Which equation is most likely used to determine the acceleration from a velocity vs. time graph? t O a= AV m V2-71 X2-X a= AV 쁜 Om X2-X1 V2-71 (this is what interpreted the question to be, but its not what it is..)​

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.)
