The height of a cone is increasing at a constant rate of 6 meters per minute, and the volume is decreasing at a rate of 301 cubic meters per
minute. At the instant when the height of the cone is 7 meters and the
volume is 566 cubic meters, what is the rate of change of the radius?
The volume of a cone can be found with the equation V p2h.
Round your answer to three decimal places.

An oil exploration company currently has two active projects, one in asia and the other in europe. let a be the event that the asian project is successful and b be the event that the european project is successful. suppose that a and b are independent events with p(a) = 0.2 and p(b) = 0.8. (a) if the asian project is not successful, what is the probability that the european project is also not successful? (b) what is the probability that at least one of the two projects will be successful? (c) given that at least one of the two projects is successful, what is the probability that only the asian project is successful? (round your answer to three decimal places.)
