1)Suppose u={1, 2, 3, 4, 5,}is the universal set and r ={...,-3, -1, 1, 3,...} Whats's R??
2)Suppose u= {...,-3, -2, -1, 0, 1, 2, 3,...} is the universal set and
R={...,-3, -1, 1, 3,...} What's R??
They are two questions can someone help me Plz? i can't seem to understand them.
Ms.Sue can you help?
no idea. what does R have to do with u and r? Is R=r' ? If so, then
#1: R = r' = u-r = {2,4,6,...}
#2 u-r = {...-4,-2,0,2,4,...}
no wait am so sorry i meant to put a A not RR in the first one not r but a
I can help you understand the questions. Let's break them down step by step:
1) In this question, the universal set u is defined as {1, 2, 3, 4, 5}. The set r is defined as {..., -3, -1, 1, 3, ...}.
To understand what R is, we need to identify the elements in r that also belong to the universal set u. From the given definitions, we see that -3, -1, 1, and 3 are all elements of r. Out of these, only 1 and 3 also belong to the universal set u. Therefore, R can be defined as the set {1, 3}.
2) In this question, the universal set u is defined as {..., -3, -2, -1, 0, 1, 2, 3, ...}. The set R is defined as {..., -3, -1, 1, 3, ...}.
Similar to the previous question, we need to identify the elements in R that also belong to the universal set u. From the given definitions, we see that -3, -1, 1, and 3 are all elements of R. Out of these, all four elements also belong to the universal set u.
Therefore, R in this case is equal to the set {..., -3, -1, 1, 3, ...}, since all of its elements belong to the universal set u.
I hope this helps! Let me know if you have any further questions.
I'd be happy to help you understand these questions! Let's break them down one by one.
Question 1:
Suppose u = {1, 2, 3, 4, 5} is the universal set and r = {..., -3, -1, 1, 3, ...}. The question is asking for the set R.
To understand R, we need to look at the pattern in the set r. By looking at the given elements, we can see that it alternates between -3 and 1, with a difference of 2 between each element. The pattern continues indefinitely in both directions.
Using this pattern, we can write the set R as R = {..., -3, -1, 1, 3, ...}, which means that R is the set that consists of all the elements in r where each element is either -3 or 1, and each successive element has a difference of 2.
Question 2:
Suppose u = {..., -3, -2, -1, 0, 1, 2, 3, ...} is the universal set, and R = {..., -3, -1, 1, 3, ...}. The question is again asking for the set R.
In this case, the universal set u includes all integers starting from -3 and continuing indefinitely in both directions. The set R is the same as the one in question 1, which is R = {..., -3, -1, 1, 3, ...}. This means that R contains all the elements from u where each element is either -3 or 1, and each successive element has a difference of 2.
I hope this clarifies the questions for you! If you have any further doubts or need more explanation, feel free to ask.
