The constraints of a problem are listed below. What are the vertices of the feasible region?
Grace [21]
The vertices are the intersections between the lines.

1) line x + y = 5 and y = 3:

y = 3 => x + 3 = 5 => x = 5 - 3 => x = 2

=> vertix = (2,3)

2) line x + y = 5 and y = 0

=> y = 0 => x + 0 = 5 => x = 5

=> vertix = (5,0)

3) line x + y = 5 and x = 0

=> 0 + y = 5 => y = 5

=>  (0,5) ------> this is not a vertix because it is above the line y = 3

4) line y = 3 and x-axis

=> vertix = (0,3)

5) x-axis and y-axis => origin => vertix = (0,0)

So, there are four vertices: (0,0), (5,0), (2,3) and (0,3)

Answer: That is the first option:(<span>0, 0), (0, 3), (2, 3), (5, 0)</span>

                     full price    discounted        total

month 1               49              1                     50

month 2             120             5                    125

month 3              101            24                   125

total                    270           30                  300

                     full price    discounted        total

month 1            0.98           0.02                   1

month 2           0.96           0.04                   1

month 3         0.808          0.192                   1

total              x = 0.9       y = 0.10                 1

x = 270 / 300 = 0.90

y = 30 / 300 = 0.10

<h3>Right angle triangle:</h3>

Right angle triangle have one of its angles as 90 degrees. Therefore, the side a can be found using trigonometric ratios,

Therefore,

tan 47° = opposite / adjacent

tan 47° = a / 570

cross multiply

a = 570 tan 47°

a = 570 × 1.07236871002

a = 611.250164714

a = 611 yards
