All vectors and subspaces are in Rn. Note you only have 5 attempts for this question. Check the true statements below: - A. If a matrix A is such that AT A then the perpendicular complement of the kernel of A is the image of A. B. For each y and each subspace W, the vector y - projw(y) is orthogonal to W. C. The columns of a matrix A are perpendicular to the rows of AT. D. If y is in a subspace W, then the orthogonal projection of y onto W is y itself. E. If z is orthogonal to u₁ and u₂ and if W=span( u₁, u2), then z must be in W+.
