Answer:
x²-(i-3)x- 3i
Step-by-step explanation:
What is a third-degree polynomial function P(x) with rational coefficients so that P(x) = 0 has roots −3 and i?
Given the toots of the polynomial to be -3 and i, the factors of the polynomial will be (x+3) and (x-i)
Taking the product
P(x) = (x+3)(x-i)
P(x) = x²-xi+3x-3i
P(x) = x²-(i-3)x- 3i
Hence the required polynomial is
x²-(i-3)x- 3i
Answer:
the correct answer is C
Step-by-step explanation:
first step you change the x and y powers to the square root(showing in the pic).
second the number outside of the parenthesis times the numbers inside the parenthesis and then you just figure it out how it works...

Step-by-step explanation:
Volume of a Sphere :
V = 


V = 


V =
(216)
(216 times 4, divided by 3)
V = 288
Now divide by 2, it's only half of a sphere.
