Answer:
-4
-10x+6
Step-by-step explanation:
I am going to assume the (Something)x2 means (Something). Then, the expression is 2-6
+4x-6x+9-3=-4-10x+6
Answer:
V = 210 cm³
Step-by-step explanation:
The volume (V) of a cube is calculated as
V = Ah ( A is the area of the base and h is the height )
Here A = 5 × 6 = 30 cm² and h = 7 cm , then
V = 30 × 7 = 210 cm³

Answer:
dh/dt ≈ 0.55 ft/min
Step-by-step explanation:
The volume is given by the formula ...
V = (1/3)πr²h
We have r = h/2, so the volume as a function of height is ...
V = (1/3)π(h/2)²h = (π/12)h³
Then the rates of change are related by ...
dV/dt = (π/4)h²·dh/dt
dh/dt = (4·dV/dt)/(πh²) = 4(35 ft³/min)/(π(9 ft)²)
dh/dt ≈ 0.55 ft/min
