A = \(\dfrac{1}{10}\) + \(\dfrac{1}{15}\) + \(\dfrac{1}{21}\) + ... + \(\dfrac{1}{120}\)
A = \(\dfrac{2}{2}\).(\(\dfrac{1}{10}\) + \(\dfrac{1}{15}\) + \(\dfrac{1}{21}\) + ... + \(\dfrac{1}{120}\))
A = \(2\).(\(\dfrac{1}{20}\) + \(\dfrac{1}{30}\) + \(\dfrac{1}{42}\)... + \(\dfrac{1}{240}\))
A = 2.(\(\dfrac{1}{4.5}\) + \(\dfrac{1}{5.6}\) + \(\dfrac{1}{6.7}\) + ... + \(\dfrac{1}{15.16}\))
A = 2.(\(\dfrac{1}{4}\) - \(\dfrac{1}{5}\) + \(\dfrac{1}{5}\) - \(\dfrac{1}{6}\) + \(\dfrac{1}{6}\) - \(\dfrac{1}{7}\) + ... + \(\dfrac{1}{15}\) - \(\dfrac{1}{16}\))
A = 2.(\(\dfrac{1}{4}\) - \(\dfrac{1}{16}\))
A = 2.\(\dfrac{3}{16}\)
A = \(\dfrac{3}{8}\)

\(\dfrac{x+2}{-4}=\dfrac{-9}{x+2}\\ \Rightarrow\left(x+2\right)^2=\left(-4\right)\cdot\left(-9\right)\\ \Rightarrow\left(x+2\right)^2=36\\ \Rightarrow\left(x+2\right)^2=\left(\pm6\right)^2\\ \Rightarrow\left[{}\begin{matrix}x+2=6\\x+2=-6\end{matrix}\right.\\ \Rightarrow\left[{}\begin{matrix}x=4\\x=-8\end{matrix}\right.\)
Vậy, \(x\in\left\{4;-8\right\}.\)
a: Vì OA và OB là hai tia đối nhau
nên O nằm giữa A và B
Ta có: O nằm giữa A và B
OA=OB(=3cm)
Do đó: O là trung điểm của AB
b: Trên tia Oy, ta có: OC<OB
nên C nằm giữa O và B
Để C là trung điểm của OB nên \(OC=\dfrac{OB}{2}\)
=>\(a=\dfrac{3}{2}=1,5\left(cm\right)\)
Robots are becoming more advanced every year, and in the future, they will be able to do many amazing things that can help us in our daily lives.
One of the most exciting things about future robots is that they will be able to help us around the house. Imagine having a robot that can clean your room, wash the dishes, and even cook meals for you! This means you will have more time to play, study, or hang out with friends.
Robots will also help in schools. They can be teaching assistants, helping students with their homework and explaining difficult subjects. This will make learning more interactive and fun. Robots can even help teachers by grading papers and organizing lessons, allowing teachers more time to focus on teaching.
In hospitals, robots will play a big role too. They will help doctors perform surgeries with high precision and care for patients, especially in dangerous situations where humans might be at risk.
Robots will also be important in exploring places where humans can't easily go, like deep under the sea, outer space, or even other planets. These exploration robots can send back important information and help scientists learn more about these mysterious places.
Moreover, robots will be used more in building and construction. They can work faster and make fewer mistakes than humans, which can help build homes and roads more efficiently.
In summary, the future of robots is very exciting. They will not only make our lives easier by doing chores and helping in schools and hospitals but also explore new frontiers and assist in building a better world.
