Answer:

20\pi

Step-by-step explanation:

Let the radius of the disk be r centimeters. Since the area of the disk is 100pi sq cm, we have \pi r^2=100\pi, and since r is positive, r=10. The circumference of a circle is 2\pi r, which, in this case, is \boxed{20\pi}.

The table represents a linear function.<br> What is the slope of the function?
TEA [102]

Answer:

-4

Step-by-step explanation:

The function is linear; therefore, the slope of the line joining any two points is the same.

We take any two points from the table and compute the slope or  rise/ run between them— let is take points (-4, -2) and (-2, -10).

The slope m of the line joining the points is

m=\dfrac{\Delta y }{\Delta x } =\dfrac{-2-(-10)}{-4-(-2)} \\\\\boxed{m=-4}

The slope of the function is -4.
