Model 3: Another plan to secure the roller coaster involves placing two concrete struts on either side of
the center of the leg of the roller coaster to add reinforcement against southerly winds in the region.
Again, using the center of the half-circle as the origin, the struts are modeled by the equations
y=-x+8 and y=-x-4. A vertical reinforcement beam will extend from one strut to the other when
the two cables are 2 feet apart.
8. Graph the two struts on the model of the roller coaster. Take a screenshot of your graph and
paste the image below, or sketch a graph by hand. (5 points)
