find the distance between the two points rounding to the nearest tenth (if necessary).
(2, -3) and (8, -7)
Step1: Identificar los valores
Sean $(x_1,y_1)=(2, - 3)$ y $(x_2,y_2)=(8,-7)$.
Step2: Aplicar la fórmula de distancia
La fórmula de distancia entre dos puntos $(x_1,y_1)$ y $(x_2,y_2)$ es $d=\sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2}$. Sustituimos los valores: $d=\sqrt{(8 - 2)^2+(-7+3)^2}$.
Step3: Calcular los valores internos
Calculamos $(8 - 2)^2=6^2 = 36$ y $(-7 + 3)^2=(-4)^2=16$. Entonces $d=\sqrt{36 + 16}$.
Step4: Sumar y calcular la raíz
Sumamos $36+16 = 52$, y $d=\sqrt{52}$. Simplificando $\sqrt{52}=\sqrt{4\times13}=2\sqrt{13}\approx7.2$.
