The expression y = 660(0.902)ˣ represents a decay , the rate of decrease is 9.8% .
In the question ,
it is given that ,
the the exponential function is y = 660(0.902)ˣ
we need to determine that , the equation represents a growth or decay .
0.902 is the variable that will determine a growth or decay .
Since, 0.902 is less than 1 , so it represents a decay function .
To find the rate we subtract 0.902 from 1
= 1 - 0.902
= 0.098
= 9.8% decrease rate
Therefore , The expression y = 660(0.902)ˣ represents a decay , the rate of decrease is 9.8% .
The given question is incomplete , the complete question is
Identify if it's Growth or Decay , and determine the percentage rate of increase or decrease , the function is y = 660(0.902)ˣ ?

Answer:
5 days
Step-by-step explanation:
This would have to do with average. So if one does it in 6 days and the other does it in 4 days, you would do the number between them. So 5 is between 4 and 6.
The more complicated way of thinking of it is like this...
add 6 and 4 6+4 that would = 10
Because we added two numbers, we have to divide by two.
10/2 which equals 5.
If it was numbers closer together like. 6 and 7 the middle numbeR would be 6.5 for example.
I hope this helped!!
Answer:
The ratio is 
Step-by-step explanation:
The volume of a cube with edge length a is:
We have two cubes:
Cube 1: The one with edge length of six inches.
Cubs 2: The one with edge length of one foot.
The ratio is:
In which 
is the volume of the first cube and 
is the volume of the second cube.
Volume of the first cube
The edge length is 6 inches, so 
.
Volume of the second cube
To express the ratio as a common fraction, both volumes must be in the same unit. So we must pass the edge length of the second cube to inches.
The second cube has edge length of one foot. Each foot has twelve inches. So
Ratio:
