Answer:
is not a factor of the function
.
Step-by-step explanation:
If
is a factor of the function
if and only if
. We must evaluate the polynomial at given value of
to confirm or discard the statement:


Which means that
is not a factor of the function
.
Answer:
x = 1 and y = 2
the second one x = 2 and y = 1
Step-by-step explanation:
Assuming "root 9 of n" is supposed to mean "the ninth root of n", that is
![\sqrt[9]n](https://tex.z-dn.net/?f=%5Csqrt%5B9%5Dn)
we can use the ratio test, which says the series converges whenever
![\displaystyle\lim_{n\to\infty}\left|\frac{\frac{x^{n+1}}{\sqrt[9]{n+1}}}{\frac{x^n}{\sqrt[9]n}}\right|](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Clim_%7Bn%5Cto%5Cinfty%7D%5Cleft%7C%5Cfrac%7B%5Cfrac%7Bx%5E%7Bn%2B1%7D%7D%7B%5Csqrt%5B9%5D%7Bn%2B1%7D%7D%7D%7B%5Cfrac%7Bx%5En%7D%7B%5Csqrt%5B9%5Dn%7D%7D%5Cright%7C%3C1)
We have
![\displaystyle|x|\lim_{n\to\infty}\frac{\sqrt[9]n}{\sqrt[9]{n+1}}=|x|\sqrt[9]{\lim_{n\to\infty}\frac n{n+1}}=|x|](https://tex.z-dn.net/?f=%5Cdisplaystyle%7Cx%7C%5Clim_%7Bn%5Cto%5Cinfty%7D%5Cfrac%7B%5Csqrt%5B9%5Dn%7D%7B%5Csqrt%5B9%5D%7Bn%2B1%7D%7D%3D%7Cx%7C%5Csqrt%5B9%5D%7B%5Clim_%7Bn%5Cto%5Cinfty%7D%5Cfrac%20n%7Bn%2B1%7D%7D%3D%7Cx%7C%3C1)
which means the radius of convergence for this power series is 1.
The Red marble has a 6/10 (60%) chance of gettinv picked while the blue marbles have a 4/10 (40%) chance of getting picked.
Answer:
£10386.34
Step-by-step explanation:
The amount in an account for a principal P saved at compound interest for a period of n years at an annual rate of r% is calculated using the formula:

In this case:
Principal, P=£9500
r=1.8%=0.018
n=5 years
Therefore:

At the end of 5 years, Annie will have £10386.34
