In the game of cornhole, when Sasha tossed a bean bag to the edge of the hole, in which the equations of the hole and bean bag's path are x² + y² = 5 and y = 0.5x² + 1.5x - 4, respectively, she could have tossed her bean bag to the points (1, -2) or (2, 1).
To find the points in which she could have tossed her bean bag, we need to intersect the two equations of the function as follows.
The equation for the hole
[tex] x^{2} + y^{2} = 5 [/tex] (1)
The equation for the path of the bean bag
[tex] y = 0.5x^{2} + 1.5x - 4 [/tex] (2)
By entering equation (2) into (1) we have:
[tex]x^{2} + (0.5x^{2} + 1.5x - 4)^{2} = 5[/tex]
[tex]x^{2} + 0.25x^{4} + 1.5x^{3} - 4x^{2} + 2.25x^{2} - 12x + 16 = 5[/tex]
[tex]0.25x^{4} + 1.5x^{3} - 0.75x^{2} - 12x + 11 = 0[/tex]
By solving for x, we have:
x₁ = 1
x₂ = 2
Now, for y we have (eq 2):
- x₁ = 1
[tex] y_{1} = 0.5(1)^{2} + 1.5(1) - 4 = -2 [/tex]
- x₂ = 2
[tex] y_{2} = 0.5(2)^{2} + 1.5(2) - 4 = 1 [/tex]
Therefore, the points are (1, -2) or (2, 1).
