In this geometric sequence for an exponential model I will be graphing based on this data,     term $1 = 50,000$ and term $10 = 309,587$.   I do not know how to find the common ratio based solely on this data.  (This is not the same as "how to find the common ratio of a geometric sequence) because my question is on, how would you find the common ratio with a missing internal number, say, term 1 and term 10 as opposed to term 1 and term 2.  I know that if this were an arithmetic sequence, I would convert all of my data into an explicit equation $f(n)=f(1)+d(n-1)$ in this case,   $$ \begin{align*} 309,587 &amp;= 50,000 + (10-1)d\\ \implies 309587 - 50000 &amp;= 9d\\ \implies d &amp;= 28843 \end{align*} $$  I do not think this would be the same for a geometric sequence for example $f(n) = f(1) * d(n-1)$ or in this case, $309,587 = 50,000 * (10-1)d$ and then do $309587 - 50000 = 9d$, $d = 28843$ as for the arithmetic sequence, because that is arithmetic(adding) and this is geometric (multiplying).  I need to know how to find the common ratio of a geometric sequence given term $1$ and term $10$.
A geometric sequence has its first term equal to $12$ and its fourth term equal to $-96$.   How do I find the common ratio? And find the sum of the first $14$ terms
How to get the day, year, hours, min Individually from date format "yyyy-MM-dd'T'HH:mm:ss.SSSZ"? Can I get more than 1000 records from a DirectorySearcher? I just noticed that the return list for results is limited to 1000. I have more than 1000 groups in my domain (HUGE domain). How can I get more than 1000 records? Can I start at a later record? Can I cut it up into multiple searches?  Here is my query:  DirectoryEntry dirEnt = new DirectoryEntry("LDAP://dhuba1kwtn004"); string[] loadProps = new string[] { "cn", "samaccountname", "name", "distinguishedname" }; DirectorySearcher srch = new DirectorySearcher(dirEnt, "(objectClass=Group)", loadProps); var results = srch.FindAll();   I have tried to set srch.SizeLimit = 2000;, but that doesn't seem to work.

Minimal $ab$ for Rational Number $a/b$ in an Interval Given rational numbers $L$ and $U$, $0&lt;L&lt;U&lt;1$, find rational number $M=a/b$ such that $L \le M&lt;U$ and $(a\times b)$ is as small as possible---$a$ and $b$ are integers. For example,    If $L=66/101$ and $U=19/29$ then $M=17/26$. If $L=66/101$ and $U=19/28$ then $M=2/3$.   Right now I'm using a naive search that is exponential in complexity. Is there a better method?  If it is of any help, it can be assumed the prime factorization of numerator and denominator of $U$ and $L$ are known. When a land becomes creature, can you kill it?

Can Git hook scripts be managed along with the repository? We'd like to make a few basic hook scripts that we can all share -- for things like pre-formatting commit messages.  Git has hook scripts for that that are normally stored under &lt;project&gt;/.git/hooks/.  However, those scripts are not propagated when people do a clone and they are not version controlled.    Is there a good way to help everyone get the right hook scripts?  Can I just make those hook scripts point to version controlled scripts in my repo? Normal subgroup of prime index Generalizing the case $p=2$ we would like to know if the statement below is true.  Let $p$ the smallest prime dividing the order of $G$. If $H$ is a subgroup of $G$ with index $p$ then $H$ is normal. How to format a USB drive? Is is possible to skip the confirmation step while adding a repository? When I add a repository by running  sudo add-apt-repository ppa:ubuntu-x-swat/x-updates   It outputs this dialog:  Updated versions of X.org drivers, libraries, etc. for Ubuntu.  This PPA is for stable upstream releases of X.org components.  If you're looking for something even more bleeding-edge, please see the xorg-edgers PPA.  While Ubuntu does not "officially/formally" support these packages, if you discover problems when installing these debs please feel free to report bugs to launchpad.  However, please make sure to clearly state that you are running packages from this PPA so we know the fixes need to come here.  If you are upgrading from one release to another with this PPA activated, please install the ppa-purge package and use it to downgrade everything in here beforehand. sudo ppa-purge ppa:ubuntu-x-swat/x-updates will do it.

I want to know if this is grammatically correct " How long would the conference be for?". proving the inequality $\triangle\leq \frac{1}{4}\sqrt{(a+b+c)\cdot abc}$ How can we prove that $D(f)\backsimeq\operatorname{Spec} A_f$? Let $$D(f)=\operatorname{Spec}A - V(f)=\{p\in \operatorname{Spec} A:f\notin p\}$$ be the principal open subsets of $\operatorname{Spec}A$ with the Zariski topology. I'm trying to prove that $D(f)\backsimeq \operatorname{Spec} A_f$, where $A_f$ is the localization of $A$ at $f$.  If we consider the canonical homomorphism $\varphi:A\to A_f$ given by $\varphi (a) = \frac {a}{1}$, we can define $\varphi':\operatorname{Spec} A_f\to \operatorname{Spec} A$, given by $\varphi'(p)=\varphi^{-1}(p),\forall p\in \operatorname{Spec}A_f$.  I'm having trouble proving that this map is surjective.  Thanks. QGIS 2.99 "qgis._core import error: DLL load failed" I am trying to run a standalone application.
