Answer from: laylay120

The answer is; 96

Use the following formulae; P(t) = P(0) * e ^rt

P(t) = 3 * 2 ^ 5 = 96

This type of growth is called exponential growth

Answer from: Frenchfries13

Explanation:

The population of bacteria can be calculated by using the following formula

$P = P_0 * e^{rt}\\$

Where,

P represents the Population after time period "t"

P_0 represents the initial population at t = 0

r represents the rate at which population is growing

and t represents the time period in which P_0 will become P

Given -

$P_0 = 3\\r = 2 \\t = 5$

Substituting the given values in above equation, we get -

$P = 3 * e^{2 * 5}\\P = 96$

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
