Think about the commutative property of real number operations as it applies to addition and subtraction of functions how do you
kati45 [8]
The question does not make sense.
The commutative property applies to addition and multiplication, not addition and subtraction.
The commutative property does not apply to subtraction or division because in those operations, the order of the numbers makes a difference, whereas in addition and subtraction the order does not make a difference.

For example:

Addition
5 + 4 = 9
4 + 5 = 9
5 + 4 = 4 + 5
Changing the order of the 4 and the 5 gives the same answer.
The commutative property does apply to addition.

Multiplication 
5 * 4 = 20
4 * 5 = 20
5 * 4 = 4 * 5
Changing the order of the 4 and the 5 gives the same answer.
The commutative property does apply to multiplication.

Subtraction
5 - 4 = 1
4 - 5 = -1
5 - 4 is not equal to 4 - 5
Changing the order of the 4 and the 5 gives a different answer.
The commutative property does not apply to subtraction.

Division
5/4 = 1.25
4/5 = 0.8
1.25 is not equal to 0.8.
Changing the order of the 4 and the 5 gives a different answer.
The commutative property does not apply to division.

A professor is examining a new strain of bacteria. The amount of bacteria can be modeled by function s(n) = 20 · bn, where n is
user100 [1]
For this case we have a function of the form:
 y = A * (b) ^ n&#10;
 Where,
 A: initial amount
 b: growth rate (if b> 1)
 n: time in hours
 Substituting values we have:
 s (n) = 20 * b ^ n&#10;
 We have then that the initial amount is:
 A = 20&#10;
 If b = 1.85 then the growth percentage is:
 (1.85-1) * (100) = 85%&#10;
 Answer:
 
here were initially 20 bacteria.
 
The hourly percent growth rate of the bacteria would be 85%
