Hi I need help,how do you write 5,806 in scientific notation?

Answers

Answer:

  5.806 × 10³

Step-by-step explanation:

Put a decimal point to the right of the left-most digit: 5.806. Now multiply by the place value of that digit.

  5.806 × 10³

___

The 5 is in the "thousands" place. Of course a "thousand" is 1000 = 10·10·10 = 10³. The place value multiplier (1000 or 10³) is written using the exponent when we write scientific notation.

False

Answer:

True

Step-by-step explanation:

The negative power property of exponents says that:

[tex]x^{-n}=\frac{1}{x^n}[/tex]

And vice versa:

[tex]\frac{1}{x^{-n}}=x^n[/tex]

Therefore, since our exponent is negative, we can change it to positive if we put it in the numerator. In other words:

[tex]\frac{1}{3^{-4}}=3^4[/tex]

The statement is true.

Latrell runs 5 miles during each track practice. How many track practices would it take for Latrell to run 25 miles?

Answers

Step-by-step explanation:

Answer:

It would take her 5 track practices to run 25 miles because she runs 5 miles each practice. We can divide 25 by 5 which gives us 5. So it would take  5 track practices for Latrell to run 25 miles. Hope this helps.

Atoms are made up of electrons, protons and neutrons. Protons have a positive charge, electrons have a negative charge, and neutrons have no charge. The oxygen atom has 8 electrons and 8 neutrons. How many protons must it have to have 0 charge?​

Answers

Answer:

Protons and neutrons each count for one AMU, and the electron counts for zero AMU. So, if the atomic mass of oxygen is 16, that means we have a total of 16 protons and neutrons. 16 total protons and neutrons minus 8 protons leaves us with 8 neutrons.

 death valley located in the United States is 282 feet below sea level is the level of Galilee located in Israel is 682 feet below sea level how much further between the lowest point in death Valley is the lowest point in the Sea of Galilee

Answers

Answer:

400 feet.

Explanation:

We need to find the difference between the lowest point of Galilee and the lowest point of Death Valley. We can find this by subtracting the lowest point of Galilee by the lowest point of Death Valley. It says the lowest point of Galilee is 682 feet below sea level and the lowest point of Death Valley is 282 feet below sea level. Therefore, we subtract 682 - 282, which equals 400.

find the zeros of the function: g(x)=(x -2)(3x +3)

Answers

Answer:

x = 2 and x = -1

Step-by-step explanation:

The zeroes of the function are found by setting g(x) equal to 0:

g(x) = (x - 2)(3x + 3) = 0

By the Zero Product Property, in order for this equation to be equal to 0, each of (x - 2) or (3x + 3) or both has to equal 0. So, set each equal:

x - 2 = 0

x = 2

3x + 3 = 0

3x = -3

x = -3/3 = -1

The zeroes are thus x = 2 and x = -1.

Find the slope of the line on the graph

Answers

Answer:

m = 1/2

Step-by-step explanation:

Use two points on the line given.

(0 , 2) & (-4 , 0)

You are solving for the slope. The slope formula:

m (slope) = (y₂ - y₁)/(x₂ - x₁)

Let:

(x₁ , y₁) = (-4 , 0)

(x₂ , y₂) = (0 , 2)

Plug in the corresponding numbers to the corresponding variables:

m = (2 - 0)/(0 - (-4))

Simplify:

m = (2)/( 0 - (-4))

m = (2)/(0 + 4)

m = 2/4

Simplify the slope. Divide the common factor 2 from both the numerator and denominator:

m = (2/4)/(2/2) = 1/2

1/2 is your slope.
