Question

A spruce tree was measured three years after sprouting at a bright of 3.87 feet after its sixth year the tree reached a height of 7.74 what is the constant rate

Answer 1

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:

`m=(7.74-3.87)/(6-3)=(3.87)/(3)=1.29`

That tells you that the growth rate of the tree is 1.29 feet per year.
