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.
Answer:
c = 80:)
Step-by-step explanation:
Answer: 120
Step-by-step explanation:
Given : the total number of digits : 5
The number of permutations of n things taken r at a time is given by :-
By using permutation, the number of different 4-digit numerals can be made from the digits of 56987 is given by :-
Hence, the number of different 4-digit numerals can be made from the digits of 56987 is 120 .
The equation of the line is y=mx+b
so now you can substitute:
3=1/5(-1)+b
3= -1/5+b
now add 1/5 on both sides
3 1/5=b
so the final equation is
y=1/5x+3 1/5
hope this helps!
