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

Hello:
<span>cube root 64(cos330+isin330) iz the complex number with :
z^3 =</span><span> 64(cos330+isin330) ...(1)
let: z = r(cos(</span>θ) +isin(<span>θ))
so : z^3 = r^3 (</span>cos(3θ) +isin(3θ))...(2) ( by moivre)
by(1) and (2) :
r^3 =64 = 4^3 and 3θ =11π/6 +2k<span>π.... k=0 , 1 , 2
</span>r =4 and θ = 11π/18 +2kπ/3 ..... k=0 , 1 , 2
coclusion : 3 <span>cube root ....calculate if k = 0 , 1 , 2</span>
