Answer:
Step-by-step explanation:
We want to write an equation for the polynomial function with roots;
and
Note that complex roots come in pairs and in conjugates.
Therefore
is also a root.
By the factor theorem:
(x-2), (x+3+5i), and (x+3-5i) are factors of the polynomial.
Let p(x) be the polynomial, then in factored form.
We expand now to get:
Simplify now
We expand further;
Answer
C) 325.41
Step by step explanation
The land-line telephone costs =$25.95
Utilities tax percentage = 4.5% = 4.5/100 = 0.045
Utility tax for amount $25.95 = 25.95*0.045
Utility tax = $1.17
The amount of telephone bill with tax = $25.95 + $1.17
= $27.12
There are 12 months in a year.
Telephone bill for a year = $27.12 * 12
= $325.44
Therefore, the nearest amount $325.41
You need to pay $325.41 as telephone bill for a year.
Thank you.
