Thank you!!

A discrete model 1 for Newton's Law of Cooling is yk+1 - yk = dt*c*(ysur - yk) yk+1 - yk = dt*c*ysur - yk y'(t) = c (ysur - y(t)) y'(t) = c* ysur - y(t)) yk+1 - y = c (ysur - y(t)) A continuous model 1 for Newton's Law of Cooling is yk+1 - yk = dt*c*(ysur - yk) yk+1 - yk = dt*c*ysur - yk y'(t) = c (ysur - y(t)) y'(t) = c* ysur - y(t)) yk+1 - y = c (ysur - y(t)) A solution of the differential equation y' = (1/26)(70 - y) is y(t) = 70 + 130 e(-1/26)t y(t) = 70 + 130*exp(-t/26) y(t) = 70 +140 e(-1/26)t all of the above
