If we draw the triangle, the opposite side to 3° angle would be "10" less than total height of 250 because Nick is 10 feet above water level, so that side will be:

250 - 10 = 240

The hypotenuse of the triangle is the length of line of sight. We can call this "x".

So, using trigonometric ratio of sine (opposite/hypotenuse), we can write:

$Sin(3)=\frac{240}{x}$

Now, we cross multiply and solve for x, line of sight length:

$Sin(3)=\frac{240}{x}\\x=\frac{240}{Sin(3)}\\x=4585.8$

Which statement correctly describes the relationship between the graph of f(x)g(x) and g(x)=f(x−7)?

Lelu [443]

G(x) would have to be -->7 units.
The relationship between f(x) and s(x) where s(x)=af(x-b)+z is that g(x) is f(x) stretched by the reciprocal of a, b is the liar (all x values go up if b goes down and visa versa), and it moves up z units.
