Two goals post are 8m apart. A footballer is 34m from one and 38m from the other. Within what angle must he kick the ball if he
dmitriy555 [2]

Answer:

  11.06°

Step-by-step explanation:

The law of cosines can be used to find the angle. The sides adjacent to that angle are a=34, b=38, and the side opposite is c=8. Then the angle is found from ...

  c² = a² +b² -2ab·cos(C)

  cos(C) = (a² +b² -c²)/(2ab)

  C = arccos((a² +b² -c²)/(2ab))

  C = arccos((34² +38² -8²)/(2·34·38)) = arccos(317/323)

  C ≈ 11.06°

From the footballer's viewpoint, the goal posts are 11.06° apart.

Do the table and the equation represent the same function?
VARVARA [1.3K]
The table indicates a y-value of 115 when x = 0. That corresponds to the y-intercpt of the equation.

The table values increase by 64 for each increase of 2 in x-value. That corresponds to the slope (32) of the equation.

Yes, the equation and the table represent the same function.
