A population of bacteria is growing exponentially. At noon, the population was 3700. By 4 PM, the population had reached 5000. (Use the exponential growth model B(t) = Pe ", where t is in hours.) A) Find k. Round to 8 decimal places. O A. 0.08783784 O B. 0.07527627 O C. 0.06500000 O D. 0.05589394 O E. None of these B) How long (past noon) will it take for the population to reach 6450? ROUND YOUR ANSWER TO 1 DECIMAL PLACE. (i.e. 3.4) The population will reach 6450 in about hours
