The circulation time of a mammal (that is, the average time it takes for all the blood in the body to circulate once and return to the heart) is proportional to the fourth root of the body mass of the mammal. The constant of proportionality is 17.40 if circulation time is in seconds and body mass is in kilograms. The body mass of a growing child is 44 kg and is increasing at a rate of 0.2 kg/month. What is the rate of change of the circulation time of the child? Round your answer to three decimal places. The rate of change of the circulation time is i seconds/month.Current Attempt in Progress A ruptured oil tanker causes a circular oil slick on the surface of the ocean. When its radius is 190 meters, the radius of the slick is expanding by 0.1 meter/minute and its thickness is 0.02 meter. At that moment: (a) How fast is the area of the slick expanding? Round your answer to three decimal places. HI m2/min (b) The circular slick has the same thickness everywhere, and the volume of oil spilled remains fixed. How fast is the thickness of the slick decreasing? Round your answer to six decimal places. m/minCurrent Attempt in Progress A potter forms a piece of clay into a cylinder. As he rolls it, the length, L, of the cylinder increases and the radius, r, decreases. If the length of the cylinder is increasing at 1.0 cm per second, find the rate at which the radius is changing when the radius is 1 cm and the length is 5 cm. Enter the exact answer. The rate at which the radius is changing is i cm/sec
