Question

Yvette encoded a secret phrase using matrix multiplication. Using A = 1, B = 2, C = 3, and so on, she multiplied the clear text to code for each letter by the matrix to get a matrix that represents the encoded text. The matrix representing the encoded text is given. What is the secret phrase? Determine the location of spaces after you decode the text.

a) FIND THE PRODUCT
b) FIND THE INVERSE
c) FINE IS THE PIANO
d) FINE IS A WARM DAY

Answer 1

The question asks for the decoding of a secret phrase from an encoded matrix; however, the necessary numerical data is missing to carry out the required matrix operations.

Step-by-step explanation:

The student's question pertains to decoding a secret phrase from an encoded text using matrix operations. Unfortunately, the essential numerical data for the matrix encoding the secret phrase is missing, thus making it impossible to answer the specific question directly. To decode the secret phrase, one would typically require both the encoded matrix and the encoding matrix used. If these matrices were provided, the process would involve matrix multiplication to convert the clear text into encoded form or finding the inverse of the encoding matrix to revert the encoded text back to the clear text. Spaces would need to be determined by context once the characters are decoded, as matrix operations do not directly reveal them.
