Question
find the distance between the points (9, 3) and (3, 9). round decimals to the nearest tenth. units
Step1: Identificar las coordenadas
Sean $(x_1,y_1)=(9,3)$ y $(x_2,y_2)=(3,9)$.
Step2: Aplicar la fórmula de distancia
La fórmula de distancia entre dos puntos $(x_1,y_1)$ y $(x_2,y_2)$ es $d = \sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2}$. Sustituyendo los valores, tenemos $d=\sqrt{(3 - 9)^2+(9 - 3)^2}$.
Step3: Calcular los valores internos
$(3 - 9)^2=(-6)^2 = 36$ y $(9 - 3)^2=6^2 = 36$. Entonces $d=\sqrt{36 + 36}=\sqrt{72}$.
Step4: Simplificar y redondear
$\sqrt{72}\approx8.5$.
