1 Dear Mr.Brown ,I have decided that I will join the Lions.If I join the team,I guess that I'll become a great soccer player.I love soccer!I will also travel around the world if I become a lion.I dream...

Z = (1 + radical 3I) ^ n when the minimum is___ Z is an integer

n=3
Here z = - 8
As a result of the minimum, you can start from 1
N = 1, z = 1 + radical (3) I
N = 2, z = - 2 + 2 × radical (3) I
N = 3, z = - 8

The third power of X is 27

X = 3 don't know how to ask

Please draw two figures with the circumference of 8 cm on the square paper. How to do this math problem? Volume 1 of grade 3

Draw a square with a side length of 2 cm, and then a rectangle with a length of 3 cm and a width of 1 cm

1. The image of quadratic function passes through (1,0), (- 1, - 4) and (0, - 3) to find the analytic expression of quadratic function
2. It is known that the quadratic function y = ax & # 178; + BX + C. when x ＞ 1, y increases with the increase of X, and when x ＜ 1, y decreases with the increase of X. through (0,3) (3,6), the analytic expression of the quadratic function is obtained
3. It is known that the image of quadratic function intersects with X-axis at two points (- 1,0) (3,0) and passes through points (1, - 5) to find its analytical formula

1. Let y = ax & # 178; + BX + C pass through (0, - 3), so C = - 3A + B-3 = 0a-b-3 = - 42a = 6 + 4A = 55 + B-3 = 0b = - 2, so the analytic expression of this process is y = 5x & # 178; - 2x-32. Let y = ax & # 178; + BX + C pass through (1,0), so C = 3 and x = 1

If 9x2 + MXY + 16y2 is a complete square, then M=______ ．

∵ (3x ± 4Y) 2 = 9x2 ± 24xy + 16y2, ∵ in 9x2 + MXY + 16y2, M = ± 24

The circumference of the rectangle is 18 cm, and the area is 20 square cm. Find the length and width of the rectangle
Let the length of a rectangle be x cm, and the countable equation is

Let the length of the rectangle be x cm, the width be 18 / 2-x = 9-x cm
X(9-X)=20,
X²-9X+20=0
(X-4)(X-5)=0,
X1=4,9-X=5,
X2=5,9-X=4,
Generally, length > width, so the length of a rectangle is 5cm and the width is 4cm

The inverse scale function y = (1-2m) x ^ m ^ 2-2 in each quadrant where the image is located, y decreases with the increase of X: (1) find the value of M; (2) if the function image
② If the function image passes through (x1, Y1) (X2, Y2), and x1

(1) Topic meaning
1-2m > 0 and M & # 178; - 2 = - 1
∴m=-1
(2) ∵ in each quadrant, y decreases with the increase of X, x1
