All vectors and subspaces are in R". Note you only have 5 attempts for this question. Check the true statements below: A. If z is orthogonal to 1 and 2 and if W=span(1, 2), then z must be in W. B. For each y and each subspace W, the vectory - projw(y) is orthogonal to W. C. If y is in a subspace W, then the orthogonal projection of y onto w is y itself. D. If a matrix A is such that AT A then the perpendicular complement of the kernel of A is the image of A. E. The orthogonal projection of y onto a subspace W can sometimes depend on the matrix used to compute. F. If ý = 21 + Z2, where ₁ is in a subspace W and Z2 is in W, then zi must be the orthogonal projection of y onto W. G. The closest vector to y in a subspace W is given by the vector - projw(y). H. The columns of a matrix A are perpendicular to the rows of AT. I. If W is a subspace and if is in both W and W, then must be the zero vector.
