Imagine that there are currently three major cell phone service providers available in the United States. The largest one has en
erik [133]

Answer:

explanation below

Step-by-step explanation:

Large companies in most cases, buy other smaller firms to benefit from their products or to snap up the talents they have in their system. There are also cases in which such acquisitions are made to destroy competition the smaller companies present.  

This form of acquisition can be termed “killer acquisition as the larger group tends to terminate the projects of the smaller companies and shelve whatever competing innovative projects they have before they can hit the markets with them.  

This type of scenario is known to be quite pervasive and could in some ways be very detrimental to the society. When competition is eliminated, people buy whatever they see with no alternatives around and in most cases, they pay exorbitant amount of money for telco products and services.

What is the following quotient? 5/√11-√3
kati45 [8]

ANSWER

\frac{5( \sqrt{11}  +  \sqrt{3} )} {8}

EXPLANATION

The given rational function is

\frac{5}{ \sqrt{11} -  \sqrt{3}}

We need to rationalize the denominator by multiplying both the numerator and the denominator by the conjugate of

\sqrt{11}  -  \sqrt{3}

which is

\sqrt{11}   +  \sqrt{3}

When we rationalize we obtain:

\frac{5( \sqrt{11}  +  \sqrt{3} )}{(\sqrt{11}  - \sqrt{3} )( \sqrt{11}  +  \sqrt{3} )}

The denominator is now a difference of two squares:

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

We apply this property to get

\frac{5( \sqrt{11}  +  \sqrt{3} )}{( \sqrt{11}) ^{2}    -  ( \sqrt{3}) ^{2}  )}

\frac{5( \sqrt{11}  +  \sqrt{3} )}{11   -  3}

This simplifies to

\frac{5( \sqrt{11}  +  \sqrt{3} )} {8}

Or

\frac{5 }  {8}\sqrt{11}  + \frac{5 }  {8}\sqrt{3}

<h3>What are fractions?</h3>

A fraction is a quantity that is not a whole number. In maths, a fraction usually has a numerator and a denominator. The numerator is the number above. While the denominator is the number below.

In order to write 4/6 as 2/3 we have to express in its simplest form. This means that you have to divide 4/6 by 2. In order to write 4/6 as 8/23, multiply 4/6 by 2.
