the depth water, d, in meters, varies with the tides throughout the day and can be modeled by the equation D(t)=2.5 cos(0.675(t-35))+4.3, where t is the number of hours past 12am.
a. Jaya claims that the depth is overall increasing from 8am to 11am by 0.15m per hour. Is Jaya's claim correct? What type of calculation are needed?
b. Abithan claims that at 10am, the depth is decreasing by 0.5m per hour. Is Abitham's claim correct? Provide calculations as needed
