The amount of torque that a mass is based the distance from the fulcrum. The red blocks will create counter-clockwise motion, and the green will create clockwise motion. We need the red and green to be equal.

6 + 4 + 2(2) = 2(3) + 5 + x

14 = 11 + x

x = 3

So the green block should be placed at 3 on top the other two blocks.

solmaris [256]

Answer:

Its the last option

y = 1488.33x + 23800 ; $172,600.

Step-by-step explanation:

The slope of the trend line = (median value for 2000 - median value for 1940) / 60

= 89300 / 60

= 1488.33.

So the equation is 1488.33x + 23,800

Estimate for 2040
