What is the future value of $1,600 in 17 years assuming an interest rate of 10 percent compounded semiannually?
Naddika [18.5K]
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
<span>
the answer is $</span>8405.36<span>

How would I start to solve number 15? Would I use distributive property?
natita [175]
-5-x=2x-(4x+6)

Using the distributive property is the correct first step. (4x+6) is being multiplied by -1, so distributing gives

-5-x=2x+(-4x-6)
-5-x=2x+((-4x)+(-6))

Now, using the associative property of addition, you get

-5-x=(2x+(-4x))+(-6)
-5-x=(2x-4x)-6

Simplify the right hand side:

-5-x=-2x-6

Add 5 and 2x to both sides.

(2x+5)-5-x=(2x+5)-2x-6

On the left side, use the associative property. On the right, commutativity and associativity:

2x+(5-5)-x=5+(2x-2x)-6

Simplify.

2x-x=-1
x=-1

I need an equation that has variables on both sides were x = 17
Andrei [34K]

3 (3 + x) = 5x - 25

9 + 3x = 5x - 25

Add 25 to each side

34 + 3x = 5x

Subtract 3x from each side

34 = 2x

Divide each side by 2

17 = x
