A culture started with 1,000 bacteria. After 3 hours, it grew to 1,100 bacteria. Predict how many bacteria will be present after

ss7ja [257]

The general equation for exponential growth can be written as:
$x_{t} = x_{0} (1+r)^{t}$
where r is the growth rate.
Plugging in the given values, we get:
$1100=1000(1+r)^{3}$
Therefore
$(1+r)^{3}=1.1$
giving
$1+r= \sqrt[3]{1.1} =1.0323$
The predicted number of bacteria after 17 hours is given by:
$1000(1.0323)^{17}=1716$

I solved it myself and my result is (n+1)/n. Why is that 1/2 there? An explanation would be great if possible. Thanks!

Answer:

The product of (k + 1) series starts with 3 (because k = 2) and you need 2 to be multiplied to this in order to get (n + 1)!

Therefore you need to multiply 2 and 1/2 to make it right. 2 completes the factorial and 1/2 remains.

Hope it was clear explanation.
