Answer:
120
Step-by-step explanation:
The number of friends is 5 and there are 5 seats only. So , we can find it out with the help of permutations ,
⇒ 5! / (5-5)!
⇒ 5! / 1!
⇒ 5!
⇒ 5 × 4 × 3 × 2 × 1
⇒ 120
<h3><u>Hence </u><u>there</u><u> </u><u>are</u><u> </u><u>1</u><u>2</u><u>0</u><u> </u><u>ways</u><u> </u><u>by</u><u> </u><u>which </u><u> 5 friends sit together at the movies in 5 seats</u><u>. </u></h3>Answer:
- 4
- -4
Step-by-step explanation:
When you follow the curve from the left toward x=2, you wind up at the open circle at (2, 4). The limit from that direction is 4.
When you follow the curve from the right toward x=2, you wind up at the open circle at (2, -4). The limit from that direction is -4.
