The paths will cross when the coordinates are (1,9) and (4, 15).
<h3>What is a model?</h3>
A model is a representation of reality. Now we have that the path of the frisbee is y = -x² + 7x + 3 while the path of the dog is y = 2x + 7.
The both paths will cross when;
-x² + 7x + 3 = 2x + 7
-x² + 5x - 4 =0
x=1 or x=4
If x = 1, y = 2(1) + 7 = 9
If x = 4, y = 2(4) + 7 = 15
Thus the paths will cross when the coordinates are (1,9) and (4, 15).
