Engineers built an arch bridge across a river. The arch bridge makes a parabola shape that has the equation y=-0.1(x-5)^2+12, where x and y are measured in meters. if the bridge makes contact with both banks at a height of 4 meters how long is the distance between the two banks of the river where the bridge is? Round your answer to the nearest whole number.

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
