Write the exponential function y = 250e-0.21t in the form y = abt. (a) Once you have rewritten the formula, give b accurate to at least four decimal places. b = -0.8105 help (numbers) If t is measured in years, indicate whether the exponential function is growing or decaying and find the annual and continuous growth/decay rates. The rates you determine should be positive in both cases of growth or decay (by choosing decay the negative rate is implied). (b) The annual decay rate is % per year (round to the nearest 0.01%). (c) The continuous decay rate is % per year (round to the nearest 0.01%)
