What is the distance between –3 and 2 on the number line?

1 answer:

7 0

The distance between -3 and 2 is 5 because if you were to draw a number line and put -3 and 2, you have to count what’s on the inside

Answer:

Step-by-step explanation:

$x^{-6}*x^{-5}=x^{(-6)+(-5)}=x^{-11}=\frac{1}{x^{11}}$

$x^{a}*x^{b}=x^{a+b}\\\\x^{-a}=\frac{1}{x^{a}}$

Tommy can lay a brick walkway by himself in 12 hours. Robert does the same job in 10 hours.

Answer:

5 5/11 hours

Step-by-step explanation:

So, there is a trick to doing this.

You would first need to get their work rate into the same measurements.

That's why we will find out how much they each work in one hour.

Tommy does 1/12 of the work in one hour while Robert does 1/10.

Here we can add them both up to make 11/60.

They finish 11/60 of the work in one hour.

They finish the job in 5 5/11 hours.

<h3>Answer: Approximately 6.4 units</h3>

==================================================

Explanation:

The origin is the point (0,0)

Use the distance formula to find the distance from (0, 0) to (4, -5)

Let

$(x_1,y_1) = (0,0)\\\\(x_2,y_2) = (4,-5)\\\\$

be our two points. Plug those values into the distance formula below and use a calculator to compute

$d = \sqrt{\left(x_1-x_2\right)^2+\left(y_1-y_2\right)^2}\\\\d = \sqrt{\left(0-4\right)^2+\left(0-(-5)\right)^2}\\\\d = \sqrt{\left(0-4\right)^2+\left(0+5\right)^2}\\\\d = \sqrt{\left(-4\right)^2+\left(5\right)^2}\\\\d = \sqrt{16+25}\\\\d = \sqrt{41} \ \text{ exact distance}\\\\d \approx 6.40312 \ \text{ approximate distance}\\\\d \approx 6.4\\\\$
