A hard-boiled 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℃ ?

**bobpursley**, Sunday, April 6, 2014 at 3:36pmP, 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 38-ln18=ln80-5k

solve for k
