***I will fan and medal. Please Help***
If you ever swam in a pool and your eyes began to sting and turn red, you felt the effects of an incorrect pH level. pH measures the concentration of hydronium ions and can be modeled by the function p(t) = −log10t. The variable t represents the amount of hydronium ions; p(t) gives the resulting pH level.
Water at 25 degrees Celsius has a pH of 7. Anything that has a pH less than 7 is called acidic, a pH above 7 is basic, or alkaline. Seawater has a pH just more than 8, whereas lemonade has a pH of approximately 3.

Best ResponseYou've already chosen the best response.01. Create a graph of the pH function either by hand or using technology. Locate on your graph where the pH value is 0 and where it is 1. You may need to zoom in on your graph.

Best ResponseYou've already chosen the best response.02. The pool maintenance man forgot to bring his logarithmic charts, and he needs to raise the amount of hydronium ions, t, in the pool by 0.50. To do this, he can use the graph you created. Use your graph to find the pH level if the amount of hydronium ions is raised to 0.50. Then, convert the logarithmic function into an exponential function using y for the pH.

Best ResponseYou've already chosen the best response.03. The pool company developed new chemicals that transform the pH scale. Using the pH function p(t) = −log10t as the parent function, explain which transformation results in a yintercept and why. You may graph by hand or using technology. Use complete sentences and show all translations on your graph. p(t) + 1 p(t + 1) −1 • p(t)

Best ResponseYou've already chosen the best response.1is log10t a base 10 or log(10t) ?

Best ResponseYou've already chosen the best response.1https://www.google.com/webhp?sourceid=chromeinstant&ion=1&espv=2&es_th=1&ie=UTF8#q=y+%3D+log(x) what is x when y = 1 what is x when y = 0

Best ResponseYou've already chosen the best response.1welll it's not making much sense because I assume pH can't be negative >.>

Best ResponseYou've already chosen the best response.0I did the graph I think it is .20 for when y = 1 and 1 when y =0

Best ResponseYou've already chosen the best response.1*scratches head* water pH = 7 7 = log10t find t ? but he has to raise t by 0.5 so 7 = log10(t+0.5) perhaps

Best ResponseYou've already chosen the best response.1or they mean 0.5 = t solve for p(t)

Best ResponseYou've already chosen the best response.1aka look at x = 0.5 on the graph y = ?

Best ResponseYou've already chosen the best response.0so is 7 = log10(t+0.5) the function you are most positive with
