The concentration of pollutant bacteria e in a lake decreases according toc = 70 e 1.5t + 25 e-0.075tDetermine the time required (t) for the bacteria concentration to be reduced to c = 9 usingNewton-Raphson method to within E = 28%. Use initial guess of t = 0.

Given c = 9, then 9 = 70e-1.5t+25e-0.075t, we can rewrite it as f(t) = 70e-1.5t+25e-0.075t-9
