Two variable quantities A and B are found to be related by the equation given below. What is the rate of change dA / dt at the moment when A = 2 and dB / dt = 1? AB + BS = 35 dA when A = 2 and dB / dt = 1. dt (Simplify your answer.)\fA circle is growing, its radius increasing by 3 mm per second. Find the rate at which the area is changing at the moment when the radius is 27 mm. When the radius is 27 mm, the area is changing at approximately (Round to the nearest thousandth as needed.)
