Transcribed Image Text:32)A pan ofboiling water is set in a cold room. The function T(h) 2080(0.23)" gives the
temperature in °C of the water after h hours.
a) Find the temperature of the water after 1.5 hours.
b) How long does it take the water to reach 30°C?
Expert Solution
Step 1
Here, we substitute the value h=1.5, to get the required value of temperature.
Step 2
Now, we substitue T=30 and solve the equation to get the value of h as shown on board.
