Given quadrilateral ABCD. M, N are the midpoints of BC, AD. Set: AC=x, BD=y, MN=z, and \(p=\frac{x+y+2z}{2}\). Prove that: \(S_{ABCD}=\sqrt{p\left(p-x\right)\left(p-y\right)\left(p-2z\right)}\)
1. Find x, given that:
\(\left(x+\frac{1}{3}\right)+\left(x+\frac{3}{40}\right)+\left(x+\frac{3}{88}\right)=\frac{31}{22}\)
2. The arithmatic average of three numbers is equal to 13.5 . The average of the first number and second number is 13, and the average of the second number and third number is 13.85 . Find the three numbers.
3. Compare A and B, given that:
A = 2.015 x 201.7
B = 20.16 x 20.16
\(C=\left\{x\in R,\right\}x< 4\)\(A=\left\{x\in R,\right\}-2\le x< 5\)\(B=\left\{x\in R,\left|x\right|\le3\right\}\) Câu a : viết dưới dạng đoạn, khoảng, nửa khoảng. Câu b: xác định vào biểu diễn trên trục số : \(A\cap B,A\cup B,A\backslash\left(B\cap C\right),C_R\left(A\cup B\right)\)

Những người thuận tay trái là những người khác biệt. Chắc chắn, những người thuận tay trái chiếm khoảng 10% dân số - nhưng, thẳng thắn mà nói, có vẻ như xã hội đã quên về họ. Chỉ cần xem xét tất cả các tiện ích dành cho thuận tay phải, thiết kế khó xử của bàn, và các dụng cụ nấu ăn chỉ phù hợp với tay phải của bạn. Điều gì làm cho một người trở thành một người thuận tay trái? Các nhà khoa học không chắc chắn, nhưng các nghiên cứu chỉ ra một sự tương tác phức tạp giữa gen và môi trường. Mặc dù không tìm thấy chính xác các "gen của người thuận tay trái", nhưng những người thường sử dụng tay trái hơn lại có nhiều thành viên trong gia đình thuận tay trái hơn. Và các nhà nghiên cứu đã tìm thấy các dây thần kinh khác nhau ở cánh tay phải và trái. Tuy nhiên, bất kể điều gì thúc đẩy con người sử dụng bàn tay đối diện, khoa học cũng đã khám phá ra một đặc điểm cá tính đặc biệt mà người thuận tay trái có xu hướng có. Vì vậy, đối với tất cả các bạn thuận tay trái, những người thích dùng tay trái, và những người thuận cả hai tay - đây là lúc để nâng cao kiến thức về thuận tay trái và giúp chấm dứt sự phân biệt đối xử với người thuận tay trái một lần và mãi mãi
