This might just be:

$$x^2+Px+Q=0$$

in which case:

$$x=\frac{-P\pm \sqrt{P^2-4Q}}{2}$$

.

You can't is the simple answer....................

Just type this directly into the calculator (using parentheses for the trig arguments):

$${\mathtt{2}}{\mathtt{\,\small\textbf+\,}}{\mathtt{451}}{\mathtt{\,-\,}}{\mathtt{52}}{\mathtt{\,\times\,}}\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{sin}}{\left({\mathtt{30}}^\circ\right)}{\mathtt{\,\times\,}}{cot}{\left({\mathtt{10}}\right)} = {\mathtt{305.546\: \!672\: \!690\: \!029\: \!848\: \!8}}$$

.

453-(52*(sin(30)xcot(10)))

1 whole=100%  in which this case we have 2 wholes=200%

1/2 whole=50%

200%

+50%

=

250%

If you choose 2nd const you get a menu with some in-built constants (that you can select by typing first few letters). 

However, neither solar mass nor solar radius are there, I'm afraid!

.

I don't know much about the calc maybe someone else can help you.  

ALAN is ususally a wealth of information.

Thanks Voodox for that great answer.

Anon:

You have now had this exact question answered on 2 different posts. - please do not double post like this. 

inverse tan is the same as arc tan so just use

[2nd]  atan

MAKE SURE THE BUTTON AT THE BOTTOM IS SET TO DEGREES OR RADIANS - THE ONE YOU WANT OF COURSE.    :)

3/4 + x/8 = 1 so

6/8 + x/8 = 8/8

Multiply both sides by 8

Thereby: 6 + x = 8

Answer:  x= 2 

$$\\\frac{3}{4}+\frac{x}{8}=1\\\\
\frac{x}{8}=1-\frac{3}{4}\\\\
\frac{x}{8}=\frac{1}{4}\\\\
x=\frac{1}{4}\times 8\\\\
x=2$$

You cannot solve this because there are 2 variables.  You need 2 equations to solve for 2 variables.  

(x-y)*(x-y)

= x*x + x*(-y) + x*(-y) + (-y)*(-y)

= x^2 - 2*x*y + y^2

 (X-Y) (X-Y) =X^2-2XY+Y^2

Here's a tree diagram:

The antilog of 2.4 is 10^2.4

$${{\mathtt{10}}}^{{\mathtt{2.4}}} = {\mathtt{251.188\: \!643\: \!150\: \!958\: \!011\: \!1}}$$

Check:

$${log}_{10}\left({\mathtt{251.188\: \!643\: \!150\: \!958\: \!011\: \!1}}\right) = {\frac{{\mathtt{12}}}{{\mathtt{5}}}} = {\mathtt{2.4}}$$

.

Is that what you are feeling like today anon?    :(

$$\begin{array}{rll}
\frac{5n}{2}&=&\frac{8}{(3n-24)}\\\\
2(3n-24)\times\frac{5n}{2}&=&\frac{8}{(3n-24)}\times2 (3n-24)\\\\
(3n-24)\times5n&=&8\times2\\\\
15n^2-120n&=&16\\\\
15n^2-120n-16&=&0\\\\


\end{array}$$

$${\sqrt{{{\mathtt{120}}}^{{\mathtt{2}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{4}}{\mathtt{\,\times\,}}{\mathtt{15}}{\mathtt{\,\times\,}}{\mathtt{16}}}} = {\sqrt{\left({\mathtt{16}}{\mathtt{\,\times\,}}{\mathtt{4}}{\mathtt{\,\times\,}}\left({{\mathtt{15}}}^{{\mathtt{2}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{15}}\right)\right)}} = {\mathtt{8}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{240}}}} = {\mathtt{16}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{60}}}} = {\mathtt{32}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{15}}}}$$

$$\\n=\frac{120\pm32\sqrt{15}}{30}\\\\
n=\frac{60\pm16\sqrt{15}}{15}\\\\$$

35/100*x=70

multiply both sides by 100/35

(100/35)*(35/100)x=70*100/35

x=200

some of your question is missing - I might be able to fill in the dots :)

y=mx+c

52 = -1.75(32) + c

52 = -56 + c

add 56 to both sides and you get

52+56=c

c=108

y=-1.75x+108

here is your graph
