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

Answers

Answer:

The simplified expression is: $(2m-5)/(m-3)$

The simplified expression is undefined for m=3

Explanation:

The given expression is:

$(2m^2+m-15)/(m^2-9)$

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,

$= (2m^2+6m-5m-15)/((m)^2-(3)^2)\n=(2m(m+3)-5(m+3))/((m-3)(m+3))\n=((2m-5)(m+3))/((m-3)(m+3))\n=(2m-5)/(m-3)$

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: $(2m-5)/(m-3)$

The simplified expression is undefined for m=3

When possible, you should avoid using _________ variables in a program?

Answers

Answer:

Global variable

Explanation:

You should avoid using global variables in a program because global variables can be accessed by any part of the code and every function or any part of the code has the tendency to alter or modify its value. One can't limit the scope or in other words one cant simply force any part of the program not to use them or modify it's values. Testing of large programs also becomes difficult as it is hard to keep track of the functions reading and modifying the values of global variables

13. The Save As command is useful if you want to copy an open document and A. give the copy a new name.
B. remain in the original document.
C. delete the original document.
D. link it to the original document.

Answers

the answer would be A because when you first press Save As you are creating it then you would just press save every time you have tweaked it but if you wanted to shop that you had tweaked it (for example) then you would press Save As. I may be entirely wrong so don't just use my answer!!

A. give the copy a new name

can Results shown at the top of the Google search engine results page (SERP) always get high Needs Met ratings

Answers

I think it can't.

The one that get high needs met rating are the pages that satisfy the user's search. The search engine result page that shown at the top of the result doesn't necessarily fulfil this criteria

A disk drive manufacturer sells storage devices with capacities of one terabyte, 500 gigabytes, and 100 gigabytes with probabilities 0.5, 0.3, and 0.2, respectively. The revenues associated with the sales in that year are estimated to be $50 million, $25 million, and $10 million, respectively. Let X denote the revenue of storage devices during that year. Determine the probability mass function of X.

Answers

Answer and Explanation:

As per the question:

The Probability Mass function also known as frequency function of the variable X can be defined as a capacity or function that gives the likelihood that a discrete arbitrary variable is actually equivalent to some value.

From the question it can be given as:

f(50) = P(X = 50) = 0.5

f(25) = P(X = 25) = 0.3

f(10) = P(X = 10) = 0.2
