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.

The correct answer is D!!
Answer:
Step-by-step explanation:
The formula for determining the volume of a cone is expressed as
Volume = 1/3πr²h
Where
h represents the height of the cone
r represents the radius of the cone
π is a constant whose value is 3.14
From the information given
Radius = 5 centimeters
Height = 15 centimeters
Therefore,
Volume of cone = 1/3 × 3.14 × 5² × 15 = 392.5 cubic centimeters
