(a) If the temperature of the turkey is 150°F after half an hour, what is the temperature after 50 minutes?
T(50) =

(b) When will the turkey have cooled to 105°?
t = min

anonymous · Answer

for (a)..Find the equation relating time and temp:
intercept = 185
slope + (185-150)/(0-30) = -35/30 = -7/6

then...Equation: f(t) = (-7/6)t+185
what is its temperature after 50 min? 
f(50) = (-7/6)(50)+185 = ?

anonymous · Answer

& for (b)...make 105 the subject of f(t) = (-7/6)t + 185
eg. 105 = (-7/6)t+185
(-7/6)t = -80
t = ? minutes.
