Because of our limited money, time, and effort, we are best off when we allocate things a. by constantly assessing the opportunity costs of our choices. b. by being selfish with our time to benefit society. c. with the objective of maximizing output. d. by choosing what society as a whole would want.

by constantly assessing the opportunity cost of our choices.(A)

Explanation:

Resources allocation has to do with how resources are distributed. Human wants are unlimited and there are limited resources so we have the problem of resource allocation.

The problem of allocation of resources is due to the scarcity of resources, and as a result, people make choices. Choices are made by assessing the wants should be satisfied and the wants that should be left unsatisfied.

Due to the scarcity of resources, we are best off allocating things by assessing the opportunity cost of our choices. We have to look at the impact of what we forgo when we make choices.

b

explanation:

start by isolating the variable on one side by adding 43w^2 to both sides.   the equation will read:

25w^2+5=0

*subtract 5 from both sides*

25w^2=-5

*divide both sides by 25*

w^2=-1/5

*take the square root of both sides*

w=√(-1/5)

the square root of -1 is i.   the square root of 5 remains √5

the answer is i/√5.

hope this
