Answer:
- C
- B
- A
- E
- D
Step-by-step explanation:
1. All numbers on either of lists B or C are all the numbers 1..6, as in choice C.
__
2. Numbers in B that are also in A are just 2 and 4. 6 is not in A. choice B.
__
3. Numbers in both A and C are just the numbers in C. choice A.
__
4. There are no numbers in both B and C, so B∩C is the empty set. Anything intersected with the empty set is the empty set. choice E.
__
5. As in (4), but here, we want the union of A with the empty set. That result will be set A, choice D.

Answer:
2.4747996 * 10^1
Step-by-step explanation:
When working in scientific notation, (a * 10^b) * (c*10^d)
Multiply a*c then add 10 ^(b+d)
Then check that the product of ac is between 1 and 10, if not then we need to adjust so that it is
(7.93205×10^8) • (3.12×10^-8)
(7.93205) • (3.12) =24.747996
10^(8-8) = 10^0
24.747996 needs to be adjusted to be between 1 and less than 10
we move the decimal 1 to the left so we add 1 to the exponent
2.4747996 * 10^0+1
2.4747996 * 10^1
