Caleb and a friend are throwing snowbals at a red bucket on a hill. The flight of a snowball can be modeled by the equation \( y=-0.02 x^{2}+x+4 \), where \( x \) is the horizontal distance and \( y \) is the height of the snowball in feet. The hill's slope can be modeled by the equation \( y=0.3 x-7.2 \). What is the approximate location where the red bucket should be placed? Justify your answer. 30. HTEM A sea lion dives off a rock into the ocean. Its path can be modeled by a quadratic equation lion's path: \( y=-0.5 x^{2}-x+6 \) where \( x \) is its horizontal distance traveled in feet and \( y \) is its elevation in feet with respect to the water. At the same time, a fish is swimming towards the surface on a path modeled by \( y=4 x-30 \). Where will the paths of the sea lion and fish mect? lustify your answer. 30.
