Find the value of each expression. Show your work. 9^P^3

1 answer:

4 0

$_n{P}_r = \frac{n!}{(n - r)!}$
$_9P_3 = \frac{9!}{(9 - 3)!}$
$_9P_3 = \frac{9!}{6!}$
$_9P_3 = \frac{9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1}{6 * 5 * 4 * 3 * 2* 1}$
$_9P_3 = 9 * 8 * 7$
$_9P_3 = 72 * 7$
$_9P_3 = 504$

slava [35]

See the explanation

<h2>Explanation:</h2><h2></h2>

Here we have the following points:

$(3,9) \ and \ (-3,-9)$

The point-slope form of the equation of a line is:

$y=ax+b \\ \\ \\ a:Slope \\ \\ b:y-intercept$

So the slope can be found as:

$a=\frac{-9-9}{-3-3} \\ \\ a=\frac{-18}{-6} \\ \\ a=3$

So:

$y=3x+b \\ \\ \\ Finding \ b: \\ \\ For \ x=3, \ y=9: \\ \\ \\ So: \\ \\ 9=3(3)+b \\ \\ b=9-9 \\ \\ b=0$

So the equation is finally:

$y=3x$

This line passes through and is shown below.
