I believe the answer is C. third choice

<span>f(x) ≥ 0 over the interval [–1, 1].</span>

Answer:

A 2-column table with 7 rows. The first column is labeled x with entries negative 3, negative 2, negative 1, 0, 1, 2, 3. The second column is labeled f of x with entries 15, 0, 3, 0, negative 3, 0, 15.

Predict which statements are true about the intervals of the continuous function. Check all that apply. ITS B,D,E

f(x) > 0 over the interval (−, 3).

f(x) ≤ 0 over the interval [0, 2].

f(x) < 0 over the interval (−1, 1).

f(x) > 0 over the interval (–2, 0).

f(x) ≥ 0 over the interval [2, ).

<h2>Answer:</h2>

(a) P(11,5)= 55440

(b) C(11,5)=462

<h2>Step-by-step explanation:</h2>

We know that the permutation is the number of ways of arranging r items out of a total of n items and is given by:

$P(n,r)=\dfrac{n!}{(n-r)!}$

and the combination is the number of ways of choosing r items out of a total of n items and is given by:

$C(n,r)=\dfrac{n!}{r!\times (n-r)!}$

(a)

P(11,5)

$P(11,5)=\dfrac{11!}{(11-5)!}\\\\P(11,5)=\dfrac{11!}{6!}\\\\P(11,5)=\dfrac{11\times 10\times 9\times 8\times 7\times 6!}{6!}\\\\P(11,5)=11\times 10\times 9\times 8\times 7\\\\P(11,5)=55440$

(b)

C(11,5)

$C(11,5)=\dfrac{11!}{5!\times (11-5)!}\\\\C(11,5)=\dfrac{11!}{5!\times 6!}\\\\C(11,5)=\dfrac{11\times 10\times 9\times 8\times 7\times 6!}{5\times 4\times 3\times 2\times 1\times 6!}\\\\C(11,5)=462$

What is 5p to the -7 power/20p to the 2 power simplified

mr_godi [17]

Answer:

p^(-9) or 1/p^9

Step-by-step explanation:

Here we have:

(5p)^(-7)

----------------

(20p)^2

Let's temporarily remove the coefficient 5/20 and reduce it to 1/4.

then we have:

1 1 1

(1/4) ------------- = (1/4) -------------- = ------------

p^7*p^2 p^(7 + 2) p^9
