According to Poiseuille's laws, the velocity V of blood is given by V = k (R" - r" ) where R is the radius of the blood vessel, r is the distance of a layer of blood flow from the center of the vessel, and K is a constant. A patient takes blood vessel dilation medication so that her blood velocity is modeled by Poiseuille's law with k = 570.1. Find the rate of change of the blood velocity when R =0.01 mm and R is changing at 0.004 mm per minute. Assume r is constant. The blood velocity is increasing at | mm per minute each minute. Round to the nearest thousandth as needed.)
