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.
Answer:use math-way it will give the answer
Step-by-step explanation:
C is the answer because 2.7 minus .9 is 1.6
The Answer is
70 x 4.00 = $ 280.00 adults
85 x 2.50 = $ 212.50 students
= $ 492.50
Answer:
Step-by-step explanation:
8n + 6 = 8*1 + 6 = 8 + 6 = 14
2(4n + 3) = 2*(4*1 + 3) = 2*(4 + 3) = 2*7 = 14
14n = 14*1 = 14
