A fossil was analyzed and determined to have a carbon-14 level that is 80 % that of living organisms. the half-life of c-14 is 5

liq [111]

Answer:

The fossil is 1860 years old.

Step-by-step explanation:

The equation for the amount of fossil has the following format:

$Q(t) = Q(0)e^{rt}$

In which Q(t) is the amount after t years, Q(0) is the initial amount and r is the rate of change.

Half-life of c-14 is 5730 years.

This means that $Q(5730) = 0.5Q(0)$

So

$Q(t) = Q(0)e^{rt}$

$0.5Q(0) = Q(0)e^{5730r}$

$e^{5730r} = 0.5$

$\ln{e^{5730r}} = \ln{0.5}$

$5730r = \ln{0.5}$

$r = \frac{\ln{0.5}}{5730}$

$r = -0.00012$

So

$Q(t) = Q(0)e^{-0.00012t}$

How old is the fossil?

This is t for which

$Q(t) = 0.8Q(0)$

So

$Q(t) = Q(0)e^{-0.00012t}$

$0.8Q(0) = Q(0)e^{-0.00012t}$

$e^{-0.00012t} = 0.8$

$\ln{e^{-0.00012t}} = \ln{0.8}$

$-0.00012t = \ln{0.8}$

$t = -\frac{\ln{0.8}}{-0.00012}$

$t = 1860$

The fossil is 1860 years old.

1. What is the area of a circle with a diameter of 3.4 cm? Round your answer to the nearest tenth. (use 3.14 for pi)

Brilliant_brown [7]

1. The area of a circle is
$a = \pi {r}^{2}$
$\pi = 3.14 \\ r = \frac{3.4}{2} = 1.7$
$a = (3.14) {(1.7)}^{2} \\ = 9.0746$
The area is 9.07 cm^2.

2. The volume of a cube is
$v = {s}^{3}$
$s = 4.5$
$v = {(4.5)}^{3} \\ = 91.125$
The volume is 91.125 m^3

Answer:

<h2>only x = 39</h2>

Step-by-step explanation:

x + 6 = 45 <em>subtract 6 from both sides</em>

x + 6 - 6 = 45 - 6
