2 Select the correct answer. The bacterium, cholera, reproduces at an exponential rate which can be modeled through the continuous growth model. If the value for k Is 1.38 and we Initially start with 2 bacteria, what Is the equation for cholera growth, where tis the number of hours? OA At= 2el.38xt O B. A,= 2el.38x2t OC. A,=-2el.38xt OD. A, = 2e-1.38xt
