Question

Graph the function D=V1.5h which gives the approximate distance d in miles to the horizon, where h is the height of the viewer’s eyes above the ground in feet. Approximately how high above the ground must a person be if the horizon is 17.2 miles away?The v is actually square root

Answer 1

\[ D= \sqrt{1.5h} \]

to graph this, pick a number for h, for example h=0
put that number into the formula
\[ D= \sqrt{1.5\cdot 0} = \sqrt{0}= 0\]
(use a calculator, as most numbers are not as easy to do as 0)
you now have a pair of numbers: h=0, D=0
let the h be the x-axis, and D be the y-axis.
plot the point (0,0)

now do h=1
\[ D= \sqrt{1.5\cdot1}= \sqrt{1.5}= 1.22\]
plot the point (1,1.22)
do that for more points and connect the dots.
