Lol to answer my own question I dont even get summer break!!! I move right into my next school year, but, I guess its for the best!

Sorry....I didn't   see the  (-)  in front of the  "0.5 "

Let me rework this.....it will be a similar process....

We can write

y = a( x + 0.5) ( x - 6.5)

And we know that   (0, 1)  is on the graph.....so

1 = a ( 0 +0.5) (0 - 6.5)

1  = a ( 0.5) ( - 6.5)

1  =  a (- 3.25)

a  =  -1 / 3.25   = - 4/13

So  our function  becomes

y = (-4/13) (x + 0.5) ( x - 6.5)

y = (-4/13) (x^2 - 6x - 3.25)

y =  (-4/13)x^2 + (24/13)x + 1

Here's the graph :  https://www.desmos.com/calculator/r3el9qubfe

Sorry about that   !!!!

We can use the tangent for this

tan (13°)  =   H / 58     where H is  the slide height....  multiply both sides by  58

58 *  tan (13°)  =  H  ≈  13 m    (rounded)

You worked it out much better than me, thank you!

However, the graph that shows in my textbook is actually a negative one with a max point rather than a mininal point as teh graph you showed me is :(

Also, how does 2x * 0,5 become 7x?

Glad for answers!

Bearing is measured clockwise from the North

Note that it is 100°,  measured counter-clockwise,  between the "North" line  and vector AB

So........ the bearing of B from A   =   360 - 100  =   260° 

Excuse me guest. Thats not very polite.

LEAVE HIM ALONE AND GET OUTTA HERE!!!!

You jerk! You have no right to call people names and if ya dont have an answer for a math question on a math forum I suggest you hit the road Jack.

We can write

y = a( x - 0.5) ( x - 6.5)

And we know that   (0, 1)  is on the graph.....so

1 = a ( 0 - 0.5) (0 - 6.5)

1  = a ( -0.5) ( - 6.5)

1  =  a ( 3.25)

a  =  1 / 3.25   =  4/13

So  our function  becomes

y = (4/13) (x - 0.5) ( x - 6.5)

y = (4/13) ( x^2 - 7x + 3.25) 

y = (4/13)x^2 -  (28/13)x  + 1

get off if your going to be rude 

Anytime Guest, anytime. 

And, if you dont wannna be a superstar, than dont be!!

You be what you want to be. You can be ANYTHING you want! People can't tell you who you are!! Their not you! But whatever it is that you want to be, be it. I  garuntee that with a little time, patience, hard work, and belief in yourself, you will have the career you've always wanted.
