I do not know how to find part b of this problem can anyone help me.
When a cold drink is taken from a refrigerator, its temperature is 5°C. After 25 minutes in a 20°C room its temperature has increased to 10°C. (Round the answers to one decimal place.)
(a) What is the temperature of the drink after 35 minutes?
°C
(b) When will its temperature be 16°C?
minutes
your equation is incorrect. if y is the temperature, then ...
y(0) should = 5
y(25) should = 10
your equation does not yield those values for the given times.
you should be deriving the temperature function from Newton's law of cooling/heating ...
, using the initial conditions y(0) = 5 and y(25) = 10
