Answer:
magine a coordinate plane. Let’s say we want to draw an angle that’s 144° on our plane. We start on the right side of the x-axis, where three o’clock is on a clock. We rotate counterclockwise, which starts by moving up. We keep going past the 90° point (the top part of the y-axis) until we get to 144°. We draw a ray from the origin, which is the center of the plane, to that point. Now we have a ray that we call the terminal side. But we need to draw one more ray to make an angle. We have a choice at this point. Our second ray needs to be on the x-axis. If we draw it from the origin to the right side, we’ll have drawn an angle that measures 144°. If we draw it to the left, we’ll have drawn an angle that measures 36°. This second angle is the reference angle. It’s always the smaller of the two angles, will always be less than or equal to 90°, and it will always be positive. Here’s an animation that shows a reference angle for four different angles, each of which is in a different quadrant. Notice how the second ray is always on the x-axis.

Suppose a program is supposed to reverse an array. For example, if we have the array arr = {1, 2, 3, 4, 5}, after reversing the array we would have arr = {5, 4, 3, 2, 1}.
Most of the code for the program is shown here:
Const int SIZE = 5;
int arr[SIZE] = {1, 2, 3, 4, 5};
int firstindex =0, lastindex = SIZE-1, temp;
1 _______________________________
{
temp = arr[firstindex];
arr[firstindex] = arr[lastindex];
arr[lastindex] = temp;
firstindex++;
lastindex--;
}
All of the following options below could be correctly inserted at line 1 in the code shown above EXCEPT:
a. while(firstindex < lastindex)
b. while(firstindex <= lastindex)
c. for(int i=0; i<(SIZE/2-1); i++)
d. for(int i=0; i<(SIZE/2); i++)
Answer:
The answer is "Choice C".
Explanation:
In this question, the choice C is correct because all the other options will the output "5 4 3 2 1" and it will given "5 2 3 4 1" as output which is defined in the attached file. please find it.
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;}

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.

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))

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).

Which one is the result of the output given by a computer?
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])

lst.remove(x)
return ist Restore original file
Answer:
Explanation:
The code provided aside from some minor errors (fixed version down below) is correct, but it will never be able to accomplish what is being asked in the question. This is because this code is simply copying and returning the exact same list that is passed as an argument, because it is looping through it and comparing its own elements. In order to accomplish what is asked in the question, two lists need to be passed as parameters. The first would be the original list, and the second would be a list of test elements that will be used to compare and see if they exist in the original list. This would allow us to create a new list with only the elements that existed in the original 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.
