$3000 is invested in an account at interest rate r, compounded continuously. Find the time required for the amount to triple. (A

arsen [322]

Answer:

$36.62\ years$

Step-by-step explanation:

The value of r is the question is

r=0.03

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

$t=?\ years\\ P=\$3,000\\A=\$9,000\\r=0.03$

substitute in the formula above

$9,000=3,000(e)^{0.03t}$

solve for t

$3=(e)^{0.03t}$

Apply ln both sides

$ln(3)=ln[(e)^{0.03t}]$

Apply property of logarithms

$ln(3)=(0.03t)ln[(e)]$

Remember that

$ln(e)=1$

$ln(3)=(0.03t)$

$t=ln(3)/(0.03)=36.62\ years$

Find the value [[23]] (step functions) helpp pls im so confused if you could also explain it :3

melamori03 [73]

I assume [[x]] stands for "the largest integer smaller than or equal to x".

If x is already an integer, then x itself satisfies the definition. 23 is an integer that is equal to 23. So [[23]] = 23.
