12 pencils
Step-by-step explanation:
5 + 1 = 50% of the original amount
5 + 1 = 6
50% = 6
6 x 2 = 12 = 100%

Given equation is

It can be written as follows.

Which is of the form

where a=3 and b=4.
We know that the coordinates of the vertices are (a,0) and (-a,0)
Substitute a=3, we get
The vertices are (3,0) and (-3,0).
We know that the coordinates of the foci are (c,0) and (-c,0)
![c=\sqrt[]{a^2+b^2}](https://tex.z-dn.net/?f=c%3D%5Csqrt%5B%5D%7Ba%5E2%2Bb%5E2%7D)
Substitute a=3 and b=4, we get
![c=\sqrt[]{3^2+4^2}=\sqrt[]{9+16}=\sqrt[]{25}=5](https://tex.z-dn.net/?f=c%3D%5Csqrt%5B%5D%7B3%5E2%2B4%5E2%7D%3D%5Csqrt%5B%5D%7B9%2B16%7D%3D%5Csqrt%5B%5D%7B25%7D%3D5)
Substitute c=5, we get
Hence the foci are (5,0) and (-5,0).
Answer:

Step-by-step explanation:
The general formula for the twelfth term of a geometric sequence is:

Where
is the first term and r is the common ratio
In this case we know that:

The equation is:

So for
we look for
