There are usually 16 games in a football season.
Since there's three more games, they've had 13 so far.
There are 27 combinations of outcomes.
P=44+66+88/2=198/2=99
With Heron formula:
S=root 99*(99-44)(99-66)(99-88)=root 99*55*33*11=root 1976535= 1405.8929.....=1405.9
Answer:
The triangle of the 360 squared by the square
Answer:
The correct option is A.
Step-by-step explanation:
If a line passes through two points
and
, then the equation of line is
![y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%28x-x_1%29)
Let y be the profit (in millions) after x years.
From the given graph it is clear that the line passes through the point (1,-100).
The company paid for these costs and made combined profits of $80 million after 4 years. It means the graph passes through the point (4,80).
The line passes through (1,-100) and (4,80). So, the equation of line is
![y-(-100)=\frac{80-(-100)}{4-1}(x-1)](https://tex.z-dn.net/?f=y-%28-100%29%3D%5Cfrac%7B80-%28-100%29%7D%7B4-1%7D%28x-1%29)
![y+100=\frac{180}{3}(x-1)](https://tex.z-dn.net/?f=y%2B100%3D%5Cfrac%7B180%7D%7B3%7D%28x-1%29)
![y+100=60(x-1)](https://tex.z-dn.net/?f=y%2B100%3D60%28x-1%29)
![y+100=60x-60](https://tex.z-dn.net/?f=y%2B100%3D60x-60)
Subtract 100 from both sides.
![y+100-100=60x-60-100](https://tex.z-dn.net/?f=y%2B100-100%3D60x-60-100)
![y=60x-160](https://tex.z-dn.net/?f=y%3D60x-160)
The function form is
![f(x)=60x-160](https://tex.z-dn.net/?f=f%28x%29%3D60x-160)
Therefore, the correct option is A.
