Answer:
x = 2 if you are trying to solve for x
Step-by-step explanation:
Answer:
r=3 where r is the common ratio
Step-by-step explanation:
The sum of geometric progression for n terms is given by:
, where
is the
first term of the series and r is the common ratio.
Now, according to the question, there are four terms and they form a geometric progression. So sum of four terms is given as
and
.
Also according to the above formula:
![S_{4}=a_{1} ( 1-r^{4})/ 1-r](https://tex.z-dn.net/?f=S_%7B4%7D%3Da_%7B1%7D%20%28%201-r%5E%7B4%7D%29%2F%201-r)
Using the values as given in the question into the above equation we get:
![1+r =1/10 ( 1-r^{4})/ 1-r](https://tex.z-dn.net/?f=1%2Br%20%3D1%2F10%20%28%201-r%5E%7B4%7D%29%2F%201-r)
![(1+r)(1-r)=1/10 ( 1-r^{4})](https://tex.z-dn.net/?f=%281%2Br%29%281-r%29%3D1%2F10%20%28%201-r%5E%7B4%7D%29)
[ Using formula
]
![(1-r^{2})=1/10 ( 1-r^{2})(1+r^{2})](https://tex.z-dn.net/?f=%281-r%5E%7B2%7D%29%3D1%2F10%20%28%201-r%5E%7B2%7D%29%281%2Br%5E%7B2%7D%29)
![10=(1+r^{2})](https://tex.z-dn.net/?f=10%3D%281%2Br%5E%7B2%7D%29)
![10-1=(r^{2})](https://tex.z-dn.net/?f=10-1%3D%28r%5E%7B2%7D%29)
![\sqrt{9}=(r)](https://tex.z-dn.net/?f=%5Csqrt%7B9%7D%3D%28r%29)
which is the required answer.
Answer:
zero: x = 0
discontinuities: x = -5, x = 5
Step-by-step explanation:
The zeros of the rational function will be found where the numerator is zero. That will happen when x=0.
__
There will be discontinuities where the denominator is zero. The denominator is the difference of squares, so factors as ...
x^2 -25 = (x -5)(x +5)
These factors will be zero when x=5 and x=-5.
