The temperature at a point (x, y) is T(x, y), measured in degrees Celsius. A bug crawls so that its position after t seconds is given by x = sqrt(1 + t) , y = 8 + 1 /8 t, where x and y are measured in centimeters. The temperature function satisfies Tx(3, 9) = 9 and Ty(3, 9) = 1. How fast is the temperature rising on the bug's path after 8 seconds? (Round your answer to two decimal places.)
