Answer:
Option B and D are represents the equation model exponential decay.
Step-by-step explanation:
Exponential decay function is in the form of : where a is the initial value and b≠0, 0<b<1.
Option A:
here a = 6 and b = 2.1 > 1
It is not an exponential decay
Option B
here a = 0.34 and b = 0.98<1
Therefore, It is an exponential decay.
Option C:
here a = 0.75 and b = 1.21 > 1
It is not an exponential decay
Option D:
here a = 8 and b = 0.28<1
so, it is an exponential decay.

Step-by-step explanation:
<u>Answer:</u>
The correct answer option is (21, 2).
<u>Step-by-step explanation:</u>
We are given the following two equations and we are to find the solution to this system of equations:
--- (1)
--- (2)
Since the left hand side of the both the equation is equal so we can equate the right hand sides of these equations equal to each other.
x = 21
Substituting this value of x in (2) to find y:
y = 2
Answer:no
Step-by-step explanation:
Well if 4 months is 178, 1 year would be 178 * 3. 3 years would be 3(178*3). The answer is C. 1602
