Y'+2y = 5-e^(-4x), y(0)=-11

Computers and Technology
1 answer:
Anastaziya [24]3 years ago
4 0

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.)

Identify way in which computer are used in personnel management
Lyrx [107]

The main roles of computer in human resource management are decreasing time complexity, flexibility, record keeping problem etc. HRM system process lots of data everyday with the help of computer. This data processed easily without any fear of data loss so computer a vital role in human resource management system. The usage of computer in human resource management can be usually referred to as management information system. It can also be called as human resource information system. Usually what a computer does, it converts all the data or we can say raw data into meaningful and usable information required by the manager to take decisions, and for planning and control.

expeople1 [14]
The answer is SSID

SSID which in full stands for Service Set Identifier is used to identify a network. It ensures that clients are able to locate a WLAN in which they are attached to. In Layman’s terms, it’s the username or the primary name in a WiFi setup in which a user joins and is connected to.

The Fibonacci sequence starts 1, 1, 2, 3, 5, 8, .. . . Each number in the se-quence (after the first two) is the sum of the prev
dem82 [27]

Answer:

value=int(input("Enter the number up-to the user wants the Fibonacci series: "))

a=0

b=1

c=1

for x in range(value):

   print(c,end=" ")

   c=a+b

   a=b

   b=c

Output :

  • If the user input 5, then the output is "1 1 2 3 5".
  • If the user input 10, then the output is "1 1 2 3 5 8 13 21 34 55".

Explanation:

  • The above defined a python program which is used for the Fibonacci series.
  • The first line of the program is used to instruct the user and take the input from the user.
  • Then the for loop executes up-to that range value.
  • Then in the for-loop, the two variable needs to store the current value and previous value which is used to give the series after addition.
