Answer:
BC = 24
Step-by-step explanation:
In the picture attached, the missing triangles are shown:
<u>Data</u>
- AB = 10
- BD = 5
- DE= 12
- Then, AD = 10-5 = 5
As a consequence of the "Side Splitter" Theorem:
AD/DE = AB/BC
Replacing with data and solving for BC
5/12 = 10/BC
BC = 10*12/5 = 24
The given population models for the trees is given as:
It is required to find which forest will have a greater number of trees after 20 years and by how many.
To do this substitute t=20 in the equations of the models:
Hence, forest A has a greater number of trees after 20 years.
Calculate the difference:
It follows that forest A has a greater number of trees than forest B by 43 trees.
After 20 years, forest A has a greater number of trees than forest B by 43 trees.
