Which religious displays were found to NOT violate the Establishment Clause (choose all correct answers)?

Let T be a linear transformation. Define $$T: R^4 \rightarrow R^3$$ by $$T \left(\begin{bmatrix}&1 \\&0\\&0\\&0\end{bmatrix} \right) = \begin{bmatrix}&2\\&3\\&0\end{bmatrix} $$, $$T \left(\begin{bmatrix}&0 \\&1\\&0\\&0\end{bmatrix} \right) = \begin{bmatrix}&0\\&2\\&1\end{bmatrix} $$, $$T \left(\begin{bmatrix}&0 \\&0\\&1\\&0\end{bmatrix} \right) = \begin{bmatrix}&6\\&1\\&2\end{bmatrix} $$, $$T \left(\begin{bmatrix}&0 \\&0\\&0\\&1\end{bmatrix} \right) = \begin{bmatrix}&0\\&3\\&0\end{bmatrix} $$   a) Using the information above, find a formula for $$T(\vec{x})$$ for all $$\vec{x} = \begin{bmatrix}&x_1 \\&x_2\\&x_3\\&x_4\end{bmatrix} $$ in $$R^4$$.   b) Find the standard matrix A of T.   c) Is T one-to-one? Prove your answer using the matrix A.   d) Is T onto? Prove your answer using the matrix A.

Michelangelo’s David statue is 18½ feet tall, including the base. Based on the fact that the density of marble stone is 160 lbs/cubic foot, a person could estimate that the statue weighs about 5,300.0 lbs, or 2,325 kg (1 kg is 1,000 g). Marble has a chemical formula of CaCO3 (calcium carbonate). In the 1750s, Joseph Black found that if calcium carbonate is heated to a temperature of over 825°C, it decomposes and releases “fixed air,” which is CO2, and produces lime (not the citrus fruit but a solid, white chemical compound). The chemical formula of lime is CaO. Write out a balanced equation for the reaction that shows CaCO3 (calcium carbonate) reacting to produce CaO (lime) and CO2 (carbon dioxide).  BYU-Approved David Statue Note: Show all work for this question for full credit.
