An astronaut on the moon drops a tool from the door of the landing ship. The quadratic function f(x)=-2x^2+10 models the height
Gekata [30.6K]

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 f(x)=-2x^2+10 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 f(x)=0 and solve for x as:

-2x^2+10=0

-2x^2+10-10=0-10

-2x^2=-10

Divide both sides by negative 2:

\frac{-2x^2}{-2}=\frac{-10}{-2}

x^2=5

Now, we will take square root of both sides:

\sqrt{x^2}=\pm\sqrt{5}

x=\pm 2.236067

x\approx 2.2

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