Question 155881: The distance in miles can be seen on the surface of the ocean is given by d=1.4√h where h is the height above the surface of the water. How many feet high above the water (to the nearest tenth) would a pirate have to climb to see 16 miles?

d=1.4%2Asqrt%28h%29 Start with the given equation


16=1.4%2Asqrt%28h%29 Plug in d=16


11.42857=sqrt%28h%29 Divide both sides by 1.4. Note: 16%2F1.4=11.42857 (this is approximate)


130.61221=h Square both sides. Note: %2811.42857%29%5E2=%2811.42857%29%2811.42857%29=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
