Answer:
The air is .6m^3
Step-by-step explanation:
The volume of a cube is
V = s^3 where s is the side length
The volume of the tank is
V = 1^3 = 1 m^3
The volume of the water is 1 by 1 by .4
V = l*w*h
= 1 *1*.4
= .4 m^3
The difference must be filled by air
1- .4 = .6 m^3
The air is .6m^3
Answer:
h(x) = (-2x + 4)(3x − 3 )
Step-by-step explanation:
each letter can be 1 of 26 letters
each number can be 1 of 10 digits
so you get
26 * 26 *26 * 10 *10 = 1,757,600 combinations
