2/3 = 8/12
reason:
2/3 * 4/4
Step-by-step explanation:
20% of the length is 23 cm
100% of the length is 23×5 = 115 cm
For this case we have the following function:
![A (t) = A0e ^ {(kt)} ](https://tex.z-dn.net/?f=A%20%28t%29%20%3D%20A0e%20%5E%20%7B%28kt%29%7D%0A)
Where,
A0: initial population
K: rate of change
t: time in years
Substituting values we have:
![A (t) = 22000 * e ^ {(- 0.021 * t)} ](https://tex.z-dn.net/?f=A%20%28t%29%20%3D%2022000%20%2A%20e%20%5E%20%7B%28-%200.021%20%2A%20t%29%7D%0A)
For the year 2015 we have:
