Answer:
here's what I would put:
Explanation:
If i were in this situation, I wouldn't use things such as violence, weapons, etc. I would prepare myself for this kind of situation and take self defense lessons, as to where I could stop the intruder but not hurt them. I would also install a goood security system, like locks and cameras.
The actual answer is the <em><u>corpus callosum</u></em> hope this helps :)
Answer:
The rock is 3.75 billion years ago.
Explanation:
Given that:
Half life = 1.25 billion years
1 billion years = 10⁹ years
So,
Half life = 1.25 × 10⁹ years
![t_{1/2}=\frac {ln\ 2}{k}](https://tex.z-dn.net/?f=t_%7B1%2F2%7D%3D%5Cfrac%20%7Bln%5C%202%7D%7Bk%7D)
Where, k is rate constant
So,
![k=\frac {ln\ 2}{t_{1/2}}](https://tex.z-dn.net/?f=k%3D%5Cfrac%20%7Bln%5C%202%7D%7Bt_%7B1%2F2%7D%7D)
![k=\frac {ln\ 2}{1.25\times 10^9}\ year^{-1}](https://tex.z-dn.net/?f=k%3D%5Cfrac%20%7Bln%5C%202%7D%7B1.25%5Ctimes%2010%5E9%7D%5C%20year%5E%7B-1%7D)
The rate constant, k = 5.5452 × 10⁻¹⁰ years⁻¹
Initial amount [A₀] = 80 micrograms
Final amount
= 10 micrograms
Using integrated rate law for first order kinetics as:
![[A_t]=[A_0]e^{-kt}](https://tex.z-dn.net/?f=%5BA_t%5D%3D%5BA_0%5De%5E%7B-kt%7D)
So,
![10=80\times e^{-5.5452\times 10^{-10}\times t}](https://tex.z-dn.net/?f=10%3D80%5Ctimes%20e%5E%7B-5.5452%5Ctimes%2010%5E%7B-10%7D%5Ctimes%20t%7D)
![80e^{-5.5452\times \:10^{-10}x}=10](https://tex.z-dn.net/?f=80e%5E%7B-5.5452%5Ctimes%20%5C%3A10%5E%7B-10%7Dx%7D%3D10)
![\frac{80e^{-5.5452\times \:10^{-10}x}}{80}=\frac{10}{80}](https://tex.z-dn.net/?f=%5Cfrac%7B80e%5E%7B-5.5452%5Ctimes%20%5C%3A10%5E%7B-10%7Dx%7D%7D%7B80%7D%3D%5Cfrac%7B10%7D%7B80%7D)
![\ln \left(e^{-5.5452\times \:10^{-10}x}\right)=\ln \left(\frac{1}{8}\right)](https://tex.z-dn.net/?f=%5Cln%20%5Cleft%28e%5E%7B-5.5452%5Ctimes%20%5C%3A10%5E%7B-10%7Dx%7D%5Cright%29%3D%5Cln%20%5Cleft%28%5Cfrac%7B1%7D%7B8%7D%5Cright%29)
![x=\frac{10^{10}\times \:3\ln \left(2\right)}{5.5452}=3.75\times 10^9](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B10%5E%7B10%7D%5Ctimes%20%5C%3A3%5Cln%20%5Cleft%282%5Cright%29%7D%7B5.5452%7D%3D3.75%5Ctimes%2010%5E9)
So,
<u>The rock is 3.75 billion years ago.</u>
The right answer is (D) all of the above. Non-verbal communication is carried out through a wide variety of signs: sensory images (visual, auditory, olfactory ...), sounds, gestures, body movements, among others. And in this case the 3 options dads correspond to gestures of body language or kinésticos, sending messages without words (act of nonverbal communication)
