Answer:
(-4,1)
Step-by-step explanation:
Ordered pair (-4,1) means that x = -4 and f(x) = 1
Ordered pair (1,-4) means that x = 1 and f(x) = -4
From the table, we can see that the function is already defined for x = -4, but it is not defined for x = 1. So, the point (1,-4) can be included into the function, but the point (-4,1) cannot.
42 runners total

of 42 (14) dropped out in first half.
42 - 14 = 28 remaining.

of 28 (16) dropped out in second half.
28 - 16 = 12 runners finished the race.
Area- 454.1 ft
how?- you can use a ratio to find diameter.
18/3= x/4 ft
x=24 ft
then find are by doing a=pi(3.14) times radius squared
a=p*144
a=452.4
