Explain why 5x4−6x7+15x4−6x7+1 is considered as a rational function?

Mathematics

Hitman42 [59]3 years ago

A rational function is a function that can be written as the quotient of two polynomials.

You did write:

"5x4−6x7+15x4−6x7+1"

This is not a rational function, but I guess that there is some kind of mistake in what you wrote, as the division sign may be missing.

A rational function would actually be:

\frac{5*x^4 - 6*x^7}{15*x^4 - 6*x^7 + 1}

Where this is considered a rational function because we have the quotient of two polynomials:

p(x) = 5*x^4 - 6*x^7

q(x) = 15*x^4 - 6*x + 1

The Magic Dragon has 2013 heads. Leo the Brave is cutting off the Dragon's heads at a speed of 5 heads per minute. The Dragon's
aivan3 [116]

Answer:  The answer is 1833 heads  and 11 hours, 11 minutes.


Step-by-step explanation:  Given that the Magic Dragon has 2013 heads. The brave Leo is cutting off the Dragon's heads at a speed of 5 heads per minute. But, the Dragon's heads are growing back at a speed of 2 heads per minute.

So, the number of heads of Dragon that are decreasing per minute = 3.

Therefore, after 1 hour, i.e., 60 minutes, The number of heads of the Dragon

= 2013 - 60 × 3 = 2013 - 180 = 1833 heads.

Now, the fight will last until all the heads of the Dragon are cut. Let the fight lasts for 'x' minutes, then

2013-x\times 3=0\\\\\Rightarrow 3x=2013\\\\\Rightarrow x=\dfrac{2013}{3}=671.

Hence the fight lasts for 671 minutes, i.e., 11 hours and 11 minutes.

Thus, the Dragon will have 1833 heads after 1 hour and the fight will last for 11 hour and 11 minutes.

What's The slope intercept form of: x - y = 7
Brilliant_brown [7]
Y=x-7 this is because you subtracted the x to both sides. Since y is a negative, you divide by -1 causing the -x to turn positive and the positive seven to be negative seven.
