Exercise: We saw earlier how to construct the 2×2 matrices that rotate a vector, that reflect a vector across the 45° line y=x, or that project onto the x- or y-axes. The goal of this problem is to construct the matrix that projects a vector onto the line that makes an angle of θ with the x-axis. (We're implicitly using the fact that the function

Raj encoded a secret phrase using matrix multiplication. using a = 1, b = 2, c = 3, and so on, he multiplied the clear text code for each letter by the matrix to get a matrix that represents the encoded text. the matrix representing the encoded text is . what is the secret phrase? determine the location of spaces after you decode the text. yummy is the corn the tomato is red the corn is yummy red is the tomato
