Hello, Brooke!

1. A polynomial has a degree of 5 whose coeffiecients are real numbers

has the zeros and . . Identify the remaining zeros.

Complex roots always appear in conjugate pairs.

. . If is a root, then is a root.

. . If is a root, then is a root.

Answer choice .

2. An enclosed gas exerts a pressure P on the walls of its container.

This pressure is directly proportional to the temperature T of the gas.

If the pressure is 4 pounds per square inch when the temperature is 480° K,

identify the appropriate direct variation equation.

"The pressure is directly proportional to the termperature": .

We are told that when .

So we have: .

Therefore, the equation is: . . . . answer choice
