5. Let $B = \{b_1, b_2\}$ and $C = \{c_1, c_2\}$ be bases for $R^2$. Find the change-of-coordinates matrix from $B$ to $C$ and the change-of-coordinates matrix from $C$ to $B$. Clearly show your work. $b_1 = \begin{bmatrix} 7 \\ 5 \end{bmatrix}$, $b_2 = \begin{bmatrix} -3 \\ -1 \end{bmatrix}$, $c_1 = \begin{bmatrix} 1 \\ -5 \end{bmatrix}$, $c_2 = \begin{bmatrix} -2 \\ 2 \end{bmatrix}$

A chemical reaction takes place inside a flask submerged in a water bath, The water bath contains 6.70 kg of water at 37.4 $^\circ$C. During the reaction 106. kJ of heat flows out of the flask and into the bath. Calculate the new temperature of the water bath. You can assume the specific heat capacity of water under these conditions is 4.18 J g$^{-1}$ K$^{-1}$. Round your answer to 3 significant digits.
