Answer:
1.4
Step-by-step explanation:
10 decreased by 1.4 is 18.6
Answer: 1
-----------------------------------------------------
Explanation:
Replace every copy of x with -1. Then use PEMDAS to simplify
F(x) = -x^3 - x^2 + 1
F(-1) = -(-1)^3 - (-1)^2 + 1 ... every x has been replaced with -1
F(-1) = -(-1) - 1 + 1
F(-1) = 1 - 1 + 1
F(-1) = 0 + 1
F(-1) = 1
Answer:
434,470 gallons
Step-by-step explanation:
The exponential equation for the volume v remaining after t hours can be written as ...
v(t) = (initial amount)×(decay factor)^(t/(decay time))
v(t) = 500,000×(1 -10%)^(t/3)
Then after 4 hours, the remaining volume is ...
v(4) = 500,000×(0.90^(4/3)) ≈ 434,470 . . . . gallons

<em>Comment on the form of the equation</em>
The decay factor is related to the decay rate by ...
decay factor = 1 - (decay rate)
and the decay time is the time applicable to that decay rate. Here, the rate is 10% every 3 hours, so the decay time is 3 hours for a decay rate of 10%.
Answer:
A
Step-by-step explanation:
This is the answer because for example the first number for x=3 and y= 5. So add 3+2=5. If you add 2 to x, you equal y.
