Question

Distance formula
(3,0) (3,-3)

Answer 1

The formula for distance between two points is:

$\sqrt{(x_{2} -x_{1})^{2} + (y_{2} -y_{1})^{2}}$

In this case:

$x_{2} =3\\x_{1} =3\\y_{2} =-3\\y_{1} =0$

^^^Plug these numbers into the formula for distance like so...

$\sqrt{(3-3)^{2} + (-3-0)^{2}}$

To solve this you must use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)

First we have parentheses. Remember that when solving you must go from left to right

$\sqrt{(3-3)^{2} + (-3-0)^{2}}$

3 - 3 = 0

$\sqrt{(0)^{2} + (-3-0)^{2}}$

-3 - 0 = -3

$\sqrt{(0)^{2} + (-3)^{2}}$

Next solve the exponent. Again, you must do this from left to right

$\sqrt{(0)^{2} + (-3)^{2}}$

0² = 0

$\sqrt{0 + (-3)^{2}}$

(-3)² = 9

$\sqrt{(0 + 9)}$

Now for the addition

$\sqrt{(0+9)}$

0 + 9 = 9

√9 <<<This can be further simplified to:

3 units

***Remember that the above answers are in terms of units

Hope this helped!
