Asample of water with mass of 587.00 is heated with 87 kj of energy to a temperature of 518.4 k. the specific heat of water is 1 j-1 kg k-1. what is the initial temperature of the water?

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.)
