Segment addition postulate. Trying to help my son figure out how to solve. Given AC=39. A=2x-8, B=x×17. Find X, AB AND BC. We got 25 for X, and 42 for both AB, BC. Its not correct. 42+42 does not equal 39.

Answers

Answer 1

Answer: segment addition postulate says
AB+BC=AC

assuming that A, B, C are in order, and assuming that those are the points,

legnth of AC=|A-C|=39 (|x| means absolute value of x)

A=2x-8
b=17x
AB=|A-B|=|2x-8-17x|=|-8-15x|

we are only given AB but not BC so this is not solvable unless you know BC
AB+BC=AC
BC=AC-AB

BC=39-|-8-15x|
that's as far as I can go since we don't know any more

If an organism had 200 atoms of carbon-14 at death, how many atoms will be present after 14,325 years? Round the answer to the nearest hundredth.

Answers

Answer:

35.34 atoms will be present after 14,325 years.

Step-by-step explanation:

Given : Carbon-14 has a half-life of approximately 5,730 years. This exponential decay can be modeled with the function N(t) = N0. If an organism had 200 atoms of carbon-14 at death.

To find : How many atoms will be present after 14,325 years?

Solution :

The half-life exponential function modeled is $N=N_o((1)/(2))^{(t)/(h)}$

Where, $N_o=200$ is the initial atoms

N is the total number of atoms.

t=14,325 years is the time

h=5,730 years is the half-life time

Substitute the value in the formula,

$N=200((1)/(2))^{(14325)/(5730)}$

$N=200((1)/(2))^(2.5)$

$N=200(0.1767)$

$N=35.34$

Therefore, 35.34 atoms will be present after 14,325 years.
