You are testing a vehicle fuel gauge float. the float pulls 40ma when the tank is 100% full and 2ma when the tank is empty. assuming that the float's resistance scales linearly between 0% and 100% full, what current draw in milliamps should we see if we set the float to 49% full? give your answer to the tenth of a milliamp.

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.)
