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}

4. A credit card company applies a 6% fee on all transactions under $10. You purchased coffee for $4.80. What fee amount will be
Akimi4 [234]

Answer:

The fee amount applied to my bill will be $0.288 or 28.8 cents.

Step-by-step explanation:

The coffee cost under $10; therefore, a 6% fee will be applied.

6% of $4.8 is

\dfrac{6\%}{100\%}  * \$ 4.80

0.06*\$4.80 = \$0.288.

Thus, the fee amount applied to my bill will be $0.288 or 28.8 cents.
