Answer:

The NOT operator can be useful to excludes unwanted items (or irrelevant items).

Explanation:

In a lot of computer languages, the "!" symbol stands for the Boolean operator "NOT".

The NOT operator can be useful to excludes unwanted items (or irrelevant items).

Suppose you want to check if two conditions are not equal to each other, and when that condition is true, you can control some specific the outcome, or let something happen...

if ( condition1 != condition2 ) then

whatever you want done....

end if

Look at the color key below the map that shows the overall performance range. What is the range for 1 Year Performance? How does

swat32

A performance range simply means the threshold and maximum percentage of shares that may become earned.

<h3>What is a performance range?</h3>

Your information is incomplete. Therefore, an overview will be given. A performance range is the maximum percentage if shares that may become earned shares due to the attainment of the requirements of the performance.

It should be noted that in this case, the opportunity to incentivize performance will be associated with the relative performance.

Suppose that the tuition for a university is $10,000 this year and increases 4% every year. In one year, the tuition will be $10

Nataliya [291]

Answer:

The programming language is not stated; however, I'll answer using Python programming language (See attachment for proper format)

tuition = 10000

rate = 0.04

for i in range(1,15):

tuition = tuition + tuition * rate

if i <= 10:

print("Year "+str(i)+" tuition:",end=" ")

print(round(tuition,2))

if i == 14:

print("Tuition 4th year after:",end=" ")

print(round(tuition,2))

Explanation:

The first 2 lines initializes tuition and rate to 10000 and 0.04 respectively

tuition = 10000

rate = 0.04

The next line iterates from year 1 to year 14

for i in range(1,15):

This line calculates the tuition for each year

tuition = tuition + tuition * rate

The next 3 lines prints the tuition for year 1 to year 10

if i <= 10:

print("Year "+str(i)+" tuition:",end=" ")

print(round(tuition,2))

The next 3 lines prints the tuition at the 4th year after year 10 (i.e. year 14)

if i == 14:

print("Tuition 4th year after:",end=" ")

print(round(tuition,2))

True or False: Cracking a Vigenère cipher with brute force takes longer than a Caesar cipher, but it is still a reliable method

iragen [17]

Answer:

False

Explanation:

The Vigenere cipher is an encryption method that uses a series of interwoven Ceaser ciphers and a keyword to encrypt text. The difference between this cipher and the Ceaser cipher is the tabular interwoven Ceaser cipher and the keyword.

Multiple keywords can be used in the Vigenere cipher. The use of this keyword makes the brute-force decipher algorithm unreliable for decoding text encrypted with it.
