24 + 4pi

This is because each side is 8 and the arc (using the perimeter of a circle formula) is 4pi.

Edited for perimter:
 3 sides at 8 yards each = 8*3 = 24 yards


 circumference of circle:  diameter x PI
   8 x 3.14 = 25.12

25.12 / 2 = 12.56

total perimeter = 24 + 12.56 = 36.56 yards  ( round answer as needed)

By how much does the dependent variable change in response to a change of 1 unit of the independent variable?
dalvyx [7]

Answer: C) 5

--------------

x = independent variable, y = dependent variable

Assuming this is a linear function, each increase of x by 2 leads to y going up by 10. So 10/2 = 5 is the unit increase each time x bumps up by 1.

-------------------

An alternative is to use the slope formula to get

m = (y2 - y1)/(x2 - x1)

m = (25 - 15)/(4 - 2)

m = 10/2 <--- this expression shows up again

m = 5 <---- leading to the same answer as before

So we see that the slope formula is a more drawn out method to finding the answer.
