Answer:
2 days
Step-by-step explanation:
Understanding :
- Number of men is inversely proportional to the number of days taken to complete a job
- 6 men take 5 days to complete 1
- Now the number of men is 15
Solving :
- Rate of change of men ∝ 1/Rate of change of days
- 15/6 ∝ 1/(d/5)
- 2.5 = 5/d
- d = 2 days
Answer:
The stock lost $14 in 7 days
Step-by-step explanation: I know how to multiply.
To find f(2), put 2 where the variable is, then do the arithmetic. It might be easier to factor out x^2:
f(x) = (-6x-4)·x^2
f(2) = (-6·2-4)·2^2
= -16·4
= -64
Then the ordered pair (x, f(x)) for x=2 is
B. (2, -64)
Answer:
Step-by-step explanation:
We first have to write the equation for the sequence, then finding the first five terms will be easy. Follow the formatting:
and we are given enough info to fill in:
and
and
or in linear format:
where n is the position of the number in the sequence. We already know the first term is -35.
The second term:
so
and
The third term:
and
so
and we could go on like this forever, but the nice thing about this is when we know the difference all we have to do is add it to each number to get to the next number.
That means that the fourth term will be -27 + 4 which is -23.
The fifth term then will be -23 + 4 which is -19. You can check yourself by filling in a 5 for n in the equation and solving:
and
so
X = 13
Hope that helps (:
