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:
where t is the number of years.
We have to find the height of nail in 10 years.
Putting t = 10, we get,
Thus, the nail would be 30 feet above the ground in 10 years.
The weekly earning is an illustration of a linear function.
Her total earning when she sells a good worth $4800 is $637
The given parameters are:
Let the total sales be x and the total earnings be y.
So, we have:
Substitute known values
When she sold merchandise worth $4800, it means that <em>x = 4800</em>
So, we have:
Hence, her total earning is $637
