Answer:

Step-by-step explanation:
The fish population after t years can be modeled by the following equation:

In which F(0) is the initial population and r is the constant rate of decay.
Year one the fish population was 18000
This means that 
In year three the fish population was 8000 fish.
Two years later, so 






So

Answer:
486
Step-by-step explanation:
Hello!
To find the surface area of a cube we use the equation

S is the surface area

Answer:
12-24x
Step-by-step explanation:
Answer:
Step-by-step explanation:
point-slope formula is asked for [y-y1 = m(x-x1]
where the given point, P=(x1,y1) = (-4,6)
and the slope , m is given as 3/2
so plug those into the formula
y-6=3/2(x-(-4))
y-6=3/2(x+4)
voila .. you are done :)
