If a particle's position is given by x = 4 − 12 t + 3 t^ 2 (where t is in seconds and x is in meters), what is its velocity at s t = 1 s ? b) is it moving in the positive or negative direction of x just then? c) what is its speed just then? d) is the speed increasing or decreasing just then? (try answering the next two questions without further calculations.) e) is there ever an instant when the velocity is zero? if so, give the time t ; if not, answer no. f) is there a time after t = 3 s when the particle is moving in the negative direction of x ? if so, give the time t ; if not, answer no.

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.)
