The graph below shows the height an elevator travels, y, in x seconds:

Answer:

25 (ft/s)

Step-by-step explanation:

The "rate of change" is taken to mean the "rise" divided by the "run". Here, adjacent points differ in their y-value by 25 ft and their x-value by 1 second.

The rate of change is ...

rise/run = (25 ft)/(1 second) = 25 ft/second

Usually, we're just interested in the numerical value: 25.

Additional comment

The graph is mis-labeled. It is not showing "rate of ascent." It is showing height as a function of time. The "rate of ascent" is the slope of the line on the graph, not its value.

if i I wanted to be precise, how can I express the exact circumference for the circumference given the diameter

sveticcg [70]

The formula for circumference is $\pi d$ .

To express the circumference exactly, plug the diameter in for $d$ and put the $\pi$ symbol in front of it. Don't multiply. This expresses the exact circumference.

Say you have the diameter of 17.
You can express the circumference with 17 $\pi$ .
