<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
When you have a negative exponent, you move the variable with the negative exponent to the other side of the fraction to make the exponent positive.
For example:
or 
(you don't move the "2" because "2" has an exponent of 1, only "y" has the negative exponent)
When you multiply a variable with an exponent by a variable with an exponent, you add the exponents together. (But you can only combine the exponents when the variables are the same)
(You can't combine them because they have different variables of x and y)
There's two ways you can do this. Either by first making all the exponents positive then do subtraction, or multiply them then make all the exponents positive. I'm doing the 2nd way.
You can combine the numbers 2 x 9 x 2 = 36
Now multiply the terms with the same variables
Now make all the exponents positive
If you were to do subtraction, here is what you need to know:
When you divide a variable with an exponent by a variable with an exponent, you subtract the exponents together. (Reminder: they have to be the same variable in order to combine the exponents)
For example:
or x
Answer:
17 seconds
Step-by-step explanation:
h(t) represents height, we want to know when the ball will return to a height of 28 feet. So our equation is..
28 = -2t² + 34t + 28
Now solve for t...
0 = -2t² + 34t (subtract 28 from both sides)
0 = t² - 17t (divide both sides by -2)
0 = t(t - 17) (factor out a t)
So
t = 0
or
t - 17 = 0
t = 17
0 seconds is the initial height. At 17 seconds, the ball will return to that height
