The engine in a jet has a power curve approximated by
y=x230000+32x3811\displaystyle {y}=-\frac{{x}^{{2}}}{{30000}}+\frac{{{32}{x}}}{{38}}-{11}
where x\displaystyle {x} is the RPM and y\displaystyle {y} is the horsepower generated.

At what RPM is the engine putting out maximum horsepower?. Round your answer to three decimal places.
