Question

Distance between A(2,3) and B (-3,-9) is _____​

Answer 1

Answer:

d(P1,P2) = (x2 x1)2 + (y2 y1)2 + (z2 z1)2. This can be proved by repeated application of the Pythagorean Theorem. Example The distance between P1 = (2,3,1) and P2 = (8,5,0) is d(P1,P2) = (8 2)2 + (5 3)2 + (0 1)2 = 36 + 64 + 1 = 101 10.05.

Answer 2

Answer:

13 units

Step-by-step explanation:

using distance formula,

D = √(2+3)^2 + (3+9)^2

= √25 + 144

=√169

= 13 units
