simplify the expression below and state the value of m for which the simplified expression is not defined 2m² + m - 15/ m² - 9​
motikmotik

Answer:

  • The simplified expression is: \frac{2m-5}{m-3}
  • The simplified expression is undefined for m=3

Explanation:

The given expression is:

\frac{2m^2+m-15}{m^2-9}

The numerator can be siplified by using factorization and denominator will be simplified using the formula

a^2-b^2 = (a+b)(a-b)

So,

= \frac{2m^2+6m-5m-15}{(m)^2-(3)^2}\\=\frac{2m(m+3)-5(m+3)}{(m-3)(m+3)}\\=\frac{(2m-5)(m+3)}{(m-3)(m+3)}\\=\frac{2m-5}{m-3}

A fraction is undefined when the denominator is zero. In order to find the value of m on which the simplified fraction will be undefined we will put denominator equal to zero.

So,

m-3 = 0 => m = 3

Hence,

  • The simplified expression is: \frac{2m-5}{m-3}
  • The simplified expression is undefined for m=3

Display flight number, origin, destination, fl_orig_time as --"Departure Time", fl_dest_time as "Arrival Time". Format times in
NARA [144]

Answer:

Select "flight number", origin, destination, format(fl_orig_time, 'HH:mm' ) as "Departure Time", format(fl_dest_time, 'HH:mm') as "Arrival Time" from table_name order by flight_number

Explanation:

The script is used to select records from the table named 'table_name' and formatted to 24hr time format with the hour in capital letters (signifying 24 hrs). Then the inverted comma used for flight number is due to the space character ebtween the two words. In a select statement, order by comes after the table name. While as is used as an alias for a column in a table.

Windows domain policy to disable windows 10 update
Greeley [361]

Group Policy, change the setting "Turn off the upgrade to the latest version of Windows through Windows Update," which can be found in Computer Configuration / Administrative Templates / Windows Components / Windows Update.

Doing so sets the registry value described in the rest of this step. Note that for Home versions of Windows 7 and 8.1, where the Group Policy editor is not available, editing the registry is the only option.

To make this change with Regedit, navigate to the following key.

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate

Important: If that key doesn't exist, you'll need to create it.

Create a DWORD value called DisableOSUpgrade and set it to 1. (If that sentence makes no sense, you probably shouldn't be using Regedit.)
