Is the cordinates (2,4) (5,0) (6,8) (9,2) (11,6) functional?
Dmitrij [34]

Yes this is a function

The reason why is because the x coordinates do not repeat. Each x value maps to exactly one y value. For any input, there is exactly one output. If you were to graph all of these points, then the graph would pass the vertical line test.

If we had something like (2,4) and (2,0) then the input x = 2 would lead to multiple outputs (y = 4, y = 0) which would not make it a function; however we don't have any repeated x values here.

MrMuchimi

Answer:

48 goals

Step-by-step explanation:

From the attached image, we can see that:

Number of Home Goals = 9 + 6 + 8 + 7

= 30

Number of Away goals = 2 + 7 + 4 + 5

= 18

Total number of goals = 30 + 18

= 48

Sorry I don't have enough time to deal with this problems, I believe that by using this formula you will easily come out with your answer. In the first one that has all sides you must use the law of cosines. Here is the formulas . Keep it because it is very helpful
