Each team in the softball league plays each of the other teams exactly once. If
Aleks04 [339]
<span>Each team in the softball league plays each of the other teams exactly once. For every game, there is 2 team playing. The order is not important because  A vs B is same as B vs A
So you just need to makes a combination of 2 that have a result of 21. If there is t number of teams, the number of matches would be:
tC2 = t!/2!(t-2)! = 21
</span>t! / (t-2)! = 21 *2
(t)(t-1)= 42
t^2 -t -42=0
(t-7)(t+6)
t=7 ; t=-6

Excluding the minus result, you got 7 teams.

Suppose that P is the point on the unit circle obtained by rotating the initial ray counterclockwise through 330 degrees. Find t
Flauer [41]

Answer:

Reference angle will be 30°

sin(330°) will be equal to \frac{-1}{2}

cos(330°) will be equal to 0.866

Step-by-step explanation:

We have given angle is 330°

As the angle 330^{\circ} is in forth quadrant

We know that in forth quadrant the reference angle is given by

Reference angle =360-angle

As the angle is 330°

So the reference angle will be =360-330=30^{\circ}

Now we have to find the value of

sin(330°) =sin(2\pi -30)=-sin(30)=\frac{-1}{2}

And now cos(330^{\circ})=cos(2\pi -30)=cos30=0.866
