Someone please help! find x round to the nearest tenth! trigonometry!

TEA [102]

Answer:

Step-by-step explanation:

Look at the picture.

Use sine:

$sine=\dfrac{opposite}{hypotenuse}$

We have a measure of the angle and length of the opposite:

$\alpha=28^o,\ opposite=350\ ft$

$\sin28^o\approx0.4695$

Substitute:

$\dfrac{350}{x}=0.4695$

$\dfrac{350}{x}=\dfrac{4695}{10000}$ <em>cross multiply</em>

$4695x=3500000$ <em>divide both sides by 4695</em>

$x=\dfrac{3500000}{4695}\to x\approx745.5$

The function rule T(m)=450-8m represents the amount of water T(m) (in liters) in a holding tank after being drained at a rate of

suter [353]

Well they give you the equation and they want you to solve for time given that you know the amount of water in the tank. They tell you T=274 and that

T=450-8m so using the value T=274 in the equation to the left gives you:

274=450-8m subtract 450 from both sides

-176=-8m divide both sides by -8

22=m

So 22 minutes have passed when there is 274L remaining...
