The endpoint coordinates of AB are A(2, -10) & B(12, 5). Find the coordinates of the point that is 2/5 from A to B.

<h3>Answer: $\large \boldsymbol {\sf 2\sqrt{13} \approx7,2}$ </h3>

Step-by-step explanation:

Find the distance between points A and B by the formula:

$\large \boldsymbol {\sf D=\sqrt{(x_1-x_2)^2+(y_1+y_2)^2} }$

$\large \boldsymbol{} \sf D=\sqrt{(2-12)^2+(-10-5)^2} =\sqrt{100+225} =\boldsymbol {\sqrt{325}=5\sqrt{13} }$

By the condition we are told to find 2/5 the distance between points A and B

$\sf \large \boldsymbol {} \dfrac{2}{5} \cdot D=5\sqrt{13} \cdot \dfrac{2}{5} =\boxed{\sf 2\sqrt{13}}$

We can also find the distance between them through the Pythagorean theorem we will complete a right triangle

AB²=AC²+BC²

AB=√AC²+BC²

Where AC=10 ; BC=15

AB= $\boldsymbol {\sf \sqrt{15^2+10^2}=\sqrt{325}=5\sqrt{13} }$

Then 2/5* AB=2 $\sqrt{13}$
