(-4,5) and (4,0) find the distance between each pair of points

aleksklad [387]

Answer:

9.4339 units

Step-by-step explanation:

Here we are given with two coordinates and asked to determine the distance between them.

Here we are going to use the distance formula, which is given as under

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

Where

$(x_1,y_1) = (-4,5)$

$(x_2,y_2) = (4,0)$

Replacing these values in the distance formula

$D =\sqrt{(-4-4))^2+(5-0)^2}$

$D =\sqrt{(-8)^2+(5)^2}$

$D =\sqrt{64+25}$

$D =\sqrt{89}$

$D= 9.4339$

Hence the distance is 9.4339 units
