To the nearest thousand is 23,000 and the nearest ten thousand is 20,000
Answer:
A) 48 in : initial height of the water
B) 40.5 in : height of the water after 5 days
C) 32 days
D) Yes, should be restricted.
Domain: 0 ≤ d ≤ 32
Step-by-step explanation:

A)

48 in is the initial height of the water
B)

40.5 in is the height of the water after 5 days
C) when the pool is empty, h = 0.
So set the equation to zero and solve for d.

D) Yes, the domain should be restricted because when d > 32, h < 0 and the height of the water in the pool cannot be negative
Domain: 0 ≤ d ≤ 32
Answer:
You need to carry the one over by subtracting 1 from 33. The new equation will be 18n = 32
3.36/10.5 = 0.32
It costs $0.32 an ounce
I think it is B
hope this helps
