This is an interesting question. I chose to tackle it using the Law of Cosines.
AC² = AB² + BC² - 2·AB·BC·cos(B)
AM² = AB² + MB² - 2·AB·MB·cos(B)
Subtracting twice the second equation from the first, we have
AC² - 2·AM² = -AB² + BC² - 2·MB²
We know that MB = BC/2. When we substitute the given information, we have
8² - 2·3² = -4² + BC² - BC²/2
124 = BC² . . . . . . . . . . . . . . . . . . add 16, multiply by 2
2√31 = BC ≈ 11.1355
There is a total of 10 games played.
<h3>
How many games are played?</h3>
There are 5 players, If we select a given player, then that player will play one game with each of the other 4 players.
So we have 4 games at the moment.
Now we select one of the other 4 players, (we don't count the one we choose before). The one that we choose now will play one game wich each one of the remaining 3, so we add 3 more games.
Now we do the same with the remaining 3, this time we add 2 more games.
Now we do that with the remaining 2, now we add 1 more game.
Adding all the games we have:
4 + 3 + 2 + 1 = 10
There is a total of 10 games played.

Answer:
Step-by-step explanation:
Given equation:
In the given equation, is a coefficient and y is the variable.
coefficient is a constant number or quantity multiplied to a variable in an algebric expression. Like in the above equation is a coefficient and y is the variable. We use term variable for y as its value may vary or change. If variable does not have any coefficient in any expression then in that case, we consider 1 as coefficient, for example: , here variable have 1 as coefficient.
Hence, the fractional coefficient is .
Answer:
60 mintues
