Write 0.0004571 in scientific notation.
NISA [10]
Scientific notation means to write the answer in standard form. standard form helps you to express numbers that are too big or too small to be conveniently written in decimal form.
so for this case, it will be 4.571×10^-4.
when the number is decimal, you move the dot to the right and it will always be multiplying 10 to the power of a negative power.

I am Lyosha [343]

Answer:

Using technology or other resources, research the average distance that each planet is from the Sun (in kilometers). Once you have found the distance, create a chart showing each planet's distance from the Sun. The Sun itself will not receive a label since it is your starting point. For example, Mercury is located an average of 57,909,000 km from the Sun, so on the chart, Mercury would be labeled with a distance of 57,909,000. Use the example of the chart below to help you get started:

Planet Distance from Sun (in Km) Distance in scientific notation

Mercury 57,909,000  5.7909 X10^7

Venus 108.212.290.56  1.0821229056 X10^8

Earth  149,604,618.24  1.4960461824 X10^8

Mars  227,936,640  2.2793664 X10^8

Jupiter  778,412,020  7.7841202 X10^8

Saturn   1,433,442,700.8  1.4334427008 X10^9

Uranus  2,870,972,200  2.8709722 X10^9

Pluto  5,906,380,000  5.90638 X10^9

Find slope of : parallel to 3y=2x+5
olga55 [171]

Answer:

The slope parallel to this line would be 2/3

Step-by-step explanation:

To find a parallel slope, start by finding the slope of the original line.

3y = 2x + 5

y = 2/3x + 5/3

So, we can see here that the slope is 2/3. Since parallel lines have the same slope, we know the parallel slope to also be 2/3
