The height of a triangle is measured as 28.5 cm, with the base measured as 18.4 cm. The measurement of the height can be off by as much as0.8 cm, and that of the base by no more than1.9 cm. Estimate the maximum possible error in calculating the area of the triangle. 

Thus, the maximum possible error in calculating the area of the triangle is approximately cm². 

The temperature reading T (in C°) at time t (in s) of a thermometer initially reading 50^∘Cand then placed in water at 10C° is found by solving the equation dT + 0.15 (T−10) dt =0. Solve for T as a function of t. 

T=
