Answer:
3
Step-by-step explanation:
The expression can be simplified and then evaluated at h=0.
((1 +h)^3 -1)/h = (1 +3h +3h^2 +h^3 -1)/h
= (3h +3h^2 +h^3)/h
= 3 +3h +h^2
This evaluates to 3 when h=0.
The limit of interest is 3.
_____
Strictly speaking, the simplified form is only valid when h ≠ 0. However, that form is useful for finding the limit.
Answer:
Unit price = $1.31/roll
Step-by-step explanation:
Divide total cost by number of units:
$10.48 / 8 rolls = $1.31/roll
1/3 + 1/6
---Find a common denominator, or the least common multiple of the given denominators. In this case, that would be 6.
1/3 = 2/6
1/6 = 1/6
---Now add the fractions
2/6 + 1/6
3/6
---Simplify/Reduce the fraction
3/6
1/2
Answer: 1/2
1/3 + 1/6 = 2/6 + 1/6 = 3/6 (or 1/2)
Hope this helps!
