Sagot :
Step-by-step explanation:
1)
d² = (6-1)²+(3-1)²
or, d² = 5²+2²
or, d² = 25+4
so, d² = 29
so, d = 5.4 units
2)
d² = (4+2)²+(3-1)²
or, d² = 6²+2²
or, d² = 36 + 4
so, d² = 40
so, d = 6.3 units
3)
d² = (3-1)²+(-2-1)²
or, d² = 2²+(-3)²
or, d² = 4+9
or, d² = 13
so, d = 3.6 units
Answer:
1) 5.4 2) 6.3 3) 3.6
Step-by-step explanation:
Formula to find distance: [tex]d=\sqrt{(x2-x1)^{2} +(y2-y1)^{2} }[/tex]
1) coordinates = ( 1 , 1 ) , ( 6 , 3 )
distance = √(6-1)²+(3-1)²
= 5.4
2) coordinates = ( -2 , 1 ) , ( 4 , 3 )
distance = √(4--2)²+(3-1)²
= 6.3
3) coordinates = ( 1 , 1 ) , ( 3 , -2 )
distance = √(3-1)²+(-2-1)²
= 3.6
