Water is boiling at 1 atm pressure in a stainless steel pan on an electric range. it is observed that 2 kg of liquid water evaporates in 30 min. the rate of heat transfer to the water is: 2.97 kw o 0.47 kw 3.12 kw 2.51 kw 2.32 kw

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 = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)
