Answer:
Proved
Step-by-step explanation:
To prove that every point in the open interval (0,1) is an interior point of S
This we can prove by contradiction method.
Let, if possible c be a point in the interval which is not an interior point.
Then c has a neighbourhood which contains atleast one point not in (0,1)
Let d be the point which is in neighbourhood of c but not in S(0,1)
Then the points between c and d would be either in (0,1) or not in (0,1)
If out of all points say d1,d2..... we find that dn is a point which is in (0,1) and dn+1 is not in (0,1) however large n is.
Then we find that dn is a boundary point of S
But since S is an open interval there is no boundary point hence we get a contradiction. Our assumption was wrong.
Every point of S=(0, 1) is an interior point of S.
Answer:
8
Step-by-step explanation:
You need 3 trucks of sand that hold 5 tons and 2 trucks that hold 3 tons to move all the sand in one trip
Answer:
1/3
Step-by-step explanation:
If 6/18 of the cartons are vanilla that means that those are the odds of you picking a vanilla at random
6/18=1/3
Answer:
x = 128
Step-by-step explanation:
ill name the empty angle y for clarification
y + 38 + 90 = 180
y + 128 = 180
y = 52
180 - y = x
180 - 52 = x
x = 128
