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
Answer:
B
Step-by-step explanation:
The volume (V) of the prism is calculate as
V = lbh ( l is the length, b the width and h the height )
l = h = 4 × =
b = 3 × = 1, thus
V = × 1 ×
=
