what is 2/3 of 108

2/3=0.125

0.125*108=13.5

11^2=121

2^2=4

121+4=125

what is -(x-5)^2

-(x^2+5^2-2*x*-5)

-(x^2+5^2+10x)

-(x^2+10x+25)

-x^2-10x-25=0

-x^2-5x-5x-25=0

-x(x+5)-5(x+5)

(x+5)(-x-5)

x+5=0   ,      -x-5=0

x=-5      ,      x=5

x=+or-5

2.5*0.4=1

answer is 1

better to know through internet.search for your question.

how do i find the IQR..........

well it is known to all ofcourse 2-2=0

tell me the best digital calculator plz...???

a ray of light approaches a jar of honey at an angle of 30 degrees. If the angle of refraction is 19.5 degrees. what is the refractive index?

Snell's law:sini/sinr

sin30/sin19.5

=1/2/0.333806859234

what is the equation of this line in slope intercept,standard,and point slope form.slope equals 2/5; point : (-1,3).?

let x₁=-1,   x₂=?,    y₁=3,   y₂=?

Point Slope Form:

y-3=2/5(x+1)

y-3=2/5x+2/5

2/5x-y+2/5+3=0

2/5x-y+3.4=0

answer must be checked

what is the equation of this line in slope intercept,standard,and point slope form. (0,1) and (3,0)?

answer:

let x₁=0,    x₂=3,    y₁=1,    y₂=0

formula is m = 

m=0-1/3-0

m=-1/3

Point Slope Form:

y-1=-1/3(x-0)

y-1=-1/3x

-1/3x-y+1=0

answer may be once check
