(-3, 5] = {x : -3 < x ≤ 5}
It is (-3, 5].
The interval (-3, infinity).
4.0 × 10-2 written in standard notation is 0.040
To write ( 4 \times 10^{-2} ) in standard notation, you need to move the decimal point two places to the left, since the exponent is negative. This means you convert ( 4 ) into ( 0.04 ). Therefore, ( 4 \times 10^{-2} ) in standard notation is ( 0.04 ).
To write 2100 in decimal, you simply write the number as it is: 2100. In decimal notation, each digit's place value increases by a factor of 10 as you move from right to left, so the first digit from the right represents ones, the second represents tens, the third represents hundreds, and so on. Therefore, the number 2100 in decimal notation has a value of 2 thousands, 1 hundred, and 0 tens and ones.
It is (-3, 5].
The interval (-3, infinity).

Interval notation uses the symbols [ and ( to indicate closed an open intervals. The symbols can be mixed so that an interval can be open on one side and close on the other. Given two real numbers, a, b we can have (a,b) which is the interval notation for all numbers between a and b not including either one. [a,b) all numbers between a and b including a, but not b. (a,b] all numbers between a and b including b, but not a. [a,b] all number between a and b including a and b.
The interval of 0 and 180 refers to the range of values between 0 and 180, inclusive. This interval can be represented in mathematical notation as [0, 180]. It includes all real numbers starting from 0 up to and including 180. This range is commonly used in various contexts, such as angles in geometry, where it represents a half-circle.
The answer to this is 2, and 0.

Interval notation is a method of writing down a set of numbers. An example of this is all numbers that are greater than five.Ê
Why interval, notation cannot be used to represent instead of atomic masses
When a negative notation is used, it typically indicates a value or concept that is less than zero or represents a deficit. In mathematical terms, this can signify a negative number or an operation that results in a decrease. In other contexts, such as programming or logic, it may denote the opposite of a given condition or state. Overall, negative notation conveys a sense of reduction, absence, or inversion.
Sets can be written in various ways, including roster notation, set-builder notation, and interval notation. Roster notation lists all the elements of a set, such as ( A = {1, 2, 3} ). Set-builder notation describes the properties of the elements, like ( B = { x \mid x > 0 } ). Interval notation is often used for sets of numbers, such as ( C = (0, 5] ), indicating all numbers greater than 0 and up to 5.
