[6] in cryptography we often use matrix operations but modulo some m for the calculations (for example, in hill substitution ciphers.) do the following mod 26 calculations: 2. compute the following matrix product modulo 26 a. [17 22 41 [21 1 18] 1125 22 20 13 17 24 19 2 9 4 6 b. a "key matrix" is use to encode a message where blocks of letters are replaced by blocks of numbers (for example, bad might become 204.) to decrypt the message, it is necessary to invert the key matrix (mod 26). if the key matrix is given as, [10 18 a = |17 1 1 7 21 4 then compute a-1 mod 26. (hint: row reduce the augmented matrix using modulo 26 calculations. recall that the modulus of a number n is the reminder after dividing by the modulus m. for example, 55 is equal to (we say "congruent to") 3 modulus (or "mod 26") since 55 = 2(26) 3.) you may use software to assist doing this.

it can be to see completed examples before writing, in order to examine what makes for an effective piece. see how these intros give some context before posing the topic and lead naturally into the body paragraphs, where the evidence will be listed. you can imagine how the author has organized the rest of the piece.

"we buried my cousin last summer. he was 32 when he hanged himself from a closet coat rack in the throes of alcoholism, the fourth of my blood relatives to die prematurely from this deadly disease. if america issued drinking licenses, those four men—including my father, who died at 54 of liver failure—might be alive today. that is a good example piece   some steps that are .

. writing something that happened to you

.read a book you like to get ideas from there

. lastly you can make a venn diagram

hope this plz make brainliest
