A liquid is cooling such that its temperature can be modeled by the function f(m) = 112e^(-0.058m) + 64, where the output is in Fahrenheit and m represents the minutes the liquid has been cooling. Which of the following is closest to the amount of time it will take for the temperature to reach 90 degrees?
Added by Jorge G.
Step 1
90 = 112e^(-0.058m) + 64 Subtract 64 from both sides: 26 = 112e^(-0.058m) Divide both sides by 112: Show more…

A container of hot liquid is placed in a freezer that is kept at a constant temperature of 20 degrees Fahrenheit. The initial temperature of the liquid is 180 degrees Fahrenheit. After 5 minutes, the liquid's temperature is 68 degrees Fahrenheit. How much longer will it take for its temperature to decrease to 34 degrees Fahrenheit. Newton's Law of Cooling : T = (T_0 - T_s) e^{-kt} + T_s

A hot liquid kept in a beaker cools from $80^{\circ} \mathrm{C}$ to $70^{\circ} \mathrm{C}$ in 2 minutes. If the surrounding temperature is $30^{\circ} \mathrm{C}$, then the time of cooling of the same liquid from $70^{\circ} \mathrm{C}$ to $50^{\circ} \mathrm{C}$ : (a) $4 \mathrm{~m}$ (b) $6 \mathrm{~m}$ (c) $8 \mathrm{~m}$ (d) $10 \mathrm{~m}$
