(-1)/2, -(1/2), -1(-2) is the same thing as -1/2 as a whole. 

They are all the same thing...

ok! my question is under the acocunt summertastic101

Probabiliy = Desired Outcomes/All possible outcomes

1. All possible outcomes = 5

   Desired Outcomes = 1

So, the probability of losing a turn on the first spinner is 1/5

2. There is a 2/5 chance that you will either get a "Move Up" or "Move Right".

We cube 2/5 b/c we can't have use any other moves.

2/5 x 2/5 x 2/5 = 8/125

You try three yourself wih the information I have given you

Post it as another Q......I will help if I can....maybe someone else will....

thank you so much! can you answer 1 more question?

 f(x) = (x – 11)(x + 13)  =   x^2 +2x-143       the 'antideriviative'   is the same as the 'integral'

                                         1/3 x^3  + x^2 - 143x + c       This does not match the answers you have posted as choices (closest to third one) 

cos (2x) = cos^2 - sin^2     or      2 cos^2 x -1

sooo   2 cos^2 x  -1 = cos x

          2 cos^2 x - cos x - 1 = 0        let    x = cos x       then use quadratic formula to find x = 1 or - 1/2

cos x = 1 or -1/2     then from 0 to 2pi    this is      0    2 pi      and      2pi/3    4pi/3  

Average of 3    =  $ 15

so price is   3*15 = $ 45     then add   x

3*15   + x              and divide by 4 to get the average = $ 16

(3*15 +x)/4 = 16 

   solve for x = $ 19

Well, first of all    100 000 / 50 000 000  = =   . 00 2 

so  .002 > .93^86.63523174

so x = 85.635     TIME periods     each period is six hours

     * 6 = 513 .81 hours = 21.4 days

sqrt (2x-4) = 1 + sqrt(x+5)      square both sides

2x-4  = 1 + x + 5 + 2 sqrt(x+5)     simplify

x -10 = 2 sqrt (x+5)          square both sides

x^2 -20x+ 100 = 4x + 20      simplify

x^2 -24x+80 = 0          Factor ( or use quadratic formula)

(x-20)(x-4) = 0              x = 4   or 20         

volume=\(\frac43\)\(\pi\)\(r^3\)

so the answer is 12.348\(\pi\)

which is approximently 38.7923861

these are the options:

Both statements are true.

None of the statements are true.

Only the first statement is true.

Only the second statement is true.

A rate = B rate =   a

C rate = 12

1/12  + 1/a  + 1/a = 1/3     solve for a

2/a = 3/12

a/2 = 12/3

a = 24/3 = 8 hrs

disregard - i messed up 

The discriminant portion of the quadratic formula = 0 for just one answer

b^2 - 4ac = 0       a = 1    b = -m     c = (m-1)

m^2 - 4 ( 1)(m-1) = 0

m^2 - 4m + 4 = 0                                quadratic formula shows m = 2

Expand R equation

x^2 + 2xy + y^2 = 121     sub in first equation

x^2 + y^2 + 2xy = 121

(61) + 2xy = 121

xy = 30                                          6 and 5 come to mind

so it is the equation 50000000*(0.93)^x<100000 so the answer is 23 becuase 100000/50000000 is about 0.02 and 0.02 is greater then 0.93^23 and the answer is \(23\)

Arrange line equation in the form   y = mx + b      m is the slope

y = -1/5 x+1     slope = -1/5     perpindicular slope = - 1/m = 5

y = 5x + b     sub in the point given to find 'b'

-3 = 5(2)+b

b = -13

y = 5x-13

Use Quadratic Formula

\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)      a = 1    b=2    c= 5

\(x = {-2 \pm \sqrt{2^2-4(1)(5)} \over 2(1)}\)    =   .....................

 It will drop the 10 m    then it will become a geometric sequence

     10  + 10  + 5  + 2.5    etc  

   10 + geometric sequance    a1 =10   r = 1/2

sum of geometric sequence = a1 (1/(1-r))

                                             = 10 (1 /1/2)  = 20

10 + geometr seq sum =   10 + 20 = 30 m

In 20 minutes the helicopter will be    90 m/hr * 1/3 hr = 30 miles from origin

the x component will be   30 miles * cos 250

the y component will be   30 miles * sin 250 =........... miles

-(1/2) = (-1)/2 = 1/(-2) = -1/2

  I think you have to look at the worst case scenario

  You COULD draw  13 red in a row, then 10 yellow in a row..... before drawing a third color  : green or blue

           so to ENSURE three clolors you will need to draw 13 + 10 + 1 =  24 draws

we start by seperating the hexagon into 6 equalateral triangles with area 1 then you find the base is 2 and 2 halve of the base of the triangle which is 3 base of the triangle and the height is one side of the triangle for the hypotenuse and half of a side off the triangle for a base.
