## MTALHAHASSAN2 one year ago Need help!! The dephth of water h meters at a seaside resort is given by the formula h= 2.1 sin 2pie(t-3.7)/12.4+5.2. Where t is the time of the day? Use calculater to calculate the time when the water is 7.30 m high.

1. anonymous

can u use the Equation tool? to write it out

2. campbell_st

does this formula give the water level in the resort pool..? so is the equation $h(t) = 2.1\sin(2\pi \frac{(t - 3.7)}{12.4}) + 5.2$

3. campbell_st

is t expressed in hours and minutes or in hours so 7:30 is 7.5?
