Answer:
Increasing by $66 per day
Step-by-step explanation:
If sales are dropping at a rate of 2 per day, the sales function is:
If price is increasing by $1 per day, the daily price function is:
Revenue is given by daily sales multiplied by daily price:
The derivate of the revenue function gives us the daily rate of change in revenue:
Currently (t=0) her daily revenue is changing by:
Her revenue is increasing by $66 per day.
The function f(t) = 7 cos(pi over 4t) + 12 represents the tide in Light Sea. It has a maximum of 19 feet when time (t) is 0 and a minimum of 5 feet. The sea repeats this cycle every 8 hours
To find the height of the tide after 2 hours, we plug in 2 for t and find out f(2)
We know that cos (pi/2) is 0
So f(2)= 12
After two hours, the height of the tide is 12 feet
