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: They will need 18 vans and $1,764.00 to rent the vans out.
Step-by-step explanation:
<em>140/8= 17.5 ( rounded 18)</em>
So in order to fit all students, you'll need 18 vans
<em>98.00* 8= 1,764</em>
<em>So the amount of money you'll need is $1,764.00</em>
So basically, since you know the equation and all of the dimensions, just plug in all of the numbers.
V =
r^2 h
V = 3 [the radius is diameter / 2] 4^2 * 12
V = 3 * 16 * 12
V = 48 * 12
V = 576
So there is 576 cm cubed of milk inside of the can.
(Whether it's filled to the brim, probably not.)
I hope I helped! :)
Answer:
Team's rowing speed in still water: 11.8 miles per hour.
Speed of the current: 3.4 miles per hour.
Step-by-step explanation:
Let r represent team's rowing speed in still water and speed of current be c.
Rowing speed with current would be and rowing speed against current would be .
We have been given that a rowing team rowed an average of 15.2 miles per hour with the current. We can represent this information in an equation as:
We are also told that rowing team rowed an average of 8.4 miles per hour against the current. We can represent this information in an equation as:
Upon adding equation (1) and (2), we will get:
Therefore, teams's rowing speed in still water was 11.8 miles per hour.
Upon substituting in equation (1), we will get:
Therefore, speed of the current was 3.4 miles per hour.
