Acidity is measured on the ph scale. the acidity of a substance is given by ph=−logh, where h is the concentration of hydrogen ions. if a substance has a ph of 6, which equation could be used to find its h value?

Step-by-step explanation:

To solve this question it is important to remember logarithm rules. That is:

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
