Answer:
x= -0.01984
Step-by-step explanation:
You divide both sides by 3125 to get x alone.
You get x=-0.01984
Hope this helps!
The recursive formula for the geometric sequence is ![a_n=(-\frac{1}{4} )a_{n-1}](https://tex.z-dn.net/?f=a_n%3D%28-%5Cfrac%7B1%7D%7B4%7D%20%29a_%7Bn-1%7D)
Explanation:
The given sequence is ![\{-16,4,-1,........\}](https://tex.z-dn.net/?f=%5C%7B-16%2C4%2C-1%2C........%5C%7D)
We need to determine the recursive formula for the given geometric sequence.
To determine the recursive formula, first we shall find the common difference.
Since, it is a geometric sequence, the common difference can be determined by
![r=\frac{4}{-16} =-\frac{1}{4}](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B4%7D%7B-16%7D%20%3D-%5Cfrac%7B1%7D%7B4%7D)
![r=-\frac{1}{4}](https://tex.z-dn.net/?f=r%3D-%5Cfrac%7B1%7D%7B4%7D)
Hence, the common difference of the given geometric sequence is ![r=-\frac{1}{4}](https://tex.z-dn.net/?f=r%3D-%5Cfrac%7B1%7D%7B4%7D)
The recursive equation for the geometric sequence can be determined using the formula,
![a_n=r(a_{n-1})](https://tex.z-dn.net/?f=a_n%3Dr%28a_%7Bn-1%7D%29)
Substituting the value
, we get,
![a_n=(-\frac{1}{4} )a_{n-1}](https://tex.z-dn.net/?f=a_n%3D%28-%5Cfrac%7B1%7D%7B4%7D%20%29a_%7Bn-1%7D)
Thus, the recursive formula for the geometric sequence is ![a_n=(-\frac{1}{4} )a_{n-1}](https://tex.z-dn.net/?f=a_n%3D%28-%5Cfrac%7B1%7D%7B4%7D%20%29a_%7Bn-1%7D)
The perimeter is 30 im pretty sure
The water pressure is 45 pounds per square inch. The way to
solve this problem is to first divide the distance covered by the diver which
is 99 feet to the distance with corresponding pressure which is 33 feet. Then
multiply what you get with 15 lbs per in^2.
