1. Fill in the blanks: (This topic is entitled * * 14 small questions, with 5 points for each small question and 70 points for * *) www.ks5u.com

1. If set, then.

2. If the complex number is), then.

3. If the proposition ""is false, the range of real numbers is.

4. Give the following four propositions in space: ① There are two points outside the plane, and one and only one plane is perpendicular to the plane; (2) If there is no * * * line in the plane and the distance from three points to the plane is equal, then; (3) If the straight line is perpendicular to countless straight lines on the plane, then; ④ The projection of two straight lines from different planes on the same plane must be two parallel lines; So the number of correct propositions is.

5. In, yes.

6. The straight line intersects the coordinate axis at point A and point B, and point P moves randomly on line segment AB, so the probability that point P falls in the circle is.

7. It is known that the zero point of the function,, is, and the order from small to large is w.w.w.k.s.5.u.c.o.m

8. The maximum value of the function on the interval is

9. If the function is known, the range of real numbers is.

10. As shown in the figure, the moving point M is on the circle, which is a certain point, then

The maximum value of is.

1 1. Given that the center, right focus and right vertex of an ellipse are O, F and A respectively, and the intersection of the right directrix and the X axis is H, the maximum value of is.

12. A point is a moving point in a square with a side length of 2 or on the boundary, and it is the midpoint of the side, so the maximum value of is.

13. It is known that every item of a series is 1 or 2, the first item is 1, and there is a 2 between 1 and 1, which is the sum of the first 2009 items of the series.

14. The following statements about the curve: ① symmetry about the origin; ② Symmetry of straight lines; ③ is a closed figure with an area larger than; (4) It is not a closed figure and has nothing in common with a circle; ⑤ Four intersections with curve D: exactly the four vertices of the square, and the correct serial number is there.
