Scientific notation of 325•10^-8

USPshnik [31]

Given:

A number is

$325\times 10^{-8}$

To find:

The scientific notation of the given number.

Solution:

Scientific notation of a number is the product of a number between 1 to 10 and 10 to the power some integer.

We have,

$325\times 10^{-8}$

It can be written as

$325\times 10^{-8}=3.25\times 10^{2}\times 10^{-8}$

$325\times 10^{-8}=3.25\times 10^{2+(-8)}$

$325\times 10^{-8}=3.25\times 10^{-6}$

Therefore, the scientific notation of the given number is $3.25\times 10^{-6}$ .

the equation of the line has form

y=kx+b

$\left \{ {{5=k*0+b} \atop {9=k*2+b}} \right. \\b=5\\9=2k+5\\2k=4\\k=2$ , so

$y=2x+5$

The second line is parallel to the first and runs 7 units lower, so b=5

$0=1k+5\\k=-5\\y=-5x+5$
