QuestionA bottle of ginger ale initially has a temperature of 72F72^{\circ} \mathrm{F}. It is left to cool in a refrigerator that has a temperature of 34F34^{\circ} \mathrm{F}. After 10 minutes the temperature of the ginger ale is 62F62^{\circ} \mathrm{F}. Complete parts a through c. a. Use Newton's Law of Cooling, T=C+(T0C)ekt\mathrm{T}=\mathrm{C}+\left(\mathrm{T}_{0}-\mathrm{C}\right) e^{k t}, to find a model for the temperature of the ginger ale, T , after t minutes. T=34+(38)e0.0305tT=34+(38) e^{-0.0305 t} (Simplify your answer. Use integers or decimals for any numbers in the equation. Round to four decimal places as needed) b. What is the temperature of the ginger ale after 15 minutes? F\square^{\circ} \mathrm{F} (Round to nearest degree as needed.)

Studdy Solution
Substitute back into the model: T=34+38×0.6337 T = 34 + 38 \times 0.6337 T=34+24.0706 T = 34 + 24.0706 T58 T \approx 58
The temperature of the ginger ale after 15 minutes is approximately:
58F \boxed{58^{\circ} \mathrm{F}}
