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. How long does it take the tool to hit the surface of the moon? Round your answer to the nearest tenth.

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.

darn right!

step-by-step explanation:

u divide 24 by 3 and u get 8 so if u do 8 time 7 or 8+8+8+8+8+8+8 u get 56 and 56 divided by 7 is 8.
