HELP PLS! A boat is heading towards a lighthouse, whose beacon-light is 102 feet above the water. From point AA, the boat’s crew

measures the angle of elevation to the beacon, 13^{\circ}
, before they draw closer. They measure the angle of elevation a second time from point BB at some later time to be 22^{\circ}

. Find the distance from point AA to point BB. Round your answer to the nearest tenth of a foot if necessary.

Answer:

Distance from point AA to point BB = 189.3 feet

Step-by-step explanation:

Let the distance from point AA to the base of the lighthouse be represented by x, and the distance from point BB to the base of the lighthouse be represented by y. So that;

distance from point AA to point BB = x - y

To determine the value of x, applying the required trigonometric function;

Tan θ = \frac{opposite}{sdjacent}

Tan 13 = \frac{102}{x}

x = \frac{102}{Tan 13}

  = 441.81 feet

x = 441.8 feet

To determine the value of y;

Tan 22 = \frac{102}{y}

y = \frac{102}{Tan 22}

  = 252.46

y = 252.5 feet

Thus,

distance from point AA to point BB = 441.8 - 252.5

                                                           = 189.3 feet

Helppp!!!!laura is playing a card game with her friend.she will draw two cards from those pictured.
puteri [66]

Answer:

10

30%

Step-by-step explanation:

In this case it would be the combination of 2 taken from 5.

That is, when n = 5 and r = 2

nCr = n! / r! * (n-r)!

replacing

5C2 = 5! / (2! * 3!)

5C2 = 10

Which means that the sample space is 10 possible combinations.

the probability that the card you draw is even is 3/5, since there are 3 even cards that exist and 5 is the total number of cards.

Now, so that both are for it would be the multiplication of the previous probability and 2/4 because an even card and a card in general have already been drawn:

(3/5) * (2/4) = 0.3

So the probability that both are even is 30%

What is coefficient of the term of degree of degree 5 in the polynomial below
Luden [163]

Answer:

C

Step-by-step explanation:

given 3x^{6} + 5 - x² + 4x^{5} - 9x

The degree of a term is determined by the value of its exponent.

A term of degree 5 has an exponent of 5

In the polynomial given this term is 4x^{5}

With a coefficient of 4 → C
