From how far on a clear day, and assuming there are no obstructions, could you see from the top of the eiffel tower? take the height of the eiffel tower as 300 m and the radius of the earth as 6240 km.

Answer-

From 61.21 km on a clear day you could see from the top of the Eiffel Tower.

Solution-

From the attachment,

OA = Distance between the top of the Eiffel Tower and center of the earth = 6240 km + 300 m = 6240 km + 0.300 km = 6240.3 km

OB = Radius of the earth = 6240 km

Applying trigonometric properties,

So,

So, the arc length will be,

Therefore, from 61.21 km on a clear day you could see from the top of the Eiffel Tower.

step-by-step explanation:

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
