WebIn this problem, we are given that it takes 444 years for the substance to lose 1/2 of its radioactive nuclei, so in each year, it will tick through only one-444th of its half-life. So our exponent is t/444. We then can say that N (t) = N₀ (1/2) ^ (t/444) You asked what the constant value is for mercury 194. http://people.ku.edu/~k088m880/Math115/Chapter0506.pdf

WebNov 5, 2014 · In general, if the rate of transmission as a percent is r %, then the number used in repeated multiplication would be 1 + r/100. For example, if the transmission rate is 6 percent, use 1 + 6/100 = 1.06; if r = 50%, use 1 + 50/100 = 1.5. This repeated multiplication can be expressed using exponential functions. WebExponential functions are useful in modeling many physical phenomena, such as populations, interest rates, radioactive decay, and the amount of medicine in the bloodstream. An exponential model is of the form A = A 0 (b) t/c where we have: A 0 = the initial amount of whatever is being modelled. t = elapsed time. A = the amount at time, t.
