a tree 5 ft tall growns an average of 8 in each year, write an ewquation to model the trees height h inches after y years
h = 60 + 8y
To write an equation that models the tree's height, we need to establish the relationship between the tree's height and the number of years it has grown.
Given that the tree starts at a height of 5 ft and grows an average of 8 inches each year, we can convert the initial height to inches, as follows:
Initial height in inches = 5 ft * 12 inches/ft = 60 inches.
Let's represent the height of the tree after y years as h inches.
Since the tree grows an average of 8 inches each year, we can write the equation as follows:
h = 60 + 8y.
The equation h = 60 + 8y models the tree's height h inches after y years.
