Write a procedure

input:a polygon and a linear transformation

output :applying the transformation to the polygon

Find the coordinates of the linear transformation that would have  the a larger square to the pink (smaller) square.Apply the transformation to the blue square.

please help with this, thnaks

Use a procedure that takes as input a positive integer and two real numbers a and b
and produces as output  a polygon centered at (a, b). Base on the procedure,  obtain a list of twenty decagons centered in (0, 0), (1, 1), ..(20, 20)

(I have no hint,please help, thanks)

 A RSA with the modulus n = 119 and the exponent e = 7, with the 95-character
alphabet consisting of the printable ASCII characters to encrypt the word “Yes”.
so that Y=58, e=70, s=84. Give your encryption as a list of three numbers.

Then use the same set (that is the modulus n = 119 and the exponent e = 7) to decrypy the list of number  [42,59,4,59,27,59]

Here is my code, what's wrong with it. Please help. Thanks

The question is“fsqFsHn sGGousG” is the result of applying a Caesar cipher to its original title. A 53-character alphabet
consisting of all the upper-case letters, a space, and all the lower-case letters
was used; consequently the space in the middle might or might not correspond to a
space in the title. Determine what the original title was.

this is what I wrote: (please help me correct it, thank you)

>Alphabet:="ABCDEFGHIJKLMNOPQRSTUVWXYZ abcdefghijklmnopqrstuvwxyz";

The string below was encrypted using an affine cipher on the 27 letter alphabet
“ abcdefghijklmnopqrstuvwxyz” (there is a space in the 0th position.) Decrypt it.
