Write the equation and then determine the amplitude, period, and frequency of the simple harmonic motion of a particle moving uniformly around a circle of radius 7 units, with angular speed 4 radians per second. The equation is \( \mathrm{s}(\mathrm{t})=\square \)

Beginning at sea level, a scuba diver dove \( 1 \frac{2}{3} \) meters into the water, and then dove an additional \( 3 \frac{2}{5} \) meters. At what elevation is the scuba diver? The elevation of the scuba diver is

Use the compound interest formula to compute the balance in the following account after the stated period assuming interest is compounded annually. \( \$ 9000 \) invested at an APR of \( 2.4 \% \) for 12 years. The balance in the account after 12 years is \( \$ \) (Round to the nearest cent as needed.)
