Answer:
Step-by-step explanation:
Here is a problem with the concept of properties of the exponent.
We are given 
and we have to find the value of 5x.
Now, 
{Since we are given that }
⇒ 
{Since we can write 
}
⇒ {Since we know the formula of exponent as 
}
(Answer)
72 because 12times 4 is 48 then 3/2 times 48 and that is 144/2 then divide it and 72
7x - 1 = 4x + 8
3x = 9
x = 9

7(3) - 1
21 - 1

4x + 8
4(3) + 8
12 + 8

3x - 17 + x + 40 + 2x - 5 = 180
6x + 18 = 180
6x = 198
x = 33
3(33) - 17
99 - 17
82
33 + 40
73
2(33) - 5
66 - 5

Answer:
C. y = Ae^(-(x-b)²/c)
Step-by-step explanation:
A is a model of exponential growth.
B is a model of exponential decay.
D is a "logistic function" model of growth in an environment of limited resources. It produces an "S" shaped curve.
The given bell-shaped curve can be described by the function of C, which decays either side of an axis of symmetry.
