Final answer:
The magnitude of AB is 5
Step-by-step explanation:
To find the magnitude of AB with the initial point A(1,5) and terminal point B(6,5), we can use the distance formula. The distance formula is given by:
AB = sqrt((x2 - x1)^2 + (y2 - y1)^2)
Plugging in the coordinates (1,5) and (6,5), we get:
AB = sqrt((6 - 1)^2 + (5 - 5)^2)
AB = sqrt(5^2 + 0^2)
AB = sqrt(25 + 0)
AB = sqrt(25)
AB = 5
