11a + 2
The answer is 9/7!! Hope it helps
Answer:
8 hours
Step-by-step explanation:
Joe's data shows the minimum to be 4 hours after his arrival at the beach. The time between maximum and minimum is half a period. (The other half brings the function back to its maximum.) If half a period is 4 hours, the whole period is 8 hours.
Y+4 = (-4/3)(x-6)
