Question

can some one help me with logs

Answer 1

yeah

Answer 2

Water at 25 degrees Celsius has a pH of 7. Anything that has a pH lower than 7 is called acidic, while a pH above 7 is basic, or alkaline. Seawater has a pH just over 8, while lemonade has a pH of approximately 3.

Answer 3

Create a graph of the pH function. Locate on your graph where the pH value is 0 and where it is 1. You may need to zoom in on your graph.

Answer 4

A pool company forgets to bring their logarithmic charts, but they need to raise the amount of hydronium ions in a pool by 0.50. Using complete sentences, explain how your graph can be used to solve 10–y = 0.50. Find the approximate solution.

Answer 5

\[10^{-y}=0.50\]

Answer 6

0.50=1/2=(2)^-1 Taking logarithms with base 10 er have -ylog(10)=log(2^-1)
This implies -ylog(10)=-log(2) Hence y=log(2)/log(0)=log(2) since log 10=1

Answer 7

log 2/log(10)

Answer 8

wait ok can u explain that in a different way im am really confused

Answer 9

log(a^b)=blog(a) i used this formula

Answer 10

^ means raised to the power

Answer 11

okay thank you i get it now
