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

Which is a y-intercept of the continuous function in the table? (0, –6) (–2, 0) (–6, 0) (0, –2)
photoshop1234 [79]

Y- intercept is a point where any graph crosses the y- axis.

X- intercept is a point where any graph crosses the x- axis.

This means the coordinate of the point of intersection will always have the x point as 0. So any point of the form ( 0, y) is the y- intercept. Any point of the form (x,0) is the x- intercept.

Given point are :

(0,-6) : y intercept

(-2,0) : x intercept

(-6,0): x- intercept

(0,-2): y- intercept

a delivery truck is carrying and 8713 lb load of pet food. At a weighing station, the loaded truck weighs 17200 lb. What is the
netineya [11]

We know that the load is 8713 lbs.

The total weight (truck + load) is 17200 lb.

Then, we can calculate the weight of the empty truck as:

\begin{gathered} L=8713 \\ W=L+T=17200 \\ \Rightarrow T=W-L \\ T=17200-L=17200-8713=8487 \\  \end{gathered}

Answer: the empty truck's weight is 8487 lb.

T: empty truck's weight

W: total weight (loaded truck's weight)

L: Load

The equation is:

T = W - L
