Slope is rise / run    or   (y2-y1) / (x2- x1)

Substituting:

slope =   1/4  =  (2-y)/(4-6) = (2-y)/(-2)

1/4 (-2) = 2-y

-1/2 -2 = -y

5/2 = y

26/9 = 2 remainder 8

rewrite 7 3/4 using radical notation

\({\large7} \ 3/4 \ or \ 7\frac {3}{4}=\frac{7\times 4+3}{4} =\frac{31}{4}=7.75\)

It actually says   asin   but that is short for arc sine which is the same thing as inverse sine :)

constant

(-5x - 8a) - (8a - 2x)

\(\begin{array}{|rcll|} \hline && (-5x - 8a) - (8a - 2x) \\ &=& -5x - 8a - (8a - 2x) \\ &=& -5x - 8a + (-1)\cdot (8a - 2x) \\ &=& -5x - 8a + (-1)\cdot 8a + (-1)\cdot (-2x) \\ &=& -5x - 8a -8a + 2x \\ &=& -5x + 2x - 8a -8a \\ &=& -3x - 16a \\ \hline \end{array}\)

tan(3) = x/10

x = 10 * tan(3)

x = 0.52407779283

It's just 1 divided by the variable/constant to the absolute value of the exponent

Example:

x^(-5) = 1/x^5

Good spotting Electric Pavlov :)

Is that meant to be a question ??

           40 = 0.56x - 5.4           |+5,4

    40+5,4 = 0.56x-5,4+5,4 

        45,4 = 0.56x                   | :0,56

45,4/0,56 = 0.56x/0.56

             x =81.07142856666....

Press the shift button and the one that says arcsin.

what is 12 divided by 1/8?

There is no largely accurate fraction representation of pi without having to use an infinitely large number of digits in both the numerator and denominator.  An approximation often used is 22/7, but a more accurate one would be 355/113.
13/4 
16/5 
19/6 
22/7 - Most commonly used in school.
179/57 
201/64
223/71

 

1,146,408 / 364,913

22/7

A slightly different approach:

(28 1/4 - 9 1/2 ) / 2 = 9.375 "       (9 3/8)

Well.......using feet, we have

5 yards  = 15 feet.....so the ratio   is  10 / 15  = 2/3

Uisng yards....10 ft  = 3 + 1/3 yards  = 10/3 yards...so we have.........[10/3] / 5   =  10/3 * 1/5 =  2/3

However....note...the ratios will be the same.....no matter which we use....!!!!

5 yards = 15 feet

10 feet : 15 feet =     2:3

Another possibility..... Most of the oil tanks I see around here in oil country sit on the ground....so if you had to paint the entire surface area, you would paint the side(s) and the top....

Top = pi x r^2 = pi x 3^2 = 28.274 m^2

The side(s) = pi x d x h = 245.044

Total=273.32 m^2

These are always a bit more puzzling than they should be, huh???

I'm assuming that the bar width = the door width

First.....divide 28 1/4 by  2   =   [113/4 ] /  2  =   113/8       (1)

Next....divide 9 1/2 by 2 =  [ 19/2 ] / 2   =  19/4 =  38/8     (2)

Subtract (2) from (1)    =   113/8 - 38/8  = 75/8  = 9 3/8 inches from the edge

Proof   [ 9  3/8 + 9 1/2 + 9 3/8 ]    = 113/4  = 28.25

ACTUALLY, you have it posted incorrectly....you left out the negative  AND  the -b part is also divided by 2a

x= (-b+-sqrt(b^2-4ac))/(2*a)

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