Question

Find the distance between the two points in simplest radical form.
(3,9) and (-2,4)

Answer 1

Explaination :

Here we would be using distance formula to calculate the distance between those two points.

★ Points are,

• (3 , 9)
• (-2 , 4)

★ Distance Formula :

• 
  `\huge \large \boxed{\sf{{d \: = \: \sqrt{(x _(2) - x _(1)) {}^(2) \: + \: (y _(2) - y _(1)) {}^(2) }}}} \: \red\bigstar`

★ We have :

x1 = 3

x2 = -2

y1 = 9

y2 = 4

★ Substituting the values :

• Refer the attachment.

Centroid of a triangle :-

• 
  `\boxed{ \sf{Centroid \: = \: (x_1 \: + \: x_2 \: + \: x_3)/(3) }} \: \pink\bigstar`

Midpoint of two points:-

• 
  `\boxed{ \sf{M \: = \: (x_1 \: + \: x_2 )/(2) \: , \: (y_1 \: + \: y_2 )/(2)}} \: \pink\bigstar`
