Apple juice has a pH of 2.9, and water has a pH of 7.0. Which substance has a higher concentration of hydronium ions, and how much higher is it? Use the formula pH=-log |H3O+| , where |H3O+| represents the hydronium ion concentration. has a higher concentration of hydronium ions. Its hydronium ion concentration is times higher than in the other liquid.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

d. corresponding side lengths in similar triangles are proportional in length.

step-by-step explanation:

you should talk someone who owns the website about it. you did not deserve to have all that hard work and time taken away. id watch videos of little puppies to cool you down, and maybe some nacho cheese doritos.
