A hardboiled egg at 98℃ is placed in a sink of 18℃ water to cool. After 5 minutes, the eggs temperature is found to be 38° C.
a) Find the value of P in Newton’s Law of Cooling.
b) Find the value of the constant k rounded to nearest hundredth.
c) What is the temperature after 3 minutes?
d) How long does it take the egg to cool to 25℃ ?

P, k? wouldn't that depend on how it is written, and in what language?
T(t)=18+80e^kt
I have no idea what you mean as P.
for k, 38=18+80e^k5
ln 38ln18=ln805k
solve for k
