The number N of bacteria after t hours is N(t) = A * 2^t. Initially, there are 125 bacteria. How many are there after 6 hours?
Added by Sergio K.
Step 1
So we can write the equation as 125 = A * 2^0. Since anything to the power of 0 is 1, we can simplify this to A = 125. Now we know the value of A, we can substitute it into the equation to find the number of bacteria after 6 hours. So N(6) = 125 * 2^6 = 8000. Show more…

The number of bacteria, $N(t),$ in a culture $t$ hr after the bacteria is placed in a dish is given by $$N(t)=5000 e^{00617 t}$$ a) How many bacteria were originally in the culture? b) How many bacteria are present after 8 hr?

Suppose that at time $t=0$ there are 750 bacteria in a growth medium and the bacteria population $y(t)$ grows at the rate $y^{\prime}(t)=802.137 e^{1.528 t}$ bacteria per hour. How many bacteria will there be in 12 hours?
