1 State the transformation which maps \( y=\sin x \) onto:
\( \begin{array}{lll}\text { a } y=\sin x-1 & \text { b } y=\sin \left(x-\frac{\pi}{4}\right) & \text { c } y=2 \sin x \\ \text { d } y=\sin 4 x & \text { e } y=\sin \frac{x}{4} & \text { f } y=\sin \left(x-\frac{\pi}{3}\right)+2\end{array} \)
Q:

Q:
\( 16\sin (x)^{4}-\sin (y)^{4} \)
Q:
A boat heading out to sea starts out at Point \( A \), at a horizontal
distance of 1433 feet from a lighthouse/the shore. From that point,
the boat's crew measures the angle of elevation to the lighthouse's
beacon-light from that point to be \( 15^{\circ} \). At some later time, the crew
measures the angle of elevation from point \( B \) to be \( 6^{\circ} \). Find the
distance from point \( A \) to point \( B \). Round your answer to the nearest
tenth of a foot if necessary.
Q:
\( \left. \begin{array} { l l } { x + 30 ^ { \circ } } & { 2 x - 30 ^ { \circ } } \\ { } & { } \\ { 150 ^ { \circ } - x } & { 5 x } \\ \hline \end{array} \right. \)
