The temperature on a flat surface is given by T(B, y). At the point (2,1), the temperature is T(2, 1) = 5 degrees. Also T3; (2, 1) = 4 degrees/cm, and Ty(2, 1) = 3 degrees/cm. Use a linear approximation to estimate the temperature at (33,14) : (2. 2, 0. 7). OT(2.2, 0. 7) m 6.7 T(2.2, 0.7) $4.9 OT(2.2, 0. 7) z 3.7 T(2.2, 0.7) w 5.1
