Um the brainliest answer would be appreciated greatly :)
Answer:
a. 8.1 milligrams
b. 40.07 hours
c. 8.859 milligrams
Explanation:
If a person takes a prescribed dose of 10 milligrams of Valium, the amount of Valium in that person's bloodstream at any time can be modeled by
Where A(t) = amount of Valium remaining in the blood after t hours
t = time or duration after the drug is taken
a. we have to calculate the amount of drug remaining in the bloodstream after 12 hours
= 10×0.81253
= 8.1 milligrams
b. In this part we have to calculate the time when A(t) = 5 milligrams
0.5 = 
Now we take natural log on both the sides of the equation.
ln(0.5) = ln(
-0.69314 = -0.0173t
t = 
t = 40.0658
≈ 40.07 hours
c. In this part we have to calculate the rate, by which amount of drug will decay in the bloodstream after 7 hours.
= 10×0.8859
= 8.859 milligrams
Smoking is one of the major reason of Lung cancer. But one may have cancer even if the individual is not a smoker due to radiation, secondary air pollutants.
<h3> What is cancer?</h3>
Cancer is described as the uncontrolled and abnormal growth of cells in one’s body which are arrested in the growth phase of the cell cycle and multiply rapidly and does not mature like normal cells, cancer is more aggressive form of a tumour.
The following describe the relation of smoking with lung cancer
- Cancer is caused by oncogenes activating substances [OAS] some of them causes mutation in the body
- These oncogenic substances in the smoke produced while smoking contains nicotine, hydrocarbons, cyclohydrocarbons and various other factors which converts normal cells into cancerous cells
- Hence,
- smoking
- causes
- oral
- and
- lung
- cancer
