Question 178985
Use the following equation, where x and y are measured in meters, 
to model a cross section of the Barrenger Meteor crater, 
near Winslow, Arizona.
:
Barringer meteor crater model: y ={{{1/1800}}}(x-600)(x+600)
:
what is the depth of the crater?
:
y = {{{(x^2 - 360000)/1800}}}
:
y = {{{(x^2/1800)}}} - {{{(360000/1800)}}}
:
y = {{{(x^2/1800) - 200}}}
:
difference of squares so axis of symmetry is 0 and the minimum = -200
:
Like this
{{{ graph( 300, 200, -700, 700, -250, 100, x^2/1800 -200)}}}
:
Crater is 1200 ft wide and 200 ft deep
