An immunologist is studying the immune response to cancer and observes that a particular treatment doubles the number of active T-cells every 5 days. If the initial count of active T-cells is 1,000, how many active T-cells will there be after 20 days? Use the formula for exponential growth: \( N(t) = N_0 \times 2^t/T \), where \( T \) is the doubling time. Calculate \( N(t) \). - go-checkin.com
