Question 1021939: An archway over a road is cut out of rock. Its shape is modeled by the quadratic function +y=-0.1x%5E2%2B12+ for y≥0.
A) Write an inequality that describes the opening of the archway.
B) Critical Thinking- Can a camper 6 ft wide and 7ft high fit under the arch without crossing the median line? Explain.

Your question A seems to be already answered in the description. You already know the equation because it is given. Just make into an inequality instead.

Question B:
The center under the arch at ground level receives 3 feet on one side of the camper vehicle and 3 feet on the other side of the camper vehicle; totalling 3+3=6 feet for the length. Evaluate y when x=3. Is y less than 7 or not less than 7 ?
