The distance they can see: d = √ ( 3 h / 2 )
d ( Addison ) = √ ( 3 · 256/3 / 2 ) = √ 124 = √ 64 · 2 = 8 √ 2d ( Kaylib ) = √ ( 3 · 48 / 2 ) = √ 72 = √ 36 · 2 = 6 √ 2d ( Addison ) - d ( Kaylib ) = 8 √ 2 - 6 √ 2 = 2 √ 2 b. 2 √ 2 mi.

y = -0.75x + 9.5

Step-by-step explanation:

Equation of a circle is given as :

$(x-a)^{2} + (y-b)^2 = r^{2} \\(x-6)^{2} + (y-5)^2 = 4^{2}\\x^{2} - 12x + 36 + y^{2} -10y + 25 = 16\\x^{2} - 12x + y^{2} -10y + 45 = 0\\$

Take the derivative of the above with respect to x

$2x - 12 + 2y dy/dx - 10 dy/dy = 0\\\frac{dx}{dy} = \frac{6 - x}{y-5} \\At (2,8) dy/dx = (6-2)/(8-5) = 4/3\\dy/dx = 4/3\\The slope of the tangent to the circle, m = \frac{-1}{dy/dx} \\m = \frac{-1}{4/3}\\m= -0.75$

The equation of the tangent is given by :

$y - y_{1} = m(x - x_{1})\\ y - 8 = -0.75(x - 2)\\y - 8 = -0.75x + 1.5\\y = -0.75x + 9.5$
