Answer:
4
Step-by-step explanation:
This is an <em>infinite geometric series</em>. This has a sum of ![\frac{a}{1-r}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7B1-r%7D)
Where
a is the first term, and
r is the common ratio (one term divided by the previous term)
Let's figure out the first 2 terms by plugging in n = 1 first and then n = 2 for the series.

<u>First term:</u>
![3(\frac{1}{4})^{n-1}\\=3(\frac{1}{4})^{1-1}\\=3(\frac{1}{4})^0\\=3(1)\\=3](https://tex.z-dn.net/?f=3%28%5Cfrac%7B1%7D%7B4%7D%29%5E%7Bn-1%7D%5C%5C%3D3%28%5Cfrac%7B1%7D%7B4%7D%29%5E%7B1-1%7D%5C%5C%3D3%28%5Cfrac%7B1%7D%7B4%7D%29%5E0%5C%5C%3D3%281%29%5C%5C%3D3)
<u>Second term:</u>
![3(\frac{1}{4})^{n-1}\\=3(\frac{1}{4})^{2-1}\\=3(\frac{1}{4})^1\\=3(\frac{1}{4})\\=\frac{3}{4}](https://tex.z-dn.net/?f=3%28%5Cfrac%7B1%7D%7B4%7D%29%5E%7Bn-1%7D%5C%5C%3D3%28%5Cfrac%7B1%7D%7B4%7D%29%5E%7B2-1%7D%5C%5C%3D3%28%5Cfrac%7B1%7D%7B4%7D%29%5E1%5C%5C%3D3%28%5Cfrac%7B1%7D%7B4%7D%29%5C%5C%3D%5Cfrac%7B3%7D%7B4%7D)
<em>Let's see the common ratio:
</em>
<em />
<em>Thus we have a = 3 and r = 1/4</em><em>. Plugging into the formula of the infinite sum, we get:</em>

<em>So, </em><em>the answer is 4</em>
Answer:
Orca Correct, Sea Star Wrong. Heart it if it was helpful :D
Step-by-step explanation:
11-4=7. Orca correct.
Sea star...11-4=7
Wrong its 7, not -7
Answer:
Step-by-step explanation:
It should be 360 Pls mark brainliest
The ratio is 1:5 tbh or that’s what I think ahahahah
You can divide the polygon into a triangle (VMR) and rectangle(VEDR)
VE=5
VR=6
The area for VEDR would be:
area= VE*VR= 5*6= 30
triangle height=3
VR=6
The area for VMR
area= 1/2 * 3 * 6= 9
Total area= 30 + 9 = 39
