Assume that T is a linear transformation. Find the standard matrix of T.

$T:{R}^{2}\Rightarrow {R}^{2}$ first reflects points through the vertical ${x}_{2}-a\xi s$ and then reflects points through the line $X}_{2}={X}_{1$ .

$A=?$

Hi I need help with thisquestion.
A uniform metal rod, with a mass of 3.1 kg and a length of 1.2 m,is attached to a wall by a hinge at the base. A horizontalwire bolted to the wall 0.51 m above the base of the rod holds therod at an angle of 25 degrees above the horizontal. The wireis attached to the top of the rod. (a) Find the tension inthe wire. (b) Find the horizontal and verticalcomponents of the force exerted on the rod by the hinge.
Thank you

Consider the following data and corresponding weights.
$$\begin{array}{|cc|}\hline {x}_{i}& Weight(Wi)\\ 3.2& 6\\ 2.0& 3\\ 2.5& 2\\ 5.0& 8\\ \hline\end{array}$$
Compute the weighted mean. b. Compute the sample mean of the four data values without weighting. Note the dif-ference in the results provided by the two computations.

Sulfuric acid dissolves aluminum metal according to the reaction:

$2Al\left(s\right)+3{H}_{2}S{O}_{4}\left(aq\right)\Rightarrow A{l}_{2}{\left(S{O}_{4}\right)}_{3}\left(aq\right)+3{H}_{2}\left(g\right)$

Suppose you want to dissolve an aluminum block with a mass of 15.2 g.

What minimum mass of$H}_{2}S{O}_{4$ (in g) do you need? What mass of $H}_{2$ gas (in g) does the complete reaction of the aluminum block produce?
