Question by alwazsk8in09: the height of a kite above the ground is nine feet more than the distance from the person flying the kite to?
a point directly below it. the length of the string to the kite is 45 feet. how high is the kite?

Best answer:

Answer by Mr S
It’s a right triangle. Hypotenuse 45 ft, base X, height X+9.

X^2 + (X+9)^2 = 45^2
2X^2 + 18x – 1944 = 0
X = 27 (Quadratic formula)

Height = X + 9

36

Question by Hasnain I: A girl flies the kite at the height of 300ft, the wind carry the kite horizantally away at a rate of 25ft/sec?
A girl flies the kite at the height of 300ft, the wind carrying the kite horizantally away at a rate of 25ft/sec?
How fast she must let out the string when the kite is 500 ft away from her?

Best answer:

Answer by phantom_man17
the string length L
Horizontal distance H
Virtical distance constant = 300
L = (300^2+H^2)^1/2
H = 25t
L = (90000+625t^2)^1/2

but at L =500
H = 400
t = 400/25=16

dL/dt = 1/2 *(90000+2*625t)/(90000+625t^2)^1/2
= 1/2*(90000+2*625*16)/(90000+625*256)^1/2
= 110 feet/second

Open Your Eyes


Image by Sleep Underground Tonight
By Ryan Johnston -

Outside the front door
The gravel path is soaking up
The last of this season’s warmth
I’m alive, inside these walls
And this place, is where I live

So many days have been,
So many nights will come,
Will there be something left of me?
Will you still be there for me?
Today, I think you will be

But I think we both know
That it just never falls the same
And I think I might rather go without
Because if I see anymore change
Or lose one more truth right now
Then I think I might walk away
And miss the ending

Burning paper days
Dragging heavy hearts
Spinning riddles and webs
The answers, stuck inside my head
Counting on, some kind of safe bet
If anything, you just trick yourself

Letting go of weight
Falling down too quick
Taking longer than I ever thought
To get back on my own, again
Filling up what’s left of me
With something that I’ve never been
If anything, it’s only truth you find

Irrigate your regret
With poison water from that lake
It’s only hell, that you’ll cultivate
Deep like the bones that never rest
This is what I’ve grown
This is what I have become
If anything, I wish we had more time

The path outside
Turns, and leads to a ledge
At night, I would sit out on this rock
Thinking of the mess I’d made
And how hard it’s been
To keep my balance, while I’m falling
I know now, that you liked me
With both of my feet on the ground

Across from me, the highway roars
like a dark ocean, it echoes
The only constant,
I’ll probably ever know
Giving everything,
You end up with nothing
I guess it only makes sense
In the night sky,
The stars go on, and on
I’d give anything
To Keep this all from dying

I’m alive inside these walls
This place is where I’ll live
I’m anchored to a severed rope
A kite without a string
Sink alone, to the ocean floor
Ripped away, in the summer wind

“With you hand holding tight to the string of your kite …”

Like a giant metallic kite… Just hold onto the yellow string.
