1. a polynomial has a degree of 5 whose coeffiecients are real numbers has the zeros 2, 4i, and 4 + i. Idenitfy the remaining zeros.
A: -4i, 4-i
B: -2, -4i, 4-i
C: 4i, -4-i
D: -4i, 4+i
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.
A: P=1/120 T
B: P= 1/16 T
C: P=16T
D: P= 120T
Hello, Brooke!
1. A polynomial has a degree of 5 whose coeffiecients are real numbers
has the zerosand
. . Identify the remaining zeros.
\;-4i,\;4-i\qquad B)\;-2,\;-4i,\;4-i\qquad C))
\;-4i,\;4+i)
Complex roots always appear in conjugate pairs.
. . Ifis a root, then
is a root.
. . Ifis 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.
\; P = \frac{1}{120}T\qquad B)\;P= \frac{1}{16}T\qquad C)\;)
\; P= 120T)
"The pressure is directly proportional to the termperature": .
We are told thatwhen
.
So we have: .
Therefore, the equation is: .. . . answer choice
