Asked by Jack
Can someone show me the complete solution to this word problem?
William,a logistician,needs to route a freight train that is 20 feet at its tallest point and 10 feet at its widest point within 3 days. the most direct path includes a single-track tunnel that needs 24 hour notice prior to use. If the tunnel is roughly modeled by f(x)=-0.1x^2+3.2x-3.5,should William make arrangements for the train to use the tunnel? Show work that supports your conclusions.
