Area:

$36\pi - 72 \: cm {}^{2}$

Step-by-step explanation:

$( \frac{1}{4} \times \pi \times 12 {}^{2} ) - ( \frac{1}{2} \times 12 \times 12) = 36\pi - 72$

The number of basketball games that must be scheduled in a league with n teams is given by G(n) = (n2 - n)/2 where each team pla

Pani-rosa [81]

Answer:

There are 7 teams in the league

Step-by-step explanation:

Given that the number of games is given by:

$G(n) = \frac{(n^2-n)}{2}$

The equation will be used to determine the number of games. As we already know, that 21 games are scheduled which means G(n) is 21 so we have to find n when G(n) is 21

Putting this mathematically

$21 = \frac{n^2-n}{2}$

Multiplying equation by 2

$2*21 = 2*\frac{n^2-n}{2}\\42 = n^2-n\\n^2-n-42 = 0\\n^2-7n+6n-42 = 0\\n(n-7)+6(n-7) = 0\\(n-7)(n+6)=0\\n-7 = 0 => n=7\\n+6=0 => n=-6$

As the number of teams cannot be negative, the number of teams in league are 7.

Hence,

There are 7 teams in the league

lord [1]

Question is not written properly but i think you are looking for the table of given equation y=400-55x. So I will explain about how to get that.

number of hours can't be negative so that means x must be 0 or more.

like x=0,1,2,3,...

we just have to plug these x-values into above equation to find the y-value in order to calculate table.

I will show you calculation for x=2

y=400-55x=400-55*2=400-110=290

so the point in table will be (2,290)

similarly we can find more point and get final table as shown below:
