Answer:

14.9 cm

Step-by-step explanation:

To find c using the Law of Sines, you must know angle C. That is found from ...

C = 180° -A -B = 180° -150° -12° = 18°

Then the law of sines tells you ...

c/sin(C) = b/sin(B)

c = b·sin(C)/sin(B) = (10 cm)·sin(18°)/sin(12°)

c ≈ 14.9 cm

pashok25 [27]

Answer:

So you know that the height that is visible above x=0 is 74.98 m
From x=0 below it has a total height of 518.16m to the sea floor

That tells us that we have two parts account for

74.98+518.16m = 593.14 m

Given that (6 3) is on the graph of f(x) find the corresponding point for the function f(-1/2x)

Vlada [557]

$\bf \begin{array}{rllll}
(6&,&3)&f(x)\\
x&&y\\\\
(-\frac{1}{2}x&,&3)&f(-\frac{1}{2}x)\\\\
(-\frac{1}{2}\cdot 6&,&3)\\\\
(-3&,&3)
\end{array}$

keep in mind that, a negative coefficient to "x", will make the graph reflect over the y-axis.
