All margins of a report are _____ inch. * 1 2 3 4

MA_775_DIABLO [31]

Answer:

The answer is "1 inch"

Explanation:

The margin is also known as space, it is the distance between the document 's text and edge. In default, its distance is 1, and it also allows you to customize, the new document, which is set to standard.

In other words, we can say that it implies the one-inch gap between the text and each edge, which is based on your specifications.

It also allows you to customize the margin size of the document, and other choices were wrong because it is the customize size.

You have been asked to write a username validation program for a small website. The website has specific rules on what constitut

umka21 [38]

Answer:

#function to validate username

def valid_username(username):

#checking is length is between 8 to 15

length_valid=True

if(len(username)<8 or len(username)>15):

length_valid=False;

#checking is string is alphanumeric

alphanumeric=username.isalnum()

#checking first_and_last Characters of string is not digit

first_and_last=True

if(username[0].isdigit() or username[len(username)-1].isdigit()):

first_and_last=False

#counting uppercase lowercase and numeric Characters in string

uppercase=0

lowercase=0

numeric=0

for i in username:

if(i.isdigit()):

numeric=numeric+1

elif(i.isalpha()):

if(i.isupper()):

uppercase=uppercase+1

else:

lowercase=lowercase+1

valid_no_char=True

if(uppercase<1 or lowercase<1 or numeric<1):

valid_no_char=False

#printing the result

print("Length of username: "+str(len(username)))

print("All Characters are alpha-numeric: "+str(alphanumeric))

print("First and last Character are not digit: "+str(first_and_last))

print("no of uppercase characters in the username: "+str(uppercase))

print("no of lowercase characters in the username: "+str(lowercase))

print("no of digits in the username: "+str(numeric))

#checking string is Valid or not

if(length_valid and alphanumeric and first_and_last and valid_no_char):

print("Username is Valid\n")

return True

else:

print("username is invalid, please try again\n")

return False

#loop runs until valid_username enterd by user

while(True):

username=input("Enter a username: ")

if(valid_username(username)):

break

Explanation:

The code was created by considering all the required cases asked in the question.

In this program, I asked username from the user continuously until it enters a valid username

first it check for length of string

then check is string contains only alphanumeric characters

then first and last digit is or not

than no of uppercase lowercase and numeric character

using the above parameter declare username valid or not

Taking into account recent technological developments, what technical advances do you think are possible in the next twenty year

Nuclear Fusion reactors may reach the prototype commercial stage , The causes and possible treatment of Alzheimers Disease and Partial cloning of human organs for transplant therapy

Explanation:

Fusion may be an energy technology that seems to be perpetually coming over the horizon, but projects around the world such as SPARC are getting increasingly close to reactors that, although smaller in capacity, can produce net positive power in just a few years. To help accelerate discovery of permanent cure for Alzheimers, an alliance of pharmaceutical companies, nonprofit foundations and government advisers, has developed a partnership to share data from Alzheimer's clinical trials. This would definitely pave way for the permanent cure for Alzheimer. The most common method of therapeutic and reproductive cloning is somatic cell nuclear transfer (SCNT). SCNT involves separating the nucleus from a donor egg, and replacing it with the DNA from the organism meant to be cloned. Scientists could potentially clone organs with SCNT by cloning embryos, extracting the stem cells from the blastocyst, and stimulating the stem cells to differentiate into the desired organ. these three scientific and technological advancements are possible.
