The temperature, T (in degrees Kelvin), of an enclosed gas varies jointly wi
th the product of the
volume, V (in cubic centimeters), and the pressure, P (in kilograms per square centimeter). The
temperature of a gas is 294 K when the volume is 8000 cubic centimeters and the pressure is 0.75
kilogram per square centimeter. What is
the temperature when the volume is 7000 cubic
centimeters and the pressure is 0.87 kilogram per square centimeter?

K= ? Z=?

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.

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)
