y'+2y = 5-e^(-4x), y(0)=-11
Use Euler's Method with a step size of h = 0.1 to find approximate values of the solution as x= 0.1, 0.2, 0.3, 0.4, and 0.5. Compare them to the exact values of the solution at these points.
Answer:
see attached
Explanation:
A differential equation solver says the exact solution is ...
y = 5/2 -14e^(-2x) +1/2e^(-4x)
The y-values computed by Euler's method will be ...
y = ∆x·y' = 0.1(5 - e^(-4x) -2y)
The attached table performs these computations and compares the result. The "difference" is the approximate value minus the exact value. (When the step size is decreased by a factor of 10, the difference over the same interval is decreased by about that same factor.)

Antivirus software, or Anti-virus software (also known as AV software), otherwise called anti malware, is a PC program used to forestall, distinguish, and eliminate malware.
Antivirus software was initially evolved to identify and eliminate PC infections, thus the name. Be that as it may, with the expansion of different sorts of malware, antivirus software began to give security from other PC dangers. Specifically, current antivirus software can shield clients from: noxious program criminals.
A few items additionally incorporate security from other PC dangers, for example, tainted and noxious URLs, spam, trick and phishing assaults, online identity (privacy), web based financial assaults, social engineering techniques, advanced persistent threat (APT).

After reading through the code, what will happen when you click run?
Answer:
B.) Laurel will try to collect treasure when there is not any and it causes an error
Explanation:
Laurel is at the top right corner of the map. When you click run, laurel moves 1 step ahead. This spot is right above the coordinate of the very first diamond. There is no treasure at this spot.
Therefore, when the next command calls for collecting, there will be an error, as there is no treasure at the spot right above the first diamond.

Write a java program to read an array of positive numbers. The program should find the difference between the alternate numbers in the array and find the index position of the smallest element with largest difference. If more than one pair has the same largest difference consider the first occurrence.
Answer:
int s;
int[] num= new int[s];
Scanner sc = new Scanner(System.in);
System.out.printIn("Enter array size");
size = sc.nextInt();
for (i = 0; i < s; i++){
num[i] = sc.nextInt();
}
int[] difference;
int count = 0;
for (i = 0; i < num.length(); i= i + 2){
if (num[i] > num[i+1]){
difference[count] = num[i] -num[i+1];
}else{
difference = num[i+1] - num[i];
}
}
int max = 0;
for (int i : difference) {
if ( i > max){
max = i;
}
}
int result = Arrays.stream(difference).boxed().collect(Collectors.toList().indexOf(max);
System.out.printIn(result);
Explanation:
The Java source code uses procedural method to execute a task. The program prompts for user inputs for the array size and the items in the array. Assuming the array has an even length, the adjacent items of the array are subtracted and stored in another array called difference. The index of the maximum value of the difference array is printed on screen.

Write a program that declares a two-dimensional array named myFancyArray of the type double. Initialize the array to the following values: 23 14.12 17 85.99 6.06 13 1100 0 36.36 90.09 3.145 5.4 1. Create a function that will return the sum of all elements in the array. Call this function from main and print out the result. 2. Create a function that will use a nested loop to display all the elements in the array to the screen. Call this function from main.
Answer:
This solution is provided in C++
#include <iostream>
using namespace std;
double sumFancyArray(double myarr[][6]){
double sum = 0.0;
for(int i = 0;i<2;i++) {
for(int j = 0;j<6;j++){
sum+=myarr[i][j];
}}
return sum;
}
void printFancyArray(double myarr[][6]){
for(int i = 0;i<2;i++) {
for(int j = 0;j<6;j++){
cout<<myarr[i][j]<<" ";
}
}
}
int main(){
double myFancyArray[2][6] = {23, 14.12, 17,85.99, 6.06, 13, 1100, 0, 36.36, 90.09, 3.145, 5.4};
cout<<sumFancyArray(myFancyArray)<<endl;
printFancyArray(myFancyArray);
return 0;
}
Explanation:
This function returns the sum of the array elements
double sumFancyArray(double myarr[][6]){
This initializes sum to 0
double sum = 0.0;
This iterates through the row of the array
for(int i = 0;i<2;i++) {
This iterates through the column
for(int j = 0;j<6;j++){
This adds each element
sum+=myarr[i][j];
}}
This returns the sum
return sum;
}
This method prints array elements
void printFancyArray(double myarr[][6]){
This iterates through the row of the array
for(int i = 0;i<2;i++) {
This iterates through the column
for(int j = 0;j<6;j++){
This prints each array element
cout<<myarr[i][j]<<" ";
}
}
}
The main starts here
int main(){
This declares and initializes the array
double myFancyArray[2][6] = {23, 14.12, 17,85.99, 6.06, 13, 1100, 0, 36.36, 90.09, 3.145, 5.4};
This calls the function that returns the sum
cout<<sumFancyArray(myFancyArray)<<endl;
This calls the function that prints the array elements
printFancyArray(myFancyArray);
return 0;
}

what command in cisco IOS allows the user to see the routing table
Answer:
Show IP route command
Explanation:
(20 points). Some matrixes have very special patterns, for example, in the following matrix, the numbers in the first row are equal to the number of their respective column; the numbers in the first column are equal to the square of the number of their respective row; when the row number equals to the column number, the elements are equal to 1; the rest elements are the sum of the element just above them and the one to their left. Write a user-defined function program in the program, you need to use while loops), and then use the function you write to create the following matrix (show the command you use). 1 4 9 16 2 1 10 26 3 4 1 27 4 5 8 13 9 22 1 23
Answer:
#include <iostream>
using namespace std;
void matrix(){
int row = 5, col = 6;
int myarr[row][col];
for (int i = 0; i < 5; i++){
for (int x = 0; x < 6; x++){
if (i == 0){
myarr[i][x] = (x+1)*(x+1);
}else if ( x == 0){
myarr[i][x] = (i+1)*(i+1)*(i+1);
} else if ( i == x){
myarr[i][x] = (i+1);
} else{
myarr[i][x] = myarr[i-1][x] + myarr[i][x-1];
}
}
}
for (int i = 0; i < 5; i++){
for (int x = 0; x < 6; x++){
cout<< myarr[i][x] << " ";
}
cout<< "\n";
}
}
int main(){
matrix();

A hacker posing as a potential customer has connected to your network and has discovered that a server running Windows Server has a configuration that a misconfiguration on a Windows Server that exposes the PowerShell prompt. The hacker executes a script to log valuable information about the server. Which vulnerabilities did the hacker exploit
Answer:
Lack of ips
Insecure configuration
Explanation:
Lack of IPS
This is fully known as intrusion prevention softwares this works by enabling the firewall and protecting the computer system from unauthorised users and potential attackers and it prevents data from being stolen by identifying potential attacks. It monitors the network continuously, thereby looking for possible malicious threats and also capturing informations about these threats.
Insecure configuration
Obviously if you have power shell enabled then you would have a secure configuration. Attackers can easily access your system in the presence of this flaw.
Write a C++ program that tests whether the array has four consecutive numbers with the same values. bool isConsecutive(int values[], int size) In the main() program you should prompt the user to enter a series of integers and display if the series contains four consecutive numbers with the same value. Your program should first prompt the user for the number of integers in the list or number of values in the series. Assume the maximum array size is 20. No global variables may be used Use a function prototype for said function The function can not do any cin or cout The main() function will do all the cin and cout You may assume the list contains positive integers only Sample runs (bolded text is output) : Enter the number of values: 6 Enter a value: 3 Enter a value: 4 Enter a value: 5 Enter a value: 5 Enter a value: 5 Enter a value: 5 The list has consecutive four numbers! Enter the number of values: 9 Enter a value: 3 Enter a value: 4 Enter a value: 5 Enter a value: 50 Enter a value: 5 Enter a value: 6 Enter a value: 5 Enter a value: 5 Enter a value: 6 The list has no consecutive fours numbers!

Suppose that we want to enhance the processor used for Web serving. The new processor is 10 times faster on computation in the Web serving application than the original processor. Assuming that the original processor is busy with computation 40% of the time and is waiting for I/O 60% of the time, what is the overall speedup gained by incorporating the enhancement
Answer:
The overall speedup gained by incorporating the enhancement is 1.563
Explanation:
Using Amdahl's Law;
The overall speedup [tex](N) =\dfrac{1}{(1-P) + ( \dfrac{P}{n})}[/tex]
where;
P = Fraction Enhanced for Old Processor
n = speedup enhancement as a result of the new processor
P = 40% = 0.40 and n = 10
∴
The overall speedup (N) is:
[tex]=\dfrac{1}{(1-0.4) + ( \dfrac{0.4}{10})}[/tex]
[tex]=\dfrac{1}{(0.6) + ( 0.04)}[/tex]
[tex]=\dfrac{1}{0.64}[/tex]
= 1.563
Thus, the overall speedup gained by incorporating the enhancement is 1.563
