Question

Calcule a distância entre os pontos.
A- A(3,9) e C(-7,0)
B- D(1/2, -1) e M(4,-6)
C-T(√6,2) e H(2,-4)
D-J(0,0) e L(8,-6)

Answer 1

dAC= √(-7(-3)² + (0-9)            
dAC= √(-10)² + (-9)²
dAC= √100+81
dAC=√181

dDM= √(4-1/2) + (-6(-1)²
dDM= √(8/2-1/2)² + (-6+1)²
dDM=√(7/2)² + (-5)²
dDM= √49/4+25
dDM= √149/4

dTH=√(2-√6)² + (-4(-2)²
dTH=√4-4√6+6+(-6)²
dTH=√10-4√6+36
dTH=√46-4√6

dJL= √(8-0)² + (-6(-0)²
dJL= √(8)² + (-6)²
dJL= √64+36
dJL= √100
dJL= 10
