The distance, in miles, from an observer to the horizon varies directly to the square root of the height of the observer, measured in feet. For a height of 16 feet, the distance to the horizon is 4.88 miles. a. Find the constant of proportionality:

b. Equation:

c. Find the distance to the horizon for a person at a height of 25 feet:

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
