Means the number you can use
remember we can't divide by zero
domain is x^2-9
set to zero to find values we can't use
x^2-9=0
x^2=9
x=+/-3
domain=all real numbers except -3 and 3
Answer:
circumfrence = 2 x pi x r
C = 2 x 3.14 x 3

Step-by-step explanation:
We know that
<span>A pitcher of water contains 1/4 liters of water--------------> 0.25 lt
then
0.25 lt/5--------> 0.05 lt
In each glass are 0.05 lt of water
1 lt-------------> 1000 ml
0.05 lt----------> X
X=0.05*1000--------> X=50 ml
the answer is
</span>In each glass are 0.05 lt of water
In each glass are 50 ml of water<span>
</span>
