A 4.5 M NaCl solution freezes at a temperature below zero degrees Celsius \( \left(\mathrm{T}_{\text {Freezing }}<0^{\circ} \mathrm{C}\right) \).

Q22 \( \div-16=\square \) \( 14 p \quad-\frac{p}{8} \quad-\frac{8}{p} \)

Find all the second partial derivatives. \( w_{u u}=\sqrt{u^{7}+v^{9}} \) \( w_{u v}=0 u^{5} \) \( w_{v u}=0 \) \( w_{v v}=72 v^{7} \)

\begin{tabular}{|l|l|}\hline I am thinking of the number 24. \\ What is half of \( 24 ? \)\end{tabular}

\( x ^ { 3 } y ^ { 3 } + 12 x ^ { 4 } y ^ { 2 } + 0 - ( - 5 x ^ { - 6 } y ^ { - 2 } ) ^ { \prime } + ( - 2 x ^ { - 5 } y ^ { - 3 } ) ^ { \prime } + 12 y ^ { 2 } \)

\( f ( x \)
