Recall that in order to start the scavenger hunt, Darnell needs to send an encoded message to Raya.a) Based on the table, what is the number string that corresponds to the text “Hello Raya”? (1 point) b) How many 2 x 1 matrices will be in the sequence? How do you know that? (2 points) c) Write the sequence of 2 x 1 matrices that Darnell will use to encode. (1 point) d) What is the enumerated matrix B? (2 points) e) What is A × B? (Show your work) (4 points) Part 2: Use a decoding matrix.Raya sent an encoded message back to Darnell that provides the location of the next clue.To decode the message, Darnell will need to use the inverse of the 2 x 2 encoding matrix, A. Complete the following problems to determine the next clue.a) What is the determinant of A? Show your work or explain. (3 points) b) What is the inverse matrix of A? Show how to get A–1. (4 points) c) What is A–1 × C? (4 points) d) Describe how to use the resultant matrix from part c to decode the message. What does the decoded message say? (4 points)
