A rectangular iron plate is 10 decimeters long and 8 decimeters wide. Cut the largest circle in this iron plate. How many square decimeters is the area of this circle?
The perimeter of a square and a circle is 12.56 decimeters, so what is their area?

(1) 4 × 4 × 3.14 = 50.24 square decimeter)
(2) Square: 12.56 △ 4 = 3.14 (decimeter)
3.14 × 3.14 = 9.8596 (square decimeter)
Circular: 12.56 △ 3.14 = 4 (decimeter) - diameter
4 △ 2 = 2 (decimeter)
Area: 2 × 2 × 3.14 = 12.56 (square decimeter)

How to convert the weight of fabric meter into that of square meter

The unit of gram weight per square meter is g / m ^ 2 (assumed to be 200), which is the weight of cloth per square meter. As long as the width of cloth W is known, the gram weight per meter can be calculated as 200 * W

5. Calculate the area of shadow in the figure below. (unit: cm)

Subtract the area of the triangle from the area of the semicircle

X÷(1×2)+X÷(2×3)+… +X÷(2007×2008)=2007
How much is x?

x/1*2+x/2*3+x/3*4+...+x/2007*2008=2007
x(1-1/2+1/2-1/3+...+1/2006-1/2007+1/2007-1/2008)=2007
2007x/2008=2007
x=2008

Given that vector a and vector b satisfy vector a = 1, vector b = 2, vector a-vector B = 2, then vector a + vector b=

|A | = 1, | B | = 2, and: | A-B | ^ 2 = (a-b) · (a-b) = | a | ^ 2 + | B | ^ 2-2a · B = 1 + 4-2a · B = 4
So: a · B = 1 / 2, so: | a + B | ^ 2 = (a + b) · (a + b) = | a | ^ 2 + | ^ 2 + 2A · B = 5 + 2A · B
=5 + 1 = 6, that is: | a + B | = sqrt (6)

It is known that in △ ABC, ∠ B = 60 ° AD and CE divide ∠ BAC and ∠ BCA equally

Take a point F on AC such that AF = AE, connect of. It is proved that CF = CD ∵ ad is an angular bisector
The aoo = AOE = AOE = AOE = AOF and AOF, AOE = AOE = AOF, AOE = AOF, AOE = AOF, AOF, AOF, AOF, B = 60 60 \\\\\\\\\\\\\\\\\\\\\\\\\\\\\Δocf (ASA) ∧ CF = CD ∧ AC = AF + CF = AE + CD

The minimum value of function f (x) = 3x + 12x2 (x > 0) is______ ．

∵ x > 0 ∵ 3x + 12x2 = 3x2 + 3x2 + 12x2 ≥ 333x2 · 3x2 · 12x2 = 9 if and only if 3x2 = 12x2, i.e. x = 2, the equal sign holds. Therefore, the minimum value of function f (x) = 3x + 12x2 (x > 0) is 9, so select: 9

A mathematical proof problem (high school)
If the line L: ax + by + C = 0 of point P2 (X2, Y2) and P1 (x1, Y1), P2 line intersects point P, it is proved that the ratio of p1p2 is - (ax1 + by1 + C) / (AX2 + BY2 + C)

It is proved that: P1 (x1, Y1), P (x, y), P2 (X2, Y2) can be set, and the ratio of p1p2 is t (t ≠ - 1), that is, p1p / PP2 = T. = = = > p1p = t * PP2. (here, PP1, PP2 are vectors) = = = > (x-x1, Y-Y1) = t (x2-x, y2-y) = = = = = > x-x1 = t (x2-x), and Y-Y1 = t (y2-y) = = = = > x = (x1 + TX2) / (1
