a collection of vertices, E is a set of edges margins, and W is a weight feature function applied to each verex. Our goal is to find an independent collection of vertices in a linear chain graph with the highest total weight of vertices in that set.
We'll use dynamic programming to do this, with L[k] being the full weighted independent collection of vertices spanning from vertex 1 \to vertex k.
If we add vertex k+1 at vertex k+1, we cannot include vertex k, and thus L[k+1] would either be equivalent to L[k] when vertex k+1 is not being used, or L[k+1] = L[k-1] + W[k+1] when vertex k+1 is included.
[tex]Thus, L[k+1] = max \{ L[k], \ L[k-1] + W[k+1] \}[/tex]
As a result, the dynamic programming algorithm technique can be applied in the following way.
ALGO(V, W, n) // V is a linearly ordered series of n vertices with such a weight feature W
[tex]\text{1. L[0] = 0, L[1] = W[1], L[2] = max{W[1], W[2]} //Base cases} \\ \\ \text{2. For i = 3 to n:- \\} \\ \\\text{3........ if ( L[i-1] > L[i-2] + W[ i ] )} \\ \\ \text{4............Then L[ i ] = L[i-1]} \\ \\ \text{5.........else} \\ \\ \text{6................L[i] = L[i-2] + W[i] }\\ \\ \text{7. Return L[n] //our answer.}[/tex]
As a result, using dynamic programming, we can resolve the problem in O(n) only.
This is an example of a time-saving dynamic programming application.

how can a computer be used by a manager of a shopping mall
Answer:
- used to look at security cameras
- used to buy supplies for the mall (maintenance)
- billing
Answer:
With growing square footage of shopping malls, however, comes the challenge of managing these super structures. Shopping mall managers need to take care of all tenant and building services, including physical security hardware of both the individual tenants’ spaces, the general facility and common areas.
What are some of the security and access control challenges unique to shopping centers and malls?
Multiple tenants across multiple buildings. Access for tenants with their own set of employees needs to be managed efficiently.
Tenant turnover. When a tenant terminates his lease, his ability to access the space should be completely revoked. Mall management must be able to do this in a timely manner for the security of the shared property and for the safety of the next tenant.
Expansion, reduction and relocation of tenants within facilities. While this does not entail revocation of access, mall management must be able to provide smooth transition, in terms of access control to the new space, and denial of access to the previously-occupied space where a new tenant will be moving in.
Security for Shared Entrances and Spaces. Managing access privileges for shared facilities like that in a mall can be challenging. For instance, if a tenant in a mall hires or fires an employee, mall management needs to be informed so they can update access privileges to common entrances and shared spaces. This also applies for maintenance workers, cleaning crews and the like. An efficient access control system allows mall management to control access privileges with ease.

What transport layer protocol does DNS normally use?
Explanation:
DNS uses the User Datagram Protocol (UDP) on port 53 to serve DNS queries. UDP is preferred because it is fast and has low overhead. A DNS query is a single UDP request from the DNS client followed by a single UDP reply from the server.
The transport layer protocol that DNS normally use is the User Datagram Protocol (UDP).
What is transport layer protocol?The Internet Protocol (IP) is a network layer protocol, and the Transmission Control Protocol (TCP) is a transport layer protocol.
A network communication between applications is established and maintained according to the Transmission Control Protocol (TCP) standard. The Internet Protocol (IP), which specifies how computers send data packets to one another, works with TCP.
User Datagram Protocol (UDP) on port 53 is how DNS serves DNS requests. Due to its speed and low overhead, UDP is recommended. A single UDP request from the DNS client and a single UDP response from the server makes up a DNS query.
Therefore, the transport layer protocol used by DNS is User Datagram Protocol (UDP).
