Under certain conditions the pressure of a gas varies directly with the temperature. When the pressure is 900 psi, the temperatu
Crank

Answer:

180psi

Step-by-step explanation:

Step one:

given data

P1= 900 psi

T1= 350°C

P2=?

T2=70°C

Required

The final pressure P2

<em>Gay-Lussac's Law: The Pressure Temperature Law. This law states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. With an increase in temperature, the pressure will go up</em>

Applying the expression

P1/T1= P2/T2

substitute:

900/350= P2/70

2.57=P2/70

cross multiply

P2= 2.57*70

P2=180psi

What is the complete factorization of the polynomial below
zepelin [54]

Answer:

B. (x+4)(x+i)(x-i)

Step-by-step explanation:

Let P(x)=x^3-4x^2+x-4

We can factor this polynomial by grouping:

P(x)=x^2(x-4)+1(x-4)

We factor further to obtain:

P(x)=(x^2+1)(x-4)

P(x)=(x^2-\sqrt{-1}^2)(x-4)

We apply difference of two squares to get:

P(x)=(x-i)(x+i)(x-4)
