Do alto de um farol cuja altura é de 20 m avista se um navio sob ângulo de depressão de 30°. A que distância , aproximadamente,
Mkey [24]
Esta é a trigonometria . Se você desenhar uma linha a partir do topo da casa de luz para o barco, você terá a hypotonuse de um triângulo. Um truque é lembrar que este é um triângulo especial. É um triângulo 30-60-90 , que tem propriedades especiais mostradas na fixação abaixo . por isso sabemos que o lado adjacente que não é o hyposonuse é x√3 . Agora sabemos que x<span>√3 = 20
Solve for x.
x</span><span>√3=20
divide both sides by </span><span>√3.
x=20/(</span><span><span>√3)
</span>Try not to have square roots (</span><span><span>√)</span> in denomenator so multiply top and bottom by </span><span>√3 and get
x=(20</span><span>√3)/3
x is what we are looking for so the answer is </span>
20<span>√3 m </span><span>ou cerca de 34.64 m</span>

On a single roll of two number cubes, what is the probability of rolling doubles given that the sum is 6
dexar [7]

Answer:

1/6

Step-by-step explanation:

We can make a Punnett square to find number of favourable outcome

so

            cube1

         +

cube2    1          2          3        4          5         6

1            2         3           4        5          6        7      

2            3         4           5        6          7         8

5         6           7          8         9        10         11

6           7           8          9         10        11         12

The probability of rolling doubles given that the sum is 6

<h3> favourable outcome / number of outcome</h3>

 6 / 36

  1 / 6

Plans call for the reptile Reserve to be surrounded on all sides by a fence. What is the total length of the fence?
Oduvanchick [21]

Answer:

There are no enough information to determine the length of the fence, assuming we were given the perimeter of the fence, and say, the dimension of the fence, then we can easily find the length.

Perimeter of the fence, P = 2(L + B).. If the fence is a rectangular.

L = (P/2) - B

If the fence is square, P = 4L

L = P/4
