A culture of bacteria has an initial population of 74000 bacteria and doubles every 3 hours. Using the formula Pt = P0 • 2^t/d where Pt is the population
after t hours, P0 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 13 hours,
to the nearest whole number?

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
