7 minutes and 10 secs
Step-by-step explanation:
Answer:
x-intercept: The plumber drained all the water out after 9 hours.
Relative maximum or minimum: The amount of water reached 70 liters before the draining began.
Increasing or decreasing interval: Over the first 5 hours, the leak just got bigger and bigger.
Step-by-step explanation:
W(t) is the amount of water in the basement. When W(t) = 0, there is no water in the basement. When W(t) = 0, W(t) is a x-intercept. So, x-intercept: The plumber drained all the water out after 9 hours.
The water level gets to a relative maximum after about 5 hours, when the water reaches about 70 liters. So, relative maximum or minimum: The amount of water reached 70 liters before the draining began.
The water level keeps increasing until the relative maximum. That is at 5 hours when the water level is 70 liters. After that point, the water level decreases as the water is being drained until the water level is 0 at 9 hours. So, the increasing or decreasing interval: Over the first 5 hours, the leak just got bigger and bigger.
Hope this helps!
