A spherical snowbalt is melting in such a way that its radius is decreasing at rate of 0.3 cm;r min. At what rate is the volume of the snowball decreasing when the radius is 1? cm. {Note the answer is a positive number]. . . cm" The volume is decreasing by , {enter - mm your answer rounded to 3 decimal places] BI At noon, shipAis 10 nautical miles due west of ship B. Ship A is sailing west at 15 knots and ship B is sailing north at 23 knots. How fast [in knots] is the distance between the ships changing at TP' PM? (Note: 1 knot is a speed of 1 nautical mile per hour.) ' knots [round your answer to three decimal places} C) Gravel is being dumped from a conveyor belt at a rate of 10 cubic feet per minute. It forms a pile in the shape of a right circular cone whose base diameter and height are always equal. How fast is the height of the pile increasing when the pile is 23 feet high? The height of the pile is increasing by ft (round your answer to 3 decimal places) min D) A plane flies at a speed 560 km/hr at a constant height of 19 km. How rapidly is the angle of elevation to the plane changing when the plane is directly above a point 130 km away from the observer? The angle of elevation is changing at radians/hr (enter a positive value). Round your answer to 3 decimal places. E) cm3 A spherical snowball is melting at a rate of 8.3 . How rapidly is the min radius decreasing when the snowball's volume is 4500 m cm"? The radius is decreasing by cm/min. (Your answer should NOT be a signed number, and should be rounded to 3 decimal places)F) A particle moves along the curve y = 4x + 8x - 4 in such a way that as it moves, dt = -9 units/minute. When the particle reaches the point (7, 248) it is moving Select an answer the origin at a rate of units/minute.

How rapidly is the point where the beam meets the shoreline moving along the shoreline when the beam meets the shoreline at a point 1300 meters from the lighthouse? m/s (enter your answer rounded to 3 decimal places) H) Two cars are moving towards an intersection. One car is 150 meters north of the intersection and moving towards the intersection at 12 m/s, while the other is 190 meters west of the intersection and moving towards the intersection at 11 m/s. How rapidly are the cars approaching each other 5 seconds later? The cars are getting Select an answer v at m/s. Enter your answer rounded to 3 decimal places.A tank leaks 0.01 of oil into a lake. The oil forms a semicircular disk hr with a thickness of 10" meters. How rapidly is the radius of the disk increasing when the radius is 130 meters? The radius of the disk is increasing by m/hr (round your answer to 3 decimal places) m3 A tank leaks 0.08 of oil into a lake. The oil forms a semicircular disk hr with a thickness of 10 " meters. How rapidly is the radius of the disk increasing 2 hours after the tank begins leaking? The radius of the disk is increasing by m/hr (round your answer to 3 decimal places)
