Answer:
=3
Step-by-step explanation:
We make the composition of both functions:
f (x) = x ^ 2-1
g (x) = 2x-3
Then:
f (g (x)) = (2x-3) ^ 2-1
Rewriting:
f (g (x)) = 4x ^ 2-12x + 8
The domain of this function is all real numbers.
Equivalently
x: (-inf, inf)
answer:
x: (-inf, inf)
option 1.
Well the constant is 3.50, 5 is how many bracelets, b is the cost of the bracelet, and 13 is the cost. So 5b+3.50<13
Answer:
1, 2 and 5 all know each other.
Step-by-step explanation:
I will denote the people by numbers: 1 2 3 4 5 6 7 8 9
The following information is given in the question.
1 knows two others
2 knows five others
3 knows five others
4 knows six others
5 knows six others
Let's assume the worst case: They all know different persons, so it is difficult to find three people who all know each other.
1 knows 2 and 5
2 knows 1 3 4 5 6
3 knows 9 8 7 6 2
By now, 2, 5 and 6 are known to two people, and others are known to just one person.
4 knows 9 8 7 6 5 3
5 knows 1 2 4 7 8 9
As a result 1, 2 and 5 all know each other.
1 knows 2 and 5
2 knows 1 and 5
5 knows 1 and 2
The reason for this is that there are three groups:
1, (2,3) and (4,5)
As much as we try to separate the people that they know there are nine different persons and at least three of them will be spread to these groups in common.
Answer: Sarah will pay $20966 after 6 years
Step-by-step explanation: 4.7% of 22000 is 1034
1034-22000= $20966
