Answer:
Africans were deemed suitable for work in the Americas because they were unfamiliar with the land and so less likely to escape, largely resistant to European diseases, accustomed to laboring in the tropics, and came from farming cultures.
Explanation:
Answer:
The turns of a graph is represented by the number of maximum or minimum that the function has.
If we differenciate f(x) we get:
f'(x)=4x^3+6x
f'(x)=2x(2x^2 + 3)
Therefore f'(x) =0, when x=0. Given that negative roots are not defined.
Therefore, the number of turns will be given by the number of solutions of f'(x) which is 1.
Attached you find the graph of the function which confirms the number of turns.
If the function had other solutions, the maximum number of turns it could have is 3! because f'(x) is a third degree polynomial, therefore it can't have more than 3 solutions!
I believe the answer would be opportunity cost. the opportunity cost is the cost to create an item which can result an increase in the price to ensure they make profit
