Step-by-step explanation:
In this problem we have a exponential function of the form
where
f(x) is the remaining mass of the element in grams
x is the time in minutes
a is the initial value (y-intercept of the exponential function)
b is the base
r is the rate
In this problem we have
---> is negative because is a decay's rate
substitute
The exponential function is equal to
For x=15 minutes
substitute in the function

Step-by-step explanation:
The area of a rectangle is length times width.
We divide the polygon into 4 rectangles:
The area of the first rectangle is :
The area of the second rectangle is
The area of the 3rd rectangle is
The area of the fourth rectangle is
Putting all together, the area of the polygon is;
0.16+1.44+1.6+0.4=3.6m²
