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 = 2 + t , y = 5 + 1 2 t, where x and y are measured in centimeters. the temperature function satisfies tx(2, 6) = 6 and ty(2, 6) = 5. how fast is the temperature rising on the bug's path after 2 seconds? (round your answer to two decimal places.) °c/s
