Which of the following is a polynomial with roots 4, –2i, and 2i ?
Answers
x(x^2 + 4) - 4(x^2 + 4) = 0
x^3 + 4x - 4x^2 - 16 = 0
x^3 - 4x^2 + 4x - 16 = 0

The total cost (C) charged by the internet service provider = $65 + $18(n)
Step-by-step explanation:
Initial fee charged by the servic eprovider = $65
Cost per hour of labor for office internet installation = $18
The cost per hour be $18
Cost per two hours = 18 * 2 = $36
Cost per n number of hours = $18 (h)
where h represents the number of hours
The total cost (C) charged by the internet service provider = $65 + $18(n)

from the relation: (sin2(x) +cos2(x) =1 )
so , sin2(x)=1-cos2(x)
by subs. in the main eqn.
1-cos2(x) + cos(x) =1
by simplify the eqn.
cos(x) -cos2(x)=0
take cos(x) as a common factor
cos(x)* (1-cos(x))=0
then cos(x)=0 && cos(x)=1
cos(x)=0 if x= pi/2
& cos(x) = 1 if x = 0 , 2*pi
so the solution is x= {0,pi/2 , 2*pi}
Answer:
Which statements did you include in your answer?
Isolate sin(x) by adding 4 and taking the square root of both sides.
State that sin(x) = 2 or sin(x) = –2.
State that –2 and 2 are undefined values of the inverse sine function.
There are no solutions because –2 and 2 are not in the domain of the function.
