A beach ball rolls off a cliff and onto the beach. The height, in feet, of the beach ball can be modeled by the function h(t)=64−16t^2, where t represents time, in seconds.

What is the average rate of change in the height, in feet per second, during the first 1.25 seconds that the beach ball is in the air?

hi there

the slope is 1/3.

this is because from the y-intercept, you go up one, and you go to the right three, to get to the next exact point on the graph. this is known at the “rise over run.”

p.s. (if you need it).your y-intercept is -2, because that is the point on the graph where the line crosses the y-axis.

hope that : )

his answer is incorrect. i just used it, and it said it was incorrect. the answer is 0.
