What is the rate of change between the interval of x = 0 and x = pi over two?

bekas [8.4K]

Answer:

The answer is $\frac{4}{\pi }$

Step-by-step explanation:

Given the graph as shown, we have to find the rate of change between the interval of x=0 and $\frac{\pi }{2}$ .

To find the rate of change we have to find the slope which is given by

$Rate\thinspace of \thinspace change=slope=\frac{change\thinspace\thinspace in\thinspace\thinspace y\thinspace\thinspace coordinate}{change\thinspace\thinspace in \thinspace\thinspace x \thinspace\thinspace coordinate}$

= $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

= $\frac{5-3}{\frac{\pi }{2} }$

= $\frac{4}{\pi }$

So a line is 180 degrees. These angles would equal 180. So 180= w + (3w -28). You add 28 too 180, getting 208. Then divide by the 4w. Leading you to w= 52. Plug into the equations to make sure everything checks out
