Question 155881
{{{d=1.4*sqrt(h)}}} Start with the given equation



{{{16=1.4*sqrt(h)}}} Plug in {{{d=16}}}



{{{11.42857=sqrt(h)}}} Divide both sides by 1.4. Note: {{{16/1.4=11.42857}}} (this is approximate)



{{{130.61221=h}}} Square both sides. Note: {{{(11.42857)^2=(11.42857)(11.42857)=130.61221}}} (this is approximate)



-------------------------------

Answer:


So the solution is {{{h=130.61221}}} which rounded to the nearest tenth gives us {{{h=130.6}}}




So the pirate would have to climb about 130.6 feet to see 16 miles
