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 he

PSYCHO15rus [73]

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,

$\Rightarrow\cos \theta=\dfrac{OB}{OA}\\\\\Rightarrow \theta=\cos^{-1}\dfrac{OB}{OA}\\\\\Rightarrow \theta=\cos^{-1}\dfrac{6240}{6240.3}\\\\\Rightarrow \theta=0.562$

So,

$\text{Circumference of the earth} = 2\pi \times radius = 2\pi \times 6240=12480\pi=39207 km$

So, the arc length will be,

$=\dfrac{0.562}{360}\times 39207\\\\=61.21\ km$

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

Which construction of parallel lines is justified by the theorem "when two lines are intersected by a transversal and the corres

Ugo [173]

Answer:

c

Step-by-step explanation:

I think you missed attaching the photo, please see my attachment.

And the correct answer is C,

When you look at where the arc meets the parallel lines, if you create a seam between two points, you get a straight line parallel to the horizontal lines so it makes the corresponding angles are congruent.

Integration Rule [Reverse Power Rule]: $\displaystyle \int {x^n} \, dx = \frac{x^{n + 1}}{n + 1} + C$

Integration Property [Multiplied Constant]: $\displaystyle \int {cf(x)} \, dx = c \int {f(x)} \, dx$

Step-by-step explanation:

Step 1: Define

Identify

Point (0, 18)

$\displaystyle \frac{dy}{dt} = \frac{1}{8} t$

Step 2: Find General Solution

Use integration

[Derivative] Rewrite: $\displaystyle dy = \frac{1}{8} t\ dt$
[Equality Property] Integrate both sides: $\displaystyle \int dy = \int {\frac{1}{8} t} \, dt$
[Left Integral] Integrate [Integration Rule - Reverse Power Rule]: $\displaystyle y = \int {\frac{1}{8} t} \, dt$
[Right Integral] Rewrite [Integration Property - Multiplied Constant]: $\displaystyle y = \frac{1}{8}\int {t} \, dt$
[Right Integral] Integrate [Integration Rule - Reverse Power Rule]: $\displaystyle y = \frac{1}{8}(\frac{t^2}{2}) + C$
Multiply: $\displaystyle y = \frac{t^2}{16} + C$
