Oy = (x + 2)2 + 4
O y = (x - 2)2 - 4
Oy = -(x - 2)2 - 4
Oy=-(x + 2)2 - 4

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
