Answer:
X + 10
Step-by-step explanation:
The formula for that represent the area covered by a marsh A(n) is .
An exponential decay is given by the function:
y = abˣ
Where a is the initial value of y, b is a constant which is less than 1, y, x are variables.
Since the area covered by a marsh, A, starts at 11500 acres, hence a = 11500. Since the area drops by 1/4 each year for n years, hence:
Therefore the formula for A(n) is

Answer:
3
Step-by-step explanation:
The highest degree amount or exponet amount is the power of a equation.
3 is the highest exponet so it is 3.
You could write 6/15 as a decimal 0.40.
Therefore .48>.40
R = -9
You subtract 8 from both sides, then divide both sides by 2 to get the value of r
