Match each number in scientific notation with the number written in standard form and in a step by step process.

geniusboy [140]

Answer:

1) Option 3

2) Option 1

3) Option 2

Step-by-step explanation:

To find : Match each number in scientific notation with the number written in standard form and in a step by step process.

Solution :

From scientific to standard we expand the power of 10.

1) $6.82\times 10^7$

Remove decimal and open the power,

$6.82\times 10^7=\frac{682}{100}\times 10000000$

$6.82\times 10^7=68200000$

Therefore, $6.82\times 10^7=68,200,000$

Match with Option 3.

2) $6.82\times 10^{-6}$

Remove decimal and open the power,

$6.82\times 10^{-6}=\frac{682}{100}\times \frac{1}{1000000}$

$6.82\times 10^{-6}=\frac{682}{100000000}$

Therefore, $6.82\times 10^{-6}=0.00000682$

Match with Option 1.

3) $6.82\times 10^6$

Remove decimal and open the power,

$6.82\times 10^6=\frac{682}{100}\times 1000000$

$6.82\times 10^6=6820000$

Therefore, $6.82\times 10^6=6,820,000$

Match with Option 2.

What is 20-30+40x11-12+13-1000=??? can you get it ????<br> you will get 50 pints for geting it

AleksandrR [38]

Answer:

-569

Step-by-step explanation:

$20 - 30 + (40)(11) - 12 + 13 - 1000$
$-10 + (40)(11) - 12 + 13 -1000$
$-10 + 440 - 12 + 13 -1000$
$430 - 12 + 13 - 1000$
$418 + 13 - 1000$
$431 - 1000$
$-569$

What is the equation of the line that passes through the point (-2,0) and has a slope of -2

Tcecarenko [31]

Answer:

y = -2x -4

Step-by-step explanation:

The equation of a line is y = mx + b, where m is the slope of the line, and b is the y-intercept. We are told that the slope of the line is -2, so we can start with

y = mx + b

y = -2x + b

We can figure out the value of b by plugging in the coordinates of the point given (-2, 0)

0 = -2(-2) + b

0 = 4 + b

Subtract 4 from both sides of the equation

-4 = b

Then plug that value of b back into the equation above:

y = -2x + (-4) or y = -2x -4

HELP PLEASE: Which is the equation of the graphed line written in

maksim [4K]

Answer:

$x - y = 0$

Step-by-step explanation:

Required

The graph equation

From the graph, we have:

$(x_1,y_1) = (0,0)$

$(x_2,y_2) = (1,1)$

The slope of the graph is:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{1-0}{1-0}$

$m = \frac{1}{1}$

$m =1$

So, the graph equation is:

$y = m(x - x_1) + y_1$

$y = 1 * (x - 0) + 0$

$y = 1 * x$

$y = x$

In standard form, we have:

$x - y = 0$
