Answer:
$71.20
Step-by-step explanation:
Multiply 89 to .2 and you get 17.8 then you subtract that from the originat cost.
C) p(x) has a zero between x=2 and x=4
For a polynomial p(x), means that, when p(x) is divided by , the remainder is .
This is called the remainder theorem
Therefore , means that when p(x) is divided and is 1 and respectively.
Also the Intermediate value theorem says that, if p(a) and p(b) have opposite signs then there is a certain on where i.e there is a zero between and
Therefore the correct answer is C
30 x 4 + 4 x 4 and 4 x 4 + 4 x 30
