A person invests 9000 dollars in a bank. The bank pays 6% interest compounded monthly. To the nearest tenth of a year, how long
il63 [147K]

Answer:

7.4\ years  

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=?\ years\\ P=\$9,000\\ r=0.06\\n=12\\ A=\$14,000  

substitute in the formula above  

14,000=9,000(1+\frac{0.06}{12})^{12t}  

(14/9)=(1.005)^{12t}  

Apply log both sides

log(14/9)=(12t)log(1.005)  

t=log(14/9)/[(12)log(1.005)]  

t=7.4\ years

Expression A: 3(x + 2) Expression B: 3x + 6....... Which statement does not show that these expressions are equivalent? O A. Sub
Dovator [93]

Answer:

D. 3(x+2) can be rewritten as 3x + 6 using the distributive property

Step-by-step explanation:

Given

3(x + 2) = 3x + 6

Required

Explain

From the list of given options, option D answers the question.

This is because, the expression above involves distributive property and only option D correctly states that.

A distributive property is:

a*(b + c) = a*b + a * c

In this case:

a = 3  b = x   and c = 2

So:

a*(b + c) = a*b + a * c

Substitute values for a, b and c

3*(x + 2) = 3 * x + 3 * 2

3(x + 2) = 3x + 6
