Answer:
6
Step-by-step explanation:
x=6
ax+bx=cx
10+bx=16
10+6=16
x=6
7n + 3 = 3n + 27
7n -3n =27-3
4n =24
n= 6.
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
