CalculusQ&A LibraryAn object is heated to 191"F and is then allowed to cool in a room whose air temperature is 60 F. Thetemperature u of the object t minutes after being placed in the room is given byu(t) = 60+131e 0.0275e(a) What will the temperature of the object be after 7 mninutes?(b) How long will it take until the temperature of the object is 69 F?Question

Step 1

Given:

‘u’ is the temperature and ‘t’ is time

Step 2

Part (a)

Here, put t = 7

So, temperature of the object after 7 minutes:

Step 3

Part (b)

Put u (t) = 69

So, the time it takes until t...
