Answer:
The length between the two points is RT = 1.3 units
Step-by-step explanation:
The coordinates of the point R and T are R(2,1.2) and T(2,2.5).
Now, by DISTANCE FORMULA:
The distance between two coordinates P and Q with coordinate P(a,b) and Q(c,d) is given as:
So, here the distance RT =
or, RT = 1.3 units
Hence, the length between the two points is RT = 1.3 units
Answer:
Step-by-step explanation:
U is the universal set, that is, a set that contains the universe of possible sets, which is formed by 10 elements in this. Q is a subset of U formed by three elements: 3, 6, 9. ()
represents the complement of the complement of
. The complement of
is the subset of
formed by elements not contained in
. which simbolized by
. That is, 1, 2, 4, 5, 7, 8, 10.
The complement of corresponds to the elements contained in
. Hence, the correct answer is
.
