Given the equation:
You know that the radioactive substance has this half-life (in years)
And:
Therefore, you can rewrite the equation in this form in order to find "k":
Solve for "k":
Answer:
2/3
Step-by-step explanation:
1/3 multiplied by 2 equals 2/3
This is based off this year so 1990-2017
Since there are 27 years it would be 2300*27 which would equal 62,100 people
The new births would be 375,000(1.013)^27 which would equal 531,479 people
Adding 531,479 with 62,100 equals 593,579 people
