★ Oblique Asymptote ★

f(x) =  \frac{x {}^{2}  + 5x + 6}{x - 4} \\ f(x) = (x - 4)(x + 9) + 42 \\
Hence , oblique Asymptote is obtained simultaneously by the Quotient of the function obtained ,
HENCE , oblique Asymptote is

Answer:

y=x+9.

Step-by-step explanation:

the function is \frac{x^{2}+5x+6}{x-4}. Now, the equation of the oblique asymptote is a function y= mx + b where

m = \lim_{x \to \infty} \frac{f(x)}{x}

and b = \lim_{x \to \infty} f(x)-mx

So,

m =  \lim_{x \to \infty} \frac{\frac{x^{2}+5x+6}{x-4}}{x}

= \lim_{x \to \infty} \frac{x^{2}+5x+6}{x^{2}-4x}= 1.

and,

b = \lim_{x \to \infty}\frac{x^{2}+5x+6}{x-4}-x

=  \lim_{x \to \infty}\frac{x^{2}+5x+6-x^{2}+4x}{x-4}

=  \lim_{x \to \infty}\frac{9x+6}{x-4}= 9.

Then, the equation of the oblique asymptote is y= x+9.

From a group of 12 students, we want to select a random sample of 4 students to serve on a university committee. How many combin
borishaifa [10]

Answer:

495 combinations of 4 students can be selected.

Step-by-step explanation:

The order of the students in the sample is not important. So we use the combinations formula to solve this question.

Combinations formula:

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

How many combination of random samples of 4 students can be selected?

4 from a set of 12. So

C_{n,x} = \frac{12!}{4!(8)!} = 495

495 combinations of 4 students can be selected.
