Hi!
The mouse and the keyboard are <em>input devices. </em>By using them, we can input data which will give us a (hopefully) desired output!
For example...
Just by using my keyboard to type, I'm inputting data in the form of ASCII characters and symbols.
By using my mouse to click on an area so I can move this sentence on a new line, I had to input a request to do such!
Hopefully, this helps! =)
Answer:
(a) Correlated.
Explanation:
Correlated subquery :These sub queries reference columns from outer table or uses values from outer query.These sub queries are processed atleast once for every row processed.So because of this reason correlated sub queries can be slow.Since the query in the question also uses value from the outer query so it is a correlated query.
I have a very good example of the program you need written on Python. You can use this (sorry for bad tabulation):
import math
import math
def main():
function = input("Enter a function f(x):\n")
x = 0
y = 0
for rows in range(10,-11,-1):
for col in range(-10,11,1):
x=col
roundfx = round(eval(function))
if roundfx == rows:
print("o", end="")
if rows==0 and col==0 and not rows == roundfx:
print("+", end="")
if col == 0 and not rows == 0 and not rows == roundfx:
print("|", end="")
if rows==0 and not col==0 and not rows == roundfx:
print("-", end="")
else:
if not rows == 0:
if not col == 0:
if not rows == roundfx:
print(" ", end="")
print()
main()
Answer:
belongs to everyone.
Explanation:
A National Archive can be defined as the collection of data (informations) and documents by the government of a particular country for record keeping purposes.
Basically, these documents comprises of information about important and historical events that have happened in the country or events generally related with the country.
Hence, the National Archives is part of the federal government, which means that its content belongs to everyone. This is simply because the federal government is a government of the people, for the people and by the people. Thus, the ownership of governmental institutions or agencies belongs to the general public i.e the citizens of the country.
