3. A utility pole is 38 ft tall. The pole creates a 53 ft shadow. What is the angle of elevation of the sun? Round your answer t

dybincka [34]

Answer:

The angle of elevation of the sun is $36\degree$ .

Step-by-step explanation:

Let $x$ be the angle of elevation of the sun as shown in the diagram.

Then the side length which is $38$ feet is opposite to $x$ and the side length which is $53$ feet is adjacent to $x$ .

Therefore we use the trigonometric ratio that involves the opposite and adjacent sides, which is the tangent ratio.

$\tan x=\frac{38}{53}$

$\Rightarrow \tan x=0.71698$

We solve for $x$ to get,

$x=\arctan (0.71698)$

$\Rightarrow x=35.63981$

To the nearest degree, the angle of elevation is $36\degree$

Given a term in a geometric sequence and the common ratio, find the explicit formula, a11=5120 ans r=-2

sweet-ann [11.9K]

Answer:

$U_n=5(-2)^{n-1}$

Step-by-step explanation:

Given a geometric sequence, the nth term of the geometric sequence is obtained by using the formula:

$U_n=ar^{n-1}$

If the eleventh term, $a_{11}=5120$

and the common ratio, r=-2.

Then:

$5120=a(-2)^{11-1}\\a=\frac{5120}{2^{10}} =5$

The explicit formula for the sequence is:

$U_n=5(-2)^{n-1}$
