Answer:
Step-by-step explanation:
The constant rate of growth is the slope of the line that models this situation. We need to come up with 2 coordinates that model the info given. After 3 years, the height was 3.87 feet. In a coordinate pair, that is (3, 3.87). Likewise with the other info. After the 6th year, its height was 7.74 which is (6, 7.74) in a coordinate pair. Filling in the slope formula to find the constant rate of growth:
[tex]m=\frac{7.74-3.87}{6-3}=\frac{3.87}{3}=1.29[/tex]
That tells you that the growth rate of the tree is 1.29 feet per year.
