The mass of an object is equal to the product of the object's density and volume.

the density of lead is 11.3 grams per cubic centimeter. if the volume of a piece of lead is 16 cubic centimeters, what is its mass?

a. 0.706 g
b. 1.42 g
c. 180.8 g
d. 165.0 g

0.706 grams

Step-by-step explanation:

Given : The density of lead is 11.3 grams per cubic centimeter.

            Volume of a piece of lead is 16 cubic centimeters.

To Find: Mass

Solution:

So, Mass = 0.706 grams

Hence If the volume of a piece of lead is 16 cubic centimeters, its mass is 0.706 g .

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
