adiocarbon dating of blackened grains from the site of ancient Jericho provides a date of 1315 BC ± 13 years for the fall of the

Zigmanuir [339]

Answer:

$\left(\frac{m(t)}{m_{o}} \right)_{min} \approx 0.659$ and $\left(\frac{m(t)}{m_{o}} \right)_{max} \approx 0.661$

Step-by-step explanation:

The equation of the isotope decay is:

$\frac{m(t)}{m_{o}} = e^{-\frac{t}{\tau} }$

14-Carbon has a half-life of 5568 years, the time constant of the isotope is:

$\tau = \frac{5568\,years}{\ln 2}$

$\tau \approx 8032.926\,years$

The decay time is:

$t = 1315\,years + 2007\,years \pm 13\,years$ (There is no a year 0 in chronology).

$t = 3335 \pm 13\,years$

Lastly, the relative amount is estimated by direct substitution:

$\frac{m(t)}{m_{o}} = e^{-\frac{3335\,years}{8032.926\,years} }\cdot e^{\mp\frac{13\,years}{8032.926\,years} }$

$\left(\frac{m(t)}{m_{o}} \right)_{min} = e^{-\frac{3335\,years}{8032.926\,years} }\cdot e^{-\frac{13\,years}{8032.926\,years} }$

$\left(\frac{m(t)}{m_{o}} \right)_{min} \approx 0.659$

$\left(\frac{m(t)}{m_{o}} \right)_{max} = e^{-\frac{3335\,years}{8032.926\,years} }\cdot e^{\frac{13\,years}{8032.926\,years} }$

$\left(\frac{m(t)}{m_{o}} \right)_{max} \approx 0.661$

Answer question in image attached :) 20 points ! I think it is 2/4 just not 100% sure :/

sergiy2304 [10]

Answer:

$\sf \dfrac{BC}{BD} = \dfrac{2}{4}$

Explanation:

BD distance is 4 units

BC distance is 2 units

so in fractions:

$\sf \dfrac{BC}{BD} = \dfrac{2}{4}$

$\sf \dfrac{BC}{BD} = \dfrac{1}{2}$

What is 0.81818182 as a fraction

tia_tia [17]

Answer: $\frac{9}{11}$ .

Step-by-step explanation: The given decimal is 0.81818182, which is recurring and non-terminating decimal form.

Let us consider that

$x=0.81818182\\\Rightarrow 100x=81.818182\\\Rightarrow100x=81+.81818182\\\Rightarrow100x=81+x\\\Rightarrow 100x-x=81\\\Rightarrow99x=81\\\Rightarrow x=\dfrac{81}{99}\\\Rightarrowx=\dfrac{9}{11}$ .

Thus, the fractional form of the decimal 0.81818182 is 9/11.
