What is y=0.1cos2(x+0.2)+0.8 rewritten in terms of x=?

john earns $14.00 for two hours of work.

493 would be the correct answer

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
