- dt The Gompertz growth model is commonly used to model tumor cell growth. Let v(t) be the tumor's volume, then du(t) = A e-atv(t) where λ and a are two appropriate constants. (a) Verify that the solution is given by v(t) = voe/a(1-e-at), where vo is the initial tumor volume. (b) This model takes into account the fact that when nutrients and oxygen are scarce at the tumor's core, its growth is impaired. Find the final predicted tumor volume (let too). (c) For a specific mouse tumor, it was experimentally found that λ = 2.5 days, a = 0.1 days with vo = 50 x 10³ mm³. Use any method available to make a plot of v(t) vs t.
