(1 point) Let B be the basis of R2 consisting of the vectors {[:] [3]} and let C be the basis consisting of -3 2 Find a matrix P such that ſõlc = P[7] for all i in R? 1/2 7/16 P= -1/2 55/16 a. Write the vector (3,12, 11) as a linear combination of a = (-1,4, -2). az = (0,4,5) and a3 =(-4, 4, 2). Express your answer in terms of the named vectors. Your answer should be in the form 4a1 +52 + 6ās, which would be entered as 4a1 + 5a2 + 6a3. (3, 12, 11) = b. Represent the vector (3, 12, 11) in terms of the ordered basis B={(-1,4,-2),(0,4,5),(-4.4.2)} . Your answer should be a vector of the general form <1,2,3). [(3, 12, 11)]B
