Beyond the Answer
To find the width of the bunker at ground level, we need to determine where the front of the storage bunker intersects the ground, which is represented by
. We set the equation
equal to zero:
This implies that either
or
. Solving these, we find:
-
leads to -
leads to
The total distance between these two points is:
So, the width of the bunker at ground level is 144 inches.
To further verify, you could check that the function
equals zero at these points, reaffirming that they mark the width of the structure. Always remember, when you set a quadratic equation to zero, finding the x-intercepts will lead you right to the necessary dimensions!
