HELP! GIVING AWAY 100 POINTS IF YOU ANSWER! Question #1: Convert the plaintext "PRIME" into ciphertext by using multiplication by 5 in the mod 26 multiplicative cipher system. Provide written evidence of your work/computations.

Question #2: When using a multiplicative cipher system in mod 26, how many different values can be used for the "multiply by" number? Explain/Justify how you arrived at your answer.

Question #3: How does using a prime mod value make a multiplicative cipher system more secure than a non-prime mod? Explain/Justify your answer.

Question #4: The ciphertext "dqw9" was created using a multiplicative key of 4 in mod 37. Convert the ciphertext "dqw9" back into plaintext.

answer: 0,6

step-by-step explanation:

this would make it the y intercept.

the degrees would remain the same ( the number to the left of the decimal point.

the multiply the decimal by 60 to get the minutes and use the numbers to the left of the decimal point.

then multiply the decimal portion of that by 60 for the seconds and round off as needed.

39 .956652

the 39 remains the degrees.

the minutes = 0.956652 x 60 = 57.39912

the minutes = 57

the seconds = 0.39912 x 60 = 23.95 = 24 ( rounded to nearest tenth)

so 39.956652 = 39 degrees, 57 minutes and 24 seconds

-75.159809

the -75 remains the degrees

the minutes = 0.159809 x 60 = 9.58854

the minutes = 9

the seconds = 0.58854 x 60 = 35.31, rounded to nearest tenth = 35.3 seconds

so -75.159809 = -75 degrees, 9 minutes and 35.3 seconds.

the first coordinate is north or south, since it it positive it is north.

the second number is east or west, because it is negative it is west.

39 degrees, 57 minutes and 24 seconds n

-75 degrees, 9 minutes and 35.3 seconds w
