A construction crew is lengthening a road that originally measured 55 miles. The crew is adding one mile to the road each day.The length, L (in miles), after d days of construction is giving by the following function.
L(d)=55+d
What is the length of the road after 21 days?
To find the length of the road after 21 days, we substitute d = 21 into the function L(d) = 55 + d:
L(21) = 55 + 21 = 76
So, the length of the road after 21 days is 76 miles.
To find the length of the road after 21 days, we can substitute d = 21 into the equation L(d) = 55 + d:
L(21) = 55 + 21
L(21) = 76
So, the length of the road after 21 days is 76 miles.
To find the length of the road after 21 days, you can use the given function:
L(d) = 55 + d
where L(d) represents the length of the road after d days.
To find the length after 21 days, substitute d = 21 into the function:
L(21) = 55 + 21
Now, you just need to calculate the value of L(21):
L(21) = 76
Therefore, the length of the road after 21 days of construction is 76 miles.
