A rocket is shot from an underground bunker. The height of the rocket after t seconds is given by y= -16t^2 + 176t -384 ( measured in feet relative to the surface). Determine how long after the rocket is launched that it will emerge from the ground, and determine how much longer it will be for the rocket to hit the ground?

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

step-by-step explanation:

the answer is b
