Question
find the distance between the points (1, 2) and (0, 10). write your answer as a whole number or a fully simplified radical expression. do not round. units
Step1: Identificar fórmula de distancia
La fórmula de distancia entre dos puntos $(x_1,y_1)$ y $(x_2,y_2)$ es $d = \sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2}$.
Step2: Asignar valores
Sea $(x_1,y_1)=(1,2)$ y $(x_2,y_2)=(0,10)$. Entonces $x_2 - x_1=0 - 1=-1$ y $y_2 - y_1=10 - 2 = 8$.
Step3: Calcular valores al cuadrado
$(x_2 - x_1)^2=(-1)^2 = 1$ y $(y_2 - y_1)^2=8^2=64$.
Step4: Sumar valores al cuadrado
$(x_2 - x_1)^2+(y_2 - y_1)^2=1 + 64=65$.
Step5: Calcular raíz cuadrada
$d=\sqrt{65}$.
