Use the two points to find the growth rate, k. Write an exponential model for each point, then solve this system of two equations for k. 2. Use either point with the k you found to find the initial amount at time zero, A,. . Doubling time is when the amount is 2*A,. 4. Use the values of k and A, to calculate the amount for a given time or to find the time to reach a specific amount in the future. w The count in a bacteria culture was 200 after 15 minutes and 1300 after 30 minutes. Assuming the count grows exponentially. You may enter the exact value or round to 2 decimal places. What was the initial size of the culture? [:] Find the doubling period. :] Find the population after 90 minutes. [: When will the population reach 11000. S Question Help: []Video 1 (] Video 2 LT AT
