Look dude....we don't need any of that c**p on here.......put a sock in it.......

Here is another one:

We need to find "r"

This is given by :

sqrt [ (-sqrt (3))^2  +  (7)^2 ]  =   sqrt ( 3 + 49)    = sqrt (52)

The way you have the tangent written,  y is negative and x is positive....

sin  =  y / r  =  -sqrt (3) / sqrt (52)         csc  =  r/ y =    -sqrt (52) /  sqrt (3)

cos  =   x / r  =  7 /sqrt (52)                  sec  = r / x  =    sqrt (52) /  7

cot =  x / y  =    -7/ sqrt (3)

180 (N - 2) N  = 170        multiply both sides by N

180 (N - 2)   =  170N     simplify

180N  - 360   =  170N         subtract  170N from  both sides....add 360 to both sides

10N   =  360           divide both sides by 10

N  = 36   (sides)

See the following image :

The center of the  incircle will be the intersection  of the angle bisectors shown

And the find the x coordinate of the center by solving these two equations :

y  = tan (135) [x -10sqrt(3)]       and  y  = tan(60) [x - 10sqrt (3)] + 10

Set these equations equal   and we have

tan (135) [x -10sqrt(3)]   = tan(60) [x - 10sqrt (3)] + 10       simplify

-1 [x - 10sqrt (3) ]   =  sqrt (3) [ x  - 10sqrt (3) ] + 10

10sqrt (3)  -  x   =  sqrt (3) x  - 30 + 10

x ( sqrt (3) + 1 )  =  10sqrt (3) + 20

x ( sqrt (3)  + 1)   =  10 [ sqrt (3)  + 2 ]

x =   10 [  sqrt (3)  + 2 ] / [ sqrt (3)  + 1 ]            multiply  top /bottom  by  sqrt (3) - 1     and we have

x  = 10 [  sqrt (3)  + 2 ] [ sqrt (3) - 1 ] /  [ 3 - 1]

x =  10  [  sqrt (3)  + 2 ] [ sqrt (3) - 1 ] /  [ 2]

x =  5 [ 3 + sqrt (3)  - 2]

x  =  5 [ 1 + sqrt (3) ]  =  5  + 5sqrt (3)

And the y coordinate of the center is :

And    y =   -1 [ 5 + 5sqrt (3) - 10sqrt (3) ]    =  -1 [  5 - 5sqrt (3) ]  =  5sqrt (3) - 5  =

5 [ sqrt (3)  - 1 ]       and this is the radius of the incircle

Reciprocal of n is 1/n:

Reciprocal of 0.0088 =1 / 0.0088 =113 7/11 

The answer is1/8

Follow P.E.M.D.A.S. (Parenthesees, Exponents, Multiplication, Division, Addition, Subtraction). Be sure to add, subtract, and all that jazz left to right!

Equation? 6 (-3) + 2 - 5

1) NO Parenthesees

2) NO Exponents

3) Multiply 6 (-3) = -18; -18 + 2 - 5

4) NO Division

5) Add -18 + 2 = -16; -16 - 5

6) Subtract -16 - 5 = -21

Following P.E.M.D.A.S, we get an answer of -21.

206.30

just about 206 times but i rounded up 

reciprocal of 0.0088

0.0088  =     88 / 10000

So....the reciprocal is        10000 / 88   =   1250  / 11

10x -14-12x+3  =  -25       combine terms on the left side

-2x - 11   = -25      add 11 to both sides

-2x  = - 14       divide both sides by -2

x  = 7

(6)*(-3)  +2 - 5       perform the multiplication, first

-18  +  2  - 5         now....just add and subtract from left to right

-16  - 5    =

-21

you do 10 + 6

then you add the d on the end

so it would be 

16d

thanks

2a^2   *  3a^5

Since we're just multiplying.....we can reorder this as

2 * 3 * a^2 * a^5             remember.........a^m * a^n  =  a^(m + n)....so we have

6 *  a^(2 + 5)   =

6a^7

actually dont worry ive done it

combine like terms.combine 0,064x and x. there is a 1 infront of the x that you can not see so what you will do is add the two you will get 0,065x + 0,09 . just remember that there is a ivisable 1 beforea x that is singular 

0.64x =  x + 0.09      it makes it easier  if you multiply through by  100....so we have

64x  = 100x  +  9        subtract 100x from both sides

-36x  = 9       divide both sides by -36

x   = -9 / 36   = -1/4

try dissconecting from your internet and count to about twenty-nine and that should do the trick if not then do not do it at home go to the libary
