Two cars are approaching an intersection on roads that are perpendicular to each other. Car A is north of the intersection and traveling south at 40 mph. Car B is east of the intersection and traveling west at 45 mph. How fast is the distance between the cars changing when car A is 12 miles from the intersection and car B is 5 miles from the intersection? (Round your answer to two decimal places.) Em For a particular type of crab, the allometric relationship between the weight C of the claw and the weight W of the body is given by c = 0.11W1'5?. Find the rate of change of the claw weight in terms of the rate of change of the body weight for ddler crabs. -x (2?) A point is moving along the graph of the equation y = -3x3. At what rate is y changing when x = 8 and is changing at a rate of 3 units/sec? -216 X units/sec
