Answer: -18

Explanation:

Average rate of change is slope: $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ . Need to find the y-coordinates:

g(x) = -x² - 4x

g(6) = -(6)² - 4(6)

= -36 - 24

= -60

⇒ (6, -60)

g(8) = -(8)² - 4(8)

= -64 - 32

= -96

⇒ (8, -96)

m = $\frac{-96 - (-60)}{8 - 6}$

= $\frac{-36}{2}$

= -18

A positive real number is 6 less than another. If the sum of the square of the two numbers is 38, then finds the numbers.

Serggg [28]

Answer:

There seems to be a typo error but still this has solution.

Let the number be = x

A positive real number is 6 less than another. Means the second will be $(x+6)$

The sum of the square of the two numbers is 38.

$x^{2} +(x+6)^{2} =38$

=> $x^{2} +36+12x+x^{2} =38$

=> $2x^{2}+12x+36 =38$

=> $2x^{2}+12x=2$

=> $2x^{2}+12x-2=0$

Taking out 2 common;

=> $x^{2}+6x-1=0$

Solving this quadratic equation, we get;

$x=-3+\sqrt{10}$ and $x=-3-\sqrt{10}$

As positive number is needed, we have $-3+\sqrt{10}$

or x = $\sqrt{10}-3$

x = 0.162277

And other number is 6.162277.
