BQ: A toy water cannon at a water park sprays water along a path modeled by the equation h=-0.3x^2 + 4.2x + 3, where x is the horizontal distance (in feet) of the water from the cannon and h is the corresponding height (in feet) of the water. What is the maximum height that the water spray reaches?

A. 16.5feet
B. 17.7feet
C. 18.9feet

No, you do *not* "need the steps and explanations in solving" those questions. Show your work/attempts and/or pertinent questions here *first* so that you may be helped where you are stuck. I am also sending you a private message, because you're off on the wrong foot with your expectations. Read the suggestions at this link about posting: http://www.freemathhelp.com/forum/threads/41536-Read-Before-Posting!!

\(\displaystyle \ \ \ \) \(\displaystyle \ \ \ \) Determined, you were told not to carry on this wrong posting behavior! And as you read the posting rules, you would know not to post more than one problem and to show your attempts here first. If you're not going to follow those, then do not make any posts. Edit:

Excuse me?​

Determined, you should not be asking "excuse me" to me. You should be stating it (as in you are sorry to me.)

Hello Determined,

You are going to find that this is pretty much standard at all respectable math help sites. When you post a bunch of problems with no effort shown, it comes across as you wanting your homework to be done for you. This behavior is usually discouraged.

The people who volunteer their help at the sites are glad to do so, but know the student gains very little if problems are just worked for them. If you post your work/attempt, or even just what theorems you think may apply, then people are happy to guide you, or help you determine why what you are trying is not working.

Best Regards,

Mark.
