Please please please please help me. i will do anything, anything!! please

Answer 1

Answer:

$d \approx 2.2$

Step-by-step explanation:

It is the same process as in previous problems.

Once the origin is the point (0, 0):

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

$d=\sqrt{(2-0)^2 + (-1-0)^2}$

$d=\sqrt{2^2 + (-1)^2}$

$d=\sqrt{5}$

$d \approx 2.2$

Answer 2

Answer:

2.2

Step-by-step explanation:

The distance formula

$\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$ with

$x_1=0\\y_1=0\\x_2=2\\y_2=-1$

$\sqrt{(0-2)^2+(0-(-1))^2}=\sqrt{2^2+1^2}=\sqrt{5}$

$\sqrt{5} =2.2360...=2.2$
