(1 point) Let S(t) represent the amount of a chemical reactant present at time t, where t≥0. Assume that S(t) can be determined by solving the initial value problem S′=−aSK+S and S(0)=S0, where a, K, and S0 are positive constants. Obtain an implicit solution of the initial value problem. (The differential equation, often referred to as the Michaelis-Menten equation, arises in the study of biochemical reactions.) Enter the constant S0 as S0 (with a zero, not the letter O).

Darla claims that the first periodic table developed by mendeleev was not completely accurate, so it is not useful at all. harmony argues that it establish the periodic table we use today, making it more credible. who is correct and why? darla is correct, because a model that has any mistakes should be thrown out. darla is correct, because a good model would not need to change. harmony is correct, because mendeleev’s model had all of the information correct in the first version. harmony is correct, because mendeleev’s model made predictions that came true.
