Viktor [21]

<u>Given:</u>

The angle of elevation from the point on the ground to the top of the tree is 34° and the point is 25 feet from the base of the tree.

We need to determine the height of the tree.

<u>Height of the tree:</u>

Let the height of the tree be h.

The height of the tree can be determined using the trigonometric ratio.

Thus, we have;

tan \ \theta=\frac{opp}{adj}

Substituting the values, we get;

tan \ 34^{\circ}=\frac{h}{25}

Multiplying both sides by 25, we have;

tan \ 34^{\circ} \times 25=h

 0.6745 \times 25=h

       16.8625=h

Rounding off to the nearest tenth of a foot, we get;

16.9=h

Thus, the height of the tree is 16.9 feet.

Hence, Option B is the correct answer.

Find the 10th term of the geometric sequence 1, 3, 9, ...
ladessa [460]

Answer:

a(10) = 3^9 = 19683

Step-by-step explanation:

In this sequence each new term is equal to 3 times the previous term.  Thus, 3 is the common ratio.  The first term is 1.

The general formula for the nth term of a geometric sequence i

a(n) = a(1)*r^(n -1), where r is the common ratio.

Here, a(n) = 1*3^(n - 1), and so

the 10th term is

           a(10) = 1*3^(10 - 1), or

            a(10) = 3^9 = 19683
