Ok, to start off, I am new at this online help. So, please understand if I do something wrong. I got on here because I am an online college student and this week I am getting ready for my final and they gave us tons of problems to get prepared for it. Well, I have this long problem and I don't have a clue how to do it. I would love any help that people could give. I have other questions as well but I will post them all on seperate post. So, here is this problem and if you can help, great and if not, I understand. Thanks in advance!!!
You are a secret agent who has been given these three matrices:
A
[-1 4 -2 0]
[3 3 1 -4]
[0 5 2 -1]
B
[1 2 5]
[-3 4 0]
[2 3 -4]
[-1 2 2]
C
[-2]
[4]
[3]
You are told to go to your drop site over the next four days for further instructions.
1.
a. DAY 1: You are told to multiply the three matrices together in order (A x B x C) to get a fourth matrix D. What is the fourth matrix?
b. DAY 2: You are told to multiply your fourth matrix by the scalar 6 to get a fifth matrix E. What is the fifth matrix?
c. DAY 3: You are told to add the fifth matrix to a matrix whose elements are all "2"s to get a sixth matrix F. What is the sixth matrix?
d. DAY 4: You are told the password for your next assignment is the element f3,1. What is your password?
