Question

Is my answer right?

Answer 1

If you have ever swum in a pool and your eyes began to sting and turn red, you are aware of the effects on an incorrect pH level. The pH level measures the concentration of hydronium ions and can be modeled by the function p(t) = –log10 t. The variable t represents the amount of hydronium ions, and p(t) gives the resulting pH level.

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

Answer 2

2.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 3

My answer: My graph can be used by using a function with 0.50 as t in the equation p(0.50)=-log10(0.50) then graphing it.

Answer 5

It says to use the graph to solve it. Not try to solve it algebraically. Also, is the equation supposed to be y - 10 = 0.50x ?

Answer 6

Yes about it being y-10=0.50x but I don't have to use the graph just explain how they can use mine.

Answer 8

I don't get it. :(

Answer 9

Would it be y-10=0.50(1)?
