Answer:
<h2>Ceramic does not foster bacterial growth</h2>
Step-by-step explanation:
A good way to think and reason deeply about this is, most if not all toilet bowls are made of ceramics, this is so because ceramics when it dries out kills all hanging bacterial on its surface, hence does not easily permit the growth of bacteria on its surface.
Another wonderful application of ceramic is in the application of water treatment process, specifically in the use as a water filter to kill bacterial, hence it is evident that ceramic does not permit the growth of bacteria
Answer:
15.7 meters
Step-by-step explanation:
Applying,
s = πd∅/360°..................... Equation 1
Where s = length of the arc formed, d = diameter of the circle, ∅ = angle formed by the center of the circle, π = pie.
From the question,
Given: d = 15 meters, ∅ = 120°
Constant: π = 3.14
Substitute these values into equation 1
s = (3.14×15×120)/360
s = 15.7 meters
Hence the lenght of the arc formed is 15.7 meters

Answer:
Step-by-step explanation:
7x^2 + x + 9 - (3x^2 + 4x- 5) =
7x^2 + x + 9 - 3x^2 - 4x + 5 =
4x^2 - 3x + 14
4x^2 - 3x + 14 - (4x^2 - 3x) =
4x^2 - 3x + 14 - 4x^2 + 3x =
