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>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)
hope this helps
To solve for x, simply rearrange the problem:
Answer:
Reflection and a Dilation (I'm not too sure if this is correct hopefully it helps)
Step-by-step explanation:
Notice the picture below
now, we know their perimeter are the same for both
thus 4(a+4) = 6a
solve for "a"
Answer:
A, B, C, and D
Step-by-step explanation:
all answer choices are the same
