(a) Estimate the minimum temperature and the time at which it occurs.
The minimum temperature is i
! 'F and it occurs at
i
:
A.M.
Temperature (°F)
Transcribed Image Text:(b) The temperature rise is fairly linear from 8 A.M. to 2 P.M. Estimate the rate at which the temperature is increasing during this time
period.
Round your answer to one decimal place.
The temperature is increasing at a rate of i
°F/h
(c) Estimate the time at which the temperature is increasing most rapidly. Estimate the instantaneous rate of change of temperature
with respect to time at this instant.
Round your answers to the nearest integer.
The temperature is increasing most rapidly at i
The instantaneous rate of change at this instant is
i
°F/h.
