Answer:
n<1
Step-by-step explanation:
4n−5<−1
Add 5 to both sides.
4n−5+5<−1+5
4n<4
Divide both sides by 4.
4n/4<4/4
n<1
Considering the volume of the cylinder, it is found that Cai has collected 327.9 grams of trace element.
<h3>What is the volume of a cylinder?</h3>
The volume of a cylinder of radius r and height h is given by:
.
In this problem, we have that the radius and the height are given, respectively, by:
r = 9.3 cm, h = 17 cm.
Hence the volume of the cylinder in cubic centimeters is given by:
A water sample shows 0.071 grams of some trace element for every cubic centimeter of water, hence the amount of trace element is given by:
0.071 x 4619 = 327.9 grams.

Step-by-step explanation:
f(x) = -(x - 2)
=-(2-2)
=0
f(x) = -(x - 2)
=-(6-2)
