Short answer: 3240 handshakes.
Remark
If you watch hockey, you've actually seen this happen. After the game, the winning team will stay on the ice usually on center ice. As you look at them, the man on your right will go down the line and rough up or shake hands or say something to each of his teammates on the line. Then he goes into the dressing room. So he has talked to n - 1 people. The next person going down the line will talk to n - 2 people. and so on all the way down the line.
Formula
Sum = (n + 1)*n/2 is what the formula is.
Givens
n = 80
Sub and Solve
Sum = (80 + 1)*80 / 2
Sum = 81 * 40
Sum = 3240 handshakes.<<<<< Answer

Answer:
27 hours
Step-by-step explanation:
The parent function is given by 
and the transformation function is given by 
We can see that, 6 has been added to the function f(x) to get the function g(x).
We know that when we add some constant 'c' in the function then the function gets shifted upward by 'c' units.
Therefore, we will get g(x), when we will shift f(x) upward by 6 units.
Both functions are linear function hence, the asymptote of g(x) is the asymptote of f(x) shifted six units up.
D is the correct option.
