Answer 1

И как это решать ? Что делать?

Answer 2

В пятом не уверенна также в четвертом тоже не дописала

Answer 3

It seems like you've provided a list of intervals, each with different notations. These intervals represent sets of real numbers, and the notation used indicates whether the endpoints are included or excluded in the set. Let's clarify each of these intervals:

1. [3,5; 10); This interval includes all real numbers greater than or equal to 3.5 and less than 10. In set notation, it would be written as: [3.5, 10)

2. [0,9; 4,9]; This interval includes all real numbers greater than or equal to 0.9 and less than or equal to 4.9. In set notation, it would be written as: [0.9, 4.9]

3. (101; 105); This interval includes all real numbers greater than 101 and less than 105. In set notation, it would be written as: (101, 105)

4. [0; 5); 942 This interval includes all real numbers greater than or equal to 0 and less than 5. It appears to have an additional value of 942, which is not part of the interval itself.

5. [-5; 2); 2,81 This interval includes all real numbers greater than or equal to -5 and less than 2. It appears to have an additional value of 2.81, which is not part of the interval itself.

6. [-101; 1,2] This interval includes all real numbers greater than or equal to -101 and less than or equal to 1.2. It does not have any additional values.

Please note that intervals are typically represented using square brackets [] for inclusive endpoints and parentheses () for exclusive endpoints. Additional values outside of the specified interval may not be relevant to the interval itself.
