Answer:
exact value: ![x= \frac{log25}{4}](https://tex.z-dn.net/?f=x%3D%20%5Cfrac%7Blog25%7D%7B4%7D)
approximate: x=0.349485
Step-by-step explanation:
Exact Value:
![10^{4x} = 25](https://tex.z-dn.net/?f=10%5E%7B4x%7D%20%3D%2025)
![log (10^{4x})= log 25](https://tex.z-dn.net/?f=log%20%2810%5E%7B4x%7D%29%3D%20log%2025)
![4x = log 25](https://tex.z-dn.net/?f=4x%20%3D%20log%2025)
![x= \frac{log25}{4}](https://tex.z-dn.net/?f=x%3D%20%5Cfrac%7Blog25%7D%7B4%7D)
Approximate:
![x= \frac{log25}{4}](https://tex.z-dn.net/?f=x%3D%20%5Cfrac%7Blog25%7D%7B4%7D)
![x=1.39794/4\\](https://tex.z-dn.net/?f=x%3D1.39794%2F4%5C%5C)
![x=0.349485](https://tex.z-dn.net/?f=x%3D0.349485)
Answer:
The answer is
<h2>
![67\%](https://tex.z-dn.net/?f=67%5C%25)
</h2>
Step-by-step explanation:
To find the percentage increase we use the formula
<h3>
![Percentage \: change = \frac{change}{original \: \: quantity} \times 100\%](https://tex.z-dn.net/?f=Percentage%20%5C%3A%20%20%20change%20%3D%20%20%5Cfrac%7Bchange%7D%7Boriginal%20%5C%3A%20%20%5C%3A%20quantity%7D%20%20%5Ctimes%20100%5C%25)
</h3>
From the question
The original value = 12
To find the change we subtract the smaller value from the larger one
That's
Change = 20 - 12 = 8
So the percentage increase is
<h3>
![\frac{8}{12} \times 100 \%\\ = \frac{2}{3} \times 100\% \\ = 66.67\%](https://tex.z-dn.net/?f=%20%5Cfrac%7B8%7D%7B12%7D%20%20%5Ctimes%20100%20%5C%25%5C%5C%20%20%3D%20%20%5Cfrac%7B2%7D%7B3%7D%20%20%5Ctimes%20100%5C%25%20%5C%5C%20%20%3D%2066.67%5C%25)
</h3>
We have the final answer as
to the nearest whole number
