Firstly, the word rational...is derived from ratio..which in simple terms ..is a fraction. a rational function, like all functions, must contain both an independent and dependent variable. The general form of a function is y = f(x), where y [the dependent variable] is based on the value of x [ the independent variable. So, to answer the question, a rational function, is one that involves a rational expression, such as y = 23x/2.

densk [106]

Answer:

(2, 0) and (6, 0)

Step-by-step explanation:

$y = x^2 - 8 x + 12$

To get the x intersept put y = 0

$x^2 - 8 x + 12 = 0 \\\\x^2 - 6 x - 2 x + 12 = 0 \\\\x(x- 6) - 2(x - 6) = 0 \\\\(x - 2) (x - 6) = 0 \\\\x = 2 and x = 6$

So, the intersepts are

(2, 0) and (6, 0)

A certain list consists of 21 different numbers. if n is in the list and n is 4 times the average (arithmetic mean) of the other

Helen [10]

If x is the average of "the other 20 numbers", then their sum is 20x. Adding the 21st number makes the sum of all 21 numbers be 20x +4x = 24x.

The 21st number, 4x, is 4x/(24x) = 1/6 of the total of all numbers,

Andrew has aflying disc with a radius of 10 centimeters. What is the circumstance of the disc?

Gnom [1K]

To find out the circumference of a circle, you have to multiply the diameter of the circle with pi.(3.14)

First, to get the diameter of a circle you have to multiply the radius by 2.

$10*2=20
$

The diameter is 20 centimeters.

Then, multiply the diameter by pi.(3.14)

$20*3.14=62.8$

The circumference is 62.8 centimeters.
