It can be plus or minus  that answer  :)

0.1cm×0.1cm=0.01cm²＝1mm²        

10mm×10mm＝100mm²=0.1cm²

It's same same an equation but different answer.

Because it is not the same question :)

10mm = 1 cm  not   0.1cm

this is of the form 

y=mx+b

m is the number in from of the x    (a part of the number is invisable, it is -1)

b is the y intercept.      :)

Calculate 3.31×108 times 4.1×106 by using scientific notation and the product rule. Express your answer in scientific notation

$$\\3.31*10^8 \times 4.1*10^6\\\\
=3.31*4.1*10^8 *10^6\\\\
=3.31*4.1*10^8 *10^6\\\\
=13.571*10^{8+6}\\\\
=1.3571*10*10^{14}\\\\
=1.3571*10^{15}\\\\$$

Which equation is in which form mat?

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

I guess I had best arbitrate.

Your working looks fine to me Mat.

You have not presented it in the three forms as requested but this is no big deal.  

Dragonlance needs to find some other food for his hogs.  :/

$$\\y-3=\frac{2}{5}*(x--1)\\
y-3=\frac{2}{5}*(x+1) \qquad $This is point slope form$\\\\
y=\frac{2x}{5}+\frac{2}{5}+3\\
y=\frac{2x}{5}+3\frac{2}{5}\qquad $This is gradient and y intercept form.$\\\\\\
5(y-3)=5(\frac{2}{5}*(x+1))\\
5y-15=2*(x+1)\\
5y-15=2x+2\\
0=2x-5y+2+15\\
2x-5y+17=0 \qquad $This is general form $$$

Matsunnymat you got all three of the slope and line equation problems wrong.

My mule would get at least one of these right.

This one is supposed to be point slope not point slop. I feed it to the hogs. Hogs like slop. Your other answers on here are slop too so hogs all get a big snack to night. hahahaha

How do I find the speed of an object relative to another object traveling away from it? 

If the 2 speeds are   6km/h and 4 km/h     then the relative speed will be  10km/h

This is simplistic but I think it is correct.   :)

$$45x^{-3}=\frac{45}{x^3}$$

Your statement makes no sense :/

The minus sign and the negative sign aee the same thing :)

This is a teaching and learning site mat.

You need to show people how you get your answers.

The explanation is much more important than the answer.   :)

Yes, I am aware that there may be a problem with the Gamma function.

I have let admin know :)

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

i think but not once check the answer

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

what is the equation of this line in slope intercept,standard,and point slope form. (-3,-2) and (1,6)?

ans: 

let x₁=-3,  x₂=1,   y₁=-2,    y₂=6

formula is m = 

m=6+2/1+3

m=8/4

m=2

Point Slope Form:

y+2=2(x+3)

y+2=2x+6

2x-y+4=0

answer may be:2x-y+4=0

answer is 238.5$

How do you multiply two different decimals to get the product 1

In general you cannot, because as you multiply decimals they become smaller & smaller;

For example .9 x.8 =.72 and if you squared the last number, you get even smaller numbers

That's .72 x .72=.5184.................and so on!
