An archer shoots an arrow up towards a target located on a hill, which is shown by the graph. Which set of equations best models the point of intersection of the arrow and the target?
y = –0.008x2 + 0.2x + 7 and y = 0.12x
y = 0.008x2 + 0.2x + 7 and y = 0.12x
y = –0.008x2 + 0.2x + 7 and y = x
y = –0.008x2 + 0.2x + 7 and y = –x

Respuesta :

The set of equations best models the point of intersection of the arrow and the target is:

y = –0.008x² + 0.2x + 7 and y = 0.12x.

What are the equations of the point of intersection?

To find the equations, we have to look at two things.

  • The coordinates of the point.
  • The behavior of the arrows trajectory, that is, if it's concave up or concave down.

The coordinates of the point are (35, 4.2), hence the best linear representation is:

y = 0.12x.

This leaves the first two options. The trajectory is concave down, which removes the second option, hence the correct option is:

y = –0.008x² + 0.2x + 7 and y = 0.12x.
