The position of an object moving in a straight line is given by the following formula where s is in meters and t is the time in seconds the object has been in motion. f[ s = 2t^2 - 3tf] how long (to the nearest tenth) will it take the object to move 9 meters?

3 s

Explanation:

s = 2t^2 - 3t

s = 9 m

(t - 3)(2t + 3) = 0

time cannot be negative, so t = 3 s

Thus, the object takes 3 second to move 9 m.

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
