• The feasible region is defined by 0 < w < √1000 and length = 2w.

• The feasible region is defined by 0 < w < 500 and length = 3w.

• The feasible region is defined by w > 0 and length = w.

• The area of the field must be greater than 2000 square meters.

A company produces two types of products, A and B. The profit from product A is $5 per unit, and from product B is $8 per unit. The production constraints are given by the inequalities x^2 + y^2 ≤ 100 and x + 2y ≤ 40. Graph the system and determine the maximum profit region.

• Maximum profit is $50 at (10, 0).

• Maximum profit is $30 at (5, 10).

• Maximum profit is $40 at (8, 8).

• Maximum profit is $64 at (0, 20).

A park is designed in the shape of a circular area with a radius of 10 meters. There is also a rectangular area adjacent to it where the length is 3 meters longer than the width. If the total area of both sections must be less than 400 square meters, graph the inequalities and find the intersection of the feasible regions.

• The feasible region for the width w is approximately 0 < w < 10.5 meters.

• The feasible region for the width w is approximately 10 < w < 15 meters.

• The feasible region for the width w is approximately 0 < w < 20 meters.

• The feasible region for the width w is approximately 0 < w < 5 meters.

A school is planning to organize a sports event. The number of participants in soccer (x) and basketball (y) must satisfy the inequalities x^2 + y ≤ 50 and 2x + y^2 ≤ 100. Graph the system and analyze the intersection points to determine the possible number of participants.

• Maximum participants: 8

• Maximum participants: 15

• Maximum participants: 5

• Maximum participants: 12

A local bakery sells two types of cakes: chocolate and vanilla. The number of chocolate cakes (x) and vanilla cakes (y) must satisfy the inequalities x + 2y ≤ 30 and x^2 + y^2 ≤ 100. Graph the inequalities and find the feasible region for cake production.

• The feasible region is only defined by x + 2y ≤ 30.

• The feasible region is the area where x^2 + y^2 ≤ 100 is satisfied alone.

• The feasible region is the area where x + 2y ≤ 30 and x^2 + y^2 ≤ 100 overlap.

• The feasible region includes all points where x + y ≤ 30.

A car rental company has a fleet of cars that can be rented for a maximum of 50 hours per week. The rental hours for economy cars (x) and luxury cars (y) must satisfy the inequalities x + y ≤ 50 and x^2 + 2y ≤ 100. Graph the system and identify the feasible rental hours.

• The feasible rental hours are only for economy cars.

• The maximum rental hours for luxury cars is 50 hours.

• The feasible rental hours are the points (x, y) that lie outside the overlapping region of the two inequalities.

• The feasible rental hours are the points (x, y) that lie within the overlapping region of the two inequalities.

• 50 vegetarian meals and 10 non-vegetarian meals.

• 30 vegetarian meals and 20 non-vegetarian meals.

• 10 vegetarian meals and 30 non-vegetarian meals.

A tech company is developing two software products. The development time for product A (x) and product B (y) must satisfy the inequalities x + 3y ≤ 60 and 2x^2 + y ≤ 100. Graph the system and determine the feasible development time for both products.

• The development time for both products is unlimited.
