24 nickels
2 quarters
3 dimes
Step-by-step explanation:
(f+g)(x) means we just add the 2 functions, so we have
(x-3) + 2x² = 2x² + x - 3
(f-g)(x) means we subtract g(x) from f(x), so we have
(x-3) - (2x²) = -2x²+x-3
Assuming that the dot signifies a multiplication sign and not a composition sign, we have
(f*g)(x) = f(x) * g(x)
= (x-3) * 2x²
= 2x³ - 6x²
Plugging -2 in, we get
2(-2)³-6(-2)² = -16 -24 = -40
Yes, 5 goes into 100 exactly 20 times because 5 multiplied by 20 is 100
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:
d. 1/4
Step-by-step explanation:
The common ratio will be the ratio of any two adjacent terms:
(3/12)/(3/3) = (1/4)/1 = 1/4
