Answer:

- standard notation means in the number written in only number digits.

3.61 X 10^7 --> move 7 places to the right.

36100000

8.3 X 10^6 --> move 6 places to the right.

You start at (8, 0). You move right 2 units. Where do you end?

(10,0)

Step-by-step explanation:

Moving right 2 units will increase the x value by 2 since you are going further 'down the corridor'. Hope this helps.

As the limit of x goes to 3 from the left find the limit of (x/ sqrt x^2 -9)

Dimas [21]

$\displaystyle\lim_{x\to3^-}\frac x{\sqrt{x^2-9}}=\lim_{x\to3^-}\frac x{\sqrt{x^2}\sqrt{1-\frac9{x^2}}}=\lim_{x\to3^-}\frac x{|x|\sqrt{1-\frac9{x^2}}}$

Since $x>0$ , you have $|x|=x$ and the limand reduces to

$\displaystyle\lim_{x\to3^-}\frac1{\sqrt{1-\frac9{x^2}}}$

For $x>3$ , you have $\sqrt{1-\frac9{x^2}}>0$ since $\dfrac9{x^2}$ will always be smaller than 1, which means $\dfrac1{\sqrt{1-\frac9{x^2}}}\to+\infty$
