Derive an equation d = asin(bt) for the displacement d (in feet) of a buoy in relation to sea level over t seconds. (assume the buoy starts with a displacement of 0 and then goes up to its maximum height.) the maximum displacement of the buoy is 1.5 feet in either direction, and the time it takes for the buoy to go from its highest point to its lowest point is 3 seconds.

a= 1.5

b= pi/3

Select the equation that models the movement of the buoy. the answer is the 2nd option  

Step-by-step explanation:

.25

step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
