The underside of a bridge has a shape of a parabolic arch. It has a maximum height of 30m and a width of 50m. Can a sailboat with a mast of 28m above the water pass under the bridge 8m from the middle of the bridge?

  2. no I did not know I had to show my work,I did not read the posting tips, I have posted most of my work to show where I was stuck. I did not expect to have my homework just done for me as that would be useless when it came time to write the test or final exam. I am just not grasping how to interpret the word problems correctly into the quadratic equations, that is the part I am stuck on, not the actual equation. Does this make sense?
