Answer:

Step-by-step explanation:
To make this a fraction, you do
. This is now a simple division problem. 4.5 ÷ 12 = .375
.375 as a fraction is
. When you simplify, you get 
Using derivatives, the rate of change of the mineral level with respect to time for 4 days is -0.012 mg/cm².
<h3>What is the missing information?</h3>
The function for the amount is missing, and is given by:

The problems asks for the rate of change of the mineral level with respect to time for 4 days.
<h3>What is the rate of change after 4 days?</h3>
The rate of change after 4 days is given by:
C'(4).
Applying the chain rule, the derivative of C(t) is given as follows:


When t = 4, we have that:


Applying properties of exponents, we have that:

Hence:

C'(4) = -0.012.
The rate of change of the mineral level with respect to time for 4 days is -0.012 mg/cm².
