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

$log(14/9)=(12t)log(1.005)$

$t=log(14/9)/[(12)log(1.005)]$

$t=7.4\ years$

Answer:

x = 5 ; z = 70

Step-by-step explanation:

Vertical angles have the same degree measure

(13x + 45) = 110

13x + 45 = 110

-45 -45

13x = 65

/13 /13

x = 5

Complementary angles add up to 180°

110 + z = 180

-110 -110

z = 70
