What rate of interest compounded annually is required to double an investment<br> in 18 ​years?
andreev551 [17]

Answer:

r=3.93\%

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=18\ years\\ P=x\\A=2x\\ r=?\\n=1  

substitute in the formula above

2x=x(1+\frac{r}{1})^{1*18}  

2=(1+r})^{18}  

Elevated both sides to 1/18

2^{\frac{1}{18}} =1+r

r=2^{\frac{1}{18}} -1

r=0.0393

convert to percentage

Multiply by 100

r=3.93\%

For what values of x is the rational expression below undefined?
agasfer [191]
The simplified form is (x+8)/ (x-6)(x+4).

In order for the expression to be undefined, the denominator must be equal to 0. Therefore you can set (x-6)(x+4)=0 so theerefore x=6 and x=-4
