Answer:
The water in the tank filled to capacity lasts 20 days.
Step-by-step explanation:
Total number of students in the hostel = 300
The average need of water per day = 36,000 L
The dimensions of the tank = 10 m × 8 m × 9 m
Now, the capacity of the tank = LENGTH X WIGHT X HEIGHT
= 10 m × 8 m × 9 m = 720 cubic meters
Now,
⇒
So, the capacity of the tank = 720,000 L
and the average usage of water by 300 students =
⇒
or, number of days = 20
Hence, the water in the tank filled to capacity lasts 20 days.
Answer:
The vertex form of a quadratic function:
(h,k) - the coordinates of the vertex
If a>0, then the parabola opens upwards, so the vertex is the minimum of the function.
If a<0, then the parabola opens downwards, so the vertex is the maximum of the function.
