Question 1193870: In a controlled experiment, the temperature T°C of a liquid, t hours after the start of an experiment is T = 25 + (e^0.4t), 0 < t < 12.
a) Sketch the graph of temperature T for 0 < t < 12.

b) State the temperature halfway through the experiment to the nearest 0.1 °C.
Halfway through experiment is t = 6
c) Find the time at which the temperature of the liquid reaches 100 °C. Give answer in hours and minutes, to the nearest minute.
T - 100 is reached at t=10.8 hours or 10 hours and 48 minutes

Halfway through experiment is t = 6 and T = 36.2 degrees
T - 100 is reached at t=10.8 hours or 10 hours and 48 minutes
