Please help ASAP, ill give you 10 points and brainliest :c

Molodets [167]

Answer:

answ is last one.

explanation: n>0 means that n is positive number so it will be on right side of zero.

also if u are wondering what is the difference between first one and last one:

empty point like we have in last one means that it doesn't contains that point.

colored point means that it contains that point too.

we have n>0, it doesn't contains zero.

first one would be answer if we would have :

n≥0

Find the distance between the points A(13,2) and B(7,10)

Anna007 [38]

Answer:

$10 = D$

Step-by-step explanation:

Method #1

We can draw a right triangle on the graph upon where the points are located and use the Pythagorean Theorem:

${a}^{2} + {b}^{2} = {c}^{2}$

${6}^{2} + {8}^{2} = {c}^{2}$

$36 + 64 = {c}^{2}$

$100 = {c}^{2}$

$10 = c$

* Whenever we talk about distance, we ONLY want the NON-NEGATIVE root.

_______________________________________________

Method #2

Or, we can use the Distance Formula:

$\sqrt{[-x_1 + x_2]^{2} + [-y_1 + y_2]^{2}} = D$

B[7, 10] A[13, 2]

$\sqrt{[-2 + 10]^{2} + [-13 + 7]^{2}} = D$

$\sqrt{8^{2} + [-6]^{2}} = D$

$\sqrt{64 + 36} = D$

$\sqrt{100} = D$

$10 = D$

* Whenever we talk about distance, we ONLY want the NON-NEGATIVE root.

** You see? It does not matter which method you choose, as long as you are doing the work correctly.

I am delighted to assist you anytime.
