For the following exercises, explain the notation in words. The volume f(t) of a tank of gasoline, in gallons, t minutes after noon.

f′(30) = −20

Solutions

Expert Solution

Let the volume of a tank of gasoline (in gallons) at time t minutes after noon is f(t).

Consider the following:

f\'(30) = -20

This implies that the rate of change of volume of a tank of gasoline at t = 30, that is at 12:30p.m is equal to -20.

This means that the tank is losing 20 gallons of gasoline every minute at 12:30p.m.

An underground gasoline tank can hold 1.00x10^3 gallons of gasoline at 52.0 degrees F. If the tank is being filled on a cool morning when the outdoor temperature (and the gasoline in the tanker truck) is 32.0 degrees F, how many gallons from the truck can be poured in the tank? (b) Generally speaking, coefficients of thermal expansion of metals are two magnitudes smaller than that of gasoline's. If you would like to maximize the time or distance between gas...
