What’s the distance between (4,-9) and (5,3)
laila [671]

Answer: Distance = √145

Concept:

Here, we need to know the concept of the distance formula.    

The distance formula is the formula, which is used to find the distance between any two points.

If you are still confused, please refer to the attachment below for a clear version of the formula.

Solve:

<u>Given information</u>

(x₁, y₁) = (4, -9)

(x₂, y₂) = (5, 3)

<u>Given formula</u>

Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

<u>Substitute values into the formula</u>

Distance = \sqrt{(5-4)^2+(3+9)^2}

<u>Simplify values in the parentheses</u>

Distance = \sqrt{(1)^2+(12)^2}

<u>Simplify exponents</u>

Distance = \sqrt{1+144}

<u>Simplify by addition</u>

Distance = \sqrt{145}

Hope this helps!! :)

The population of California is approximately 38,040,000. The population of Texas is about 2.606 × 10^7. What is the approximate
ivann1987 [24]
With scientific notation remember this rule; if the exponent is positive, move the decimal point that many places to the right. If it is negative move it that many places to the left. What that will do is make the number larger or smaller to the correct value.
 
So for example, if you had to solve 1.02 x 10^4 you would move the decimal four places to the right. So you would end up with 10200. 
As another example if you had to solve 1.02 x 10^-2 you would move the decimal two places to the left. That would give you .0120. 

So now we are onto your problem. 2.606 x 10^7.
You would move the decimal seven places to the right, because the exponent is positive, that will make your number larger(which would make more sense if you were adding populations, right?).
That would give you 26,060,000 people living in Texas.
From there simply add the two populations together and you will have your answer!
