2. A climbing vine is taking over the side of a building. At first the vine only covered 10% of the building, but after 4 years it covered 48%. The vine grows at a rate proportional to the percentage of the building that is not covered. Let V be the percentage of the building covered with the vine (so V(0) = 10), and let t be time in years. %3D (a) Which differential equation correctly models this situation? Why? AP = k(100 – V) AP = 100 – kV %3D dt dt
