This is exponential decay of the form:
f=ir^t, f=final value, i=initial value, r=rate, t=time in this case:
V(t)=408000((100-18)/100)^t
V(t)=408000(0.82)^t so
Vo=408000 and b=0.82
....
V(8)=408000(0.82)^8
V(8)=$83400.95 to nearest cent
Just search it up. Have a nice day :)
For this case we have the following polynomials:

To divide the polynomials we must follow the following steps:
1) Same base, the exponents are added.
2) Only terms that have the same exponent can be added or subtracted.
3) If the remainder is zero, the division is exact.
Answer:
Note: see attached image for the solution.
Triangle P isn't unique because all sides are equal and all interior angles are equal.
Step 1:
For a number, let us use n.
We know the equation equals 54, and we also know that 54 is sixteen less than n. Thus, we can make the equation:

Step 2:
Now, to solve the equation, we simply have to get the integers to one side. To do this, add 16 to both sides of the equal sign. Our answer is:

Hope this helps.
