What do you need help with? it helps us to know the question!
In chemistry, the acidity of a solution is measured using the pH scale 0-14. A solution that's pH 3 is 10 times more acidic than a solution that's pH 4. The lower the pH the more acidic something is. The higher the pH the more basic something is. Water is generally around pH 7 (calculated using logarithms)
Also, in seismology. <span>Vibrations are picked up and plotted on a seismograph. The strength, or magnitude, of an earthquake is measured using the Richter scale. The Richter scale is numbered 0-10.
</span><span>
</span><span>So an earthquake thats a 5 on the Ricter scale is 10 times stronger/bigger than one that's a 3. (Logarithms)

Biologists that calculate population growth, whether animal, human or microorganism. When organisms create more organisms in a population they grow exponentially. (exponential functions)
Also, a lot of financial things like compound interest on a saving account or loan. (exponential function)

Answer:
go to 7 on the y Axis, point it, the go up 1 and over 2, then point that.
Answer:
-8.4
Step-by-step explanation:
Because if you want to find the opposite of a number then you find that same number on the other side on the number line for example, -4.5 you would go on the other side and you would get positive 4.5
You dont get duplicates in the set so although there are 2 red pens it only appears once in the set.
So the correct answer is D
