To Interpret: Whether the driver will react more quickly to a traffic light changing
from green to yellow or to the siren of an approaching ambulance based on the results
from parts
Yes, the driver will react more quickly to a traffic light changing from green to yellow or to the siren of an approaching ambulance.
Given information:
Given the expression,
Driver's reaction time to audio stimuli
Driver's reaction time to video stimuli
Explanation:
A driver is likely to react more quickly to the siren of an approaching ambulance based on our results from parts

- 9:41 … 93 Applying an Exponential Function to Newton's Law of Cooling 60. Water in a water heater is originally Aa ← 122°F. The water heater is shut off and the water cools to the temperature of the surrounding air, which is 60°F. The water cools slowly because of the insulation inside the heater, and the value of k is measured as 0.00351. a. Write a function that models the temperature T (t) (in °F) of the water t hours after the water heater is shut off. b. What is the temperature of the water 12 hr after the heater is shut off? Round to the nearest degree. c. Dominic does not like to shower with water less than 115°F. If Dominic waits 24 hr. will the water still be warm enough for a shower?
