Let
F--------------------> future value
P--------------------> present value
r --------------------> interest rate per year
m ------------------ > number of compounding periods per year
t --------------------> time in years.
we know that
P=$1,600
<span>t=17 years
m=2
r=10%------> 0.10
F=P(1+i)</span><span>^n
</span><span>where
i=r/m ---------> 0.10/2=0.05
and
n=m*t------------> 2*17=34
</span>F=1600*(1+0.05)^34=8405.36

Answer:
yes, they are parallel lines in #23
Step-by-step explanation:
the slope of both lines is -1
Let t = number of hours
The first candle starts at 8 inches.
It burns at 7/10 inch per hour, so in t hours it burns (7/10)t inches.
After t hours, its length is 8 - (7/10)t
The second candle starts at 6 inches.
It burns at 1/5 inch per hour, so in t hours it burns (1/5)t inches.
After t hours, its length is 6 - (1/5)t
You want the lengths to be equal, so the equation is
8 - (7/10)t = 6 - (1/5)t
The volume would be <span>15927.87
so
</span>V ≈ 15927.87to be sure with my answer.
