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.
Answers
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.)

why ROM is called non volatila Memory?
Answers
Answer:
Explanation:
ROMs that are read only memory are called non volatile because all of the data that are inside it happens to not get erased after shutting down the system or computer and starting it all over again. The opposite is this phenomenon is RAM. In RAM, they are being called volatile because all of the data that are inside it happens to get erased once shutting down of the system or computer occurs and it is being restarted.
This is telling us that ROM irrespective, stores data while it is on and also while it is off, it doesn't matter. It never forgets data, unless of course, in a situation whereby it is erased.
Volatile memory stores data as long as it is powered. ROM, which stands for read-only memory, is called non-volatile memory because of they do not lose memory when power is removed. Data stored in ROM cannot be electronically modified after the manufacture of the memory device.

Write a program that can be used to calculate the federal tax. The tax is calculated as follows: For single people, the standard exemption is $4,000; for married people, the standard exemption is $7,000. A person can also put up to 6% of his or her gross income in a pension plan. The tax rates are as follows: If the taxable income is:
Between $0 and $15,000, the tax rate is 15%.
Between $15,001 and $40,000, the tax is $2,250 plus 25% of the taxable income over $15,000.
Over $40,000, the tax is $8,460 plus 35% of the taxable income over $40,000. Prompt the user to enter the following information:
Marital status
If the marital status is “married,” ask for the number of children under the age of 14
Gross salary (If the marital status is “married” and both spouses have income, enter the combined salary.)
Percentage of gross income contributed to a pension fund Your program must consist of at least the following functions:
Function getData: This function asks the user to enter the relevant data.
Function taxAmount: This function computes and returns the tax owed.
To calculate the taxable income, subtract the sum of the standard exemption, the amount contributed to a pension plan, and the personal exemption, which is $1,500 per person. (Note that if a married couple has two children under the age of 14, then the personal exemption is $1,500 ∗ 4 = $6,000.)
Since your program handles currency, make sure to use a data type that can store decimals with a decimal precision of 2.

Lastly, How do u get a Virus Protection.
Answers
Question: How can you reboot a laptop?
Answer: Rebooting a computer simply means to restart it. If you're using Microsoft Windows, you can click the "Start Menu," click the "Power" button and click "Restart" in the submenu to restart your computer. If you still have problems with the computer, you can also choose the "Shut Down" option in the "Power" submenu to turn the computer off altogether, let it sit for a bit and then turn it back on.
Question: How do you get an upgrade for a tower?
Answer: You can upgrade your existing Tower installation to the latest version easily. Tower looks for existing configuration files and recognizes when an upgrade should be performed instead of an installation. As with installation, the upgrade process requires that the Tower server be able to access the Internet. The upgrade process takes roughly the same amount of time as a Tower installation, plus any time needed for data migration. This upgrade procedure assumes that you have a working installation of Ansible and Tower.
Question: How do you get a Virus Protection?
Answer: Use an antimalware app - Installing an antimalware app and keeping it up to date can help defend your PC against viruses and other malware (malicious software). Antimalware apps scan for viruses, spyware, and other malware trying to get into your email, operating system, or files.

Write a function max_magnitude() with two integer input parameters that returns the largest magnitude value. Use the function in a program that takes two integer inputs, and outputs the largest magnitude value. Ex: If the inputs are: 5 7 the function returns: 7 Ex: If the inputs are: -8 -2 the function returns: -8 Note: The function does not just return the largest value, which for -8 -2 would be -2. Though not necessary, you may use the built-in absolute value function to determine the max magnitude, but you must still output the input number (Ex: Output -8, not 8). Your program must define and call the following function:
Answers
Answer:
The question is answered in python
def max_magnitude(a,b):
if abs(a) > abs(b):
return a
else:
return b
num1 = int(input("Num 1: "))
num2 = int(input("Num 2: "))
print(max_magnitude(num1,num2))
Explanation:
This question is answered using the concept of absolute value to get the integer with the highest magnitude
First, the function is defined with integer parameters a and b
def max_magnitude(a,b):
This checks if a has the highest magnitude
if abs(a) > abs(b):
If true, it returns a
return a
If otherwise, it returns b
else:
return b
The main starts here
The next two lines prompt the user for inputs
num1 = int(input("Num 1: "))
num2 = int(input("Num 2: "))
This calls the function
print(max_magnitude(num1,num2))

If you have a line that is 2.5 inches in decimal, what is that in fraction form?
2 5/16 inches
2 1/4 inches
2 3/4 inches
2 1/2 inches
If you are asked to measure 9/16th on a ruler how many lines would you have to count?
Answers
Answer: 2 1/2 inches; 9 lines
Explanation:
If one has a line that is 2.5 inches in decimal, this in fraction form will be written as:
= 2.5 inches = 2 5/10 inches.
When we reduce 5/10 to its lowest term, this will be 1/2. Therefore 2.5 inches = 2 1/2 inches.
Since each mark on a ruler is 1/16, therefore 9/16 will be (9/16 ÷ 1/16) = (9/16 × 16/1) = 9 lines

Write a program that prompts the user to input a string and outputs the string in uppercase letters. (Use a character array to store the string.)
Answers
Answer:
Explanation:
The following code is written in Java. It asks the user for a string/sentence and then grabs every character in the string, capitalizes it, and saves it in a char ArrayList. Then it concatenates the char array into a String variable called output and prints the capitalized String.
public static void capitalizeMe() {
Scanner in = new Scanner(System.in);
System.out.println("Enter a String:");
String inputSentence = in.nextLine();
ArrayList<Character> capitalString = new ArrayList<Character>();
for (int x = 0; x < inputSentence.length(); x++) {
capitalString.add(Character.toUpperCase(inputSentence.charAt(x)));
}
String output = "";
for (char x: capitalString) {
output += x;
}
System.out.println(output);

In the program below, which variable has the same scope as strA?

def passwordMaker (strA, numC):
if len(strA) > 4:
answer = dogName[0:3]
return answer + str(numC)
else:
return 'xk&' + str(numC)
Answers
Answer:
" numC " is the correct answer
Explanation:
The reason is that on line 3 of code it has "def passwordMaker (strA, numC):"
strA and numC are both in "( )" which is the scope and only things inside are varibles. Also its the only line that has strA in it.
The scope of a variable is the extent at which the variable can be referenced.
The variable with the same scope as strA is variable numC
From the program, we have the following function definition
def passwordMaker (strA, numC):
Variables strA and numC are declared along with the function passwordMaker
This means that:
Variables strA and numC have the same scope
Hence, the variable with the same scope as strA is variable numC
