<span>The ordered pair is (5000,12). This is given from the function a at x=5000, which is written in the question as a(5000)=12. Here, a is our dependent variable and is equal to 12. The x value, or independent variable is given as 5000. Ordered pairs are written (x,y) or (independent, dependent), thus the ordered pair is (5000,12).</span>

Answer:
7 packets of grass seed
Step-by-step explanation:
First, find the area of the circular lawn using the formula, A = r²
If the diameter is 20 meters, the radius is 10 meters.
Plug in 10 as the radius and solve for the area:
A = r²
A = (10²)
A = 100
So, the area of the lawn is 100 m² or approximately 314.16 m²
Divide this by 50 to find how many packets of grass seed are needed:
314.16/50
= 6.28
Round this up to 7, since we need to have a whole number answer.
So, 7 packets of grass seed have to be bought.
