There are seven bamboo poles in a row. The first one is one meter long, and the other one is half the length of the former one. Q: how many meters is the total length of these seven bamboo poles? (thinking time: 60 seconds)

The total length of the seven bamboo poles is s = 1 + 1 × (12) 1 + 1 × (12) 2 + 1 × (12) 3 + 1 × (12) 4 + 1 × (12) 5 + 1 × (12) 6, = 1 × [1 − (12) 7] 1 − 12, = 2 - (12) 6, = 16364m

Simplification: 81-a & sup2 / A & sup2; + 6A + 9 △ A-9 / 2A + 6 + A + 15 / A + 3

(81-a²)/(a²+6a+9)÷(a-9)/(2a+6)+(a+15)/(a+3)
=(9+a)(9-a)/(a+3)²÷(a-9)/(2a+6)+(a+15)/(a+3)
=-(9+a)(2a+6)/(a+3)²+(a+15)/(a+3)
=(-18a-54-2a²+6a+a²+18a+45)/(a+3)²
=(-a²+6a-9)/(a+3)²
=-(a-3)²/(a+3)²

One side of the triangle is 3cm longer than the second side, and this side is 4cm shorter than the third side. The perimeter of the triangle is 28cm. Find the length of the shortest side

Let the length of the second side be xcm, then the length of the first side is (x + 3) cm and the length of the third side is (x + 7) cm

Given that loga (x2 + 4) + loga (Y2 + 1) = loga5 + loga (2xy-1) (a > 0, and a ≠ 1), the value of log8yx is obtained

It is known that (x2 + 4) (Y2 + 1) = 5 (2xy-1), that is, x2y2 + x2 + 4y2 + 4 = 10xy-5, that is, (x2y2-6xy + 9) + (x2 + 4y2-4xy) = 0, that is, (xy-3) 2 + (x-2y) 2 = 0. Therefore, YX = 12. Log8yx = log812 = -13

To make a 256 liter square bottomless water tank, how much is the side length of the square bottom?

Let the base be x and Y and the height be Z
XYZ = 256 is Z = 256 / XY
Minimum total area required:
opt.min .2(yz+xz)+xy=512(x+y)/xy + xy=512/x + 512/y + xy>=3*512*512
If and only if 512 / x = 512 / y = XY, the minimum value is taken, so x = y = 64

In triangle ABC, ab = 5, AC = 3, BC = 4, PQ is parallel to ab. when the area of s triangle PQC is equal to that of s quadrilateral pabq, the length of PC is obtained

Let p be on the edge of AC,
∵ s △ PQC = s quadrilateral pabq,
That is s △ ABC = s △ PQC + s quadrilateral pabq = 2S △ PQC
∵PQ‖AB,∴△PQC∽△ABC
∴S△PQC/S△ABC=(PC/AC)^2
That is, 1 / 2 = (PC / 3) ^ 2
PC = 3 √ 2 / 2

Through the parabola y = 1 / 4 (x ^ 2), two different points a and B make the tangent of the parabola to intersect at point P, which satisfies the trajectory equation of point P obtained by PA vertical Pb (1);

4Y = (x ^ 2) set point A: (m, 0.25m ^ 2) set tangent y = KX + B of a into m, and then substitute 4Y = x ^ 2, so that the root has only one solution, and the tangent is y = MX / 2-0.25m ^ 2. Point B: (n, 0.25N ^ 2) substitute n, and then substitute 4Y = x ^ 2, so that the tangent of the root has only one solution is y = NX / 2-0.25n ^ 2, and the two lines are vertical, satisfying M / 2 * n / 2 = - 1MN = -
