Evaluate the expression. P(9, 3) · P(5, 4)

boyakko [2]

Answer:

$P(9,3) *P(5,4)$

And if we use the permutation formula given by:

$nPx = \frac{n!}{(n-x)!}$

And replacing we got:

$\frac{9!}{6!} \frac{5!}{4!}= 504*5 = 2520$

Step-by-step explanation:

For this problem we want to find the following expressionÑ

$P(9,3) *P(5,4)$

And if we use the permutation formula given by:

$nPx = \frac{n!}{(n-x)!}$

And replacing we got:

$\frac{9!}{6!} \frac{5!}{4!}= 504*5 = 2520$

(X-2)²+(y-1)²=25 how do you do this problem?

Tasya [4]

$(x-x_c)^2+(y-y_c)^2=r^2\\
(x_c,y_c) - \text{center}\\\\
(x-2)^2+(y-1)^2=25\\
\text{center}=(2,1)\\
r=\sqrt{25}=5$

A bug lands on a windshield wiper blade before it is flung off. The wiper blade and arm assembly have a length of 30 inches. If

sveticcg [70]

Answer:

35.6047 inches

Step-by-step explanation:

The wiper blade moves in a circular way, where the radius is 30 inches.

To find how far the bug travelled, we just need to use a rule of three, where the length of the circunference relates to a angle of 360 degrees:

360 degrees -> 2 * pi * radius

68 degrees -> distance

distance * 360 = 2 * pi * radius * 68

distance = 2 * pi * 30 * 68 / 360 = 35.6047 inches
