LOGARITHMIC FUNCTIO 2) The pH of a solution can be measured with the formula
pH =-log[H^+]
where is the concentration of hydrogen ions in the solution (moll) Solutions with
a pH less than 7 are acidic, and solutions with pri greater than 7 are basic. [H^+]
cannot be negative and cannot be greater than 1.
Use this function to
a Create a graph of the function (consider the scales):
{pH} = -log(H^+)

Line cd passes through points c(1, 3) and d(4, –3). if the equation of the line is written in slope-intercept form, y = mx + b, what is the value of b? –5 –2 1 5

State whether weight is a function of height for the six students and explain. a. yes, height is a function of weight because two students weigh 165 pounds but have different heights. b. no, height is not a function of weight because two students weigh 165 pounds but have different heights. c. yes, weight is a function of height because for each value of height there is one corresponding value of weight. d. no, weight is not a function of height because there is not enough data to determine a function.

In the diagram, the ratios of two pairs of corresponding sides are equal to prove that almn - axyz by the sas similarity theorem, it also needs to be shown that x 6 z un z zz un = 2x zləzz lezy
