2011皖南八校二联文科数学参考答案 The second round of the 2011 high school entrance exam in southern anhui university The liberal arts mathematics reference answer C: 2. A resolution: 3 D resolution: available B: 5. B Analysis: s = 2, I = 2; S = 6, I = 3; S = 24, I = 4; S = 120, I = 5; The output I is 5 6. C 7. D resolution: 8. C Resolution: B, because the function has a maximum value and a minimum, so there are two distinct real roots, so the discriminant, the solution or 10. C if alpha, beta, change to line a, b, the proposition as a ∥ b, and a gamma gamma coming b coming this proposition is true proposition; If alpha and gamma for straight line a, b, the proposition as a ∥ beta, and a coming b b coming beta this proposition is false proposition; If beta, gamma for straight line a, b, the proposition as a ∥ alpha and alpha b a coming coming beta this is a true proposition proposition 11. 37 The group is 5, (8-3) * 5 + 12 = 37. 12. Analytic: to make the feasible region, the optimal solution is the optimal solution Check online: /ad/click/? Id = 86 Check online: /ad/click/? Id = 18 13. Resolution: the distance from the center to the line 14 If you shift the image of the function to the right by the length of the unit, the image of the function overlaps with the image of the function, so (), because, so 15. Resolution: 16. (1) (4) (6) (2) Make... (8) Make (10) (12 points) 17. Resolution: (1) proof: The midpoint, the connection, the yi plane again (4) (2)... (9) (12 points) 18. Resolution: (1) (x, y) is a basic events, are two draw CARDS of all basic events (1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6), (2, 1), (2, 2),... (6, 5), 36. (2 points) Expressed in A event , namely, it contains the basic event A has (1, 1), (3, 2), (5, 3), A total of three, (6) (2) in 36 (1) the basic event, meet the event has (3, 1), (4, 1), (5, 1), (6, 1), (5, 2), (6, 2), a total of 6 (10) Therefore, P (B) = (12 points) 19. (1) at the time, the order was made So the function of the monotone increas
