The slope would be:
-5--3/3-1
-2/2
-1
Slope = -1
The population starts at 2000, so a=2000.
We also know that the population in 3 hours is 1000, so we can setup the equation:
2000 b^3 = 1000
This gets us:
b^3 = 1/2
And taking the cube root of both sides gives us:
b ≈ 0.7937005259841
Rounding that to 4 places, we have:
f(t) = 2000 (0.7937)^t
Multiply them together. The product is the answer of a multiplication process.
Answer: 3
Step-by-step explanation:
simply divide 1200 by 400. :)
