What is the rate of change between the interval x= pi and x= 3pi/2
Romashka [77]

Answer:

\frac{6}{\pi } or 1.9099

Step-by-step explanation:

Look for y values at each of those given values of "x" and apply the slope formula.  When x = pi. y = -1 so the coordinate is (\pi,-1).  When x = 3pi/2, y = 2 so the coordinate is (\frac{3\pi }{2},2)

Plug those values into the slope formula:

\frac{2-(-1)}{\frac{3\pi }{2}-\pi}

You need a common denominator of pi:

\frac{3}{\frac{3\pi-2\pi}{2} }=\frac{3}{\frac{\pi }{2} }

Do the math on that to get a slope of \frac{6}{\pi } =1.9099
