Answer:
<em>The birch tree needs 12 years</em>
Step-by-step explanation:
<u>Proportional Relationship</u>
Two variables t and d are proportional if they have the relationship described by the equation:
d = kt
Where k is the constant of proportionality.
From the graph on the question, we recognize the proportionality of the age of a birch tree and its diameter because the line passes through the origin (0,0). To find the equation, we need to recognize a clear point on the graph. We select the point (2,7). Substituting in the equation:
7 = 2k
Thus:
![k=\frac{7}{2}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B7%7D%7B2%7D)
The equation is:
![\displaystyle d=\frac{7}{2}t](https://tex.z-dn.net/?f=%5Cdisplaystyle%20d%3D%5Cfrac%7B7%7D%7B2%7Dt)
For the birch to have a diameter of d=42 inches, the time needed can be calculated by solving the equation:
![\displaystyle 42=\frac{7}{2}t](https://tex.z-dn.net/?f=%5Cdisplaystyle%2042%3D%5Cfrac%7B7%7D%7B2%7Dt)
![\displaystyle t=42*\frac{2}{7}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20t%3D42%2A%5Cfrac%7B2%7D%7B7%7D)
t = 12 years
The birch tree needs 12 years
Answer:
3. Some of the non living or abiotic factors in this picture are the water, the sky, fallen tree, and the sun.
4. The living organisms might interact with the non living parts of the environment by using them as shelter or a necessary resource (like water).
