Avalanche researchers know that the temperature gradients within a snowpack are highly responsive to air temperature changes at the surface of the snowpack. These changing temperature profiles within the snowpack can result in the structural failure of existing weak layers. The researchers have collected data that measures the air temperature (in degrees Celsius) just above the snow surface over a period of 5 hours, where t=0 corresponds to noon on a particular day. The air temperature function is given by 1 T(t) t (3 – 2t)(2t – 5)²(t – 4) - a) In the data collection window, [0,5], when is the air temperature at freezing? b) In the data collection window, when is the air temperature above freezing (causing melt at the snow surface)? c) Sketch the function on the interval [0,5], using the information obtained above.

![B. Air Temperature
Avalanche researchers know that the temperature gradients within a snowpack are highly responsive to air
temperature changes at the surface of the snowpack. These changing temperature profiles within the
snowpack can result in the structural failure of existing weak layers. The researchers have collected data
that measures the air temperature (in degrees Celsius) just above the snow surface over a period of 5 hours,
0 corresponds to noon on a particular day. The air temperature function is given by
where t =
1
T(t) =t (3 – 2t)(2t – 5)²(t – 4)
a) In the data collection window, [0,5], when is the air temperature at freezing?
b) In the data collection window, when is the air temperature above freezing (causing melt at the snow
surface)?
c) Sketch the function on the interval [0,5], using the information obtained above.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff01ec549-4316-490c-aabd-8320804abc40%2F30e316d9-6f22-4859-9eb4-6877718244fa%2Fqyvs60g_processed.png&w=3840&q=75)
