For the answer to the question above asking w<span>hich of the following is true for the rational function f(x) = x-4/x^2-16?
The answer is
</span><span>g(x)=2 / x^2-16 </span>
<span>g(x) = 2 /(x+4)(x-4) </span>

<span>setting the denominator to 0, the vertical asymptotes are x = 4 and x = -4

Suppose we have an urn containing 9 marbles. Two are red, three are green, and four are blue. We randomly select 5 marbles from

Aleonysh [2.5K]

Answer:

probability of selecting 3 green marbles, 1 red marble, and 1 blue marbles

$P(E) =\frac{8}{126} = 0.0634$

Step-by-step explanation:

Given data urn containing '9' marbles

given red marbles = 2

green marbles =3

blue marbles = 4

Five marbles can be selected at a time from '9' marbles in $9_{C_{5} }$ ways

by using formula $n_{C_{r} }=\frac{n!}{(n-r)!r!}$

$9_{C_{5} }=\frac{9!}{(9-5)!5!} = \frac{9X8X7X6X5!}{4!5!}$

After simplification , we get $9_{C_{5} } = 126$

total number of ways n(S) = 126

The probability of selecting '3' green marbles ,one red marble and one blue marble with replacement.

let ' E' be the event of selecting '3' green marbles ,one red marble and one blue marble with replacement.

n(E) = $3_{C_{3} } X2_{C_{1} }X 4_{C_{1} }$ ways

The required probability $P(E) = \frac{n(E)}{n(S)}$

$p(E) = \frac{3_{C_{3} } X2_{C_{1} }X 4_{C_{1} }}{9_{C_{5} } }$

on simplification , we get

$P(E) = \frac{1X2X4}{126} =\frac{8}{126}$

$P(E) =\frac{8}{126} = 0.0634$

M2-n2 factorization plz

Alina [70]

Answer:

(m+n)(m-n)

Step-by-step explanation:

formula: x^2 - y^2 = (x+y)(x-y)

add m and n to x and y to get

m^2 - n^2

then the formula says insert the m and n into the formula answer of (x+y)(x-y) to get our answer of

(m+n)(m-n)
