A culture of bacteria has an initial population of 15000 bacteria and doubles every 3 hours. Using the formula P_t = P_0\cdot 2^{\frac{t}{d}}P t =P 0 ⋅2 d t , where P_tP t is the population after t hours, P_0P 0 is the initial population, t is the time in hours and d is the doubling time, what is the population of bacteria in the culture after 20 hours, to the nearest whole number?

Step-by-step explanation:
Given the function
P(t) = P0 * 2^t/d
P0 = 15000 ; d = 3.; t = 20
P(20) = 15000 * 2^20/3
P(20) = 15000 * 2^6.66666
P(20) = 15000 * 101.59366
P(20) = 1523905.0
P(20) = 1523905

To find the area of the rectangular prism, use the formula:
A = width x height x length
A = 2 x 2 x 3
A = 12
Now multiply A with 0.75
12 x 0.75 = 9
x = 9 in³
hope this helps
