Answer:
dh/dt = 0,07 ft/min
Step-by-step explanation:
The swimming pool has the shape of right circular cylinder, therefore its volume is
V(c) = π*x²*h
Where x is the radius of the base and h the height
We take differentiation on both sides of the equation to get:
dV/dt = π*x²*dh/dt
The rate of change in height of water in the pool, is independent of the height of the water, since the pool is a right crcular cylinder, and dV/dt is constant at 8 ft³/min.
Then:
8 = π*x²*dh/dt
dh/dt = 8 / π*x²
dh/dt = 8/113,04
dh/dt = 0,07 ft/min
Answer:
solution 1: 3
solution 2: 9
Step-by-step explanation:
1) solution 1 + solution 2 = 12;
2) solution 1 * solution 2 = 27;
3) only 3 and 9 meet these two requirements.
note. this equation can be resolved using another way.
I would help but I’m not good with graphs
I would answer the question but there are no answer choices, so if you could add that maybe I could help! :)
-4 < 6
Negative number always less than positive number
