A chemical processing plant must monitor a certain liquid substance in a batch of product they make. The substance is transferred from one tank into another in the manufacturing process and the rate of flow must be tracked. The function h(x) = 20(0.75)^x describes the height of the liquid in feet still remaining in the tank t minutes after the exit valve was tripped. a. Using the equation above, find the average rate of change in the height for the first 3 minutes. b. Estimate the instantaneous rate of change in the height at 5 minutes and illustrate this value on a graph. c. Interpret your answer to part b. within the context of the problem.

Question
Transcribed Image Text:A chemical processing plant must
monitor a certain liquid substance in a
batch of product they make. The
substance is transferred from one tank
into another in the manufacturing
process and the rate of flow must be
tracked. The function h(x) = 20(0.75)^x
describes the height of the liquid in feet
still remaining in the tank t minutes after
the exit valve was tripped.
a. Using the equation above, find the
average rate of change in the height for
the first 3 minutes.
b. Estimate the instantaneous rate of
change in the height at 5 minutes and
illustrate this value on a graph.
c. Interpret your answer to part b. within
the context of the problem.
