Question

PLEASE HELP! THANK YOU!

Answer 1

Answer is 6

------------------------------------------------------------------

Work Shown:

$364 = 900(1-0.14)^t$

$364 = 900(0.86)^t$

$\frac{364}{900} = 0.86^t$

$\frac{91}{225} = 0.86^t$

$\log\left(\frac{91}{225}\right) = \log\left(0.86^t\right)$

$-0.39314112579027 \approx t*\log\left(0.86\right)$

$-0.39314112579027 \approx t*\left(-0.06550154875643\right)$

$\frac{-0.39314112579027}{-0.06550154875643} \approx t$

$6.0020126738099 \approx t$

$t \approx 6.0020126738099$

which rounds to 6 when rounding to the nearest whole number

So it takes roughly 6 years for the value to go from $900 to $364

Answer 2

Answer:

answer is 6

Step-by-step explanation:

Work Shown:

364 = 900(1-0.14)^t

364 = 900(0.86)^t

\frac{364}{900} = 0.86^t

\frac{91}{225} = 0.86^t

\log\left(\frac{91}{225}\right) = \log\left(0.86^t\right)

-0.39314112579027 \approx t*\log\left(0.86\right)

-0.39314112579027 \approx t*\left(-0.06550154875643\right)

\frac{-0.39314112579027}{-0.06550154875643} \approx t

6.0020126738099 \approx t

t \approx 6.0020126738099

which rounds to 6 when rounding to the nearest whole number

So it takes roughly 6 years for the value to go from $900 to $364
