You are conducting a biology experiment and begin with 5000000 cells, but some of those cells are dying each minute. The rate of death of the cells is modeled by the function \( A(t)=A_{0} \cdot e^{-.598 t} \), where \( A_{0} \) is the original number of cells, \( t \) is time in minutes, and \( A \) is the number of cells remaining after \( t \) minutes. How many cells remain after 5,10 , and 25 minutes? Round each answer to the nearest cell. There are Submit Question
