Step-by-step explanation:
This problem bothers on the density of substances
Given data
Mass of substance m= 16kg
Volume of substance v = 2L
the equation that relates the volume. V. to the mass, m is the expression for density
ρ= mass/volume
Substituting our given data
ρ= 16/2= 8kg/L
Using the density calculated above we can get the volume liters, of 128kg of liquid
8= 128/v
v=128/8
v= 16L
The volume is 16L
The density of a substance is expressed as the mass per unit volume
Answer:
All real numbers
Step-by-step explanation:
See the image.
Your supposed to add the like terms and 7x and 6x are like terms so you add those and get 13x and 9 and 2 are like terms and when you add them you get 11 and the answer of the first part of the equation is 13x + 11
Answer:
domain of y = sqrt (x+4) is [-4, +inf)
Step-by-step explanation:
[-4, +inf), -4 is included because sqrt(-4 + 4) is defined but is undefined at the points from (-inf, -5].
