It must be an obtuse triangle
C is the answer because it is
Answer:
option D. 4.7 x 10-4 m
Step-by-step explanation:
<u><em>The correct question is</em></u>
• cell P: 5.0 x 10-4 meters
• cell Q: 3.0 x 10-5 meters
we have
The diameter of cell P is ![5*10^{-4}\ m](https://tex.z-dn.net/?f=5%2A10%5E%7B-4%7D%5C%20m)
The diameter of cell Q is ![3*10^{-5}\ m](https://tex.z-dn.net/?f=3%2A10%5E%7B-5%7D%5C%20m)
Rewrite the diameter of cell P as
![5*10^{-4}\ m=5*10^{-4}(\frac{10}{10})=50*10^{-5}\ m](https://tex.z-dn.net/?f=5%2A10%5E%7B-4%7D%5C%20m%3D5%2A10%5E%7B-4%7D%28%5Cfrac%7B10%7D%7B10%7D%29%3D50%2A10%5E%7B-5%7D%5C%20m)
Find the difference
![50*10^{-5}\ m-3*10^{-5}\ m=47*10^{-5}\ m](https://tex.z-dn.net/?f=50%2A10%5E%7B-5%7D%5C%20m-3%2A10%5E%7B-5%7D%5C%20m%3D47%2A10%5E%7B-5%7D%5C%20m)
Rewrite the difference as
![47*10^{-5}\ m=47*10^{-5}}(\frac{10}{10})=4.7*10^{-4}\ m](https://tex.z-dn.net/?f=47%2A10%5E%7B-5%7D%5C%20m%3D47%2A10%5E%7B-5%7D%7D%28%5Cfrac%7B10%7D%7B10%7D%29%3D4.7%2A10%5E%7B-4%7D%5C%20m)
