Answer:
0
Step-by-step explanation:
The + on the zero means the limit as x approaches 0 from the right side
![\lim_{x \to 0^{+} } (\frac{1}{x} - \frac{1}{|x|})\\ \lim_{x \to 0^{+} } (\frac{1}{x} - \frac{1}{x})\\ \lim_{x \to 0^{+} } (0)\\0](https://tex.z-dn.net/?f=%5Clim_%7Bx%20%5Cto%200%5E%7B%2B%7D%20%7D%20%28%5Cfrac%7B1%7D%7Bx%7D%20-%20%5Cfrac%7B1%7D%7B%7Cx%7C%7D%29%5C%5C%20%5Clim_%7Bx%20%5Cto%200%5E%7B%2B%7D%20%7D%20%28%5Cfrac%7B1%7D%7Bx%7D%20-%20%5Cfrac%7B1%7D%7Bx%7D%29%5C%5C%20%5Clim_%7Bx%20%5Cto%200%5E%7B%2B%7D%20%7D%20%280%29%5C%5C0)
I KNOW THA WEY but wut are you saying the mean price
I'm really sorry, but I only know the first question.
The answer is 340.
Answer:
![3 + \dfrac{2}{log_{10}2}](https://tex.z-dn.net/?f=3%20%2B%20%5Cdfrac%7B2%7D%7Blog_%7B10%7D2%7D)
Step-by-step explanation:
given,
log₂ (800)
using logarithmic identity
logₐ a = 1
logₐ x³ = 3 logₐ x
log (ab) = log a + log b
logₐ x = ![\dfrac{1}{log_x a}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7Blog_x%20a%7D)
now,
log₂ (800)
log₂ (2³ × 100 )
log₂ (2³) + log₂ (100)
3 log₂ (2) + log₂ (10²)
3 + 2 log₂ (10)
![3 + \dfrac{2}{log_{10}2}](https://tex.z-dn.net/?f=3%20%2B%20%5Cdfrac%7B2%7D%7Blog_%7B10%7D2%7D)
I'm estimating that this is about the 5th or 6th time that I've seen this
question posted on Brainly, and there's STILL not enough information
given to answer it. Maybe several different classes in several different
schools are all using the same textbook, and the book has a big mistake
in (at least) one of the problems.
