Answer:
C
Step-by-step explanation:
the only it has constant rate of change (slope, gradient or derivative at every point is equal)
Part a)
The shape of the pool is rectangular prism, so the volume of the pool will be:
Volume = Length x Width x Depth
Volume = 6 x 3 x 1 = 18 cubic meters
Density of water = 1 gram per cubic centimeter
Density of water = 1,000,000 gram per cubic meter
Density of water = 1000 kilogram per cubic meter
Mass, volume and density are related by the following equation:
Mass = Density x Volume
Using the values, we can write:
Mass of water in pool = 1000 x 18 =18,000 kilogram
Part b)
Mass of water added to pool = 6000 kilograms
Density of water = 1000 kilogram per cubic meter
Volume = Mass/Density
Volume of water in the pool = 6 cubic meter
Since Volume = Length x Width x Depth
6 = 6 x 3 x Depth
⇒ Depth = 1/3 meters
Hello :
answer A. f(x) = log(x + 1) – 1 because f(o) exist : f(o) = log(0+1)-1 = log(1)-1 =-1 ...log1=0
