In △ ABC, there is an inscribed rectangle EFGH.AD Is the height on the edge of BC, BC = 10, ad = 8, rectangular area s, ad and EF intersect with K
(1) When AK, s > 10?
(2) When AK is large, s is the largest?

Let AK length x, rectangle length (bottom edge) a, width b (height)
Then B = 8-x
△AEF∽△ABC
a/10=x/8
a=5x/4
S=ab=(8-x)*5x/4=10x-5x²/4
1、S=10
That is, 10x-5x & # / 4 = 10
X = 4 + 2 √ 2 or x = 4-2 √ 2
2、
S=10x-5x²/4
=-5/4*(x²-8x)
=-5/4*(x²-8x+16-16)
=20-(x-4)²
When x = 4, Smax = 20

If the quadratic equation AX ^ 2 + BX + C = 0 has two x1, X2, then we can make X1 > 0, X2 > 0 if and only if?
The answer is B ^ 2-4ac > = 0 and - B / a > 2 and (a + B + C) / a > 0, where (a + B + C) / a > 0, how can we get it?

Wrong?
-B / a > 2 is too strong
To the contrary:
Let f (x) = ax ^ 2 + BX + C
So f '(x) = 2aX + B
Deform - B / a > 2
There is 2A + B

In △ ABC, the length of its three sides is a, B, C, and (B + C): (c + a): (a + b) = 4:5:6, then the maximum internal angle of the triangle is______ ．

From (B + C): (c + a): (a + b) = 4:5:6, if B + C = 8, ∧ C + a = 10, a + B = 12, ∧ a = 7, B = 5, C = 3, from cosine theorem, we can get 49 = 25 + 9-30cosa, ∧ cosa = - 12, ∧ a = 120 ° and the maximum internal angle of a triangle is 120 °. So the answer is: 120 °

How to flow the current of sliding rheostat by partial crimping method?

As shown in the figure, the current starts from the positive pole and flows to the B end, passes through the resistance of BP section, and when it flows to the P position, it begins to split, some of which returns to the negative pole through R, and some of which returns to the negative pole through the resistance of PA section
