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 = 1 + 1 7 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 2) = 8 and ty(3, 2) = 7. how fast is the temperature rising on the bug's path after 7 seconds? (round your answer to two decimal places.)
