How long would it take you to double your money is the bank pays 3.6% interest, compounded

Lapatulllka [165]

Answer:

$t=19.25\ years$

Step-by-step explanation:

we know that

The formula to calculate continuously compounded interest is equal to

$A=P(e)^{rt}$

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

e is the mathematical constant number

we have

$t=?\ years\\P=x\\r=3.6\%=3.6/100=0.036\\A=2x$

substitute in the formula above

$2x=x(e)^{0.036t}$

solve for t

simplify

$2=(e)^{0.036t}$

Apply ln both sides

$ln(2)=ln[(e)^{0.036t}]$

Applying property of exponents

$ln(2)=[0.036t]ln(e)$

Remember that ln(e) =1

$ln(2)=[0.036t]$

$t=ln(2)/[0.036]$

$t=19.25\ years$

first get rid of the 5
so X+5-5=18-5
which makes X=13

Find the distance between the two points. Round to the nearest tenth if necessary.

Dafna1 [17]

D = sqrt (x2 - x1)^2 + (y2 - y1)^2
(1,-2)(10.-4)

d = sqrt (10 - 1)^2 + (-4 - (-2)^2
d = sqrt (9^2 + (-4 + 2)^2
d = sqrt (9^2 + (-2^2)
d = sqrt (81 + 4)
d = sqrt 85
d = 9.2
