An estimate for how far we can see on any given day is given by the formula v = 1.225/a, where vis the visibility in miles, and a is the altitude in feet.
If a 4-ft tall person is standing on a structure, then how tall (to the nearest foot)
would the structure need to be for this person to see 12 miles?

step-by-step explanation:

step-by-step explanation:

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.

you would 18 *0.25 = 4.5
