Answer:
2.2 seconds.
Step-by-step explanation:
We have been given that an astronaut on the moon drops a tool from the door of the landing ship. The quadratic function
models the height of the tool, in meters, after x seconds.
To find the time, it will take for the tool to hit the surface of moon, we will set
and solve for x as:



Divide both sides by negative 2:


Now, we will take square root of both sides:



Since time cannot be negative therefore, it will take 2.2 seconds for the tool to hit the surface of the moon.
