Solve the problem.
A dish of lasagna baked at 350°F is taken out of the oven into a kitchen that is 73°F.
After 7 minutes, the temperature of the lasagna is 291.3°F. What will its temperature
be 15 minutes after it was taken out of the oven? Round your answer to the nearest
degree.

Step-by-step explanation:

So:

T(7)=68+(350-68)e^-kt

299.8=68+282e^-7k

e^-7k=0.82198581560283687943262411347518

ln e^-7k=ln 0.82198581560283687943262411347518

-7k=-0.1960321400324622534737708260656

k=0.02800459143320889335339583229509

Then:

T(12)=68+(350-68)e^-12(0.02800459143320889335339583229509)

T(12)=68+(282)0.71458373316960990812286116751929

T(12)=269.512 degrees 12 minutes out of the oven.

i think this could be a possible answer (1 / 84) -1

good luck! : d
