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!
Answer:
The volume of the sphere with radius 8 cm is 2143.573 centimeters³
Step-by-step explanation:
Given as :
The radius of the sphere = r = 8 cm
Let The volume of sphere = v cm³
<u>Now, According to question</u>
Volume of sphere =
× π × radius³
where r is radius of sphere
π = 3.14
Or, v =
× 3.14 × r³
Or, v =
× 3.14 × 8³
Or, v =
× 1607.68
Or, v = 
∴ v = 2143.573 cm³
So, The volume of the sphere = v = 2143.573 cm³
Hence, The volume of the sphere with radius 8 cm is 2143.573 centimeters³ Answer
