Suppose an x-y
axis is
superimposed on
cold front
the map with its
origin at des
moines, iowa. also suppose a cold front is passing through the united state
like a parabola with its vertex at des moines, lowa and a vertical stretch/shrink
states at noon having a shape roughly
and latitudinal distances are measured in hundreds of miles. see the figure abe
stretch/shrink factor of if both longitudinal
step 2: answers the following questions.
what type of function should be used to model the stom front? how did you know?
b) for the storm front shown in the figure above, is the leading coefficient positive or
negative?
how did you know?
d) keeping the x-y axis superimposed on the map with its origin at des moines, iowa, what is
the equation for the parabola that would represent the cold front?
step 3: state the answer to the following question and also explain the process by which you arrived at your
answer
if the cold front is moving south at 40 mph for 4 hours and retains its present shape, what would
be the equation of its graph at that time?
