A motorist uses a hydraulic jack to change a flat tyre by applying a force of 45 N to the input piston with a radius \( \left(r_{1}\right) \). In operation, the output plunger with a radius \( \left(r_{2}\right) \) applies a force to the car. The ratio \( \left(r_{2} / r_{1}\right) \) has the value 8.3. Ignore the height difference between the input piston and output plunger and determine the force that the output plunger applies to the car.

Answer the following questions for the price-demand equation. \( p+0.001 x=40 \) (A) Express the demand \( x \) as a function of the price \( p \). \( x=40000-1000 p \) The domain of this function is (Type an inequality or a compound inequality.)
