Does tgx stand for tangent of x?

And Alexander. Behave yourself!

Hi All SmilesAlways,

Since you are dividing by 5x-6,

 $$5x-5\ne 0 \rightarrow x\ne 1$$

$$f/g=\frac{-20x^2+14x+12}{5x-6}\\\\
f/g=\frac{-2(10x^2+7x+6)}{5x-6}\\\\
f/g=\frac{-2(2x+1)(5x-6)}{5x-6}\\\\
f/g=-2(2x+1)$$

This is a line with a hole at (1,-6)

Domain All real x where x is not equal to 1

Range: All real y where y is not equal to -6

I am very tired so you need to check my working. 

A chord is an interval that touches goes from one point on the circumference of a circle to another point on the circumference of the circle.

just as our guest showed in the diagram. (The angle isn't important)

 $$SA=\pi r^2 + \pi r^2 + 2\pi rh$$

you can put the numbers in

$${\mathtt{2}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{-{\mathtt{9}}} = {\frac{\left({{\mathtt{6.67}}}^{{\mathtt{10}}}{\mathtt{\,-\,}}{\mathtt{11}}\right){\mathtt{\,\times\,}}{\mathtt{7.1}}{\mathtt{\,\times\,}}{\mathtt{7.7}}}{{{\mathtt{R}}}^{{\mathtt{2}}}}} \Rightarrow \left\{ \begin{array}{l}\end{array} \right\}$$

$${{\mathtt{R}}}^{{\mathtt{2}}} = {\frac{\left({{\mathtt{6.67}}}^{{\mathtt{10}}}{\mathtt{\,-\,}}{\mathtt{11}}\right){\mathtt{\,\times\,}}{\mathtt{7.1}}{\mathtt{\,\times\,}}{\mathtt{7.7}}}{\left({\mathtt{2}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{-{\mathtt{9}}}\right)}} \Rightarrow \left\{ \begin{array}{l}\end{array} \right\}$$

you can finish it on you hand calculator.

$$\frac{-M}{3}-7$$

$${\frac{{\mathtt{499.99}}}{{\mathtt{0.2}}}} = {\mathtt{2\,499.95}}$$

The minus is raised to the neg 3 as well! but -1*-1*-1=-1 so it doesn't make any difference to the answer.

Do they explain me root and power with properties in negative numbers? Example, when we have to make the power of a numer...

Take a look at this thread that I just put together for you.
