Answer:

If the positions are distinct, as in executive offices, then P(9,5)

P(9,5) = 9!/(9 - 5)! = 15120..... is the answer

But...

If the positions are equivalent, such as seats in a legislative body, then C(9,5)

C(9,5) = 9!/[(9 - 5)!(5!)] = 126

Hope this can help you :)

Please help. Thank you.
Marysya12 [62]

The answer would be 24pi inches.

You can find this by using the formula for a circumference and plugging in the value of the radius.

C = 2pi*r

C = 2pi * 12

C = 24pi

Use the formula to solve the problem. Round to the nearest hundredth.
Zepler [3.9K]

Answer:

Volume of sphere = 4.186 cubic inches

Step-by-step explanation:

Radius of sphere = r = 1 inch

Volume of sphere = ?

The formula used is: Volume\:of\:sphere=\frac{4}{3}\pi r^3

Putting value of radius and π and finding volume:

Volume\:of\:sphere=\frac{4}{3}\pi r^3\\Volume\:of\:sphere=\frac{4}{3}\times 3.14\times (1)^3\\Volume\:of\:sphere=\frac{4}{3}\times 3.14\times (1)^3\\Volume\:of\:sphere=4.186 \:cubic\:in

So, Volume of sphere = 4.186 cubic inches

larisa86 [58]

Step-by-step explanation:

[( {27})^{n + 2}  - 6 \times  {3}^{3n + 3} ]  \div  {9}^{n + 2}  \times  {3}^{n}  \\  \\   =  [(  {3}^{3}) ^{n + 2}  - 2 \times 3 \times  {3}^{3n + 3} ]  \div  {( {3}^{2}) }^{n + 2}  \times  {3}^{n}  \\  \\  =  [ {3} ^{3n + 6}  - 2 \times  {3}^{3n + 4} ]  \div  {{3}}^{2n + 4}  \times  {3}^{n} \\  \\  =  [ {3} ^{3n + 4}  ( {3}^{2} - 2 ) ]  \div  {{3}}^{3n + 4}   \\  \\  =  \frac{ {3} ^{3n + 4}  (9- 2 ) }{{{3}}^{3n + 4}   }  \\  \\  = 7 \\
