YAY!! So everytime that there is a negative in front of |x|, the answer will be a negative. Thanks, CPhill!!!!!!!

$${\mathtt{\,-\,}}{\frac{{\mathtt{8}}}{{\mathtt{9}}}}$$

Is it  $${\mathtt{\,-\,}}{\frac{{\mathtt{8}}}{{\mathtt{9}}}}$$ , or is it  $${\frac{{\mathtt{8}}}{{\mathtt{9}}}}$$ ?

Put parenthese around 10^16 first.

So, the question would look like this.

$${\mathtt{3.99}}{\mathtt{\,\times\,}}\left({{\mathtt{10}}}^{{\mathtt{16}}}\right)$$

Now, find the answer to the exponent.

$${{\mathtt{10}}}^{{\mathtt{16}}} = {\mathtt{10\,000\,000\,000\,000\,000}}$$

So, now you multiply. $${\mathtt{10\,000\,000\,000\,000\,000}}{\mathtt{\,\times\,}}{\mathtt{3.99}} = {\mathtt{39\,900\,000\,000\,000\,000}}$$

So,  $${\mathtt{39\,900\,000\,000\,000\,000}}$$  is our answer.

Hope it helps!

oKay. Can you help me on this one?

Finding Absolute Value Evaluate the expression.

Question 32)  $${\mathtt{\,-\,}}{\left|{\mathtt{\,-\,}}{\frac{{\mathtt{8}}}{{\mathtt{9}}}}\right|}$$

Please help me!

What is the difference??????????

And am I correct???????????

Is this the answer?

$${\mathtt{Velocity}} = -{\mathtt{17}}$$   $$feet per second$$ .

$${\mathtt{Speed}} = {\left|-{\mathtt{17}}\right|} = {\mathtt{17}}$$   $$feet per second$$ .

Thanks, Chris!! I just answer old questions that are unanswered. I saw that you and Melody use that type of method, and that's why I tried to use that method. But, thanks, CPhill!!!!!!!!!!!!

A parachutist descends at a rate of about 17 feet per second.

Question 8) What is the parachutist's velocity?

Question 9) What is the parachutist's speed?

Please help me.

So the answr to question 2 is  $$|x|=1/6=|-1/6|=-(-1/6)=1/6$$ .

Is that the way how you are supposed to do it?

Yes. It helps. 

Can you help me on something about absolute values too?
