Back up and placing the back up away from earthquake location

Further Explanation:

Data protection is the main concern of all the computer users around the world. The data can be either damaged by the software programs developed by invaders or physical disasters. Physical disasters are inevitable. So in case of earthquake, following options can be considered to protect the data int he computer:

1. Taking a back up of data and placing the device containing back up at another location.

2. Upload a copy of the data onto the cloud so that it can be restored later.

Note: Both these are the precautionary actions just to reduce the risk of data loss during earthquake. There is no defined way to protect the data in computer while there is an earthquake in progress.

if( foo < 0.0 ):
    print( "negative" )
elif( foo > 0.0 ):
    print( "positive" )
else

Namespaces cannot have namespaces as members.<br><br> True<br><br> False

Anna71 [15]

Answer:

False

Explanation:

namespaces can be nested. That is we can have a hierarchy of namespaces.

For examples suppose we have a namespace top. Within this we have another namespace first. At the next level we have a namespace called second. Then we have a class MyClass as a member of this namespace second. Then the complete description of the class will be as follows:

top::first::second::MyClass

[20 pts] Write the function rectangle(perimeter, area), which takes two positive integers, perimeter and area. It returns an int

MrRissso [65]

Hi, you haven't provided the programing language in which you need the code, I'll explain how to do it using Python, and you can follow the same logic to make a program in the programing language that you need.

Answer:

import math

def rectangle(perimeter, area):

l1_1 = (perimeter+math.sqrt((perimeter**2)-(16*area)))/4

l1_2 = (perimeter-math.sqrt((perimeter**2)-(16*area)))/4

l2_1 = area/l1_1

l2_2 = area/l1_2

print(l1_1,l2_1)

print(l1_2,l2_2)

if l1_1.is_integer() and l2_1.is_integer() and l1_1>0 and l2_1>0:

return(int(max(l1_1,l2_1)))

elif l1_2.is_integer() and l2_2.is_integer() and l1_2>0 and l2_2>0:

return(int(max(l1_2,l2_2)))

else:

return(None)

Explanation:

We import math to make basic operations
We define the rectangle function that receives perimeter and area
We calculate one of the sides (l1_1) of the rectangle using the quadratic equation to solve 2h^2 - ph + 2a = 0
We calculate the second root of the quadratic equation for the same side (l1_2)
We calculate the second side of the rectangle using the first root on w = a/h
We calculate the second side of the rectangle using the second root on w= a/h
We verify that each component of the first result (l1_1, l2_1) is an integer (using the build-in method .is_integer) and greater than 0, if True we return the maximum value between them (using the max function) as w
If the first pair of sides evaluate to False we check the second root of the equation and if they meet the specification we return the max value
if all the if statements evaluate to false we return None to indicate that not positive or integer sides were found
