Answer:
The nail would be 30 feet above the ground in 10 years.
Step-by-step explanation:
We are given the following in the question:
Height of nail = 10 feet.
The tree grows taller at a rate of 2 feet per year.
Thus, the height of nail can be represented by a linear function:
[tex]h(t) = 10 + 2t[/tex]
where t is the number of years.
We have to find the height of nail in 10 years.
Putting t = 10, we get,
[tex]h(10) = 10 + 2(10)\\h(10) = 30[/tex]
Thus, the nail would be 30 feet above the ground in 10 years.
