Its  \(4.5/15 = 0.3\) m/s^2

x=2,5

You mean inverse tan? if so, then press the key at the top left hand corner that says "2nd", and use the key labled "atan".

when the acceleration is in opposite direction of the velocity it must be negative ?!! right or not ? 

1 nanometer=1 billionth of a meter, or 10^-9 meter, so 1.48nm is 1.48 X 10^-9 meters

Meat, because he's a butcher. His height is just a trick.

Alan, I still Don't understand.

what is n exponient 6 to the power of 6,

You mean something like this: (n^6)^6=n^36. By the way, the words "exponent" and "power" are the same thing.

n⁶ means n*n*n*n*n*n  i.e. there are 6 n's all multiplied together.

Since 30min = 0.5° this is sin(29.5°). Using the calculator on the home page we get:

yay

Meat!

Per cent increase = 100*(9.75 - 8.75)/8.75 % = 11.43%

Use s = u*t + (1/2)*a*t^2 where s = distance, u = initial velocity = -3 ft/s, t = 3 s and a = +2 ft/s²

i.e. acceleration is positive to the right as labby wrote.

Lol. u r k*****g me! 

K, k, i apologize. But u were being a bit rude. But it doesn't matter, cuz it's wht makes u fny. Lol. I think I'm gonna like tlkin 2 u. What shld the nxt tpc of our cnvrsation be? Prank wars?  Makin up fny stuff 2 insult each other? Btw, I love that fny cnvrsation were u guys were doing the popcrn n soda wars, halarious!

I love yr wrk. Jst saying, u r a riot! Ha!

If this is y = 3.....the y intercept is at (0,3)

the accelleration is positive

P = a + b + c     subtract a and b from both sides

P - a - b    =   c

I assume that the 5 less is supposed to be $5000 less...if so....

Let the 2009 cost be C  ....and we have.....

2C- 5000 = 25000     add 5000 to each side

2C = 30000    divide both sides by 2

C = $15000    = 2009 cost

the answer is 5

65km/hr =  325/18 m/s

70km/hr = 175/9 m/s   = 350/18 m/s

So in 10 sec.....the first car is 10 * 325/18 m  = 3250/18 m ahead of the other when the second car reaches the line

And we need to solve this

( 350/18 - 325/18) T =  3250/18       multiply both sides by 18

[350 - 325] T   = 3250

25T =  3250     divide both sides by 25

3250/25 = T =  130 seconds

Proof.......the second car closes the gap between the two vehicles by [25/18]m/s

In 130 s, the first car is 3250/18m ahead

So, in 130 s the second car makes up.....130* (25/18) =  3250/18 m  and closes the gap

An A*s!

To enter exponent on the calculator, press the labled "e" on the top, and enter the number that you want. To change the sign from + to -, press another key labled +-, on top of each other.

*car drives mega fast while being chased by the teachers for "playing war games"*

Time to distribute fire to the teaches

8-4[x-3-7(x-2)]

parenthesees!!!!

7*x=7x 

7*2=14

8-4[x-3-7x-14]

4*x=4x

4*3=12

8-4x-12-7x-14

now time to subtract and get rid of the bosses

8-12=-4-14=-18

4x-7x=-3x

overall, the answer is:

-18--3x
