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:
7 is the (constant) coefficient of 1/y, but no, it is not the coefficient of y
Step-by-step explanation:
7/y can be rewritten as 7(1/y) or as 7(y^[-1]). In this case, yes, 7 is the (constant) coefficient of 1/y, but no, it is not the coefficient of y.
It would be called
Pythagoras theorum.
4x + 6 = -26
I'm not sure if your supposed to solve, but I will anyways :)
4x + 6 = -26
-6 -6
4x = -32
x = -8
Hope this helps!
