A boat is being pulled toward a clock as shown in the figure to the right. If the rope is being pulled in at the rate of 1 foot per second, how fast is the distance between the dock and the boat decreasing when it is Boat Dock 2 feet from the dock? Rope 5 ft E) The distance between the dock and the boat is decreasing by D feet per second when the boat is 2 feet from the dock. (Round to the nearest thousandth as needed.) A rock is thrown into a still pond. The circular ripples move outward from the point of impact of the rock so that the radius of the circle formed by a ripple increases at the rate of 5 feet per minute. Find the rate at which the area is changing at the instant the radius is 18 feet. <: when the radius is feet area changing at approximately square per minute. to nearest thousandth as needed.>
