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
