Answer:

B) Radiometric dating

Explanation:

Radiometric dating: Is a method used to date material such as rocks or fossil by comparing its radioactive isotope material contained in it with the amount of it's decay products. Since the decay occurs at a constant rate Scientists/Geologists are able to obtain it's relative age.

Answer: Option B.

Radiometric dating.

Explanation:

Radiometric dating is a technique used by geologists gist to determine the relative age of rock through their decay rate or the decay of their radioactive elements which occur naturally when they are formed.

The radioactive decay is the process where the atomic nucleus that is not stable losses energy through radiation.

The rate at which the concentration of a drug in the bloodstream decreases is proportional to the concentration at any time t. I
Westkost [7]

Answer:

C(t) = C_oe^{-kt}

Explanation:

From the given information:

At any given time (t), let c(t) represent the concentration of the drug present in bloodstream.

Deriving the equation:

\dfrac{dC}{dt} decrease proportionally to Concentration C

i.e

\dfrac{dc}{dt} \alpha - C

\dfrac{dc}{dt} = -k C

\dfrac{dc}{c} = -k dt

\int \dfrac{dc}{c} = -k \int dt

㏑(C) = -kt + λ

where,

λ is the integration constant.

Integrating at t = 0, concentration of blood = Co g/mL

C(0) = Co

㏑(C₀) = 0 + λ

λ = ㏑(C₀)

From ㏑(C) = -kt + λ

㏑(C) = -kt + ㏑C₀

㏑(C)  - ㏑C₀ =  -kt

\dfrac{C}{C_o} = e^{-kt}

C(t) = C_oe^{-kt}

∴

The concentration of drug in blood at any time t is:

C(t) = C_oe^{-kt}
