She will then have 3 rings
Sin is opposite over hypotenuse, so sin(A) = 4/5. Cos its adjacent over hypotenuse, so cos(A) = 3/5
The function is increasing when the slope is greater than zero and decreasing when the slope is less than zero. Slope is (y2-y1)/(x2-x1) or the change in y divided by the change in x.
In this case the function is decreasing when x=[-8,-5) and when x=[4,8)
So in interval notation: x=[-8,-5)U[4,8)
it is 17
