(c) An object with an initial temp of To is of water, the temperature of tank of in wept at \( 15^{\circ} \mathrm{C} \). After 25 min which is kept is the temperature of the object is \( 178^{\circ} \mathrm{C} \), and after 50 minutes \( 89^{\circ} \mathrm{C} \). it is (i) Presuming that Nenton's law of cooling applies, what is the initial value of \( T_{0} \) ?

6 powered by \( 2(n+1) \) minus 2 powered by \( n+3 \) multiplied by 3 powered by \( n+ \) 2 plus 36 can be divided by 900 and \( n \) is natural number

\( \left. \begin{array} { l l } { 3.1 } & { \frac { 1 } { 4 } - 25 x ^ { 6 } } \\ { 3.2 } & { 125 ( x - y ) ^ { 3 } - 27 \vee v } \\ { 3.3 } & { x ^ { 5 } + x ^ { 4 } - x - 1 } \\ { 3.4 } & { x ^ { 2 } ( b - 1 ) + 5 x ( 1 - b ) + 6 b - 6 } \\ { 3.5 } & { 6 a b - 9 a ^ { 2 } - b ^ { 2 } + 25 c ^ { 2 } } \end{array} \right. \)

Order from least to greatest. \[ \frac{3}{5} \quad \frac{5}{9} \quad \frac{1}{3} \]
