I think the correct answer from the choices listed above is the last option. To determine the answer, we substitute 3 and 10 to each choice and see whether the answer would equate to 0 for both values of x. We do as follows:


<span>h(x) = x^2 – 13x – 30
</span>h(3) = 3^2 – 13(3)– 30 = -60 <----------NOT ANSWER<span>

h(x) = x2 – 7x – 30
</span>h(3) = 3^2 – 7(3) – 30 = -42<----------NOT ANSWER<span>

h(x) = 2x2 + 26x – 60
</span>h(3) = 2(3)^2 + 26(3)– 60 = 36<----------NOT ANSWER<span>


h(x) = 2x2 + 14x – 60
</span>h(3) = 2(3)^2 + 14(3) – 60 = 0
h(-10) = 2(-10)^2 + 14(-10) – 60 = 0<span>

</span>

How many volleyball games would Rana
Fed [463]

Answer:

90 games

Step-by-step explanation:

Given: Total number of team (n) = 10

           Each team will play twice with each other.

We know that every team will play two game with each other except with itself, therefore each team will play (n-1)\times 2

⇒ Each team will play = (10-1)\times 2 = 18\ games

∴ Each team will have 18 games with each other in the league.

Now, as there are total 10 teams and each team have 18 games each, however, we have to make sure that no team have more than two games with other team.

Example: team_1 vs\ team_2\\\\team_2\ vs\ team_1\\

Both the above game are same and it is a mistake to take two different game.

∴ Total number of games played by all team= \frac{(n \times number\ of\ games\ played\ by\ each\ team}{2}

⇒ Total games = \frac{(10\times 18)}{2} = 90\ games

∴ Rana have to schedule 90 games in the Volleyball league.
