Answer to Problem 12P
Explanation of Solution
Given information:
A logarithmic model is a function of the form
Many relationships between variables in the real world can be modeled by this type of function. The table and the scatter plot show the coal production (in metric tons) from a small mine in northern British Columbia.
Calculation:
Find the coal production when
Substitute
Hence, the required coal production at time
