Answer:

\dfrac{r}{s}(6)=\dfrac{3(6)-1}{2(6)+1}

Detailed explanation:

For any two functions f(x) and g(x), we have

\dfrac{f}{g}(x)=\dfrac{f(x)}{g(x)}

Given the functions: r(x)=3x-1 and s(x)=2x+1

Therefore, \dfrac{r}{s}(x)=\dfrac{r(x)}{s(x)}

\Rightarrow\ \dfrac{r}{s}(x)=\dfrac{3x-1}{2x+1}

Evaluating at x = 6, we have

\dfrac{r}{s}(6)=\dfrac{3(6)-1}{2(6)+1}

This expression corresponds to \dfrac{r}{s}(6)=\dfrac{3(6)-1}{2(6)+1}

Simplifying further, the result is \dfrac{r}{s}(6)=\dfrac{18-1}{12+1}=\dfrac{17}{13}

The positive difference between the two roots of the quadratic equation $3x^2 - 7x - 8 = 0$ can be written as $\frac{\sqrt{m}}{n
Svet_ta [12734]

3x² - 7x - 8 = 0

Since we need to calculate square roots, we'll skip factoring and directly apply the quadratic formula,

x = ( 7 ± √(7² - 4(3)(-8))    )/(2(3)) = (7 ± √(49+96))/6 = 7/6 ± √145/6

145 = 5×29, indicating there are no square factors. The positive difference is

d =  (7/6 + √145/6) - (7/6 - √145/6) = 2√145/6 = √145/3

therefore, m=145, n=3 leading to a sum of
