Answer:
A) 3π/4
B) 9π/7
C) 11π/6
Step-by-step explanation:
In the picture attached, the points are shown
Point A is between π/2 radians (90°) and π radians (180°). The only possible option is 3π/4
Point B is between π radians (180°) and 3π/2 radians (270°). The only possible option is 9π/7
Point C is between 3π/2 radians (270°) and 2π radians (360°). The only possible option is 11π/6
Answer:
(0,2.3) if only one choice expected.
(0,2.3) and (0,0) if "all that apply" expected, since (0,0) is also a vertex of the green region.
Step-by-step explanation:
From the attached diagram, the given answer optsions are shown in brown.
The red line shows the optimal combinations of the two variables, hence a maximization problem.
Out of the four answer options, two coincide with a vertice of the valid region (shown in green), namely (0,0) and (0, 2.3).
Out of the two indicated options which correspond to a vertex, the origin (0,0) is usually ignored for a maximization problem, which leaves us with (0,2.3) as the answer.
