Will you find the number 89 in the interval 79-89?
Yes, if it is the closed interval. No, if it is the open interval.
Identify the interval -8 3 as open closed half open or unbounded?
Open
Is it possible to take the union of two open intervals and get a closed interval?
No.
Is it possible to take the union of two closed intervals and get an open interval?
aye
What are the example of open interval in math?
An open interval, usually written as (2, 4) is any number between 2 and 4 but excluding the two end points. Another way of writing it is {x : 2 < x < 4}. A closed interval includes both end points and a semi-open or semi-closed includes one but not both.

The interval notation for the interval of real numbers?
There is more than one notation, but the open interval between a and b is often written (a,b) and the closed interval is written [a,b] where a and b are real numbers. Intervals may be half open or half closed as well such as [a,b) or (a,b]. For all real numbers, it is (-infinity,+infinity), bit use the infinity symbol instead (an 8 on its side).
Define intervals on the number scale?
An interval on the number scale is a set of numbers between two end-point. Thus the closed interval [a, b] comprises all number between a and b as well as the two end points. An interval is open if neither end point is included, and semi-open (or semi-closed) if one end in included and the other is not.
Differentiate between open channel flow and pipe flow?
The open channel flow has a free or rather open surface whereas the pipe flow has a closed surface.
Differentiate between open channel flow and pipe flow-?
The open channel flow has a free surface whereas the pipe flow has a closed surface.
Why in rolles theorem closed interval is used for contuinity and open interval is used for differentiability?
It requires that f(a)=f(b) where a and b are beginning and ending points. Also, it says there is a c between a and such that f'(c)=0. If f were not differentiable on the open interval, the statement f'(c)=0 would be invalid.
