Distance

What is the distance between the origin and the point (-11; 13)?

Correct answer:

r =  17.03

Step-by-step explanation:

A=(11,13) r = OA r2 = (AO)2  r = (AxOx)2+(AyOy)2 r = (Ax0)2+(Ay0)2 r=Ax2+Ay2=(11)2+132=290=17.03

The origin has coordinates (0,0). Then, use the distance formula to find the distance between the origin and the given point (x,y). The distance formula is the Pythagorean theorem applied to this problem. The resulting distance is the square root of  x2 + y2.
