Question 172472This question is from textbook Introductory Algebra
: The distance in miles that can be seen on the surface of the ocean is given by d = 1.4 sqrt 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? This question is from textbook Introductory Algebra

Solution:
d = 1.4 sqrt (h)
now, we are required to find out the height at which the disatnce of 16 miles will be visible. To find the value of h we need to substitute the value of d as 16 in the above equation, hence
sqrt(h)= 16/1.4
squaring both the sides
h = (16*16)/(1.4*1.4)
= 130.6
