Awheelchair ramp runs 36 inches and rises 3 inches. what is the rate of change?
a) 1/12
b) 12
c) 33
d) 39

A) 1/12

Step-by-step explanation:

We are told that a run of 36 inches corresponds to a rise of 3 inches.

The rate of change is generally calculate by taking the rise and dividing it by the run.

Here we have:

rate of change = rise/run= (3 inches)/(36 inches) = 1/12

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
