Lets say for arguments sake that the bag contained 2 blue and 3 red marbles
p:q = 2:3 In order to get a ratio of 2:1 we would have to add 4 blue marbles
(6:3 = 2:1).
So the ratio p to r = 2:4 = 1:2 answer.
That is the pH scale
pH = - log of the concentration of hydrogen ions in a solution.

Step-by-step explanation:
we know that
The graph is a vertical parabola open upward
The vertex is the point (0,1)
The equation of a vertical parabola in vertex form is equal to

substitute the vertex in the equation


<em>Find the value of coefficient a </em>
Observing the graph
For x=1, y=3
substitute in the equation


The equation on the graph is equal to

Answer:
