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.
Answer:
You don't need help you got this
Step-by-step explanation:
no you don't got this now do your work and stop reading this bye :)
To find the mean....add all the values and divide by the amount of values.....since the mean is given do the opposite...multiply the mean by the amount of values and then minus each value to find x....
113113.101101 * 5 then minus 122122+107107+112112+107107 from it

Perimeter of any figure is all its sides summed up
for a rectangle, with two equal pairs, that means, length + length + width + width or 2length + 2width, or 2(length + width)
but we know the length is 7/5 the width
width = w
perimeter = P
and the length is 7/5 of that
