On each sheet, put your name, your section leader"s name and your section meeting time. No proof is needed for true-false questions; just write clearly. You may assume given matrix expressions are well de ned (i. e. the matrix sizes are compatible): (a) below are a matrix a and the matrix rref(a) produced by matlab. 1 and d = {x r2 : p(x1 )2 + (x2 17)2 3} . Compute the area of the set e = {ax : x is in d}. (b) (5 points) suppose a and b are 5 5 matrices with det(a) = 10 and det(b) = 4 . Compute the determunant of the matrix m = 2 a3b 1 : (a) (14 points) let p1 denote the vector space of polynomials of degree at most 1; then.
