A bacterial population has an exponential growth rate of 11.2% per hour. If there were 480 bacteria initially, what would the ba

faust18 [17]

The number of bacterial population after 5 hours is; 816

The formula for the exponential growth of the population is;

N(t) = N_o(1 + r)^(t)

Where;

N(t) is number of bacteria after t hours

N_o is number of bacteria initially

r is growth rate

t is time

We are given;

N_o = 480

r = 11.2% = 0.112

t = 5

Thus;

N(5) = 480(1 + 0.112)^(5)

N(5) = 816.14

Approximating to a whole number gives; N(5) = 816 bacteria

Put this in one of the equations again.

$ y=-2(2)+7$

$\implies y=-4+7= \boxed{3}$
