Determine whether the following statement is true or false, where all the vectors and subspaces are in R". Justify the answer. If A = QR, where Q has orthonormal columns, then R= Q'A. Choose the correct answer below. O A. The statement is true. Since Q has orthonormal columns, QTQ=I. so QTA=Q"(QR) = IR = R. O B. The statement is false. Since Q has orthonormal columns, Q'Q= 0. So QTA=Q"(QR) = 0. O C. The statement is true. Since Q has orthonormal columns, QTQ= 1. So QTA= QT(QR) = 1R=R. O D. The statement is false. If Q is square, then Q' =Q and R=QA. However, if Q is not square, the matrix - 1 does not exist and this statement is false.

Transcribed Image Text:Determine whether the following statement is true or false, where all the vectors and subspaces are in R". Justify the answer.
If A = QR, where Q has orthonormal columns, then R= Q'A.
Choose the correct answer below.
O A. The statement is true. Since Q has orthonormal columns, QTQ=I. so QTA=Q"(QR) = IR = R.
O B. The statement is false. Since Q has orthonormal columns, Q'Q= 0. So QTA=Q"(QR) = 0.
O C. The statement is true. Since Q has orthonormal columns, QTQ= 1. So QTA= QT(QR) = 1R=R.
O D. The statement is false. If Q is square, then Q' =Q and R=QA. However, if Q is not square, the matrix
- 1
does not exist and this
statement is false.
