Answer:
x=45
Step-by-step explanation:
2x+45+x=180
Combine 2x and x to get 3x.
3x+45=180
Subtract 45 from both sides.
3x=180−45
Subtract 45 from 180 to get 135.
3x=135
Divide both sides by 3.
x=135/3
Divide 135 by 3
x=45
Answer:
Differential equation: , , , .
Solution:
Step-by-step explanation:
Let suppose that rate of change of the amount of Carbon-14 atoms are directly proportional to the current amount of Carbon-14 atoms. That is:
Where:
- Amount of Carbon-14 atoms, dimensionless.
- Proportionality constant, measured in .
must be negative as death rate is constant and birth rate is zero. (). Dimensionally, we can rewritte this constant as following:
Where is the time constant (), measured in years.
We can find the solution of the ordinary differential equation by separating each variable:
Where is the initial amount of atoms of Carbon-14.
