Element X decays radioactively with a half life of 10 minutes. If there are 760 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 39 grams? y=a(.5)^{\frac{t}{h}}
y=a(.5)
h

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
