Answer:
Decay
Step-by-step explanation:
Considering the model:
0.85=1-0.15
Therefore, the model can be rewritten as:
This shows that the model decays by a common ratio of 0.15 or 15%.
In general, when the common ratio is less than 1, the model decays while whenever it is greater than one, there is exponential growth.

Answer:
The area is approximately 453 ft²
Step-by-step explanation:
Area of a circle =
If = 22/7, and r = 12 ft
Area = (22/7)×12²
= 3.143*144
= 452.592 ft²
≈ 453 ft²
Answer:
(B , D) = (-2,5)
Step-by-step explanation:
The given quadratic expression is
compare the given expression with
so we have
now and
we need to find two numbers such that their product is -30 and sum is -1
-6 and 5 are such numbers
so we have
grouping first two terms and last two terms
factor out 3x from first two terms and 5 from last two terms
( factor out (x-2))
hence B =-2 and D= 5
(B,D)= (-2,5)
