The pH of a solution is a measure of how acidic it is. The greater the acidity, the lower the pH. The
function f(x) = -log x gives the pH of a solution,
where x is the concentration of hydrogen ions, in
moles per liter.
The graph of f(x) = -log x is a
of the graph of
g(x) = log x.

the answer is a if my teacher taught me correct

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
