Division sign?

÷ <--- use this one in the forum

and if you want to do division on this calculator, do a/b for \(a\div b\)

Do a^b for \(a^b\)

\( \dfrac{1}{2}(2x) + 1 = 1\\ x + 1 = 1\\ x + 1 - 1 = 1 - 1\\ x = 0\)

The horizontal distance between the two points is 950m ( starting at 2120m). A vertical line can be drawn from the 1650m point joining it to the horizontal line.

The length of the vertical line will be:      2120 - 1650 = 470

Since we are looking for the direct distance, consider it to be a diagonal line. The horizontal line, the vertical line and the diagonal will make a triangle. The lengths of the first two are already given, therefore we are only required to find the diagonal ( which is also the direct distance). This can be done using the Pythagoras Theorum.

                                 a^2 + b^2 = c^2

                         950^2 + 470^2 = c^2

                                  1123400 = c^2

           square root of 1123400 = c

                                   1059.91 = c  (2 dp)

3 - 3x

We find a number that can go into both 3 and -3. That number is 3, so we divide it into both of the numbers.

 Answer:   3 (1 - x)

It's ok Asad

No the real question is what kind of technology are you talking about? Pc? Stone age (thanks melody for answering the stone age question.) and even the lightbulb counts as tech. anything that is useful to us that was found could be technology please be more specific

It is about the advanced level of algebra after the first level it works more with exponents and NOT with normal 1+1 more like advanced shapes and if x₃₃ +2² then what is x depending on the state you live in.

mmm ok...

thanks for responding :)

Please can we explain your logic better guest ?

Hard - means different things to different people. You are imposing your own interpretation on this word.

I think perhaps that Hectictar has a more correct interpretation of what the asker may be meaning.

Asker .. you need to be more specific when you ask your questions. !

HARD is a meaningless word when you use it as you have.

(3.0)(0.612)+1/2(-9.81)(0.612^2)

This DOES NOT equal  0.459

3.0*0.612   +    1/2*-9.81*0.612^2

                  0.612^2 = 0.374544

=3.0*0.612   +    1/2*-9.81*0.374544

                 3.0*0.612 = 1.836

                  1/2=0.5

=   1.836   +    0.5*-9.81*0.374544  

=   1.836   +    -0.5*9.81*0.374544  

=   1.836   -    1.83713832

 = -0.00113832

check

(3.0)(0.612)+1/2(-9.81)(0.612^2) = -0.00113832

We are not here to do all your homework for you!!

Simplify $\frac{2\sqrt[3]9}{1 + \sqrt[3]3 + \sqrt[3]9}.$

\(\frac{2\sqrt[3]9}{1 + \sqrt[3]3 + \sqrt[3]9}\\Perhaps \ the \ reciprocal?\\\color{blue}\frac{{1 + \sqrt[3]3 + \sqrt[3]9}}{2\sqrt[3]{9}}= \frac{1}{2\sqrt[3]{9}}+\frac{1}{2\sqrt[3]{3}}+\frac{1}{2}\)

\(\frac{2\sqrt[3]9}{1 + \sqrt[3]3 + \sqrt[3]9}=1/( \frac{1}{2\sqrt[3]{9}}+\frac{1}{2\sqrt[3]{3}}+\frac{1}{2})\)

0.919916176948 !

yes (3-3x)= 3(1-x) so if you multiply 3 for 1 and -x you will have the 1st 

they should just go skinny dipping

OK thanks :D

i'm just getting used to equation with just TWO thingy LOL

There's no division sign in Trigonometry

\(\frac{\sin C}{20}=\frac{\sin 65^{\circ}}{19}\)

Multiply both sides of the equation by 20.

\(\sin C=20\,*\,\frac{\sin 65^{\circ}}{19} \\~\\ \sin C = \frac{20\sin 65^{\circ}}{19}\)

Take the arcsin of both sides of the equation.

\( C = \arcsin(\frac{20\sin 65^{\circ}}{19})\)

So...putting this into a calculator gives us

\(C\approx72.556^{\circ}\)

Becasue there is no   m^2   in  140n   

Thanks to my Mathematica 11 package !! By the way, using W/A also gives the same result ! Of course, W/A gets its results from Mathematica.
