The height (h) (in feet) of a certain aircraft (t) seconds after it leaves the ground is modeled by h(t) = -9.1t^2 + 591.5t + 20,388.125. At what time will the aircraft hit the ground?

246

step-by-step explanation:

25/14 or 1.

the dots mean that it has infinitely more numbers behind it

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
