Answer:
A
Step-by-step explanation:
[f(x) + g(x)]=x²+3x-6+1
=x2+3x-5
If the volume of a cone is V=π(r*r) * h/3
radius=2
V=<span>π(2*2) * (9)/3
3.14(4) * (3)
Volume=37.68 inches cubed</span>

Answer:
5/9 m/min
Step-by-step explanation:
The depth of the water is 2/5 of the depth of the trough, so the width of the surface will be 2/5 of the width of the trough:
2/5 × 2 m = 4/5 m
Then the surface area of the water is ...
A = LW = (18 m)(4/5 m) = 14.4 m²
The rate of change of height multiplied by the area gives the rate of change of volume:
8 m³/min = (14.4 m²)(h')
h' = (8 m³/min)/(14.4 m²) = 5/9 m/min
