A ditch 2.5 m wide crosses a trail bike path. An upward incline of 15 (degrees) has been built up on the approach so that the top of the incline is level with the top of the ditch. What is the minimum speed at which a trail bike must be moving to clear the ditch? (Add 1.4 m to the range for the back of the bike to clear the ditch safely.)
I don't need the answer, just the work.

Alright, so today, I've been learning about oxidation numbers.

I find that they are very much like naming binary compounds etc.
However, in this molecular compound, I don't see how you can make it balance out with oxidation numbers. I mean, Chlorine needs to gain 1 electron to have a full outer energy level, and Phosphorus needs 3. Also, there aren't any rules that specify like fluorine what one of the oxidation numbers must be. I am quite stumped. If any background and explanation about this topic, and this question could be provided, thanks!

Two lines are parallel. Do the equations of those lines represent a consistent system, an inconsistent system, or a dependent system? How many solutions will such a system have? Why?

The First Ability I Have is to read anything with my eyes close. When i close my eyes and breath in and out i see a white blank space thier. And can see the outside world through the blank white space. Infact i told someone about the power and he didnt belive so he put a book in front of me and i closed my eyes breathed in and out and the white blank space came and i read a paragraph in the book. But i really have to concentraite my energy to do it. What is this called does anyone else have it
Another power i have is when im in bed or something and someone is walking around even without using th blank white space between my eyebrows i feel vibrations and know who it is. And i told someone of this ability i had when we were in school and wanted to test it so he asked me to close my eyes and he was going to tell someone to walk and he told me to tell him who it was. So i told him i would do it but i needed the whole class quiet so i can feel the vibrations and i felt them and them and

Anyone else know or heared of this strange ability who can i improve on it what is it called
