What is the domain of y equals ln x?
In elementary mathematics, any subset of R+, the non-negative real numbers.
Completely factor the expression 4q2 27r4?
2 x 2 x q x q x 3 x 3 x 3 x r x r x r x r
What is a universal subset?
The universal subset is the empty set. It is a subset of all sets.
What are the subset of -2.324?
A number does not have a subset.
How do you find the are of a cylinder?
surface area=2 x pi x r² + 2 x pi x r x h volume = pi x r² x h
What is the domain of y equals ln x?
In elementary mathematics, any subset of R+, the non-negative real numbers.
If a set A is equivalent to a subset of B and B is equivalent to a subset of A then show that A is equivalent to B?
This problem can be modeled and tested quite easily. Set A can be [X,Y], subset B [X,Y], and subset A [X,Y]. Therefore A and B are equivalent.
Is x subset of f?
It depends on what x and f are.
What is the domain of x squared plus 5x-20?
-15
What is the proper subset?
The set X is a proper subset of Y if Xcontains none or more elements from Y and there is at least one element of Y that is not in X.
Prove that A intersect with B is the subset of A?
Let x be in A intersect B. Then x is in A and x is in B. Then x is in A.
In R with discrete metric space what is open set?
any interval subset of R is open and closed
What wave has xrays?
Electromagnetic waves have x-rays as a subset of their range.
Different kinds of subset in algebra?
Π R.l (R) ⊆ Π S.l (S)
Is z a subset of x?
It depends on what z and x are. Since you did not share that information, it is not possible to give a sensible answer.
Is a vertical line a relation in math?
Yes, you can consider it a relation between the points on the x-axis, and the points on the y-axis. In fact, ANY subset of R squared (in other words, any subset of the points on a plane), including the empty set, sets that contain single points, and larger sets, can be considered a relation in R squared (i.e., two sets of real numbers).
Prove AnB subset A subset AUB?
I shall answer this under the assumption that 'n' means intersection. Recall the definitions of intersection and union: 1) x is an element of AnB if and only if x is an element of A and x is an element of B 2) x is an element of AUB if and only if x is an element of A or x is an element of B and recall that 3) X is an (improper) subset of Y if and only if every element of X is an element of Y Thus, if x is an element of AnB, then x is an element of A and an element of B, so it clearly is an element A (law of simplification in logic). This implies AnB is a subset of A. Now if x is an element of A, it is certainly an element of A or an element of B (law of addition in logic), and therefore x is an element of AUB. There are other ways of answering this based on axiomatic approaches.
