you to man

thanks guys

Hey Thanks I wish the same to you man

Hi Killersteve27,

If you want to put in a link just press the chain link button, the first on the left in the ribbon,

and then paste the web address into the box.

Is this a problem?

Try F(x) = e^(ax) and G(x) = e^(-bx) with a=b/(1+b)

Maybe this will help:

The bottom of the flag pole is point  A .

In every right triangle,  tan(angle)  =  length of opposite side / length of adjacent side. So....

tan( 50° )  =  10 / JA          Solve this equation for  JA  to get:          JA  =  10 / tan( 50° )

tan( 35° )  =  10 / SA         Solve this equation for  SA  to get:          SA  =  10 / tan( 35° )

JS  =  JA + SA                  Plug in the values we just found for  JA  and  SA .

JS  =  10 / tan( 50° )  +  10 / tan( 35° )

JS  ≈  22.67  meters

------------------------------

when do you know when to divide tan or when to bring the opposite or adjacent over to multiple?

Think about this problem:

8  =   16 / x     To solve for  x  , first multilply both sides by  x .

8x  =  16         Then divide both sides by  8  .

x  =  2

Similarly....

tan x  =   10  / D     To solve for  D  , first multiply both sides by  D .

D * tan x  =  10       Then divide both sides by  tan x  .

D  =  10 / tan x

Remember that  tan x  is just a number.

Okay so to find distance, we have to divide and to find length/height we have to multiple, correct?

a)    Distance along the floor, D, is given by

tan (10) =  60  / D      multiply both sides by D

D * tan (10)  =  60     divide both sides by tan (10)

D  =  60 / tan(10)  ≈  340 cm

b) Ramp Length, R

sin (10)  =  60 / R

R  =  60 / sin (10)  ≈  345.5  cm

Not really

Note that the tangent of an angle  is the opposite / adjacent

So.....consider the flagpole height the opposite side and the distance to the flagpole , D, is the adjacent side

So....

tan x  =   10  / D           multiply both sides by D

D *  tan x  =  10          divide both sides by tan x

D  = 10  / tan x

Does that make sense ??

1  =  sin  (5pi/4 -  d)

arcsin 1  =   arcsin  [ sin (5pi/4  - d) ]

pi/2   =  5pi/4  -  d

d  = 5pi/4  - pi/2

 d  = 5pi/4  - 2pi/4

d = 3pi/4  + n* 2pi       where n is an integer

1  =  sin [ 2 (pi -d)]

arcsin 1  =  arcsin  [sin [2(pi - d ) ]

pi/2   = 2 (pi - d)        divide both sides by 2

pi/4   = pi - d

d = pi  - pi/4

d  = 3pi/4  +  n * 2 pi      where n is an integer

I got a question... when do you know when to divide tan or when to bring the opposite or adjacent over to multiple? I'm confused on that and btw thanks

J and S are facing each other on opposite sides of a 10 m flagpole. From j pov the top of the pole is at an angle of elevation of 50 degree. From S pov is 35 degree. How far apart are j and S?

Note that, from J's point of view

tan (50)  = 10 / D1       where D1 is the distance J is from the pole

And from S's point of view

tan (35)  =  10 / D2        where D2  is the distance S is from the pole

So.....rearranging both......their distance apart is given by :

D1   +  D2  =

10/tan(50)   +  10/tan(35)    ≈  22.67 m

a) d= -86.0730091830127585

b) d= -41.8584073464102068

Solve for d:
1 = sin(d - π/4)

Reverse the equality in 1 = sin(d - π/4) in order to isolate d to the left hand side.
1 = sin(d - π/4) is equivalent to sin(d - π/4) = 1:
sin(d - π/4) = 1

Eliminate the sine from the left hand side.
Take the inverse sine of both sides:
d - π/4 = 2 π n + π/2 for n element Z

Solve for d.
Add π/4 to both sides:
d = 2 π n + (3 π)/4 for n element Z

Solve for d:
1 = sin(2 (π - d))

Reverse the equality in 1 = sin(2 (π - d)) in order to isolate d to the left hand side.
1 = sin(2 (π - d)) is equivalent to sin(2 (π - d)) = 1:
sin(2 (π - d)) = 1

Eliminate the sine from the left hand side.
Take the inverse sine of both sides:
2 (π - d) = 2 π n + π/2 for n element Z

Divide both sides by a constant to simplify the equation.
Divide both sides by 2:
π - d = π n + π/4 for n element Z

Isolate terms with d to the left-hand side.
Subtract π from both sides:
-d = π n - (3 π)/4 for n element Z

Solve for d.
Multiply both sides by -1:
d = (3 π)/4 - π n for n element Z

Where's please, child? (Kids these days, no manners.)

1. The distrubtor sells cars for 12 dollars each and Eric sells the cars for 20. 20 - 12 = 8. That's 8 dollars profit per car. The flea market booth fee is 50 dollars. (What a ripoff.) So that's -50 To start off with. 

D = Distrubtor cars.

S = Sales

(S - D) - 50 is the rule. (Clearication is needed, as I am can't do math so save my life.)

2. I am sorry, I can't do algebra.

3. Also algebra.

4. More algebra.
