Answer: On the Northern horizon
Explanation:
If the star is directly overhead when you stand at the North Pole, it will sink further and further the more you move south towards the equator due to the earth's curve. When you get to the equator, the star will ideally sit right on the northern horizon.
After one crosses the equator however, the star will disappear from view. It is therefore not possible to see this star from anywhere south of the Equator to the South Pole.
Answer:
I think it's C, but I'm not 100% sure
Answer:
a(I).Q4, (ii). W3.
(b). Q4.
(c). (i) and (ii). Check Explanation
Explanation:
Note: Kindly check the attachment for the graph. The solution to the question is given below;
(a). Using the labels from the graph above, identify each of the following.
(i) The optimal quantity of labor Larry’s Lumber Mill will hire will be at a point in which marginal cost = marginal revenue which is point Q4
(ii). The wage rate Larry’s Lumber Mill will pay is at a point in which the Marginal revenue = marginal cost that is at point W3.
(b). Using the labels from the graph above, the number of workers Larry’s Lumber Mill would hire if the labor market were perfectly competitive is Q4.
(c). (i). Larry’s Lumber Mill’s demand for labor increase which will cause a shift to the right on the demand curve. This is so, because as the demand for housing increases, the demand for lumber will increase too.
(ii). The supply is lesser than the demand which will cause a shift to the left on the supply curve.
