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?

Answer 1

Did you read this before you posted your umpteen math problems?

"Homework Posting Tips

Please show your work. Tutors will not do your homework for you. Please show your work for any question that you are posting."

Answer 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?

Answer 3

Sorry Ms. Sue, I have posted hopefully correct or on the right track answers to all the other questions, but I have to go to sleep, I will attempt to answer this tomorrow Thanks
