A piece of pizza with a diameter of 20 inches is eaten and mZIPZ = 45° . What is

the arc length of the pizza crust inches?

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

what graph

step-by-step explanation:

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

it has to have an angle of 90 degrees
