If the density of the mattress is 1000 kg/m³. Then the mass of the mattress will be 4800 kg.

<h3>What is density?</h3>

Density is defined as the mass per unit volume. It is an important parameter in order to understand the fluid and its properties. Its unit is kg/m³.

The mass and density relation is given as

mass = density × volume

The mattress of a water bed is 4.00 m long by 4.00 m wide and 30.0 cm deep. And the density of the mattress is 1000 kg/m³.

Then the mass of the mattress will be

M = 1000 x 4 x 4 x 0.3

M = 4800 kg

If f(x)=(x+3)³+4<br> let g(x)=f(x+1)-2<br> find when g(x)=12
Alla [95]

Answer:

Explanation:

g(x) = f(x + 1) - 2

g(x) = (x + 1 + 3)^3 -2

g(x) = (x + 4)^3 - 2

Now what are we supposed to do with this? I'm guessing we are to find what value of x will make g(x) = 12. If I'm wrong, leave a note in the form of a comment.

g(x) = 12

(x + 4)^3 - 2 = 12                 Add 2 to both sides.

(x + 4)^3 = 14                      Take the cube root of both sides.

x + 4 = cubrt(14)

x + 4 = 2.4101                      Subtract 4

x = 2.4101 - 4

x = -1.5899
