Answer:
a. 5
b. 5
c. 6√2
d. √34
e. 43 (appx.)
Step-by-step explanation:
The distance between two points on the coordinate plane having coordinate (x1, y1) and (x2, y2) is given by .... (1)
a. Hence, the distance between points A(2,3) and point B(6,6) is units. {Using equation (1)}
b. Coordinates of A and B in the Cartesian coordinate plane are (2,3) and (6,6) respectively.
Hence, the distance between A and B is units.
c. Coordinates of A and B in the Cartesian coordinate plane are (-1,5) and (5,11) respectively.
Hence, the distance between A and B is units.
d. Coordinates of A and B in the Cartesian coordinate plane are (1,-2) and (-2,3) respectively.
Hence, the distance between A and B is units.
e. Coordinates of A and B in the Cartesian coordinate plane are (12,-12) and (-23,13) respectively.
Hence, the distance between A and B is units. (Approximate) (Answer)
