Answer:
(-1, 2/3).
Step-by-step explanation:
Taking the derivative of f, we get f' = x^2 - 1 = 0. Thus, x = -1 and x = +1.
At the relative max, y = (1/3)(-1)^3 - (-1) = -1/3 + 1 = 2/3.
The relative maximum is at (-1, 2/3).
It is not periodic. A periodic dataset is a dataset that repeats the same pattern over time.
Answer:
40 items
Step-by-step explanation:
I used the equation 1.5x+50=2.75x to find the answer. If the school were to buy 40 items from either truck, they would both amount to 110.
