The center of an ice rink is located at (0, 0) on a coordinate system measured in meters. susan is skating along a path that can be modeled by the equation y = 6x – x2 – 5. luke starts at (10, –21) and skates along a path that can be modeled by a quadratic function with a vertex at (8, –9). if the rink is a circle with a radius of 35 meters, which statement best interprets the solution(s) of a system of equations modeling the paths of the skaters?
the skaters paths intersect once, but that point is outside the rink.
the skaters paths intersect once, and that point is inside the rink.
the skaters path intersect twice, but only one of those points is inside the rink.
the skaters paths intersect twice, and both points are inside the rink.

Gexpressions: practice question 3 of 5 jackson wants to study the popularity of his music video by tracking the number of views the video gets on his website. the expression below represents the total number of views that jackson's video receives n days after he begins tracking the nu views, where b is the rate at which the number of views changes. alb)" select the statement that would accurately describe the effect of tripling a, the initial number of views before jackson beginst the rate at which the number of views changes, b, will triple. the total number of views the video has after n days, a(b)", will not change. the total number of days since jackson begins tracking views, n, will be reduced by one-third. the total number of views the video has after n days, alb)", will triple. submit
