Vladimir hit a home run at the ballpark. A computer tracked the ball's trajectory in feet and modeled its flight path as a parabola with the equation, y = -0.003(x - 210)2 + 138. Use the equation to complete the statements describing

the path of the ball.

The vertex of the parabola is ✓ (210, 138)

The highest the ball traveled was ✓ 138 feet.

What does it mean by solve the exponential equation for x?

An energy drink company claims that its product increases students' memory levels. to support its claims, the company issues advertisements claiming that 8 out of 10 people (chosen randomly from across the country) who tried their product reported improved memory. the missing component in this study is a .

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)
