We take the function as a sequence

Term 1 ⇒ 5
Term 2 ⇒ 4
Term 3 ⇒ 3.2

Between terms, there is a common ratio of ⁴/₅
We get it from here:
Term 2 / Term 1 = $\frac{4}{5}$
Term 3 / Term 2 = $\frac{3.2}{4}$ = $\frac{4}{5}$

When a sequence has a common ratio between term, the sequence is a Geometric Sequence

$n_{th}term=ar^{n-1}$
Where $a$ is the first term, $r$ is the common ratio, and $n$ is the term number

We have: $a=5$ and $r= \frac{4}{5}$
The formula for the function is

$f(x)=5( \frac{4}{5})^{x-1}$

Given :-

x/2 = 3

To Find :-

The value of 2x + 2 .

Solution :-

The given equation to us is ,

$\longrightarrow$ x/2= 3

$\longrightarrow$ x = 3*2

$\longrightarrow$ x = 6

Now we need to find out ,

$\longrightarrow$ 2x + 2

$\longrightarrow$ 2(6) + 2

$\longrightarrow$ 12 + 2

$\longrightarrow$ 14

Hence the required answer is 14.

Answer:

30.1 feet.

Step-by-step explanation:

We have been given that a school flag poll casts a 16 foot shadow on the lawn. A teacher stood at the shadows edge and measure the angle of elevation to the top of the poll at 62°. We are asked to find the height of the tall.

First of all, we will draw a diagram to represent our give scenario as shown in the attachment.

We can see that side length with 16 feet is adjacent side and height of the pole (h) is opposite side to angle of elevation.

We know that tangent relates opposite side of a right triangle to its adjacent side.

$\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}$
